Scientists Seek to Turn Waste Glycerol Biofuels into High-Value Gas
Submitted by admin on December 10, 2008 – 11:17 amNo Comment
For every tonne of biodiesel made from vegetable oil, 100kg of thick, viscous glycerol is produced as a byproduct. The annual 6.8 billion liters of biodiesel production in the EU yields around 680,000 tonnes of crude glycerol. Although some of the sweet-tasting liquid can be purified for pharmaceutical or food applications, the rest ends up as waste. Much of the excess glycerol is currently incinerated. There may be a much more valuable use for this waste material: conversion to hydrogen gas. READ MORE.
