Can New York City Treat Its Food Scraps as More Than Trash?

News Feed
Monday, July 15, 2024

On an unseasonably sunny day in March, at a community garden in the Brooklyn neighborhood of Bushwick, Dan Gross and Shaq Benn moved piles of wood chips and hosed down shoulder-high windrows of compost. Tucked underneath elevated train tracks, Know Waste Lands is the home base of the compost-hauling nonprofit BK Rot. Its quarter-acre lot houses custom-built tool sheds and water pumps, solar panels for charging phones and e-bikes, and a motorized sifter designed by Benn. As the pair worked, a steady trickle of locals stopped at the entrance to drop off kitchen scraps—not trash, but the makings of “black gold.” Thanks to careful management, even on this balmy day the steaming heaps of rotting vegetables didn’t give off an offensive odor. “I actually like the smell,” Gross said during a break from work. BK Rot is part of a diverse ecology of community compost organizations throughout New York City. For decades, with crucial support via the city’s NYC Compost Project, community composters have taken a small but significant part of the roughly 4,000 tons of organic waste generated by New Yorkers every day and converted it into a valuable resource. Food scraps and landscaping debris, rather than going “out of sight” to landfills, where they emit significant greenhouse gases, are transformed into material that sustains local gardens, fortifies the city’s heat-mitigating tree population, and remediates contaminated soils. Meanwhile, local residents are educated and empowered to manage their own waste, less pollution goes into transporting and processing food scraps, and community bonds are deepened. Community composting is a cherished part of many neighborhoods throughout New York. But its future is unclear. In November of last year, under Mayor Eric Adams and his sanitation department’s new commissioner, Jessica Tisch, the NYC Compost Project was cut entirely from the city budget. So was a contract with the nonprofit GrowNYC, which operated dozens of food-scrap drop-off locations throughout the city, processing millions of pounds of scraps each year. The cuts decimated community compost operations, costing dozens of jobs, closing down numerous processing locations, and curtailing educational programming. All to save around $7 million, a mere 0.006 percent of the city’s budget, or “less than a rounding error,” Manhattan Borough President Mark Levine said at a recent rally in front of New York City Hall. After an immense pressure campaign by activists, members of the city council, and other elected representatives, funding was restored at the end of June. With the vote, the budget for community compost was placed under the New York City council instead of the city’s sanitation department. “I’m hoping that this will be less up for negotiation each budget season,” says Anna Sacks, legislative chair for the Manhattan Solid Waste Advisory Board and co-founder of NYC’s SaveOurCompost coalition. “There’s so much more that we could do, and it ends up by necessity concentrating our efforts on to preserving what’s in existence, versus imagining a more expansive alternative future.” Saved From the Trash The NYC Department of Sanitation began supporting community composting in the early 1990s. It launched the NYC Compost Project, establishing and supporting compost operations at four of the city’s botanical gardens, along with satellite facilities at various parks and community gardens. The project also supported the beloved, now discontinued Master Composter program, to which many community composters in New York trace their roots. As community composting evolved, the city also advanced its own curbside collection programs, which rely on contractors for transport and off-site processing. In 2016, the city’s anaerobic biogas digester in Newtown Creek, developed in partnership with the National Grid energy company, began accepting food scraps. Its giant “digester eggs” receive a mixture of organic waste streams, including sewage. Rather than creating compost, though, the process produces methane that is burned for energy (and profit), along with an organic sludge that is landfilled. Besides not building soil, critics point out, the system entrenches reliance on fossil fuel infrastructure. Often, the methane, a powerful greenhouse gas, is simply flared into the atmosphere. Biogas and centralized organic waste collection are the other side of the community compost coin. They represent what Guy Schaffer, author of Composting Utopia: Experimental Infrastructures for Organics Recycling in New York City, calls “neoliberal waste management.” “There’s this pattern that happens in a lot of places, where people try to fix waste problems by creating new markets for waste,” said Schaffer, who is also a board member of BK Rot. In his analysis, such market “solutions” tend to perpetuate social inequities. “We can see the setting of a price on waste so that people have to pay for it, but that often creates a situation where waste winds up getting recuperated by the most marginalized people.” BK Rot is a somewhat unique example among the city’s community composters. Although it is largely funded by grants, including as part of a crop of new additions to the restored NYC Compost Project, it operates like a business: In exchange for a fee, the nonprofit collects organic scraps from residences and small businesses, hiring local Black and brown youth who haul the material away by cargo bike to be windrowed. The resulting compost can be bought directly onsite, or at local food co-ops, where it is sold in smartly branded pouches resembling bags of designer coffee. “We can create a system that can actually create green jobs for young people, that can serve as a fossil-fuel-free waste alternative—and even reframe what waste is.” The upshot of BK Rot’s work is that, along with a valuable resource—they claim to have diverted 1.5 million pounds of organic waste to date—it creates work opportunities within a community where gentrification has made such opportunities increasingly scarce. Meanwhile, fewer food scraps fill trash bags on the street corner to attract rats, or fill up trucks and landfills that typically operate near marginalized neighborhoods. “Bushwick is such a fascinating focal point for thinking about waste inequity and intersectional inequities as they relate to environmental justice,” Nora Tjossem, co-director of BK Rot, said. “[BK Rot] really is an answer to say, ‘Well, what if we can dream up a different system? What if we can address all of these problems at once, or at least a great number of them?’ . . . We can create a system that can actually create green jobs for young people, that can serve as a fossil-fuel-free waste alternative—and even reframe what waste is.” Grab a Pitchfork Each instance of community compost takes a slightly different approach, responding to local conditions and needs. They are what Schaffer calls experimental infrastructures, alternatives to the status quo. To address the income inequities of the neighborhood where it operates, BK Rot takes a labor-centric view, making its priority one of engaging and employing local youth. Other composters may rely more on volunteer labor and try to leverage the value of the material itself, using markets to foster different relationships between communities and waste. “These interventions are not idealistic escapes from reality,” Schaffer writes in Composting Utopia. “They remake the systems they inhabit. Community composters aren’t trying to figure out if community compost will or won’t work as a solution to New York City’s waste problems, they’re building worlds in which community compost does work, and inviting people to stop by and grab a pitchfork.” Despite the struggles for funding, community composters remain supportive of the city’s various efforts to divert organic waste. In April 2023, Mayor Adams unveiled an initiative called PlaNYC: Getting Sustainability Done. Among its promises were an expansion of tree canopies, curbside rain gardens, and green jobs, along with a reduction in emissions. All these aims are helped by community compost, which makes the recent struggles over funding and access to land particularly vexing to community composters, who see their efforts as complementary, while noting that the city has ample funds for projects like a quarter-billion-dollar police training facility. The Struggle Continues The city’s restoration of the NYC Compost Project in June means that community compost can continue developing, though the form that will take is undetermined. A number of small operations will receive restored funding. “GrowNYC is no longer operating the food-scrap drop-off sites in the green market,” Sacks said. “As a result, there was money that we could reallocate to other groups. Something we as a coalition have wanted to see for a long time is not just the established community composting groups being funded by the city, but new ones that are doing great work also being funded.” “Community composters aren’t trying to figure out if community compost will or won’t work as a solution to New York City’s waste problems, they’re building worlds in which community compost does work, and inviting people to stop by and grab a pitchfork.” But the cuts have had lasting consequences. The nonprofit Big Reuse lost access to its Brooklyn Salt Lot site in January as result of rezoning. Since 2011, it had operated a state-of-the-art composting facility underneath the 59th Street Bridge in Queens, composting over 3 million pounds of Parks Department leaves and wood chips. Just last year, it generated 700 cubic yards of compost that went to 154 different parks, schools, community gardens, and various greening projects. The cuts to the Community Compost Project also forced Big Reuse to reduce its staff, and coincided with the loss of access to its Queensbridge site. The city’s Parks Department claimed it needed the site for a parking lot, despite owning an empty lot next door. All of this underscores the crucial role of land, and of a positive relationship with the city, in enabling community composting. The Queensbridge site closed despite immense public outcry, expressed through representatives, petitions, letters, and public testimony at various hearings, press conferences and rallies. “It’s literally paving paradise to put up a parking lot,” said Eric Goldstein, a lawyer with the National Resources Defense Council who works to protect community composting. Other community composting operations have been disrupted at least in part, including the Lower East Side Ecology Center, Earth Matter, and all four botanical gardens. Still, many of the city’s leaders do see the value of community compost. Twenty-nine out of 51 city council members, and four of the five borough presidents, signed letters to the mayor and New York Department of Sanitation supporting this summer’s restoration of funding to community composters. More than 49,000 New Yorkers also signed a petition demanding the same, in an effort organized by the SaveOurCompost coalition. In parallel with the city’s expanding curbside program, community composters will again have the means to develop experimental infrastructures, while also filling the gaps within the city’s waste operations. With proper support, the diverse network of community compost operations can offer a meaningful alternative to centralized, carbon-intensive systems, which in New York currently capture only about 5 percent of organics in the waste stream. The hope among community composters is that the value of what they do is now clear to the city and the public alike, and that New Yorkers will treat food scraps not as trash but an opportunity to improve life in the city. “I hope that all this drama results in a broader public understanding of what composting is and what is required as a land-based movement,” Lopez said. “Invisibilization of waste is what I believe the mayor and [the department of sanitation] want to make happen. This allows [and] demands the public not think about it once it leaves their home. Community composting humanizes ‘waste’ and transforms it into a local resource and tool for raising ecological literacy, civic engagement, physical activity, and local responsibility for reducing our own impact in environmental injustice.” The post Can New York City Treat Its Food Scraps as More Than Trash? appeared first on Civil Eats.

