The current predominant method for the transesterification of triglycerides (plant and animal oils and fats) to biodiesel (a mixture of esters) uses chemical catalysts (sodium or potassium hydroxides or alkoxides). Concerning biodiesel production, lipase immobilisation adds an extra cost to the process and partial inactivation may also occur.

They used nickel and aluminium as materials for the cathode and anode respectively, with sodium aluminium tetrachloride (NaAlCl 4 ) as the molten-salt electrolyte—all relatively cheap, earth-abundant materials. However, in the PNNL team’s demonstration, the freeze–thaw mechanism of the molten salt is able to circumvent that problem.

The new technique employs an abundant and environmentally benign sorbent: sodium carbonate (the main ingredient in baking soda). These permeable silicone beads could be a “sliced-bread” breakthrough for CO 2 capture—efficient, easy-to-handle, minimal waste, and cheap to make.

Two chemists at Brown University have streamlined the conversion of waste vegetable oil (WVO) into biodiesel, eliminating the need for corrosive chemicals to perform the reactions. Current techniques for the conversion of waste vegetable oil to biodiesel take time, are costly and are inefficient. That makes the process less efficient.
