Biogas, a clean fuel

For transport and cooking

Air pollution is now the world’s largest single environmental health risk. The World Health Organization (WHO) reports that in 2012 around 7 million people died — one in eight of total global deaths — as a result of air pollution exposure.

“Excessive air pollution is often a by-product of unsustainable policies in sectors such as transport, energy, waste management and industry. In most cases, healthier strategies will also be more economical in the long term due to health-care cost savings as well as climate gains,” says Dr. Carlos Dora, WHO Coordinator for Public Health, Environmental and Social Determinants of Health.

However, organic waste is the raw material for the production of biogas. By an anaerobic digestion process in which microorganisms decompose biodegradable materials -waste-water, food waste, manure, vegetable waste …- in the absence of oxygen, is generated biogas and organic fertilizer. Low cost home digesters solve the problem of pollution inside homes, by producing biogas which can be used as fuel for cooking. Keep in mind that some 3 billion people are living in households where wood, charcoal or dung is used as fuel for cooking.

Biogas plants with large-scale digesters produce and liquefy biogas for use as fuel in all types of vehicles, from motorbikes and cars and trucks and, soon, intrains and planes. This emerging solution for a clean, inexpensive transportation can contribute decisively to solve the problem of air pollution.

The biogas aims high: British Airways, in a pioneering decision, will begin to use biogas as fuel for aircraft.