RFK Jr. champions ban on artificial food dyes as states follow suit

Twenty states have introduced nearly 40 bills targeting synthetic dyes within the first three months of 2025

In addition to his fight against ultra-processed foods and seed oils, Health and Human Services Secretary Robert F. Kennedy Jr. is pushing to ban artificial food dyes from the nation’s food supply — and many states are following suit. Last week, West Virginia Gov. Patrick Morrisey signed into law a bill that was passed earlier this month by state lawmakers banning seven food dyes commonly found in food products and drugs. The ban applies to Red No. 3, Red No. 40, Yellow No. 5, Yellow No. 6, Blue No. 1, Blue No. 2 and Green No. 3 along with the preservatives butylated hydroxyanisole and propylparaben. “West Virginia ranks at the bottom of many public health metrics, which is why there's no better place to lead the Make America Healthy Again mission,” Morrisey said in a statement obtained by CBS News, citing RFK Jr.’s ongoing campaign. “By eliminating harmful chemicals from our food, we're taking steps toward improving the health of our residents and protecting our children from significant long-term health and learning challenges.” Starting Aug. 1, the dyes will be banned from meals served through school nutrition programs, according to the governor's office. On Jan. 1, 2028, the dyes and the two preservatives will not be allowed in drugs and foods sold in the state. According to the Environmental Working Group, a food safety advocacy group, 58 states have introduced legislation targeting artificial food dyes and food chemicals. Twenty of those states — including Arizona, Oklahoma, West Virginia and New York — have introduced nearly 40 bills within the first three months of this year. Arizona’s H.B. 2164, for example, would prohibit public schools from serving or selling foods containing the following additives: Red No. 3, Red No. 40, Yellow No. 5, Yellow No. 6, Blue No. 1, Blue No. 2, Green No. 3, potassium bromate, propylparaben, titanium dioxide and brominated vegetable oil (BVO). Additionally, New York’s S. 1239 and A.B. 1556 would ban the sale, distribution and production of food products containing Red No. 3, potassium bromate and propylparaben. It would also ban public schools from serving or selling foods containing Red No. 40, Yellow No. 5, Yellow No. 6, Blue No. 1, Blue No. 2 and Green No. 3. The recent legislation comes after California enacted the California Food Safety Act back in 2023. The law prohibits the use of four harmful additives — potassium bromate, propylparaben, Red No. 3 and BVO — in food products sold, manufactured or distributed in the state. Last year, California also enacted the California School Food Safety Act, which bans Red No. 40, Yellow No. 5, Yellow No. 6, Blue No. 1, Blue No. 2 and Green No. 3 from food served in public schools. Concerns about artificial food dyes have regained traction in the wake of the Trump administration. RFK Jr. and supporters claim that synthetic dyes are both unnecessary and harmful, pointing to reports linking such dyes to behavioral problems in children.  Most recently, RFK Jr. urged CEOs of several food industry giants — including PepsiCo, General Mills, Smucker's, Kraft Heinz, and Kellogg's — to eliminate artificial food dyes from their products. The secretary “expressed the strong desire and urgent priority of the administration to remove [Federal Food, Drug, and Cosmetics Act, or FD&C] colors from the food supply,” said Melissa Hockstad, president and CEO of the Consumer Brands Association, in a readout first reported by Food Fix. RFK Jr. reportedly “wants this done before he leaves office” and expects “real and transformative” change by “getting the worst ingredients out” of food. The readout also included a statement from Kyle Diamantas, Acting Deputy Commissioner for Human Foods at the U.S. Food and Drug Administration (FDA), who attended the closed-door meeting. Diamantas “recognized the industry can’t [eliminate harmful colorants and additives from the food supply] alone and that FDA will step up and work with [industry and stakeholders] to reinforce the need for a federal framework and avoid state patchworks,” per the readout.

They include Blue No. 1, Blue No. 2, Green No. 3, Orange B, Red No. 40, Yellow No. 5, Yellow No. 6, Red No. 3 and Citrus Red 2. In January, the FDA banned Red No. 3 from the nation’s food supply in response to a 2022 color additive petition filed by two dozen food safety and health advocates. The petition found that Red No. 3 causes cancer in male laboratory rats exposed to high levels of the dye. Although similar effects were not observed in other animals and humans, they were enough for the FDA to issue a ban. Red No. 3 — which gives certain foods and drinks a bright, cherry-red hue — is commonly found in candies, artificial fruit products, processed meats, frozen desserts and baked goods and snacks. “Manufacturers who use FD&C Red No. 3 in food and ingested drugs will have until January 15, 2027, or January 18, 2028, respectively, to reformulate their products,” the FDA said in a statement. “Consumers could see FD&C Red No. 3 as an ingredient in a food or drug product on the market past the effective date in the order if that product was manufactured before the effective date.” Read more about food additives:

Plastics Are Seeping Into Farm Fields, Food and Eventually Human Bodies. Can They Be Stopped?

