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. Before, in practice, these were just restricted to sodium hydroxide and potassium hydroxide.

Novozymes launches commercial enzyme technology to convert waste oils into biodiesel

Green Car Congress

Most of the oils currently used in biodiesel production are sourced from soybeans, palm or rapeseed, and typically contain less than 0.5% 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.
