ORNL advancing LDH sorbent to recover lithium from geothermal brine wastes

Green Car Congress

These plants pump hot water from geothermal deposits and use it to generate electricity. 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.

Brown Chemists Develop Process to Simplify Waste Vegetable Oil to Biodiesel Process, Chart Progress of Transesterification Reaction

Green Car Congress

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.