Around the world, plastics are finding their way into farm fields

KAMPALA, Uganda (AP) — In Uganda's Mbale district, famous for its production of arabica coffee, a plague of plastic bags locally known as buveera is creeping beyond the city. It's a problem that has long littered the landscape in Kampala, the capital, where buveera are woven into the fabric of daily life. They show up in layers of excavated dirt roads and clog waterways. But now, they can be found in remote areas of farmland, too. Some of the debris includes the thick plastic bags used for planting coffee seeds in nurseries.Some farmers are complaining, said Wilson Watira, head of a cultural board for the coffee-growing Bamasaba people. “They are concerned – those farmers who know the effects of buveera on the land,” he said.Around the world, plastics find their way into farm fields. Climate change makes agricultural plastic, already a necessity for many crops, even more unavoidable for some farmers. Meanwhile, research continues to show that itty-bitty microplastics alter ecosystems and end up in human bodies. Scientists, farmers and consumers all worry about how that's affecting human health, and many seek solutions. But industry experts say it’s difficult to know where plastic ends up or get rid of it completely, even with the best intentions of reuse and recycling programs. According to a 2021 report on plastics in agriculture by the United Nations Food and Agriculture Organization, soils are one of the main receptors of agricultural plastics. Some studies have estimated that soils are more polluted by microplastics than the oceans.“These things are being released at such a huge, huge scale that it’s going to require major engineering solutions,” said Sarah Zack, an Illinois-Indiana Sea Grant Great Lakes Contaminant Specialist who communicates about microplastics to the public. Why researchers want to study plastics in farm fields Micro-particles of plastic that come from items like clothes, medications and beauty products sometimes appear in fertilizer made from the solid byproducts of wastewater treatment — called biosolids — which can also be smelly and toxic to nearby residents depending on the treatment process used. Some seeds are coated in plastic polymers designed to strategically disintegrate at the right time of the season, used in containers to hold pesticides or stretched over fields to lock in moisture.But the agriculture industry itself only accounts for a little over three percent of all plastics used globally. About 40% of all plastics are used in packaging, including single-use plastic food and beverage containers.Microplastics, which the National Oceanic and Atmospheric Administration defines as being smaller than five millimeters long, are their largest at about the size of a pencil eraser. Some are much smaller.Studies have already shown that microplastics can be taken up by plants on land or plankton in the ocean and subsequently eaten by animals or humans. Scientists are still studying the long-term effects of the plastic that's been found in human organs, but early findings suggest possible links to a host of health conditions including heart disease and some cancers.Despite “significant research gaps,” the evidence related to the land-based food chain “is certainly raising alarm,” said Lev Neretin, environment lead at the FAO, which is currently working on another technical report looking deeper into the problem of microplastic pollution in soils and crops.A study out this month in the Proceedings of the National Academy of Sciences found that microplastics pollution can even impact plants' ability to photosynthesize, the process by which they turn light from the sun into energy. That doesn't “justify excessive concern” but does “underscore food security risks that necessitate scientific attention,” wrote Fei Dang, one of the study's authors. Climate change making matters worse The use of plastics has quadrupled over the past 30 years. Plastic is ubiquitous. And most of the world's plastic goes to landfills, pollutes the environment or is burned. Less than 10% of plastics are recycled.At the same time, some farmers are becoming more reliant on plastics to shelter crops from the effects of extreme weather. They're using tarps, hoop houses and other technology to try to control conditions for their crops. And they're depending more on chemicals like pesticides and fertilizers to buffer against unreliable weather and more pervasive pest issues.“Through global warming, we have less and less arable land to make crops on. But we need more crops. So therefore the demand on agricultural chemicals is increasing,” said Ole Rosgaard, president and CEO of Greif, a company that makes packaging used for industrial agriculture products like pesticides and other chemicals.Extreme weather, fueled by climate change, also contributes to the breakdown and transport of agricultural plastics. Beating sun can wear on materials over time. And more frequent and intense rainfall events in some areas could drive more plastic particles running into fields and eventually waterways, said Maryam Salehi, an associate professor of civil and environmental engineering at the University of Missouri. Can agriculture escape the plastic problem? Neretin said the FAO produced a provisional, voluntary code of conduct on sustainable management of plastics in agriculture. But without a formal treaty in place, most countries don't have a strong incentive to follow it.“The mood is certainly not cheery, that's for sure,” he said, adding global cooperation “takes time, but the problem does not disappear.”Without political will, much of the onus falls on companies.Rosgaard, of Greif, said that his company has worked to make their products recyclable, and that farmers have incentives to return them because they can get paid in exchange. But he added it's sometimes hard to prevent people from just burning the plastic or letting it end up in fields or waterways. “We just don’t know where they end up all the time,” he said.Some want to stop the flow of plastic and microplastic waste into ecosystems. Boluwatife Olubusoye, a PhD candidate at the University of Mississippi, is trying to see whether biochar, remains of organic matter and plant waste burned under controlled conditions, can filter out microplastics that run from farm fields into waterways. His early experiments have shown promise.He said he was motivated by the feeling that there was “never any timely solution in terms of plastic waste" ending up in fields in the first place, especially in developing countries.Even for farmers who care about plastics in soils, it can be challenging for them to do anything about it. In Uganda, owners of nursery beds cannot afford proper seedling trays, so they resort to cheaply made plastic bags used to germinate seeds, said Jacob Ogola, an independent agronomist there.Farmers hardest hit by climate change are least able to reduce the presence of cheap plastic waste in soils. That frustrates Innocent Piloya, an agroecology entrepreneur who grows coffee in rural Uganda with her company Ribbo Coffee. "It's like little farmers fighting plastic manufacturers,” she said.Walling reported from Chicago.The Associated Press’ climate and environmental coverage receives financial support from multiple private foundations.

