U Delaware team develops chemocatalytic process to convert waste polypropylene to lube oils

Green Car Congress

Quantification of critical properties, including pour point, kinematic viscosity, and viscosity index, indicates that the products are promising alternatives to currently used base or synthetic oils. The reaction network involves the sequential conversion of polymer into the oil with a gradual decrease of molecular weight until ?700–800

Li-ion battery waste used in biodiesel production from discarded vegetable oil

Green Car Congress

Brazilian researchers have demonstrated a new chemical approach for producing biodiesel from domestic cooking oil waste by using lithium hydroxide mixed with either sodium hydroxides or potassium hydroxides as catalysts. The work marks one of the first times lithium has been used for such purposes. —Gilberto Maia de Brito.

DOE researchers investigate economic and environmental impacts of converting wet waste to renewable diesel

Green Car Congress

Meanwhile, wet waste feedstocks, such as animal manure and fats, oils, and greases (FOG), represent another important category of resources that could be utilized to produce MCCI bioblendstocks due to its abundant availability. An open-access paper on their results is published in the journal ACS Sustainable Chemistry & Engineering.

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

Green Car Congress

With tuning, the catalyst can achieve a selectivity of 80% toward motor oil (C 21 –C 45 ). 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. A paper on their work is published in ChemSusChem.
