Can coffee grounds be reused? What can I reuse coffee grounds for? Is it possible to have fabric made with coffee grounds? What if you could make new textiles from your waste products? The answer to all these questions are a resounding yes. First you drink it and then you wear it. Innovative textile solutions means that you can have clothes made from food.
The Coffee Drinking Habit
Drinking coffee is an important part of our international culture and the daily coffee consumption habit is creating a huge amount of spent coffee grounds. Coffee was first discovered in Ethiopia in the seventh century and by the eleventh century it had become a beverage. During the fifteenth century the habit of drinking coffee began to spread through Europe.
Twenty five billion kilograms of spent coffee grounds are generated each year, of which only 4% is properly recycled. The other 96% becomes trash, which emits methane (CH4) and carbon dioxide (CO2), the two main greenhouse gasses.
Coffee today is not only a very popular drink, but also a way of life. It is not only available as a beverage, but also in the clothes that we wear through fabric made with coffee grounds.
Why use Coffee for Clothes Made from Food?
Coffee grounds have a unique deodorizing function as coffee has a natural ability to block odors. When roasting coffee beans, they swell and the space inside the bean expands. During brewing, hot water removes any materials that are blocking the spaces.
Coffee fiber fabrics are perfect for sportswear and performance clothing as it eliminates odors.
Coalatree, the eco-minded company, is producing hoodies and joggers made from recycled coffee grounds.
When used coffee grounds end up in landfill, it emits methane, a greenhouse gas that is 30 times more potent than carbon dioxide (CO2) Two products that are harmful to the environment, namely coffee waste and plastic water bottles, are used for innovative textile solutions and to produce fabric made with coffee grounds.
So if you have been wondering can coffee grounds be reused, let’s have a look at some of the companies that are using spent coffee grounds to produce fabric made with coffee grounds.
1. Singtex and S.Café Technology
The Taiwanese textile company Singtex, founded by Jason Cheng, produce a variety of coffee related products, including S.Café coffee yarn and coffee fabrics. After four years of research, S.Café was launched in 2009. They have partnered with local coffee shops and collect their used coffee grounds, thereby using a sustainable route for their raw material.
S.Café is an eco friendly yarn made from coffee grounds. S.Café technology has many renewable features. It recycles spent coffee grounds for fabric yarn. A high concentration of essential coffee oil is extracted through the patented manufacturing process. This oil can be reused in textiles and cosmetics.
The raw material is a combination of coffee and recycled polyester. The basic procedure to obtain the green fiber, which is patented, is to mix the coffee residue with recycled plastic bottle fibers and re polymerize it, before spinning into a coffee yarn. S.Café yarn contains 5% upcycled coffee grounds and 95% recycled PET plastic bottles.
S.Café Coffee Products
Showing how can coffee grounds be reused, several products incorporate the S.Café technology:
- P4Dry is a new fabric printing technology.
- Another S.Café technology is ICE Café, which cools the body temperature down by 1 to 2 degrees Celsius, thereby making you cooler and more comfortable during workouts.
- S.Café AIRNEST is a sustainable bio-foam made of coffee oil and coffee grounds that can replace the petrochemical derived polyurethane PU) foam. It is very versatile and can be used in shoes, home textiles, sports gloves and fabrics.
- Sefia is a 36% bio-based material that combines S.Café yarn with cellulose filaments derived from biodegradable wood pulp. The resulting fabric has excellent drape, high tenacity and stability, is anti-pilling and has all the great benefits of S.Café coffee fibers.
- eco2sy multi layer insulation technology is crested from recycled plastic bottles and used coffee grounds. It is used for jackets and each jacket prevents twelve plastic bottles and three cups of spent coffee grounds from going to landfill.
- AEx membrane is an air exchange technology that is applied on fabric. It is a foam coating technique that blocks 96% to 98% of wind, with the remaining air circulating within the fabric. It greatly enhances the transmission of moisture vapor, while reducing the build-up of heat stress. Through evaporation and convection, the body loses heat and the wind chill factor makes us feel colder than the actual air temperature. By reducing the wind chill with a windproof layer, the body is kept warm and comfortable.
