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.

LanzaTech and Tadweer to explore collaboration on large-scale conversion of municipal solid waste to alternative fuels

Green Car Congress

The carbon found in municipal solid waste, which is piling up in landfills or being incinerated globally, can play a critical role in eliminating the virgin fossil resources used to make fuels and chemicals. It is a testament to the UAE’s leadership and strong sustainability agenda that our technology has found a home here.

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. —James Tour.

DOE to award $30M to support production of rare earths and other critical minerals from coal-based resources

Green Car Congress

The US Department of Energy (DOE) announced up to $30 million to help lower the costs of the onshore production of rare earths and other critical minerals and materials from domestic coal-based resources. ( However, rare earth elements occur naturally, including in domestic coal and coal wastes.
