Making Hydrogen From Waste Vegetable Oil

Researchers at the University of Leeds have found an energy-efficient way to make hydrogen out of used vegetable oils discarded by restaurants and other establishments. The process generates some of the energy needed to make the hydrogen gas itself and is also essentially carbon-neutral.

Road Surface Purifies Air by Removing Nitrogen Oxides

Road surfaces can make a big contribution to local air purity. This conclusion can be drawn from the first test results on a road surface of air-purifying concrete, which reduces the concentration of nitrogen oxides (NOx) by 25 to 45 percent.

Formula for the Removal and Remediation of Polychlorinated Biphenyls in Painted Structures

An activated metal treatment system (AMTS) removes and destroys polychlorinated biphenyls (PCBs) found in painted structures or within the binding or caulking material on structures. It may be applied using a “paint-on and wipe-off” process that leaves the structure PCB-free and virtually unaltered in physical form.
