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.

A*STAR team combines fungal culture and acid hydrolyses for cost-effective production of fermentable sugars from palm oil waste

Green Car Congress

Researchers from A*STAR in Singapore have developed a fungal culture for use in a cheap and efficient method to transform waste oil palm material into biofuels and environmentally friendly plastics. The palm oil waste contains cellulose and hemicellulose that can be broken down into sugars for use in fuel and plastic production.

Electra raises $85M to advance Low-Temperature Iron process; electrochemical refining at 60?C

Green Car Congress

Electra’s process emits zero carbon dioxide emissions and carries zero green premium, meaning it will cost the same or less than existing production methods powered by fossil fuels. Electra has raised $85 million to produce Low-Temperature Iron (LTI) from commercial and low-grade ores using zero-carbon intermittent electricity.

Study finds relying on “local food” a distant dream for most of the world

Green Car Congress

Globalization has revolutionized food production and consumption in recent decades and cultivation has become more efficient, and as a result, many people’s diets have diversified and food availability has increased in various parts of the globe. In comparison, the global average is about 3,800 kilometers. —Pekka Kinnunen.

Study finds renewable fuels from hydrotreated vegetable oils outperform transesterified lipids and BTL from woody material in environmental lifecycle impacts and costs

Green Car Congress

GHG emission comparison between fossil diesel, transesterified lipids, HVO and woody BTL. To expand biofuel production and use, they found that the next preferable feedstock is likely residual woody biomass for BTL. Fuel yield and energy efficiency is low in BTL production. Sunde et al.