L.A. fire contaminant levels could sicken the marine food chain, new tests show

Levels of lead and other heavy metals spiked in L.A.'s coastal waters after the January fires, raising serious concerns for the long-term health of the marine food chain.

Levels of lead and other heavy metals spiked in the coastal waters off Los Angeles after January’s fires, raising serious concerns for the long-term health of fish, marine mammals and the marine food chain, according to test results released Thursday by the nonprofit environmental group Heal the Bay.For human surfers and swimmers, the results were somewhat encouraging. Contaminant levels from sampled water weren’t high enough to pose likely health risks to recreational beachgoers. But tests of seawater collected before and after the heavy rains that came in late January, after the fires abated, identified five heavy metals — beryllium, copper, chromium, nickel and lead — at levels significantly above established safety thresholds for marine life.Even at relatively low concentrations, these metals can damage cells and disrupt reproduction and other biological processes in sea animals.The metals also accumulate in the tissues of animals exposed to them, and then make their way up the food chain as those organisms are eaten by larger ones.“Most of these metals are easy to transfer through the food web and impact humans directly or indirectly, via food or drinking water,” said Dimitri Deheyn, a marine biologist at UC San Diego’s Scripps Institution of Oceanography. All are found in dust and rocks, and aren’t harmful in the context of those minute, naturally-occurring exposures. “That is why these elements are dangerous,” Deheyn said. “Our body is designed to take them up, but we are usually exposed to only a small amount of it.”On Jan. 24 and Jan. 25 — before the rain that came the following week — Heal the Bay staff collected seawater samples from eight locations along the coastline in or near the Palisades burn scar, in addition to control samples well outside the burn zone at Paradise Cove in Malibu and Malaga Cove in Palos Verdes Estates.They took additional samples on Jan. 28, after the first major storm in months dropped half an inch of rain on the L.A. basin and flushed debris into the sea.They tested for 116 pollutants. The vast majority were either not present or detected in only minuscule amounts in almost all the samples collected.But levels of beryllium, copper, chromium, nickel and lead were two to four times higher than the maximum allowed under California state law at Big Rock Beach in Malibu, where the wreckage of several destroyed houses still lie on the sand. “That’s not surprising as that’s where we have burned debris within the high tide line, [where] every minute of every day the ocean is lapping more and more contaminants into the sea,” said Heal the Bay Chief Executive Tracy Quinn.At the Santa Monica Pier and Dockweiler Beach, both of which are south of the burn scar, levels of both lead and chromium were roughly triple California’s safety threshold for marine life. At the Santa Monica test location after the rains, the level of beryllium — a metal that is toxic to fish and corals and causes respiratory distress in humans — was more than 10 times the maximum limit allowed.Further study is needed to determine whether fire-related contaminants are pooling in those areas or if the high levels are coming from another source of pollution, Quinn said. “We don’t recommend that people consume fish that are caught in the Santa Monica Bay right now,” Quinn said.The levels in these first results suggest that more testing is warranted, said Susanne Brander, an associate professor and ecotoxicologist at Oregon State University. “Anytime there’s a large residential wildfire, this is the kind of contamination you’re going to see,” she said. “I would look at these results and say, OK, we need to test soils, we need to test drinking water,.”Quinn noted several limitations in Heal the Bay’s data. The samples were collected in late January, and may not be representative of current ocean conditions. There are also no baseline data showing prefire conditions in the same area to which they could compare their samples, because there are no regular testing programs for these contaminants, she said.The organization also sampled 25 different polycyclic aromatic hydrocarbons, organic compounds that form when oil, wood or garbage burns. The organization expects results in the coming weeks, Quinn said. January’s fires and the heavy rains that followed sent unprecedented amounts of ash, debris and chemical residue coursing into the sea via the L.A. region’s massive network of storm drains and concrete-lined rivers.The Palisades and Eaton fires burned more than 40,000 acres and destroyed at least 12,000 buildings. In the months since they erupted, the remnants of cars, plastics, batteries, household chemicals and other potentially toxic material have continued to wash into the sea and up onto beaches.“I don’t think there’s a precedent for this kind of input into the ocean ecosystem,” marine biologist Noelle Bowlin said in January.In addition to fire contamination, California’s sea life is also under threat from an outbreak of domoic acid, a neurotoxin released by some marine algae species.Hundreds of animals have washed up sick or dead along California’s southern and central coasts in recent weeks, in the fourth domoic acid event in as many years.While nutrients such as sulfate and phosphorous that feed harmful algae were among the substances the fires released into the sea, Heal the Bay said it has not found a correlation between fire-related pollution and the outbreak now sickening marine animals.Understanding all of the effects that heavy metals, chemicals, bacteria and other pollutants released by the fire will have on the marine ecosystem “will take a huge, collaborative effort,” said Jenn Cossaboon, a fourth-year student at the UC Davis School of Veterinary Medicine who recently finished a doctorate on endocrine disruption in fish.“Species at each level of the food chain, from invertebrates to fish, birds, marine mammals and humans, can be affected differently based on their physiology and feeding strategies,” she said. “It will be very important to connect each of these pieces of the puzzle to really understand the impacts on the food web.”

