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. Skaggs et al. demand in 2016. Skaggs et al. demand in 2016.

Goodyear unveils 90% sustainable-material demonstration tire, approved for road use

Green Car Congress

A sustainable material is defined as a bio-based/renewable, recycled material or one that may be produced using or contributing to other sustainable practices for resource conservation and/or emissions reductions including mass-balance materials. Silica is an ingredient often used in tires to help improve grip and reduce fuel consumption.

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. If HVO is produced from waste feedstocks with low upstream impacts, the high conversion efficiency of the HVO production process will make HVO the preferred fuel to BTL from any woody feedstock, even woody waste.

TU München researchers test behavior of OME synthetic fuels in engines, develop optimized combustion process

Green Car Congress

However, they also have disadvantages: production costs are higher than those of fossil fuels and there are no production facilities available yet. OME made from waste CO 2 and electricity from renewable sources would even be carbon neutral. They determined the optimal parameters for efficient combustion.

Ranges of global technical potentials of renewable energy sources derived from studies analyzed in SRREN report. The authors reviewed more than 160 existing scientific scenarios on the possible penetration of renewables by 2050, alongside environmental and social implications; and then reviewed with four of these in-depth.
