Compostability of Coreva denim confirmed
In a new partnership between Italian denim mill Candiani and Quinto Sapore, an innovative farming project based in Umbria, Italy, offcuts of Coreva denim fabrics were composted and then used to fertilise organic tomato plants. Once harvested, the tomatoes were turned into a tomato sauce, proving once again the non-toxic nature of the company’s natural stretch denim fabrics.

Biodegradability is presented as a growing trend by WGSN, a trend forecasting and consumer insight agency based in London. “While the fashion industry continues to make progress in moving to a circular model, starting the journey to recycle more of the garments it creates still only accounts for around 1% of clothing, so it will be essential to enable waste to safely biodegrade in natural environments,” it stated in its 2024 WGSN Insider report.

With more than 2 billion pairs of jeans manufactured globally every year, a diverse array of solutions is needed to reduce the mountains of apparel waste, and Candiani Denim believes its natural rubber-based stretch yarn Coreva is a viable option.

Italian innovation and testing laboratory Innovhub tested the denim fabrics to assess their degree of disintegration (ISO 16929-2019) and evaluate the ecotoxic effect of the compost to higher plants (EN 13432:2000 Annex E/AC:2005). The lab concluded that the “compost obtained from the disintegration test in the presence of the sample SL7283 Sioux pre-shrunk has not determined an inhibiting effect on either the germination or growth of both plants analysed at the different tested compost concentrations.”
