Hatch report finds NOVONIX dry cathode synthesis process offers cost and waste reduction improvements

Green Car Congress

a global engineering consultancy firm, has delivered its report that evaluates NOVONIX’s all-dry, zero-waste cathode synthesis process. The Hatch study found that NOVONIX’s process may potentially reduce power consumption by an estimated 25% and practically eliminate waste byproduct generation over the conventional process.

Li-ion battery waste used in biodiesel production from discarded vegetable oil

Green Car Congress

Brazilian researchers have demonstrated a new chemical approach for producing biodiesel from domestic cooking oil waste by using lithium hydroxide mixed with either sodium hydroxides or potassium hydroxides as catalysts. Author Gilberto Maia de Brito said green engineering can yield solutions for a variety of problems at the same time.

Novozymes launches commercial enzyme technology to convert waste oils into biodiesel

Green Car Congress

waste oils with high FFAs have not been a viable feedstock option. The enzymatic process eliminates the need for sodium methoxide, one of the most hazardous chemicals in traditional biodiesel plants. The enzymatic process uses less energy, and the cost of waste oil as a feedstock is significantly lower than refined oils.

Piedmont Lithium selects Tennessee for second lithium hydroxide project; 30,000 metric tons per year

Green Car Congress

This process eliminates the acid-leaching of spodumene and the production sodium sulfate waste, which will make Tennessee Lithium one of the world’s most sustainable lithium hydroxide operations, according to the company. Front-End Engineering Design (FEED) for Tennessee Lithium will be performed by Kiewit and Primero.

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.

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.
