Per- and polyfluoroalkyl substances, or PFAS, have taken on the nickname “forever chemicals” for their inability to break down in the environment. These chemicals, which are found in everything from food packaging to camping gear, are popular for their stain-, moisture- and grease-resistant properties, but they have been found to accumulate in the environment and in human bodies.
But now, researchers may have cracked a way to break down these chemicals and even some of their byproducts, which can be toxic, by using strains of bacteria.
A team of scientists led by University of Buffalo researchers found that the bacteria Labrys portucalensis F11 was effective at breaking down at least three types of PFAS, including the most common forever chemical, perfluorooctane sulfonic acid (PFOS), as well as 5:3 fluorotelomer carboxylic acid (FTCA) and 6:2 fluorotelomer sulfonate (FTS).

The bacteria was the most effective at breaking down PFOS, a chemical that was designated as hazardous by the U.S. Environmental Protection Agency (EPA) in 2024. It degraded more than 90% of the compound over a 100-day exposure and removed up to 96% of the PFOS after 194 days. During the first 100 days, the bacteria broke down as much as 58% of FTCA and 21% of FTS. The scientists published their findings in the journal Science of The Total Environment.
“The bond between carbon and fluorine atoms in PFAS is very strong, so most microbes cannot use it as an energy source,” Diana Aga, corresponding author of the study, said in a statement. “The F11 bacterial strain developed the ability to chop away the fluorine and eat the carbon.”
In addition to breaking down the PFAS, the bacteria also broke down the metabolites that occur after the PFAS degradation, with Labrys portucalensis F11 even breaking down or fully removing fluorine in some of the study results.
“Many previous studies have only reported the degradation of PFAS, but not the formation of metabolites. We not only accounted for PFAS byproducts but found some of them continued to be further degraded by the bacteria,” explained Mindula Wijayahena, first author of the study and a Ph.D. student in Aga’s lab.

This particular bacteria strain has been previously revealed to degrade fluorobenzene, a flammable and hazardous compound sometimes found in insecticides.
The discovery offers a novel method for cleaning up PFAS; other methods have primarily focused on adsorbing and removing the PFAS, but the bacteria could help break down these chemicals and minimize the amount of time they spend in the environment.
A 2024 study uncovered a way to track PFAS contamination to the source, and a separate study published in 2023 a potential water treatment that would use adsorbing materials and electro- and photochemical processes to destroy PFAS contaminants in drinking water supplies. Yet another separate study published in 2022 found a plant-based material that could help adsorb PFAS, which would then be digested by fungus.
The study authors using Labrys portucalensis F11 for PFAS metabolization will continue their research, noting that although the bacteria did break down the PFAS, it took nearly 200 days, and that was without other food sources present.
“We want to investigate the impact of placing alternative carbon sources alongside the PFAS. However, if that carbon source is too abundant and easy to degrade, the bacteria may not need to touch the PFAS at all,” Aga said. “We need to give the F11 colonies enough food to grow, but not enough food that they lose the incentive to convert PFAS into a usable energy source.”

Curating a conscious home is a thoughtful process involving much consideration — who made my products, how they were made, and what are they made from — and this guide aims to support you on your journey towards finding ethical and sustainable home decor you truly love.
What is Sustainable Home Decor?
Sustainable home decor includes any home decor that is made in a way that takes into consideration both the makers and the planet. Sustainable home decor will be ethically made using eco-friendly and natural materials. Eco-friendly decor will also be produced using sustainable supply chain practices. This includes using renewable energy and recycled or compostable packaging.
While there are numerous sustainable home decor brands, some of which are featured below, first consider what’s already been made in order to prevent contributing to new waste. Secondhand, used, or DIY home decor options are typically more sustainable than buying new.
What is Ethical and Fair Trade Home Decor?
Ethical and Fair Trade home decor is produced in a way that adheres to Fair Trade standards and is, ideally, Fair Trade Certified. Fair Trade means paying artisans and makers a fair, living wage and providing ethical working conditions. Ethical home decor also includes supporting goods made by artisans using traditional heritage techniques and art forms. Many cultures around the world are at risk of losing their age-old artisanal crafts forever in the age of mass manufacturing.
It’s important to note that sometimes a major brand may use an “eco” fiber while still supporting irresponsible labor practices, and excessive production amounts that inevitably lead to a lot of waste. This is not true sustainability in my mind!
Most artisan-made home decor is ethically produced and directly supports the makers. However, it’s important to check if a brand or marketplace is transparent about their business practices to ensure they are ethical or Fair Trade.
Where Can You Find Sustainable Home Decor?
In terms of environmental sustainability, looking secondhand and vintage is always a great first place to look for sustainable home decor.
But if you’ve scoured those options and haven’t found what you’re looking for and/or if you’re looking to financially support artisans and traditional crafts around the globe, this shopping guide is designed for you. You’ll discover many brands with artfully designed and artisan handmade goods for furnishing any space among this list of decor brands.
All of the brands in this guide use natural and/or recycled fibers and avoid the use of virgin synthetics like polyester; however, some brands do use materials that are not the most environmentally-friendly option on the market, such as conventional cotton.
And of course, I wanted to choose brands that followed slow, thoughtful production practices, prioritizing artisan handmade over factory labor and quality over quantity.
So without further ado, here are my favorite small-batch, artisan-made, and ethical home decor brands.