- S.Café Mylithe is created by applying ATY texturing techniques, which is an “air texture” method, to give the fabric a feel like cotton, while still maintaining the original properties.
- S.Café co-brand with American Eagle Outfitters to make Cafe Jeans, denim made with recycled coffee grounds.
- Another Singtex S.Café invention, Airmem, is a special waterproofing membrane made of coffee oil. It contains 25% coffee oil that was extracted from spent coffee grounds and is a more sustainable alternative to petroleum based materials.
Advantages of AIRMEM:
- The microporous membrane technology is windproof, blocking wind while also keeping a soft touch to your skin.
- The ability to control odors is double that of normal membranes.
- AIRMEM is water resistant, thus keeping your body dry.
- It is oil repellent
- The membrane is breathable and provides excellent moisture vapor permeability to keep the wearer dry and warm.
- It is extremely thin, light and flexible and the performance is much better than other PU and PVC materials.
- The eco friendly bio material is made from spent coffee grounds.
These innovative textile solutions are used in ski suits, jackets, sports coats, gloves, hats and outdoor gear, as it also has excellent moisture permeability. AIRMEM received USDA bio-based product certification and 2015 ISPO Award selection.
Singtex patented technology include:
- Special eco friendly yarn technology
- technology for extrusion, stain resistance and absorption
- Technology for laminate and water based coatings
- Bio-material modification technology

Brands that are using Singtex and S.Café fabrics to produce clothes made from food, include Patagonia, The North Face, Timberland and American Eagles Denim. Sustainable yoga and active wear company Rumi, is using it and also smaller niche brands like Ecoalf, Sundried and Five12 Apparel.
2. Cchilu and XpreSole
Cchilu (pronounced Chee-Loo) is a Japanese footwear brand that has developed a green technology called XpreSole, to make shoes from spent coffee grounds (SCGs). Every major component in the shoe is made from coffee grounds.
Wilson Hsu founded Cchilu in 2011. With XpreSole he is using coffee ground as the key component in footwear to make water repellent shoes out of discarded coffee grounds. Five cups of recycled coffee grounds makes one pair of XpreSole shoes. So far XpreSoles has made about 40,000 pairs. This means that 200,000 cups of waste coffee has been upcycled, thus reducing greenhouse gasses and their carbon footprint.
They have developed a formula that mixes and melts coffee grounds into a special compound that is ideal for the uppers and soles of shoes. Using innovative textiles solutions, they are turning waste into footwear materials by recycling millions of tons of spent coffee grounds. Spent coffee grounds from big coffee vendors like Starbucks is taken and recycled.
The technology uses low temperature and high pressure and energy saving processes to combine coffee grounds onto the surface of the yarn. This changes the characteristics of the filament.
The patented process for the fabric made with coffee grounds, includes:
- collecting the spent coffee grounds,
- drying, grinding, sifting and
- making pellets through a proprietary process to create master batches that is sent for manufacturing.
- Used coffee grounds are melted and mixed with recycled plastic bottles.
- This is turned into a yarn that is woven into the upper and the insole, and the out soles also use coffee.
Centralized resources in Taiwan are used to make the master batches, which is also exported. Cchilu make their own range of footwear, called Cody, where the master batches are compounded with other materials.
By using the coffee fabric, the amount of petroleum based materials are reduced by 30%.
- Upper: coffee yarn is mixed with RPET yarn from recycled plastic bottles and high quality canvas.
- Insole: lining is made with a mix of coffee yarn and RPET recycled plastic bottles. Foam is a special XpreSole yarn sole compound made with spent coffee grounds and polyurethane.
- Outer sole: foam is a special XpreSole compound containing spent coffee grounds and ultra lightweight EVA which has a high resilience and great grip.
