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. The reaction is complete when all of the molecules have been converted into smaller components known as fatty acid esters.

Hence, in order to reduce the cost of biodiesel production, using cheaper feedstocks such as waste oil or low-quality oil has been proposed. However, its use has been challenging as a result of impurities such as water and large amounts of free fatty acids (FFAs), which are common in most waste materials. Click to enlarge.

The only by products are water and a fair degree of heat, the latter indicating a degree of inefficiency and wasted energy. Hence its supply would not be cheap, renewable nor sustainable in the long term. Nonetheless, hydrogen fuel cell cars are, like pure battery powered cars, classed as Zero Emission Vehicles (ZEV).

Robert Dorner and his colleagues are looking at converting CO 2 and hydrogen (both won from sea-water) over catalysts, using the CO 2 as a building block to form synthetic fuel. Our research proposes the utilization of CO 2 into fuel, recycling the gas and using it as a raw material rather than a waste product. Robert Dorner.

Researchers at the Isfahan University of Technology (Iran), have demonstrated the use of a dilute acid hydrolysis process to convert rice straw—a cheap, abundant and mainly unused ag waste—to 5-Hydroxymethylfurfural (HMF) and furfural. Both furans are components for production of different chemicals and fuels.

free) pistons converting their linear motion to rotary via a sinus disc. Waste heat is transferred within the sphere to create steam in a closed process that then drives the second cycle and set of pistons (built around the first set), using a similar sinus disc. Gert Reinhardt was trained as a Mathematician at Dortmund University.

The discovery also improves on current recycling methods that result in cheap, low-quality plastic products. Northwestern University, Argonne National Laboratory and Ames Laboratory led the multi-institutional team. Too, the catalytic method produced far less waste in the process. —Aaron Sadow.

I would say that electricity is a vastly superior fuel for the light vehicle fleet,” said Willett Kempton , a professor and alternative energy specialist at the University of Delaware. Every scrap of waste food, garden trimmings and even sewage would be used to ferment gas.

To deal with this major special waste problem has to my knowledge never ever been brought to the attention of the readers of any paper around the world. Batteries are highly special toxic waste and cannot be dropped on the average dump site, so who is going to pay to get rid of this problem? — Jeff U 6.