How Microplastics Get into Our Food

Kitchen items—sponges, blenders, kettles—are abundant sources of microplastics that we all consume

When Amy Lusher moved in with her partner, one of the first things she did was get rid of all the plastic kitchenware in their household and replace it with items made of glass, wood and stainless steel. As a senior researcher in microplastics at the Norwegian Institute for Water Research, Lusher was acutely aware of how all the chopping, whisking, scraping and heating we do when preparing meals may release tiny particles of plastic into the food we eat. “It’s coming from our cooking. It’s coming from our packaging. It’s in most of our bottles,” she says.By now scientists like Lusher have found microplastics coming off dishwashing sponges, blenders, kettles—you name it. According to one 2024 study, plastic cookware may contribute thousands of microplastic particles each year to homemade food. Old plastic kitchenware was the worst culprit, and the researchers also concluded that microplastic shedding may be exacerbated by heating cookware or using hard or sharp utensils on it.Researchers have been trying for years to determine how many microplastic particles humans ingest when consuming everything from seafood to beer to honey. According to one estimate, every American consumes between 39,000 and 52,000 microplastic particles every year.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing.

Some are directly manufactured by humans, such as beads in exfoliating scrubs or glitter. Others result from environmental degradation of larger objects, such as plastic bottles or toys. “Microplastics are released in quantities far beyond human imagination,” says Lei Qin, a food scientist at Dalian Polytechnic University in China. By one estimate, 10 to 40 million metric tons of microplastics are released into the environment per year—about two to six times the weight of the Great Pyramid of Giza.They then accumulate inside our body. Studies have found microplastics in human brains (roughly the amount in a heaping teaspoon of table salt), as well as in our stomach, lungs and bones. Researchers have linked microplastics with a higher risk of stroke, inflammatory bowel disease and dementia. “We are at an early stage, but there is growing evidence that exposure to microplastics is linked to inflammation, coronary artery disease and neurodegenerative impairment,” says John Boland, a chemist at Trinity College Dublin. And although scientists have been looking for a while now at how much microplastic we may be ingesting with seafood or tap water, “it’s only really been in the last few years that we’ve started looking at exposure through things that we touch, things that we handle, especially in the kitchen,” Lusher says.To explore what is it exactly that happens with plastics in the kitchen, Lusher and her colleagues from the U.K. and Norway prepared jelly. They used either old or new plastic cookware to heat water, stir the jelly mixture, store it, chill it and cut it into pieces. The result: jelly prepared with new plastic cookware had about nine microplastic particles per sample on average, and jelly made with the old plastic cookware had 16. In other words, when jelly was made with worn-out items, it had 78 percent more microplastics than when it was prepared with new ones. "[Old cookware items] tend to release more plastic, probably because they’ve already become brittle,” Lusher says.Other research also lends evidence that wear and tear generates high levels of microplastic particles. Take cutting boards: in one study, when plastic boards were used to cut meat, up to 196 microplastic particles were incorporated into each ounce of meat, while none were found in meat that had been prepared on a bamboo board. Slicing ingredients and pushing a knife along the board to move them may also be worse than simply pressing with a knife to chop them, another study showed. “It’s the friction, the metal against the plastic,” Lusher says.Friction is also the mechanism by which blenders with plastic jars can release large amounts of microplastics. When scientists in Australia used a blender to crush ice blocks, the way you might when making, say, a frozen margarita, they found that billions of plastic particles were released in just 30 seconds of blending. “If the ice block has a sharp edge, like some hard food, it can peel off lots of plastic,” says Cheng Fang, a chemist at the University of Newcastle, Australia, and the study’s senior author.Scrubbing dishes with a sponge can also release hundreds of tiny plastic particles in just 30 seconds. The good news is that rinsing the dishes well afterward removes most of the residue. The bad news: the sponge microplastics go down the drain and accumulate in the environment, so they may end up in our food anyway.Opening and closing plastic bottles—which also creates friction—can also generate microplastic residues. “You’re shearing off plastic pieces all the time,” Boland says. In fact, according to one study, most microplastics in bottled water originate from twisting the cap. Each time you open and close a plastic bottle, the study found, you produce about 500 microplastic particles.Heating plastic kitchenware is a source of particles as well. Warming it up, like you may do in a microwave, Boland