H&M ditches plastic bottles for clothes, embraces recycled clothing in circular solution

H&M is making a major shift in its sustainability efforts, moving away from recycled plastic bottles for polyester and towards a more circular solution: recycling old clothes. The fashion giant has singed $600 million deal for textile-to-textile recycling technology. This decision comes despite the brand's previous reliance on recycled-bottle polyester and its significant investment in that area.

For years, fashion companies have touted recycled-bottle polyester as an eco-friendly alternative to virgin materials. However, a hidden truth is emerging.  While using recycled plastic bottles for clothing seemed like a good idea initially, it turns out there are downsides. Using plastic bottles for clothes takes them out of the beverage recycling loop, potentially harming plastic bottle recycling efforts. Also, transforming bottles into polyester requires significant energy. Regulators are even starting to frown upon this practice.

Recycling old clothes offers circular solution

H&M's new approach focuses on recycling polyester from pre-worn clothing and fabric scraps. This method keeps textiles in use for longer and reduces the need for virgin polyester, a material derived from fossil fuels. The company has invested $600 million in Syre, a Swedish startup developing this technology. Syre's technology recycles polyester directly from old clothes, creating a closed-loop system within the fashion industry

In fact, benefits of textile-to-textile recycling are many. It reduces reliance on virgin materials with less dependence on petroleum-based polyester production. Keeps clothing out of landfills and extends the lifespan of existing materials. Moreover, it has potential for large-scale adoption. Syre aims to process millions of tons of used textiles annually.

H&M's move reflects a growing trend in the fashion industry. Other brands like Zara and Puma are also exploring textile-to-textile recycling.  Legislation like the EU's Extended Producer Responsibility is also pushing brands to find ways to reduce the environmental impact of their products throughout their lifecycle.

Despite the promise of textile-to-textile recycling, challenges remain.  Microplastic pollution from synthetic clothing like polyester is a major concern.  These tiny plastic fibers pollute waterways and pose environmental threats. The industry needs to find ways to reduce fiber shedding and develop better filtration systems for washing machines. Developments in enzyme-based recycling and microfibre filtration offer hope for reducing plastic pollution from clothing. Industry consortiums like the 2030 Microfibre Consortium are working on solutions for minimizing plastic shedding.

H&M's move signals a turning point in the fashion industry's pursuit of sustainability.  While challenges remain, the focus on circular textile recycling offers a promising path towards a greener future for fashion.
