Canadian company develops the alternative ecologically clean of energy fuel- from the new source, which all this time was under the nose, from the human excrements, he writes The Guardian.
Scientists from the group of the development of the biological fuel Dynamotive assert that fuel-, obtained from the human dirtiness, can be used instead of other organic materials for obtaining of heat and energy in diesel motors and steam boilers. They successfully carried out transformation at the level of a pilot study and they want to bring process to the commercial level of volumes.
Andrews Kingston, the President and Director-General Dynamotive, he says: "now there are no technical complexities whatever, which would prevent us from using human excrements. If we be able to supply fuel-, people will it use ".
During February 2005 the company opened the production of the commercial level in Ontario - enterprise it produces 22 thousand tons of biological fuel from the chips of wood per year it sells to its local enterprises.
Kingston indicates that as the base for preparing the fuel it is possible to use more than hundred varieties of biological withdrawals. Company already derived on the commercial level the production of fuel from the wood, obtained from the construction withdrawals and the shell of coffee grains. "now we examine dirtier withdrawals, like the hen dung, cow's manure and everyday rubbish", he says.
Withdrawals are led by rapid heating to the temperature of 400-500 degrees according to Celsius in the oxygen-free medium (method of pyrolysis), after which the carbon-containing gases are condensed, being converted into the dark brown dense oily liquid. Other hot gases are processed and are used in the process of heating, leading its efficiency approximately to 80%.
The biological forms of fuel are considered ecological, since carbon, which is freed during the combustion of fuel, earlier was absorbed from the atmosphere by the plants, used for its production.
