Researchers from the Arctic Technology Center (in Sisimiuth, Greenland) are looking into the utilization of waste Greenland-shark meat as a raw material for biofuel, in the form of biogas. Biogas is a mixture of methane and carbon dioxide which is produced from the anaerobic (oxygen-free) fermentation of any biodegradable organic matter. Biogas is also primarily used for heating, cooking, or for electrical power generation. Greenland sharks are said to be "nuisance" species to fishermen, and their meat is non-edible (even toxic) for human consumption. Thousands of these sharks are often caught and die in fishermen's nets off Greenland every year. Greenland shark meat is also a major by-product of the Greenland fishing industry, according to the Biofuels International website. Marianne Willemoes Joergensen of ARTEK's branch at the Technical University of Denmark, and project manager, says that the shark meat, when mixed with macro-algae and household wastewater, could "serve as biomass for biofuel production." The by-product shark-meat biofuel is estimated to have the capability to power 13 % of energy consumption in the village of Uummannaq with its 2,450 inhabitants. Test runs at an organic waste treatment plant is scheduled for next year. If successful, the project "could help the many isolated villages on the vast island to become self-sufficient in terms of energy"..