Take a look at why hemp is heralded as a hero material and discover 14 hemp clothing brands that have tapped into its sustainable potential.
The exploration of fabrics has always been a starting point for sustainable innovation in fashion. After all, fabrics provide tangible proof that change is possible while having a direct impact on the environment in one way or another. Plus fabrics are responsible for an outsized proportion of a fashion brand’s carbon footprint and overall environmental impact, including biodiversity loss and pollution.
So, What is Hemp Fabric?
Hemp is a bast fiber produced from the cannabis sativa plant, where every part of the plant can be utilized for over 25,000 industrial uses including clothing, biofuel, bricks, paper, and textiles.
Contrary to its popular association, hemp is actually the sober sister to marijuana. Unlike its recreational sibling that’s grown for its psychoactive THC (tetrahydrocannabinol) properties, hemp contains less than 0.3% THC, a value that was the driving force behind the legalization of hemp production in the 2018 Farm Bill. So while you can’t really get high from hemp, you can definitely enjoy its material benefits — which are plenty!
What is Hemp Clothing?
The simple answer is that hemp clothes are garments made from hemp fabric! But the important caveat here is that most hemp clothes on the market today are not made from 100% hemp fabric. They are usually blended with other fibers, like cotton.
At this point, hemp fabric manufacturing is not at the scale or technological level that the manufacturing of cotton (the most popular natural material) is, making 100% hemp clothing more expensive to produce. Also, pure hemp fabric is also known to be quite stiff until a couple dozen washes later, so blending it with a fiber like cotton can make it softer and easier to wear on the offset.
100% hemp fiber content clothing does exist, it’s just rare at this point. Though we do think this will change with more sustainable material investment happening in the textiles industry.
Is Hemp Clothing Comfortable?
It depends! The softness of hemp clothing will vary based on how the fabric was produced and if it is blended with other fibers like cotton or lyocell. Pure hemp clothing can be rougher than cotton, but hemp is known to get softer with every wash.
Also, since hemp is a natural bast fiber that comes from the softer parts of the plant’s stalk or stem, it is softer than the coarser leaf fibers.
Can Hemp Clothing Protect From The Sun?
A lesser known benefit of hemp clothing is that it can reportedly even help shield you from harmful UV rays. According to skin cancer research, a fabric’s UPF (Ultraviolet Protection Factor) value is a number that coincides with the fraction of UV rays it allows to pass through and hit your skin — the higher the UPF number, the better the protection.
Research claims that hemp has a UPF of >50 (according to European standards) due to natural pigments and lignin within the fibers, which act as UV absorbers.
Is Hemp Clothing Sustainable?
There are a lot of benefits to hemp clothing. But don’t just take our word for it, we’ve listed some of hemp’s most impressive sustainable qualities below:
1. Hemp is not resource-intensive
Hemp can be grown under a variety of agricultural and ecological conditions and has a capacity to grow rapidly.
Hemp clothing vs. cotton: With a high yield of 250% more fiber than cotton, hemp requires less land to grow, has no need for harmful pesticides or chemicals, and needs as little as 1/3rd of the water compared to conventional cotton. (Though individual use cases may vary based on the region that each of the crops are grown.)
2. Hemp is a restorative plant
Growing hemp can also help contribute to the maintenance of soil quality, courtesy of its anchored roots which prevent soil erosion and nutrient loss.
In fact, research shows that hemp can be used to restore contaminated soils through ‘phytoremediation’ — a process that has proven successful in the early 90s when industrial hemp was planted in some of the polluted Ukrainian regions near the Chernobyl disaster where much of the land was rendered useless. The experiments showed that hemp helped remove radioactive elements from the soil.
3. Hemp can absorb carbon more than other plants
Hem can act as a carbon sink. According to a Cambridge University researcher, a hectare of hemp can absorb between 8-15 tonnes of CO2, giving hemp plants a vital role in reversing carbon emissions.
