On the surface, recycled polyester seems to present a more sustainable alternative. Produced by recycling existing polyester fabric and PET bottles, recycled polyester consumes around 59% less energy compared to virgin polyester (Rawson, A. et al., 2020). This reduction in energy use can significantly decrease greenhouse gas emissions, a vital step towards mitigating climate change. 

Yet, calling recycled polyester a truly green alternative would be misguided. It is undeniable that recycled polyester is less environmentally damaging than its virgin counterpart, but it still carries a heavy environmental toll. While it mitigates the problem of discarded plastic, it doesn't completely solve the microplastic pollution issue. A study by Plymouth University (2016) found that synthetic garments release hundreds of thousands of microplastic particles during each wash cycle, regardless of whether they are made from virgin or recycled materials.

Instances certainly exist where synthetic fibres are required for the structural integrity or the longevity of a garment. Performance wear and outdoor gear often rely on the durability and moisture-wicking capabilities of synthetics. However, in many cases, natural fibres could effectively replace synthetic ones without compromising on quality or function. 

Cotton, linen, wool, silk, and hemp are all natural fibres that are biodegradable, meaning they break down over time, unlike synthetic fibres that can take hundreds of years to decompose (Earth Pledge, 2007). Moreover, they don't shed microplastics into our waterways, presenting a less harmful alternative to our environment.

As we look towards a more sustainable future, it is vital that we consider not just the end of a product's lifecycle but the entire lifecycle, including production. Natural fibres require less energy to produce and often engage in more sustainable agricultural practices than the creation of synthetic fibres. 

In the pursuit of appearing eco-friendly, some fashion brands have resorted to "greenwashing," promoting recycled synthetics as a sustainable option, despite the availability of more environmentally friendly alternatives. While recycled synthetics are a step in the right direction, they shouldn't overshadow or replace the use of natural fibres where possible. It is crucial that we, as consumers, remain vigilant about these marketing strategies and make informed decisions when purchasing our clothes. 

While recycled polyester presents an improvement over virgin synthetic fibres, it is still far from an environmentally harmless option. At Cloth & Co., we are committed to the mission of producing high-quality, natural fibre products, driving the fashion industry towards a greener, more sustainable future.
