This article presents information on the use of methane fuel as a power resource in Europe. One of the European cities is running one train, 67 buses and 80 cabs entirely on biogas, a methane fuel made primarily from cow intestines and other slaughterhouse waste. Biogas releases significantly fewer emissions than diesel and gasoline and can also be extracted from manure and human sewage. To convert cows into methane, intestines and other unused organs are shredded into a slurry, pasteurized for at least an hour and placed in a sealed, oxygen-free digester.
