Textile Waste is a Growing Problem
As the fast fashion industry continues to churn out new clothing designs at an unprecedented rate, the amount of textile waste sent to landfills has skyrocketed in recent decades. It is estimated that over 85% of all textiles produced worldwide end up in landfills or incinerators within one year of being manufactured. This surge in textile waste presents major environmental challenges as clothing is made from both natural and synthetic materials that do not biodegrade easily. When textiles enter landfills or are incinerated, they release greenhouse gases and microplastics that pollute the air and waterways. Recycling textiles provides an alternative solution for discarded fabrics and helps divert waste from overflowing landfills.
Benefits of Recycled Textiles
There are numerous environmental and economic benefits that arise from recycling old textiles instead of trashing them. Reusing fabrics significantly reduces demand for virgin materials, thereby lowering the impacts of resource extraction, chemical processing, water usage and carbon emissions associated with textile production. Recycled fibers require less energy to produce compared to manufacturing fibers from raw materials. Collecting pre- and post-consumer textiles also creates jobs in the recycling industry, from sorting facilities to fiber reprocessing plants. Charitable organizations are able to reuse quality donated clothes through thrift stores, supporting those in need while keeping usable items out of landfills. Revenue from recycling programs provides funding for further environmental initiatives as well.
Common Recycled Textile Options
There are a few main ways that old fabrics can be processed for recycling:
- Downcycling - Worn or damaged fabrics are shredded or torn down into wiping rags, insulation stuffing or other low-grade products. This extends the life cycle of materials.
- Fiber-to-fiber recycling - High quality used clothes are sorted by fiber type (cotton, polyester, nylon, etc.) and re-spun into new fabrics identical to virgin materials. This allows recycled fibers to be reintroduced into apparel and home textile supply chains.
- Thermal recycling - Synthetic fabrics that cannot be mechanically recycled, such as some polyester blends, are incinerated to generate electricity through waste-to-energy plants. This diverts materials from landfills.
- Chemical recycling - Experimental technologies are researching how to depolymerize used plastics like polyester back into their original monomers through chemical processes, allowing remanufacturing into new plastics or fibers.
Extended Producer Responsibility Programs
Many areas are establishing extended producer responsibility (EPR) systems for managing post-consumer textiles, where producers are made financially responsible for recycling products at end of life. Such systems incentivize brands to design for disassembly, use recycled content in manufacturing and promote textile recycling programs to consumers. Large EPR programs currently operate in countries like Germany, Belgium and Norway. Several US states including Maine, Oregon and New York are pursuing textile EPR policies to help increase recycling rates from current levels under 15% nationwide. When financially liable for waste management costs, companies invest in take-back and sorting infrastructure needed for circular materials flows.
Consumer-Focused Recycling Options
Various convenient options now exist for consumers to participate in textile recycling:
- Curbside collection - A growing number of municipal recycling programs accept commingled textiles with other recyclables for curbside pickup. Drop-off bins may also be located at transfer stations or recycling centers.
- Mail-back recycling bags - National chains like H&M, Gap and I:CO offer pre-paid mailer bags for sending any brand of used clothing by mail in recycled collections.
- Donation bins - Purple-tagged bins operated by Goodwill, Salvation Army and other charities accept wearable clothing donations year-round at convenient locations.
- Thrift and consignment stores - Beyond donating, consumers support the circular economy by purchasing pre-owned clothing and home goods from brick-and-mortar thrift shops.
- Business take-back programs - Some office supply stores like Staples will accept small quantities of used textiles through their recycling drop-offs.
With sufficient education around textile recycling options now widely available, individuals play an active role in reducing fabric waste through donating or collecting items no longer needed. When the majority of post-consumer clothes can be repurposed or recycled, landfill loads are significantly reduced.
Future Outlook for Textile Recycling Growth
As sustainability becomes an increasing focus for governments, producers and consumers alike, the market for recycled textile materials is projected to experience exponential growth in coming decades. Advances in sorting and processing technologies will drive fiber reclamation rates higher. Continued expansion of EPR laws and voluntary brand take-back schemes will broaden recycling infrastructure and collection rates worldwide. The development of innovative recycling platforms like chemical breakdown of synthetic fabrics hints at the technical potential for achieving near-100% rates for textile resource recovery overall. With dedicated efforts across supply chain and disposal system stakeholders, the circular economy model of recycling old clothes into new promises an encouraging future for both environment and industry alike.
