A 2nd look at Fuel Conversion Design from Fossil to Alternative Energy - any better idea?

A Philippine Steel Fabrication Plant with its Diesel-fired open-top Galvanizing Kettle (1.5M depth x 1M width x 7M length - with a maintaining temperature of about 400 degree Centigrade) uses up about 15,000 liters of Diesel monthly operating 24x7 weekly. The Plant is located about 10 kms away from Landfills; about 5 kms away from Livestock Farms and from 2 Feedmills; about 100 meters from an Industrial Sawmill. Given the location & the land area (3 hectares) of the Plantsite, we do not find the use of Sun & Wind advisable. Instead, we consider the Change-over from "dirty" Diesel to "clean" BioGas/BioM as likely given that: (1st) Pangea Green Energy Phils (http://www.pangeagreen.biz) is soon to harvest BioGas from a Landfill 10 kms away; (2nd) Mapecon Phils (http://www.mapecon.com/readersdigest.htm) produces "Green Charcoal" (with high BTU) from enzime-treated BioM. What do you think?;