says, “dramatically accelerates the release of microplastics.” In a 2025 study, disposable plastic cups that were filled with scalding 95-degree-Celsius water released 50 percent more microplastics than cups filled with cooler, 50-degree-C water. Plastic kettles, too, could be a problem. The simple act of boiling water in a new kettle will leave you with between six million and eight million microplastic particles per cup, Boland and his colleagues found. Fewer and fewer particles are released with each successive use, however. In their study, after 40 boils in the kettle, only 11 percent of the initial microplastic load leached into the water.While it might be tempting to compare the numbers of microplastics released from various sources side by side, Lusher warns that it would be like comparing “apples to pears.” That’s because, she says, different labs use different methodologies: some count only larger microplastics, and others include nanoplastics (particles smaller than 0.001 mm). Some control for lab microplastic pollution, and others don’t. “If the handling of the data is totally different between each study, then there’s absolutely no point comparing it,” she says.Lusher says that this absence of methodological standards makes it hard to clearly identify the worst microplastic offenders in our kitchens. It still makes sense to “try to reduce the amount of plastic that we are exposed to,” simply because “we still don’t know what the long-term effects will be on health.”There are a few things you can do as well to lower the microplastic load produced in your kitchen. First of all, replace any plastic cutting boards with wooden ones if possible, and if you have a plastic kettle, consider swapping it for a stainless-steel product. (Make sure the lid is not plastic.) Substitute plastic storage containers with glass ones. If you do buy a new plastic kettle, boil and pour out the water in it a couple of times before preparing your first hot drink. And if you use plastic cutting boards, try to make sure they are relatively new.From a broader perspective, we could develop plastics that don’t shed easily into food. “If there are no alternatives, what can you do to the plastic to make it safer?” Boland says. Potentially, for example, manufacturers could create kettles with an inner lining that would prevent microplastic leakage during boiling. (Boland’s experiments suggest that it could be possible.) While such safer products may be technically feasible, he says, substantive change likely won’t happen without regulations that push the industry to make better plastics. “We need the regulators to drive industry to do the right thing,” he says.

Amazing iguanas conquered Fiji after a 5,000-mile journey

Iguanas are incredible reptiles that can live without food or water for long periods of time. They rafted 5,000 miles from North America to Fiji and Tonga. The post Amazing iguanas conquered Fiji after a 5,000-mile journey first appeared on EarthSky.

For many years, scientists have wondered where the iguanas that inhabit the remote and isolated islands of Fiji and Tonga came from. Finally, a team of researchers from the University of California, Berkeley, and the University of San Francisco said on March 17, 2025, they have an answer. These reptiles likely arrived on the islands by rafting from western North America. This means the iguanas traveled 5,000 miles (8,000 km) on natural rafts across the Pacific Ocean. To solve the mystery, the researchers analyzed the DNA of more than 200 iguana specimens from museums around the world. They also discovered that the iguanas arrived on the islands about 34 million years ago, either as soon as the islands formed or shortly afterward. The scientists published their study in the peer-reviewed journal Proceedings of the National Academy of Sciences on March 17, 2025. Simon Scarpetta, the study’s lead author, is a herpetologist and paleontologist, former postdoctoral fellow at UC Berkeley, and current assistant professor in the USF Department of Environmental Sciences. Fiji and Tonga iguanas broke a record Iguanas are fascinating animals: They can change color, detach their tails, have a third eye on top of their heads, know how to swim and can dive for 30 minutes. But traveling 5,000 miles (8,000 km) from the west coast of North America to these distant islands is a big deal. The four species that inhabit the islands of Fiji and Tonga have earned the well-deserved record for the longest known transoceanic dispersal of any non-human terrestrial vertebrate. These iguanas belong to the genus Brachylophus. Although iguanas commonly float on natural rafts made of fallen trees and plants – and transport themselves using this system – making such a long journey seemed impossible. Jimmy McGuire, co-author of the study and professor of integrative biology and herpetology curator at the Museum of Vertebrate Zoology, said: That they reached Fiji directly from North America seems crazy. There are 45 species of Iguanidae that live in the Caribbean and the tropical, subtropical and desert regions of North, Central and South America. Therefore, scientists looked for the origin of the Brachylophus genus in nearer locations. Central and South America seemed more likely options than North America. 2025 EarthSky lunar calendar is available.

