Fraunhofer team develops process to recycle carbon black from car tires

Green Car Congress

Waste tires have been used mainly for recovering energy sources; only small proportions of the carbon black contained in these tires are recycled, since mineral ash accounts for around 20% of its content. Around three kilograms of carbon black—also known as industrial soot—are found in a standard car tire. © Fraunhofer IBP.

Rio Tinto declares maiden ore reserve at Jadar; major potential source of battery-grade lithium carbonate

Green Car Congress

The project under study consists of an underground mine, sustainable industrial processing and waste facilities as well as associated infrastructure. The campaigns successfully produced unrefined lithium carbonate, boric acid and sodium sulfate at target recoveries without the build-up of detrimental species.

Aqua Metals is building a more sustainable battery recycling ecosystem

Charged EVs

Several companies are developing chemical processes, but these are still at pilot scale, and Aqua’s execs see serious challenges in delivering the required product purity and dealing with waste streams. There are real challenges with waste streams—they yield a lot of sulfuric acid and sodium sulfate, which will need to get landfilled.

Study shows biodiesel blends in buses reduce PM, other harmful exhaust elements, EC and CO

Green Car Congress

In the study, the team investigated the combustion of biodiesel from various types of feedstocks—soybean methyl ester (SME); tallow oil (TO); and waste cooking oil (WCO)—in a variety of volume percent blends (B00, B20, B50, and B100) using a bench-top combustion chamber in a laboratory setting.
