ComparisonTextile Recycling Methods
Achieving 100% resource recovery. Reaching a level unattainable by other methods.
While material and chemical cycles require material separation and result in moderate to high levels of CO2 emissions, CIRCULAR CARBONs carbonization technology processes clothing, including blended materials and accessories, in a single batch without separation, achieving approximately 80% CO2 reduction compared to incineration. With a 100% recycling rate, it can be used in a variety of applications such as soil conditioners, building materials, and adsorbents, and significantly surpasses other methods in terms of alignment with SDGs 12 and 13.
