Toxic chemicals from sewage sludge used as fertilizer pose health risks to those who regularly consume products from farms that use it, in some instances raising cancer risk by “several orders of magnitude” over what is considered acceptable by the United States Environmental Protection Agency (EPA), federal officials said on Tuesday.
EPA’s draft risk assessment, Draft Sewage Sludge Risk Assessment for Perfluorooctanoic Acid (PFOA) and Perfluorooctane Sulfonic Acid (PFOS), is a scientific evaluation of potential health risks to humans associated with toxic per- and polyfluoroalkyl substances (PFAS) “forever chemicals” in biosolids, or “sewage sludge,” a press release from EPA said.
“EPA under President Biden’s leadership has taken unprecedented actions to advance research and science on PFAS and to protect people from these dangerous forever chemicals,” said Jane Nishida, EPA’s acting administrator, in the press release. “This draft assessment provides important information to help inform future actions by federal and state agencies as well as steps that wastewater systems, farmers and other stakeholders can take to protect people from PFAS exposure, while ensuring American industry keeps feeding and fueling our nation.”
The findings show that exposure to PFOA or PFOS — two types of forever chemicals — during sewage sludge use and disposal methods may pose human health risks. The three methods are: surface disposal in landfills, land application of biosolids and incineration.
Once the assessment is finalized, it will assist EPA and partners in understanding the public health impacts posed by forever chemicals in biosolids, as well as inform potential future actions that could help reduce exposure risk.
Wastewater gets conveyed to a treatment plant from businesses, households and industrial dischargers. The treatment processes produce a semi-solid product that is rich in nutrients called “biosolids” or “sewage sludge.”
“EPA typically uses the term ‘biosolids’ to mean sewage sludge that has been treated to meet regulatory standards and is thereby suitable to be land applied as a soil conditioner or fertilizer. In turn, biosolids can be beneficially reused as land applied fertilizer on agricultural fields or on nonagricultural lands to promote plant health and productivity,” EPA explained.
EPA’s draft risk assessment focused on a narrow and specific population that the agency considered most likely to have exposure to PFOS or PFOA from biosolids being applied to land or through the consumption of products produced on the land where biosolids were applied as fertilizer.
“The preliminary findings of the draft risk assessment indicate that there can be human health risks exceeding EPA’s acceptable thresholds, sometimes by several orders of magnitude, for some scenarios where the farmer applied biosolids containing 1 part per billion (ppb) of PFOA or PFOS (which is near the current detection limit for these PFAS in biosolids),” the press release said.
The risk assessment used scientific modeling of hypothetical health risks to humans who live on or near sites that have been impacted by PFOS or PFOA or for those who mostly rely on products from the sites, such as animal products, food crops or drinking water.
“EPA risk assessments follow a scientific process to characterize the nature and magnitude of health risks to children, adults, and the environment from pollutants based on modeled exposure scenarios. An environmental risk assessment considers three primary factors: 1) presence (i.e., how much of a pollutant is present in the environment); 2) exposure (i.e., how much contact a human or wildlife has with the pollutant); and 3) the toxicity of the pollutant (i.e., the health effects the pollutant causes in humans or wildlife),” EPA said.
The modeled scenarios included farms that used one application of 10 dry-metric-tons per hectare of the biosolids for 40 consecutive years.
The modeling also found human health risks above the EPA acceptable standards in scenarios where 1 part per billion of PFOS or PFOA was put in a clay-lined or unlined surface disposal unit.
Once the draft risk assessment is finalized, EPA will use it to “help inform future risk management actions for PFOA and PFOS in sewage sludge. For the incineration scenario, risk is not quantified due to significant data gaps,” the press release said.
The analysis did not suggest that the country’s general food supply was contaminated by biosolids containing PFOS or PFOA, but the U.S. Department of Agriculture and the Food and Drug Administration are conducting broad PFAS monitoring in the food supply and have taken actions to address products that have been impacted from imported and domestic sources.
