Is stretch denim bad for the environment?
The synthetic materials used in the production of stretch garments, such as elastane (Spandex, Lycra etc) as well as polyester and other synthetic blends, have significant negative environmental impacts. These materials are derived from fossil fuels, which depletes finite resources and contributes to environmental strain. The production process of these fibers releases harmful gases into the atmosphere, further exacerbating environmental issues. In general, it is estimated that these synthetic materials can persist in the environment for hundreds of years or even longer. Additionally, the washing of garments made from these synthetic fabrics poses a threat. Microfibers, minuscule pieces of plastic, are released into water streams during washing, causing harm to marine life and ecosystems. The recycling of synthetic blended fabrics is also challenging due to the limited technologies available in textile recycling plants. As a result, garments made from these materials often end up in landfills where they contribute to the emission of methane gases as plastic-based fabrics break down. Alternatively, unsold stock may be incinerated, releasing toxic fumes. In summary, the use of synthetic materials in stretch garments presents multiple environmental concerns, including resource depletion, greenhouse gas emissions, microfiber pollution, and limited recycling options. Addressing these issues is crucial for the sustainable future of the fashion industry.
