Simple process transforms PET plastic into a nanomaterial for supercapacitors

Green Car Congress

UC Riverside (UCR) engineers have developed a way to recycle PET (polyethylene terephthalate) plastic waste, such as soda or water bottles, into a nanomaterial useful for energy storage. Then, using an electrospinning process, they fabricated microscopic fibers from the polymer and carbonized the plastic threads in a furnace.

U Oregon team advances effectiveness of catalytic water dissociation in bipolar membranes

Green Car Congress

Researchers at the University of Oregon have advanced the effectiveness of the catalytic water dissociation reaction in bipolar membranes. The technology behind bipolar membranes, which are layered ion-exchange polymers sandwiching a water dissociation catalyst layer, emerged in the 1950s. —Oener et al.

BMW i Ventures invests in Natural Fiber Welding; plant-based leathers, yarns and foams

Green Car Congress

MIRUM is made with natural, biodegradable polymers. Synthetic polyurethane-based leathers require around 5 kg carbon dioxide equivalent per kg of synthetic polymer produced. MIRUM requires no tanning and is made from natural polymers and materials (e.g., waste’ cork powder).

Novomer demonstrates large-scale production of polypropylene using waste CO2

Green Car Congress

has completed the first successful large-scale production of a polypropylene carbonate (PPC) polymer using waste CO 2 as a key raw material. The PPC polymer production run, conducted by Novomer in collaboration with specialty chemical manufacturer Albemarle Corporation, tested scale-up of Novomer’s novel catalyst technology.

Audi introduces new CNG A3 Sportback

Green Car Congress

The ultra high-strength outer shell comprises two layers: an inner layer of carbon fiber-reinforced polymer (CFRP) and an outer layer of glass fiber-reinforced polymer (GFRP). More than half of them sell biomethane produced entirely from waste, and this number is increasing. The inner layer is a gas-tight polyamide vessel.