The Cody sneaker is primarily made from coffee grounds and recycled plastic bottles and Cchilu also makes socks from coffee yarn.
Waterproof sneakers from RENS is combining fabric made with coffee grounds, with recycled plastic waste. The first Rens sneakers made from coffee was launched in the middle of 2019. Each pair uses 300 grams of coffee grounds and 6 plastic bottles to make sneakers that weigh 460 grams.
Rens was started by two entrepreneurs from Helsinki.
Making Rens sneakers start with infusing coffee grounds into plastic pellets and spinning the mixture into a polymer yarn. The yarn is then knitted on a waterproof nano-layer membrane. The natural anti-bacterial qualities of coffee prevents shoes from smelling.
It is easy to clean coffee sneakers by using a clean cloth and standard non-solvent based detergent to wipe away any dirt and grime.
Properties and Benefits of Coffee Fabrics
Fabric made with coffee grounds have many benefits:
- It provides excellent odor control. The coffee grounds, which are embedded within S.Café yarns, absorbs odors.
- Eco friendly
- Has fast drying benefits. S.Café technology accelerates the drying of the fabric by spreading the moisture across the surface area of S.Café garments. By pulling moisture away from the skin, the wearer feels cooler during any activity and thus also more comfortable.
- UV protection: little microscopic holes within the yarn is filled by coffee grounds, which forms a shield that is long-lasting and free of chemicals. It prevents ultra violet rays from coming into contact with the skin.
- Made from recycled materials.
- Sustainable technology is used.
The eco-minded company Coalatree, is using recycled coffee grounds to produce joggers and hoodies, as well as denims.
Features and Benefits of Coffee Shoes
- Coffee is naturally anti-odor, so the shoes do not smell as the microscopic holes in coffee yarn traps odors.
- Water repellent through a coated nano graded polymer layer, ensuring feet and socks stay dry.
- Dirt proof with a coated nano layer prevents dirt and stains
- Moisture wicking
- UV protection – coffee yarn has microscopic holes that reflect UV rays.
- Comfortable and flexible with a good grip. Round shaped grip to prevent slipping.
- Dries quickly
- ultra light weight with a barefoot light feel
- sustainably made
- Vegan friendly
The sneakers are versatile and suitable for leisure, urban, travel, outdoor and rainy day use.

Fascinating article. I am from Ethiopia, the origin of coffee, and many coffee drinkers. I am myself a coffee drinker. You can imagine how much waste of coffee we have in the country. I am interested to know more about how to make tiles with it. Please share more information on this subject with me.
Using waste coffee grounds to make tiles, is in the infancy stages of development. I will share more information as and when it becomes available.
I am looking for sustainable fabrics and am really interesting in coffee fabric I find on your pages. It’s really nice background could be for my research, but I can’t find where to buy and how it looks. And I don’t know if that fabric have an name or just call coffee fabric. I would very appreciate if you can unscrew in my questions. And I would like to know if any possibility to buy from here?
Coffee fabric and the associated technologies are still in the early stages of development into production on a large scale basis. You can contact Singtex, as discussed in the post, to find the latest developments, and whether they would be able to supply you with any of their materials.
I hope this helps you, but please do let me know if you need additional information.
I didn’t know coffee grounds can be harmful when in landfills with that methane release, and here I was thinking that plant-based things are easily decomposable. So glad that we can reuse them as fabrics and man, Pantagonia and North face are two of my favourite brands too! Never knew they are environmentally conscious, makes me proud 😀
Oh yes, Patagonia and North Face are both very sustainable brands and always incorporate innovative textile solutions in their garments.
We really do witness something wonderful every day. Not in My wildest dreams would I have thought that possible. But I appreciate the awareness. The shoes look very trendy as well. I love drinking coffee and I appreciate the background a bout coffee. I would really like some food clothes.
When you think about what can I reuse coffee grounds for, then fabric made with coffee grounds might not be the first thing that comes to mind. The shoes are indeed trendy and also waterproof, with the bonus that they won’t smell either.
