UN Study says biogas from human waste could power millions of homes

Biogas from human waste has the potential to generate electricity for millions of homes while improving health and protecting the environment, a United Nations University institute said on Tuesday.

The biogas potentially available from all the human waste in the world would be the equivalent of up to $9.5 billion (€8.67 billion) worth of natural gas a year and could produce electricity for as many as 138 million homes, the UN Institute for WaterEnvironment and Health said in a study.

In low-income countries, the use of biogas - generated by bacteria breaking down the waste - could finance development, it said.
