Plastic Alternatives: Bio-Based Plastics and Scaling Innovation
In this episode, we delve into the world of alternative plastics. As plastic usage continues to rise, against a backdrop of climate change and the need to reduce emissions and waste across the globe, there is a desperate and time-sensitive need to scale plastics that don’t cost the earth. Lignin Industries is a Swedish-founded company that has done just that, having developed a new bio-plastic from lignin, the second most abundant organic material on Earth. CEO Fredrik Malmfors is this week’s guest.
Fredrik Malmfors joined Lignin Industries in April 2023. His background includes 17 years at Accenture, over two spells. His final position at Accenture was leading their Nordic supply chain work. Malmfors' time at Accenture was punctuated by several years at Swedish agricultural cooperative Lantmännen (agriculture, machinery, bioenergy and food products in 20+ markets) in senior leadership positions.
