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.

Audi and KIT working on recycling for automotive plastics via pyrolysis oil

Green Car Congress

Whereas plastics of the same type can often be mechanically recycled, recycling of mixed plastic waste poses a major challenge. We want to establish smart circular systems in our supply chains and make efficient use of resources. These plastic components are processed into pyrolysis oil by chemical recycling.

Researchers use distillation to improve biocrude oil properties for fuel blending

Green Car Congress

Biocrude oil produced via hydrothermal liquefaction (HTL) of biomass could provide a low-carbon supplement for transportation fuel supply. However, physical processes—such as fractional distillation as used in oil refineries—are cheaper and more reliable. Distillation increased the H:C (4.2–13.7%); 1 , respectively.

Neste Oil produces NExBTL renewable diesel from waste fat sourced from the fish processing industry

Green Car Congress

Neste Oil has again expanded the range of renewable raw materials it uses by beginning to produce NExBTL renewable diesel from waste fat sourced from the fish processing industry at its Singapore refinery. After the fillets have been removed, the fat content of the gutting waste can be as high as 30-35%.

IEA: governments must act to ensure sufficient supply of critical minerals to meet net-zero goals

Green Car Congress

Demand outlooks and supply vulnerabilities vary widely by mineral, but the energy sector’s overall needs for critical minerals could increase by as much as six times by 2040, depending on how rapidly governments act to reduce emissions. Source: IEA. The expansion of electricity networks also requires a huge amount of copper and aluminum.
