Disadvantages Only produced in small quantities. Emissions contain toxic substances. Disadvantages Large amounts of insecticide used in production. Total energy consumption twice that of gas. Advantages Technology of process of being introduced.
Gas has to be compressed and purified from carbon dioxide.
If the biogas leaked from landfills could be used as a vehicle fuel, the addition of greenhouse gases from leakage and the emission of carbon dioxide would be reduced. Does not increase the amount of greenhouse gases in the atmosphere. Emission of hydrocarbons, carbon monoxide and nitrogen oxide are low. In concentrated form, it is explosive. Gas has to be compressed.
