Estimates of ethanol costs were obtained as follows in a lab study about 5 years ago in Malaysia.These r in Malaysian dollars, the conversion to USD is 1 USD= 3.8 Malaysian dollars. These costs r for 1 kg alcohol as product. Raw material 2.25 kg tapioca starch costing $1.35, enzymes .01 kg costing $0.15. Heat load <1800 Kcal costing $0.06 utilising waste-wood, giving total of $1.56 for these items. 1kg CO2 is costed as a credit at $0.50. Equipment, capital, transport.etc were not estimated since these are minor. Net cost is only $1.06 per kg alcohol. The processes involved are very simple-as simple as the preparation of biodiesel described recently in the website. The CO2 is actually sold to an integrated facility making precipitated silica from organic silicates present in biomass. The CO2 is utilized efficiently in the silica process. Please note that I have not taken CO2 at `dry ice' price. Now the cost of petrol was between $1.50-3.00 in neighbouring countries at this period but not Malaysia where prices were controlled. I am of the opinion that ethanol was in a position to compete against fossil fuels 5 years ago and ,of course, now. However there are still no organizations or companies in Malaysia with which I could partner as an inventor. This is probably the main reason why backyard inventors cannot `strike it rich'. I would like to be informed if the situation differs in the US and how these concepts could be commercialized . Thanks for listening and regards. manickh ------------------------ Yahoo!
