Sustainable clothing is gaining traction to combat the world of fast fashion. The fashion industry is responsible for almost 10% of global emissions and is on pace to double by 2030. Americans toss an estimated 11.3 million tons of textile waste, or 2,150 pieces of clothing per second, into landfills every year. Studies have found that on average, clothes are discarded after only 7-10 uses.

Fashion culture encourages us to quickly move on to the latest styles and to forever keep cycling through a new wardrobe. And I’m not immune. I love shopping and getting new things, and have succumbed to retail therapy more than I’d like to admit. Join me in slowing down purchasing and move toward adding sustainable clothing to our closets, while keeping old, worn items out of the landfill.

For an in depth look at fashion waste, I recommend this Bloomberg article.

How to minimize your fashion environmental impact

Buy less

The first step to reducing your style footprint is to assess whether a new item is really needed. I totally get retail therapy, but when you take time to stop and really evaluate, you probably really don’t need another pair of shoes or a new bag.

We are probably all guilty of buying clothes simply because it was too good of a deal to pass up. Or maybe we bought something with the intention of fitting into it soon, only to have the item sit and gather dust in the closet. Instead, be more selective in your purchases. I think there’s value in Marie Kondo-ing shopping: Does this item bring you joy? OK, maybe joy is a little much, but do you like how you feel in the clothing? And not only comfort, does it affect your confidence? Do you love it? Do you love it enough to be really disappointed if they didn’t have any in your size? If there’s any waffling or doubt at all, walk away.

Consider renting clothing that is only needed for a short time. Everyone knows you can rent a tuxedo, but did you know you can rent all types of apparel, too? For formal dresses and gowns, check bridal shops, or search for local businesses that rent dresses. You can also rent formal clothing, as well as maternity clothes, outfits for vacation, or just regular clothes from Rent the Runway.

Make smart clothing purchases

Go for quality over quantity. I’ve always been a firm believer in this approach. I would rather spend more upfront for a well-made article of clothing than one cheaply-made from poor quality materials. You know the ones that morph into a non-human shape, shrink, pill, or just look plain terrible after only a few times through the laundry.

Avoid shopping at notoriously bad fast fashion stores like Shein or Forever 21. I sat my 14-year old daughter down and explained to her why we won’t be buying clothes from these sweatshops, and she’s on board with looking for sustainable clothing.

Shop thrift and vintage clothing

Vintage and thrift clothing extend garment lifecycles, reducing waste and the demand for new production, which in turn lowers resource use, energy consumption, and environmental pollution, making them very eco-friendly choices. And being less expensive than buying new pieces is an added bonus.

Try shopping in local second-hand stores or online at thredUP or Poshmark.

Avoid synthetic fibers

Almost 70% of today’s clothing is composed of synthetic materials, the majority of that being polyester. Other common synthetic fabrics include spandex, nylon, and acrylic. These materials are all derived from fossil fuels, and their production uses more energy and produces more emissions than the processing of natural fibers.

In general, synthetic fibers require more harsh and potentially toxic chemicals in the production than natural fibers.

Because they contain plastic, synthetic materials are not biodegradable and can take centuries to decompose, leaching chemicals into the soil and water in the process.

Synthetic fabrics significantly contribute to the world’s microplastic problem: it is estimated that up to 35% of microplastics in the ocean and 71% of microplastics in rivers come from synthetic clothing. In your own home, textile microplastics compose 33% of dust floating around. Read more about plastics here.

Besides environmental impacts, synthetic fabric can stink in other ways. Literally. Polyester attracts more oil from your skin, requiring more frequent laundering. In fact, one study showed that polyester fibers can absorb odor-causing compounds and not wash out completely, leading to a buildup of odors over time. That explains why I’ve noticed some of my workout wear still smells funky even after washing—glad it’s not just me!

Instead of synthetic fibers, select clothing made from natural, biodegradable sustainably sourced materials, such as organic cotton, hemp, linen, bamboo, wool, silk, cashmere, or Tencel (aka Lyocell and Modal). Clothing made from recycled materials is generally a good option.

Activewear can be especially tough to find in natural fibers. Tencel modal or lyocell are great options. There are quite a few sustainable companies with sustainable yoga clothing and other workout wear. I am a big Athleta fan, or more accurately, an addict. Many of their products are made with natural fibers, and these can by found by filtering fabric material. Other great options include Girlfriend Collective, Vuori, Patagonia, and Nordstrom brand Zella.

Take a deep dive into natural vs synthetic fabrics, as well as environmental considerations for each type of common fabric here.

