北京快3线路 www.4w1e.cn Today, most chemical building blocks and materials are still produced from fossil resources, which pose a range of challenges from environmental to economic and security of supply. Switching to a bio-based feedstock model would protect against supply dependency and generate a lower carbon footprint, create more sustainable production systems, and strengthen the competitive position of the bio-based chemicals industry. Specifically, this switch could cut up to 85% of CO2 emissions compared to fossil-based value chains.
