Getting Real About Plastic

We admit to optimism as recently as three months ago on this issue, which we have been reading about since five years ago. Thanks to Jim Robbins for keeping it real:

Why Bioplastics Will Not Solve the World’s Plastics Problem

Coca-Cola’s new PlantBottle is made from 30 percent sugar cane and other plants, with the rest made from traditional oil-based plastic. COCA-COLA

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

Understanding Biomaterials

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.
