Did you know that approximately 25 billion unworn garments end up in landfills every year? The fashion industry has a serious waste problem, and because of Petrol-Based synthetic yarns, discarded jeans take hundreds of years to decompose, leaving a negative impact on the planet. With this problem in mind, Candiani set out to find a solution, COREVA™, the world’s first compostable stretch denim.
WHAT IS IT
COREVA™ is an innovative technology developed and patented by CandianiDenim that uses a GOTS approved plant-based yarn obtained from 100% natural rubber. When combined with organic cotton this results in a yarn that is completely natural and plastic-free. COREVA™ replaces conventionalsynthetic and petrol-based elastane often used in stretch denim with Candiani’s new, custom-engineered, biobased component. With this technology Candiani has achieved an innovative compostable stretch denim fabric - without compromising the elasticity, physical qualities, and durability of jeans.
WHAT ARE THE BENEFITS
As this technology is made with natural rubber, it is the first renewable, plant-based alternative to synthetic, non-renewable petrol-based elastane. COREVA™ has been tested to prove its compostability, in mature compostin less than six months, without releasing the toxic chemicals and microplastics of conventional elastane, in compliance with the EU Standard EN13432 – offe ring an eco-compatible, end-of-life solution for stretch denim.CIRCULARITY OF THE RAW MATERIALSThanks to COREVA™, Candiani has created a truly circular and regenerative model in which natural materials are turned into fabric, then garment, and,instead of being thrown away, COREVA™ returns to the earth naturally, leaving a positive impact on the environment.

COREVA™ has undergone tests to assess biodegradability, disintegration, and eco-toxicity. These tests, when put together, determine compostability. The tests were conducted at Innovhub following the requirements of the EU Standard EN 13432. As there is not yet a dedicated compostability test for fabric such as COREVA™, Innovhub selected the closest material category possible, packaging, to test COREVA™’s biodegradability and compostability status.
At the end of 12 weeks, the sample disintegrated at 98.1% of it’s original value therefore, it falls within the limits specified.
EVALUATION OF THE COMPOST CREATED BY COREVA™
Once confirming the compostability of COREVA™, it was necessary to test the soil where the fabric composted to determine its ecotoxicity. The pythotoxic effect test* was conducted with two different types of seeds: mung bean (Vigna radiata) and barley (Hordeum vulgare). The sowing was conducted in pots filled with a mixture containing the compost created by COREVA™ and compost created by control material. The results determined there was significantly more growth from the COREVA™ compost than the sample material.
