The joint solutions from Covestro and Alibaba Cloud have already been successfully implemented in the consumer goods sector. Covestro collaborated with China's leading beverage maker, Nongfu Spring, to recycle 19-litre water barrels into post-consumer recycled polycarbonate. This recycled material was then used by KACO, a niche stationary brand in China, to produce gel pens. With Alibaba Cloud Energy Expert’s carbon emission accounting and digital tools, consumers can scan a QR code on the pen packaging to trace the material’s origin, see a detailed breakdown of the carbon footprint at each production stage, and understand the carbon emissions reduced compared to using virgin materials.
