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. Their work, published in the Journal of Renewable and Sustainable Energy , could enable future studies related to the use of lithium from waste lithium-ion batteries. Before, in practice, these were just restricted to sodium hydroxide and potassium hydroxide.

ORNL advancing LDH sorbent to recover lithium from geothermal brine wastes

Green Car Congress

The LDH sorbent is made up of layers of the materials, separated by water molecules and hydroxide ions that create space, allowing lithium chloride to enter more readily than other ions such as sodium and potassium. Domestic production of lithium, the lightest of elemental metals, is considered a priority for the US. It is essential for the manufacturing of lithium-ion batteries commonly used for everything from electric vehicles to cell phones and laptops.

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 idea of enzymatic biodiesel is not new, but the costs involved have been too high for commercial viability, Eversa changes this and enables biodiesel producers to finally work with waste oils and enjoy feedstock flexibility to avoid the pinch of volatile pricing.

Researchers use CaO catalyst to produce biodiesel/monoglyceride blend; avoiding waste glycerol

Green Car Congress

The resulting blend exhibits properties similar to conventional biodiesel, while reducing waste and improving conversion. Biodiesel is produced from vegetable oils or animal fats via a transesterification reaction with a short chain alcohol and a basic catalyst such as sodium or potassium methoxide. The generation of glycerol not only represents a notable performance loss in the process, it is also creating an enormous waste problem.
