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.

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

Green Car Congress

They were able to convert amorphous polypropylene and everyday bags and bottles effectively to lubricants with yields up to 80+%. The reaction network involves the sequential conversion of polymer into the oil with a gradual decrease of molecular weight until ?700–800 A paper on their work is published in the journal ACS Catalysis.

Rice, C-Crete team optimizes conversion of tire waste into graphene for stronger concrete

Green Car Congress

Rice University scientists and their colleagues at C-Crete Technologies have optimized a process to convert waste from rubber tires into graphene that can, in turn, be used to strengthen concrete. After useful oils are extracted from waste tires, this carbon residue has until now had near-zero value, Tour said. 2021.03.020.

EU project HyFlexFuel converted sewage sludge and other biomasses into kerosene by hydrothermal liquefaction (HTL); SAF

Green Car Congress

The EU-funded research project HyFlexFuel recently successfully produced biocrudes via hydrothermal liquefaction (HTL) from a variety of biomasses, including sewage sludge, food waste, manure, wheat straw, corn stover, pine sawdust, miscanthus and microalgae in a pilot-scale continuous HTL plant at Aarhus University (Denmark).

Twelve and LanzaTech successfully convert CO2 to ethanol

Green Car Congress

It’s also often produced using corn and other crop feedstocks, but this approach is dependent on crops that otherwise could be used to grow food or waste feedstocks. Our partnership with Twelve provides us with the feedstock needed to create critical resources like ethanol without adding CO 2 to the atmosphere.
