Bioplastics are being touted by industry marketers as the solution to plastics pollution. But the idea that bottles and packaging made of plant-based material can simply be discarded and then break down and disappear is false – recycling and reuse are the only strategies that can work.
Coca-Cola calls it the PlantBottle — a new kind of recyclable plastic container, 30 percent of which is made from sugar cane and other plants, with the remaining 70 percent made from traditional oil-based plastic. The company says that PlantBottle packaging now accounts for nearly a third of its North American bottle volume and seven percent globally. Continue reading
Bio-based materials are becoming more mainstream and according to Duke University’s Center for Sustainability & Commerce, over $400 billion worth of conventional manufacturing products are produced each year using biomass, which in many cases are more sustainable than older alternatives. Nonetheless, bio-based alternatives have yet to reach scale due to traditional industry adhering to classic chemistry.
This is beginning to change, as breakthroughs in bio-based materials engineering reach a tipping point. Collective understanding of how microbes work is, for the first time, allowing us to make chemicals in a safer and more environmentally friendly way. It is possible for us to engineer microbes to have specific functions, including a variety of sustainability applications.
