But then neither is polyester or nylon. Nylon manufacture creates nitrous oxide, a greenhouse gas 310 times more potent than carbon dioxide. Polyester is a man-made product. Kalliala and Nousiainen (1999) develop an environmental index model based on life-cycle assessment to determine total environmental impact, including energy in laundering, of a range of fabrics. Different fabrics have different impacts, depending on what they’re made of: Nylon and polyester Made from petrochemicals, these synthetics are non-biodegradable as well, so they are inherently unsustainable on two counts. In short, polyester is just average when it comes to environmental impacts during its production, and it depends a lot on how it’s made, rather than the polyester itself. Textile bags need to be reused more times to lower their environmental production cost. Read more about the environmental consequences of polyester production at peacefuldumpling.com .