According to the “best available data,” biosolids make up less than a percent of fertilized acreage of the nation’s productive agricultural lands annually. There are specific “hot spots” recognized by EPA, and certain farming operations could have higher PFOS or PFOA levels if they used contaminated sludge.
EPA said “further collaboration with impacted operations and other federal agencies will be important to fully understand risks and support impacted farmers.”
The analysis found that PFOS and PFOA risks of exposure from biosolids increased proportionally with how much of the chemicals were present.
“This means that if you lower the concentration of PFOA or PFOS in biosolids or the amount of biosolids applied to agricultural land, you lower the risk. The actual risks from exposure to PFOA or PFOS will vary at farms that land-apply biosolids or at biosolids disposal sites based on the amount of PFOA or PFOS applied, as well as geography, climate, soil conditions, the types of crops grown and their nutrient needs and other factors.,” EPA said.
The draft risk assessment’s findings highlight the importance of proactive state and federal policies to remove and control PFAS at their source.
“Moving forward, EPA is working to set technology-based limits on discharges from several industrial categories — including PFAS manufacturers, electro- and chrome-platers and landfills — under the agency’s Effluent Limitations Guidelines program,” the press release said. “Several states have begun monitoring for PFAS in sewage sludge and published reports and data that are publicly available.”

As a longtime book lover, I may be biased, but I think a full bookshelf is one of the most beautiful additions to a space. There’s nothing better than seeing a showcase of your favorite reads alongside a TBR list.
A bookcase, though, can of course be used for all sorts of purposes from placing your favorite photos of family and friends to showcasing treasured vintage finds.
Whatever the case, this guide will help you find the right sustainable bookshelf for your living room, office, or wherever you like to cozy up with a good read!
So what make a bookcase more sustainable? What makes a bookshelf non-toxic?
First of all: sustainable and non-toxic are two overlapping — but distinct — criteria. And both of those terms can come with a lot of opinions and varying definitions.
When it comes to sustainable bookcases, I look for:
- Responsibly Sourced Materials: most bookshelves are made primarily with wood. While natural, unsustainable wood sourcing can be a cause of deforestation, so we want to see that the wood was from responsibly managed forests or made from reclaimed or repurposed wood. Some bookshelves may feature metal, in which case recycled materials here are important.
- High Quality Construction: sustainability includes longevity — how long will you be able to use that furniture piece before it goes to the landfill and gets replaced? Look for transparency around craftsmanship and woodworking processes. Another sign of quality is the length of warranty a company has for its products.
- Ethically Made: this one is straightforward in theory — were the people making it paid fairly and working in safe conditions? — but is unfortunately not always easy to find information. In this category, I look for transparency in practices, what relationship the brand has with the manufacturer (some produce in-house which is the best case scenario for transparency!), where it was made, and how well the makers were paid.
Ideally a sustainable bookshelf would also be non-toxic — as toxic chemical fumes aren’t exactly sustainable! But this isn’t always the case. For example, if a company prioritizes upcycled materials, they don’t necessarily have control over what inputs were part of the original materials. And sometimes a company focuses more on ethical artisan partnerships and sustainable wood sourcing, more than, say, using non-toxic finishes.
But when it comes to non-toxic bookshelves, this is what I look for. (Note that non-toxic doesn’t necessarily mean safe for all chemical sensitivities. Nor does it mean zero potentially irritating chemicals.)
- Solid Wood (where possible): MDF or pressed wood contains glue to stick the various wood pieces together, which can contain added formaldehyde. I prefer solid wood, or if it is engineered wood, I’d make sure the company is transparent around the type of glue used and/or they at least have a product certification like GREENGUARD. (More on that in a second.)
- Low or Zero VOC Finishes: most wood furniture is completed with some sort of finish to provide a protection against scratches or moisture. Many of these finishes are synthetic, and some can contain high levels of toxic chemicals. Look for a natural finish like linseed oil or beeswax or a low VOC synthetic finish.