The mysterious origin of Brachylophus iguanas Seeing iguanas floating on rafts in the Caribbean is a common sight. In fact, this is what happened centuries ago, when they embarked on a 600-mile (970-km) journey from Central America to colonize the Galapagos Islands. Scientists hypothesized that, if this had occurred previously, the iguanas could have continued their journey further to reach Fiji and Tonga from the western Pacific. Researchers also proposed the idea that they could have arrived from tropical South America, via Antarctica or Australia. However, there is no genetic or fossil evidence to support these hypotheses. According to McGuire: When you don’t really know where Brachylophus fits at the base of the tree, then where they came from can also be almost anywhere. So it was much easier to imagine that Brachylophus originated from South America, since we already have marine and land iguanas in the Galapagos that almost certainly dispersed to the islands from the mainland. This is a Fiji banded iguana at the Vienna Zoo in Austria. Image via Robert F. Tobler/ Wikipedia (CC BY-SA 4.0). Their origin confirmed! Previous genetic analyses of some iguanid lizard genes were inconclusive about the relationship of Fiji and Tonga iguanas to the rest. A few years ago, during his postdoctoral studies, lead author Simon Scarpetta began a detailed investigation of all Iguania genera with the goal of clarifying the group’s family tree. McGuire explained that: Different relationships have been inferred in these various analyses, none with particularly strong support. So there was still this uncertainty about where Brachylophus really fits within the iguanid phylogeny. Simon’s data really nailed this thing. Scarpetta compiled DNA from genomic sequences of more than 4,000 genes and from tissues of more than 200 iguana specimens found in museum collections around the world. When comparing these data, one result stood out clearly: Fiji and Tonga iguanas are closely related to iguanas of the genus Dipsosaurus. The most widespread of this genus is the North American desert iguana, Dipsosaurus dorsalis, adapted to the scorching heat of the deserts of the southwestern United States and northern Mexico. Scarpetta stated that: Iguanas and desert iguanas, in particular, are resistant to starvation and dehydration, so my thought process is, if there had to be any group of vertebrate or any group of lizard that really could make an 8,000 kilometer journey across the Pacific on a mass of vegetation, a desert iguana-like ancestor would be the one. This is a male Brachylophus bulabula at the Berlin Aquarium in Germany. Image via JSutton93/ Wikipedia (CC BY-SA 4.0). The origin of the islands and their colonization In addition to demonstrating that Brachylophus iguanas did indeed arrive from North America, the scientists also established that they reached Fiji and Tonga around 34 million years ago. They rejected alternative models involving colonization from adjacent lands because they didn’t correspond with this period of time. In fact, biologists had previously proposed that Fijian and Tongan iguanas could have descended from an older, more widespread lineage in the Pacific (now extinct). However, the dates did not match. This exhaustive analysis also explains when the genetic divergence of Brachylophus iguanas from their closest relatives, the North American Dipsosaurus desert iguanas, occurred. The study suggests that Brachylophus iguanas may have even colonized the volcanic islands of Fiji and Tonga as soon as land emerged 34 million years ago or shortly after their formation, thus diverging from Dipsosaurus iguanas. According to Scarpetta: We found that the Fiji iguanas are most closely related to the North American desert iguanas, something that hadn’t been figured out before, and that the lineage of Fiji iguanas split from their sister lineage relatively recently, much closer to 30 million years ago, either post-dating or at about the same time that there was volcanic activity that could have produced land. This is a female Gau iguana. Image via Mark Fraser/ Wikipedia (public domain). How did they get to the islands? Despite being very resilient creatures, it’s still surprising they were able to undertake this adventure. Dispersal over water is the main way newly formed islands are populated with plants and animals. And this is quite impressive. Let’s imagine the situation … A modern-day sailor using the wind to reach Fiji from California would need about a month to get there. Can you imagine how long it would take the iguanas floating on a raft? Fortunately, iguanas are accustomed to going long periods of time without food or water. On the other hand, the rafts they traveled on were likely made of fallen trees and other plants. Fortunately, iguanas are herbivores, and the raft itself would have provided them with food. The dispersal of animals often leads to the evolution of new species and entirely new ecosystems. Other islands besides Fiji and Tonga may have also hosted iguanas, but volcanic islands tend to disappear as easily as they appear. Evidence of other Pacific Island iguanas, if they existed, has likely been lost. So Fiji’s iguanas are an outlier, lying alone in the middle of the Pacific. Unfortunately, all four species from Fiji and Tonga are listed as critically endangered. This is primarily due to habitat loss and exploitation by smugglers who fuel the exotic pet trade.

Bottom line: Iguanas are incredible reptiles that can live without food or water for long periods of time. This allowed them to travel 5,000 miles from North America to Fiji and Tonga and conquer the islands.
