The International Day of Zero Waste, observed on March 30th annually, was established through UN General Assembly Resolution 77/161 and is jointly facilitated by the United Nations Environment Programme (UNEP) and the United Nations Human Settlements Programme (UN-Habitat). The day highlights the importance of waste reduction, sustainable materials management, and responsible consumption and production as part of sustainable development.

This year’s theme and why it matters

This year’s theme is “Towards zero waste in fashion and textiles.” According to the non-profit organization Global Fashion Agenda, 92 million tonnes of textile waste are produced globally each year. (Note that a “tonne” or metric tonne is equal to 2,204.6 lbs., as opposed to a “ton,” a.k.a. short ton, which is equal to 2000 lbs.) In 2018, the U.S. EPA found that nearly 17 million tons of textile waste were generated nationwide, with 11.3 million of those tons going to landfills (3.2 million tons were combusted).  According to the Illinois Materials Management Advisory Committee Report to the General Assembly (2021), 279,188 tons of clothing were disposed of in Illinois landfills in 2018, along with 235,523 tons of “other textiles.” In its 2017 report A new textiles economy: Redesigning fashion’s future, the Ellen MacArthur Foundation stated that between 2000 and 2015, global clothing production doubled while the duration of garment use decreased by 36 percent. So-called “fast fashion,” defined by Merriam-Webster as “an approach to the design, creation, and marketing of clothing fashions that emphasizes making fashion trends quickly and cheaply available to consumers,” tends to involve production of less durable items that wear out quickly, contributing to this trend of high production rates and shorter periods of use.

In a previous ISTC blog post (dated 6/26/24), we pointed out the connection between textile waste, particularly clothing waste, and plastic pollution, given that 60% of material made into clothing into clothing is plastic, including polyester, acrylic, and nylon textiles. The UNEP report Catalysing Science-based Policy Action on Sustainable Consumption and Production: The Value-chain Approach & its Application to Food, Construction and Textiles (2021) indicates the fashion and textile sector account for 9 percent of microplastic pollution reaching the oceans annually.

Further, it is estimated that over 15,000 chemicals are used in textile manufacturing processes, some of which are toxic or prone to persistence in the environment (Roos, et al, 2019). Textile manufacturing also uses lots of water and is responsible for massive greenhouse gas emissions. Given the variety of textiles produced, and with some being natural and others synthetic, it’s hard to characterize the total amount of water used for, and emissions resulting from, all textile production worldwide. Considering a cotton t-shirt as an example, a frequently cited article from the Spring 2014 edition of World Wildlife Magazine claims it takes 713 gallons (2700 liters) of water to produce one cotton t-shirt. Mayer and Birkocak (2024) estimate the textile and apparel industry accounts for approximately 10% of global greenhouse gas emissions.

Suffice it to say, due to the massive amounts of resources involved in the production of textiles, the potential for pollution from the manufacture and use of textiles, and the amount of textile waste filling dwindling landfill space, anything we can do to reduce waste associated with textiles is important.

Ideas for positive action

While the potential negative impacts associated with textiles seem daunting, there are several things that individuals can do to prevent textile waste and manage them more responsibly at their end-of-life. Here are a few suggestions to consider.

  • Resist “fast fashion” by reducing the amount of clothing you buy. Avoid trends and purchase more “timeless” styles that will serve you for years to come. Look for individual pieces (shirts, pants, accessories, etc.) that can be paired with multiple other items in your wardrobe to create more outfits with fewer items. If you want some guidance, check out How to Create Different Outfits with Fewer Items (& Sustainably) from Project CeCe and How to Build a Capsule Wardrobe: Wear Fewer Pieces, Create More Outfits from Closet Cachete. How to Create More Outfit Choices With Fewer Clothes includes examples using men’s fashions.
  • Invest in more durable items. The upfront cost may be higher, but reducing the need to replace worn out items can make that worthwhile in the long run. Check out Good on You’s guide to choosing clothes that last.
  • When possible, buy secondhand clothing from thrift stores, consignment shops, or similar outlets. You might get lucky and find some deeply discounted, high-quality items that wound up at a thrift store precisely because they were made to last! In any event, keeping wearable clothing in use longer conserves the resources invested in their creation. If you have items that are still wearable but no longer wanted, consider donating or consigning them at relevant local charities or shops.
  • Participate in, or host, a clothing swap, in which friends or community members come together to exchange items that are still in good shape but no longer wanted by the original owner. Check out the Wikipedia article on clothing swaps for more information on this phenomenon. For advice on planning your own, see 4 Tips For Throwing A Successful Clothing Swap from Southern Living and How To Host A Clothing Swap Party: Step-By-Step Guide from Almost Zero Waste.
  • Repairing your clothing and textiles, rather than replacing them when seams rip or holes begin, is another strategy to conserve natural and financial resources. If you’re not handy with needle and thread, connect with friends or family who are, or support the local economy by taking items to an alteration shop or shoe repair service in your area. You can also do an Internet search for a local Repair Café, Fixit Clinic, or similar gathering where others might help you fix your items. You might also look for no-sew options using iron-on patches, fabric glue, or shoe glue (Shoe Goo is a popular brand of the latter, available in many hardware or “big box” stores; though typically used to repair soles that are separating from uppers, the Shoe Goo website notes that it can also be used for other repairs, such as fixing holes in backpacks). Marissa Elena’s Simple Ways To Mend Your Clothing Without A Sewing Machine is a good resource with embedded videos for illustration.
  • Wash your clothing less frequently and use cold water when you do. Unless you’ve sweat profusely or been doing a particularly dirty job, your outer garments might be able to be aired out and worn at least one additional time before getting tossed in the laundry basket. Washing less often will reduce wear and tear on your clothing and reduce your chores as a bonus. Check out Real Simple’s guide on how frequently to wash various types of clothing. And Don’t Bother Using Hot Water to Wash Your Laundry from Consumer Reports should set your mind at ease about the efficacy of cold water, which means less energy used during washing.
  • Reuse your textiles for crafts or cleaning rags. Some people enjoy making quilts or rag rugs from fabrics reclaimed from old clothes, or even tote bags or hot pads. See 9 Ways to Make a Rag Rug you’ll Want to Try! for some inspiration. If you’re not crafty, consider repurposing your castoffs into cleaning rags you can launder after use—an option that will also help you reduce your use of disposable items like paper towels. Some textiles are of appropriate size to use as rags as-is (e.g., an old washcloth or cloth diaper), but if you want to cut old shirts or pants down to size, use pinking shears to reduce fraying.
  • Recycle textiles that are not suitable for donation that can’t be repurposed in your own home. Check city, county, or local non-profit websites for “where to recycle it” guides, or do an Internet search to find recycling options near you. If you’re not sure which agency to contact in your area, reach out to the Illinois Recycling Foundation for guidance. Textiles collected for recycling might be turned into industrial rags, insulation or other construction materials, or carpet padding, among other items. Like more traditional recyclables, textiles should be seen as resources that don’t belong in landfills.

If you’re already doing some of the things suggested above, great! If it’s all new to you, don’t try to tackle everything at once. Choose one or two suggestions that fit well with your situation and circumstances and try them out. Talk to friends and family about your successes, and any challenges you encounter. They might help you overcome barriers and you just might inspire them to fight waste too! Don’t focus on trying to be perfect–you’re human, after all. If you try too many new things at once, or get too wrapped up in doing the exact “right thing,” you may become overwhelmed and either never start your new habit, or start and quickly give up. Every small step you take to reduce waste matters. If you’ve read through this whole post, congratulations–you’ve taken the first step toward sustainable behavior by being open to new practices!