Properly care for your sustainable clothing

• Read care labels for clothing and follow care instructions to prolong the quality and life of your clothing.
• Don’t automatically toss worn clothing in the hamper. Consider how long the item was worn (synthetic fabrics needs to washed more frequently) and if not visibly dirty or stained and passes the old sniff test, maybe it can stand another wear.
• Find a good tailor or seamstress (unless you know how to sew) to repair your clothing to give it more life.
• Check out these additional clothing care tips from H&M and Nordstrom to help make your clothing last longer.

Accessories

What to do with old belts

Donate or check out some other practical reuse ideas.

No matter the material, belts are most likely not going to be recyclable. The metal buckle can be taken to a scrap metal recycler.

Watch recycling

Send your old watches to We Recycle Old Watches. They refurbish watches when possible, or take them apart and recycle the separate parts or upcycle them. Recycle smart watches at Best Buy or other places that take e-waste.

Clothing donation options

For many, the default method of getting rid of unwanted clothing is donation. While this is good in theory, whether your clothes actually are given to someone in need or sold in a thrift store is a question you need to ask. Much of what is donated is actually thrown away or shipped overseas.

The best choice is to start with someone you know. Maybe you have a friend or family member that could use some of your unwanted clothing.

Next, try a local Buy Nothing or Freecycle group. I have come to really like this option for donating items because I know they’re going to actual people that want them rather than some mystery destination.

Selling unwanted clothing in good condition is a good option. Try a local consignment store or a website such as thredUP or Poshmark, or try to find a local clothing swap.

Textile recycling for non-donatable items

Only 13% of clothing gets recycled and the rest ends up in the landfill or is incinerated.

It can be really difficult to find local drop-offs for textile recycling. Some places that you can try include:

• H&M accepts old clothing in stores and in return you will receive a coupon for future purchases. However, they have come under fire for allegedly not actually recycling the materials they collect.
• Savers. You can label your donation as ‘scraps’ and they will recycle them.
• Goodwill stores may recycle unusable items; check with a store near you.
• Helpsy is a Certified B Corp that operates clothing donation & recycling bins the northeastern U.S.

Most likely, you will have to use an online recycling program. The benefit to these is that many are through specific brands and retailers and you can earn discounts on future purchases.

Terracycle has a Zero Waste Fabric and Clothing box. However, this is not cheap…prices start at $136. They do offer some free programs, the best of which is their Carter’s + Terracycle program, which accepts any brand of baby’s and children’s clothing.

• Recycle worn out denim with Zappos for Good + Blue Jeans Go Green program.
• Retold Recycling has options for a one-time bag purchase starting at $14.50 or an annual subscription; you fill up the bag with your unwanted textiles and send it to them with the prepaid shipping label. They sort through your things and depending on the condition, send them to thrift stores, donation centers, recyclers, resellers and up-cyclers.
• Supercircle works with many individual companies on recycling solutions. One such program is Thousand Fell’s Trade In by TF, which accepts any type of textiles as well as shoes for recycling. Create an account and they will send you a pre-paid shipping label to ship your well-worn goods. Once received, they give you points towards future purchases.

Brand-specific clothing recycling

Check whether the brand of clothing you own has a recycling program. The benefit to these is that many specific brands and retailers will reward you with points or discounts on future purchases. The downside is that most will only accept their own products.

• Patagonia. Send in your unwanted things, and if it is in good condition they can resell, you can receive up to 50% of the resale price through credit. If not sellable, Patagonia will recycle your gear so it stays out of the landfill.
• North Face. Recycle apparel and footwear at their stores and outlets and earn a $10 reward toward your next purchase of $100 or more.
• H&M accepts old clothing in stores and in return you will receive a coupon for future purchases. Depending on the clothing condition, it will be used as secondhand clothing, repurposed into other products, or recycled by being shredded into textile fibers and used to make other materials.
• For Days. Order a Take Back Bag to fill with old clothes (any brand/condition) and earn 20% off your next purchase of their sustainably-sourced clothing.
• Marine Layer. Their Re-Spun t-shirt recycling program gives you a $5 credit per tee.
• Madewell drop off any brand of jeans in exchange for $20 off a new pair.
• Levi’s SecondHand trade-in program allows you to bring in old denim and receive a gift card in return.
• American Eagle. Donate old jeans for 20% off a new pair.
• PacSun. Donate old jeans for $10 off a new pair.
• Check BlueJeansGoGreen for more retailers offering trade-in discounts; some are for specific date ranges only.

Composting clothing

The last option (which I have yet to try) is composting. This can be done only if items are made from 100% natural fibers, such as cotton, wool, silk, cashmere, linen, or hemp. Remove decorations, lace, buttons, zippers, elastic, and labels that will not break down. Cut the fabric into small pieces for faster breakdown.