This is interesting, I had no idea that the fabric can be made from the coffee ground. I have been using it for deodorizing my fridge and as a scrub for my skin. That is awesome that we can use the fiber for sportswear. I always feel bad when I dump coffee. I definite have to check the footwear out. That will be perfect for my everyday use. Thanks for sharing these companies with is!
Oh great to hear that you have been using spent coffee grounds to deodorize your fridge and also as a skin scrub. You could also use it as a fertilizer for your plants. It is indeed awesome to see what can coffee ground be reused for.
Hi, this was really cool to read about. I didn’t even think about coffee being reusable especially for fabric. Given that there are several fabrics made from natural fibers, I can’t believe it never crossed my mind, especially since I’m so interested in cosplay and whatnot. I personally don’t drink coffee so perhaps that was why it never came to mind. I’m sure my boyfriend wouldn’t mind having coffee shoes. The smell of coffee is quite pleasant, but the taste not so much. I’m not a fan of it, but I did really like this alternative method for using coffee.
When one looks at what can coffee grounds be reused for, it has many amazing uses, with fabric made with coffee grounds, as one of the innovative textile solutions to recycle food waste and also recycle plastic bottles.
This is so great, I wouldn’t have ever think in my heart that this was possible, all my years I have never heard even by chance that clothes are made out of coffee grounds, the most intriguing part of it is that it can absorb odour or odor, this is indeed a super discovery by whosoever made found this creative product.
Coffee is indeed so rich.
thank you for expanding my knowledge.
It is indeed great that fabric made with coffee grounds is now possible and if anybody is still wondering can coffee grounds be reused, it certainly has many applications.
Thanks for a very interesting article! I am a coffee drinker, but keeping it at 1-2 cups daily, everyday. I never knew that coffee was discovered in Africa! Isn’t Africa one of the least producers of coffee now?
I am also hearing for the first time about fabric made from coffee grounds! Great idea to overcome odours. And I am sure very few, if any, people exhibit an allergic reaction to the clothing, as opposed to other natural materials.
But, isn’t the overwhelming majority of coffee consumed in the world not instant coffee, as opposed to coffee grounds? Or do I have a skewed view of the world? 😁
Thank for you comments. Instant coffee might be consumed at home, but not when you go to a café, coffee shop or restaurant, and that is where most coffee grounds come from. Although Brazil is the largest producer of coffee beans, African countries like Ethiopia and Uganda are still very large coffee producers, so a lot of coffee still comes from Africa.
I really enjoyed reading your post, it has opened my eyes to something i had never thought possible. The only point you made that i knew about was coffee as a fertilizer. We all need to do our bit to save the planet from the mass destruction that us humans have caused. I’m very interested in purchasing clothes and shoes made from coffee grounds and plastic bottles. I’m certain many others will feel the same way.
To use spent coffee grounds as a fertilizer is indeed great and I have very successfully used it for an ant problem that I had. Shoes and clothes made from food waste is an awesome way to recycle products and apart from not having smelly shoes, it benefits the planet at the same time.
It’s always good for me to find more information to read about more ways to use different materials to make our world better, and this time is about coffee grounds. I know coffee grounds make great for use it a fertilizers, so I was glad some people are using it to make fabric and shoes, after reading your article it’s clear using coffee grounds to make shoes is a great way with many benefits. I will check for more things made using coffee grounds.
It is great that there are many ways for spent coffee grounds to be recycled and reused. With innovative textile solutions, fabric made with coffee grounds is another awesome way to have shoes and clothes made from food waste.
Hey, it’s been a good time going through this and I want to say thank you for this. This article doesn’t only state the importance of coffee grounds but has always enlighten me more about recycling and also shown that coffee grounds in the production of fabrics is really comfortable. Thanks
It is indeed awesome what can I reuse coffee grounds for, and that includes fabric made with coffee grounds.