Relevant Certifications
You’ll see a few certifications referenced throughout this guide. Here’s what each one covers:
- FSC Certified = the wood sourcing was responsibly managed; this is not a finish, foam, or textile guarantee.
- GREENGUARD / GREENGUARD Gold Certified = the finished product was tested for low chemical emissions, including VOCs, with Gold representing the stricter tier.
- Fair Trade Certified
= verifies that a factory meets standards for fair wages, safe working conditions, and ethical labor practices. - Cradle to Cradle Certified (Gold) = evaluates a product or material across material health, circularity, clean air/climate, water/soil stewardship, and social fairness.
Where to Find Sustainable Bookcases and Shelving
I’m always a secondhand first proponent, and that goes for furniture, too. While your local thrift store might not have used bookshelves, check for dedicated furniture resale shops near you or estate sales. (I use EstateSales.net to find ones near me.) You can also find gently used pieces on online marketplaces like Facebook Marketplace, OfferUp or AptDeco.
If you can’t find something you love secondhand, and you don’t want to DIY your own bookshelf, then the next best choice is to shop from one of the sustainable furniture companies below. (If you’re simply looking for a bookstand, I’d suggest browsing Etsy for a collection of solid wood, bamboo, and reclaimed wood book stands and cookbook stands!)

Put your feet up and relax with the eco-friendly and non-toxic ottomans, benches, and poufs from these incredible sustainable furniture brands.
What makes an ottoman, pouf, or bench sustainable?
There are a lot of considerations that go into making sustainable furniture. Some brands may meet more of these criteria than others, and some criteria may be more or less important to you.
You might also engage with sustainability differently depending on your lifestyle, budget, aesthetic preferences, among other factors. But here’s a general idea of what to look for:
Look Secondhand
Used ottomans and benches are going to the most sustainable option since these furniture pieces have already been produced! Plus you’re preventing that furniture from heading to a landfill. You could browse an app like OfferUp or check your local Facebook Marketplace.
You can also check secondhand furniture sites like AptDeco and Chairish
Shopping for new sustainably-made ottomans and benches? Check out the following tips:
Eco-Conscious & Durable Materials
With the rise of fast furniture, the quality (and the sustainability) of materials used in furniture has declined. I’m consistently blown away by the incredible condition of so much vintage mid-century modern (1930s-1970s) furniture out there!
A sustainable ottoman (or sustainable bench) would be made durably so it lasts and would be constructed from responsibly sourced materials such as FSC-Certified and/or locally sustainably-harvested wood, recycled fabrics and organic natural fabrics for the upholstery, and non-toxic — ideally zero VOC — finishes. This guide has more non-toxic furniture brands.
Responsibly Made
Look into where the brand is producing their ottomans, benches, and/or poufs. Is it in their own workshop or a nearby production facility? Is it in a fair trade artisan workshop? A brand should have full transparency and traceability of their supply chain.
They also should ensure workers are earning living wages and work in safe environments. (This is where the overlap with non-toxic comes in — when there are toxic chemicals used in furniture, supply chain workers are exposed to these toxins in far greater quantities than consumers.)
Circular Practices
The EPA estimates that 12 million tons of furniture are thrown out annually. Yikes. A brand selling sustainable benches and ottomans would ideally consider the following:
- Quality construction so the furniture lasts a lifetime (or several)! If you’re moving a lot, it’s also worth considering how easy that piece of furniture is to move around and deconstruct/reconstruct if necessary. Though this probably is less of a concern with a smaller piece of furniture like a pouf, bench, or ottoman.
- Repairability. Is that material repairable? Does that brand have replacement parts? Is it a material that could be refinished or reupholstered easily? For example “vegan leather” (typically plastic) is very difficult to keep up or repair.
- Secondhand program or resellability. It would be incredible if the brand had a resale program for their furniture. Not many brands do, though. So you might also just think about if the style and quality of the piece would make it easy to sell again if you do think you might outgrow it.
