Green Distillation Technologies (GDT) can produce 3,000 liters of bio-oil from one giant seven-ton mining truck tire. It hopes to increase production to more than 8 millions liters annually by mid-2017. Director Trevor Bayley said the company used a technique known as destructive distillation to convert wasted, old rubber into renewable energy.
What is remanufacturing? What are its additional economic or environmental benefits, and how does this industrial practice differ from reuse or recycling? This adapted chapter, "Remanufacturing and the circular economy," answers these questions with compelling case studies that illustrate the power of the circular economy model.
Silicon is the second most abundant element in Earth’s crust after oxygen, but carbon-silicon bonds are unheard of in nature: Neither biological organosilicon compounds nor biosynthetic pathways to create them have been identified. But when given the right starting materials, some heme proteins can stereospecifically form carbon-silicon bonds, report researchers from Caltech.
To find a renewable way to produce green fuels and chemicals, scientists have developed technologies that use sunlight to split water to make molecular hydrogen or reduce CO2 into hydrocarbons. However, these artificial photosynthesis and electrocatalysis technologies face significant research and engineering development challenges to produce fuels efficiently and economically.
AMSilk, located near Munich, is the world’s first biotech supplying synthetic silk biopolymers for textiles, cosmetics and medical devices. The company’s 100% biodegradable and vegan Biosteel fibers, stronger and lighter than conventional synthetic fibers, have been used by Adidas to create sustainable sneakers.
