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.

Blue Marble Biomaterials launches first zero-waste chemical biorefinery

Green Car Congress

A photobioreactor and algae perform the “water recycling”; the pelletized solid waste material will be used in the gasifier. has launched the first zero-waste chemical biorefinery in the US in Missoula, Montana. If we have fixed feedstock [such as the waste spent grain], we have price stability. Source: Blue Marble.

Simulation study suggests ORC waste heat recovery system could deliver potential 7% improvement in fuel consumption in a PHEV on highway

Green Car Congress

Starting from a energy-based powertrain simulation model validated on experimental data from the PHEV, the researchers conducted a first- and second-law analysis to identify the potential for engine waste heat recovery, considering a variety of driving cycles and assuming the vehicle operating in charge-sustaining (HEV) mode. Power from ORC.

New simple, energy-efficient process for the direct production of renewable diesel from biomass waste

Green Car Congress

Non-edible carbohydrates are converted to renewable diesel-range liquids via two consecutive catalytic steps. A team at the Universidad Politécnica de Valencia (Spain) has designed a new simple, energy-efficient process (that also does not require any organic solvents) for the production of renewable diesel from biomass waste.
