Biodiesel in Argentina
Posted by Big Gav
TreeHugger has a post up on the production of biodiesel in Argentina. Once again conerns are raised that the key to producing biofuels in an economic fashion requires a lot of human labour.
The Spanish headquartered oil firm Repsol is planning to produce biodiesel in Argentina through the use of "advanced technology". Biodiesel is made through a chemical process in which the vegetable oil reacts with alcohol in the presence of a catalyzing agent. Glycerin, for which there are over 1,500 uses, is a valuable by-product of biodiesel synthesis. In this case, the glycerin would be from natural sources and potentially regarded as "organic".
Apparently Brazil is also developing a program to produce biofuel for export. This TreeHugger is reminded of of a "BioMass Energy" conference in the early 1980's at which a Brazilian expert gave a complete history of that nation's sucessful and large scale ethanol production for transit fuel use. The slides shown of field laborers hand cutting sugar cane to "feed the beast" of sugar mills and then ethanol refineries put a chill in my spine as I suddenly realized that rainforest clearing and "low paid" labors of indigenous peoples were part of the equation.
