Researchers detect broad range of emerging synthetic antioxidants in dust in e-waste recyling centers

Green Car Congress

Manufacturers add synthetic antioxidants to plastics, rubbers and other polymers to make them last longer. Now, researchers have detected a broad range of emerging synthetic antioxidants, called hindered phenol and sulfur antioxidants, in dust from electronic waste (e-waste) recycling workshops, possibly posing risks for the workers inside.

LanzaTech and Sumitomo Riko partner to produce isoprene from rubber, resin and urethane waste; substitute for natural rubber production

Green Car Congress

LanzaTech and Sumitomo Riko Company have entered into a joint-development agreement to reuse rubber, resin and urethane waste for the production of a key chemical intermediate, isoprene. Isoprene is produced by plants, and along with its polymers, is the main component of natural rubber. —Jennifer Holmgren, CEO, LanzaTech.

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.

Dalian team devises two-step method for synthesis of jet-range polycycloalkanes under mild conditions from plastic waste

Green Car Congress

Researchers at the Dalian Institute of Chemical Physics in China report a two-step method for the synthesis of jet-fuel-range high-density polycycloalkanes from polycarbonate waste under mild conditions. Plastics are a family of organic polymers which are widely used in our life. Since 1950s, about 6.3 Tang et al.

ETH Zurich catalyst can convert polypropylene directly into motor oil with high selectivity

Green Car Congress

The recycling of plastic waste plays a large conceptual role in the quesst for the realization of a circular economy. Polypropylene constitutes about 30% of all plastic waste. The nanoparticles were supported on a carbon material synthesized via the carbonization of an aniline/phytic-acid-based polymer. Shibashish D.
