The importance of textile recycling continues to be recognized, with an estimated 100 billion garments being produced annually worldwide. As textile production increases, so does the generation of textile waste. Today in Europe, more than 15 kilograms of textile waste is generated per person, posing various negative consequences for people and the environment. Consumers’ discarded clothes and home textiles account for around 85% of the total waste, making them the largest source of textile waste. The generation of waste has necessitated the growth of the textile recycling industry. This significant transformation could create a large and sustainable textile industry that makes value out of waste.
What is Textile recycling?
Textile recycling is the process whereby textile waste like discarded clothing and other textiles are recovered for reuse. It is an essential aspect of the textile industry that aims to reduce landfills inside and outside Europe. The textile recycling process involves donation collection, sorting, and processing textiles and transportation to end users of recovered materials. Considering the tons of waste generated, textile recycling is a significant challenge to be addressed as we strive to move closer to a zero landfill society.
It takes up to a few weeks or even several years for natural fibers to decompose once in landfills. These fibers negatively affect the atmosphere by releasing CO2 and methane gas. Further, synthetic fibers do not deteriorate, releasing toxic substances into groundwater and nearby soil. As the textile recycling industry grows, various environmental benefits will be seen. They include:
- Less energy and water consumption
- Reduced demand for dyes
- No pollution
- Decreased landfill space requirements. Landfills and incineration are the primary end destination of textile waste. But textile recycling will reduce the quantity of waste in the environment.
Addressing the waste problem
Various approaches can help address the waste problem. For example, fashion companies can focus on slow fashion trends because they generate considerable waste. Designing products for increased circularity and extending product lifetime can also help solve the waste problem. Fiber-to-fiber recycling is one of the most sustainable scalable levers available. It involves using textile waste to create new fibers, which are then used to make textile products like new clothes. Fiber-to-fiber recycling technologies require strict input requirements; for example, straight leg jeans and pants must have their zippers and buttons removed before processing.
Other technologies that have been established include the mechanical recycling of pure cotton. Chemical recycling of polyester is yet to be established but is on the brink of commercialization. Once these technologies are mature, about 70% of textile waste could be fiber-fiber recycled. But before them, several barriers to scale need to be overcome. Today, less than one percent of textile is fiber-to-fiber recycled.
Sources of textile for recycling
The two primary sources of textiles for recycling include:
