In a new study, researchers have made a promising discovery: a compostable material that can serve as an alternative to plastic. The material is made from a combination of used coffee grounds and spores from Reishi mushrooms that are made into a paste, then 3D printed.
The idea started when Danli Luo, corresponding author of the study and doctoral student of human-centered design and engineering at University of Washington, noticed the amount of coffee grounds that accumulated from making espresso at home.
Luo, along with co-author Junchao Yang and senior author Nadya Peek, explored how coffee grounds could serve as an ideal growing base for the strong mycelial network that precedes mushroom growth. The team set out to explore a way to use up the spent coffee grounds and make them into a strong, lightweight material that would be a more sustainable alternative to plastic.
First, they turned the coffee grounds into a Mycofluid paste by combining them with the spores of Reishi mushrooms, brown rice flower, water and xanthan gum to act as a binder. This created a promising material that would work with a 3D printer.
From there, Luo developed a bespoke printer head to print the paste into more intricate and complex designs that could mimic the versatility of plastic without a need for molds. The researchers made multiple objects using the design, including shipping packing materials that could be a substitute for plastic foam (or Styrofoam), a vase, a small statue and a miniature coffin.
“We’re especially interested in creating systems for people like small businesses owners producing small-batch products — for example, small, delicate glassware that needs resilient packaging to ship,” Luo said. “So we’ve been working on new material recipes that can replace things like Styrofoam with something more sustainable and that can be easily customized for small-scale production.”
After printing, the team kept the objects moist and in a sealed plastic tub for 10 days to allow the mushroom spores to develop into a mycelial skin. Then, they removed the objects and dried them to prevent mushroom development. The team published their method in the journal 3D Printing and Additive Manufacturing.
From the upper left to bottom right: the 3D printer creates a design; three printed pieces of a vase; the partially set vase pieces are put together; the mycelium grows on the coffee paste; the vase grows together; the finished vase holds flowers and water.

According to the authors, their method costs $1,700 for hardware for the experiment, and the 3D printer could hold up one liter of paste at a time. By comparison, they noted that other similar solutions cost more than $7,000. However, they did note that the Mycofluid paste was dependent on uniform coffee grounds, which would limit scaling ability.
Moving forward, the researchers behind the coffee-and-mushroom material also hope to explore other food waste materials that could be developed into paste for 3D printing that may have better scaling opportunity.
“We’re interested in expanding this to other bio-derived materials, such as other forms of food waste,” Luo said. “We want to broadly support this kind of flexible development, not just to provide one solution to this major problem of plastic waste.”
More and more scientists are looking into ways to make use of the estimated 60 million tons of spent coffee grounds that are wasted globally each year. For instance, New Atlas reported that RMIT University researchers found a way to incorporate spent coffee grounds into concrete to make the concrete up to 30% stronger.
Other coffee waste, such as the husks, have also been valuable to a Colombian company called Woodpecker, which has used coffee husks combined with recycled plastic to build low-cost, prefabricated buildings.

There’s something undeniably special about wearing uniquely handcrafted, fair trade jewelry that you can know was made slowly and thoughtfully with care. Equally special is wearing an elevated set of jewelry crafted with recycled materials and sustainable processes.
Whether you’re looking for an investment piece or more affordable pieces, there are options for any budget on this list. The aesthetics of these fair trade and sustainable jewelry brands also vary, so you’ll also be able to discover an ethical brand that matches your unique style.
What is Fair Trade Jewelry?
Fair trade can both be a general term used to describe a brand’s sourcing practices — like direct relationships with artisan cooperatives, wages above local standard rates, and safe working conditions — or a third-party “Fair Trade” verification through an organization like Fair Trade Federation, Fair Trade USA, or World Fair Trade Organization. When a brand doesn’t have a certification, we verify a brand’s practices by their own published information.
In the cases where brands do go the extra mile and get a third-party verification for their fair trade practices, we’ve noted it directly in their entries.

11 Best Fair Trade and Sustainable Jewelry Brands That Shine
It’s time to leave fast fashion in the dust — with one-of-a-kind designs, quality fabrics, and the assurance your dollars are supporting a more responsible fashion industry, these slow fashion brands are sure to win you over.
Before we go any further, though, I think we need to clarify what exactly slow fashion is…
What Do I Mean By “Slow Fashion?”
Slow fashion is about being more mindful and thoughtful about how clothing (and other fashion items) are being produced, how they’re being purchased, and how they’re being used/worn.
Instead of mass-producing trend-driven garments cheaply and quickly, slow fashion production is about creating a piece to last by using high-quality materials, transitional designs (i.e. they migth be contemporary but they’re not super “trendy”), and durable construction.
For individuals, slow fashion purchasing habits means buying less, but better. A slow fashion mindset is all about choosing well — it’s about picking well-made items that are built to last and also selecting pieces that fit your lifestyle and body well, to ensure they’ll not only be durable but will actually be useful for years to come.
Adopting slow fashion in your life, though, doesn’t necessarily have to mean spending money — this concept is also about slowing down to appreciate your clothes and closet. Slow fashion can mean wearing what you have as much as possible, mending and repairing worn clothing, or upcycling an even sewing your own clothes.
For more, read “What is Slow Fashion, Really?”
While slow fashion is a term that’s often used quite generally, it’s important to note that there are fast fashion brands that might have some organic or recycled clothing. Those did not make the list!
Slow fashion companies to me — and the criteria used to select brands for this guide — are brands that produce in smaller batches, make most of their pieces by hand, craft each piece with attention to detail and quality, and ideally, partner with skilled artisans, sewers, and craftspeople (who are of course fairly paid).
Now without further ado, here are our picks for…
My Top Picks for Slow Fashion Brands
To be clear: you do not need to purchase from slow fashion brands to participate in slow fashion. However, when the time comes that you want to add a new piece to your wardrobe, you probably want your dollars to go towards supporting responsible brands that are doing things better; that are producing with quality and intention.
You want to invest in pieces for the long-haul — and pieces that have a positive impact. And these slow fashion brands will help you do just that.
