Biogas for Cooking
Reduced / Sequestered
(To Implement Solution)
This is a new solution; a summary is forthcoming.
Small biogas reactors can be installed in homes and communities to enable cooking with biogas instead of wood and charcoal stoves, which have health and environmental consequences. It is projected that by 2050, small biogas digesters that digest animal and crop wastes can replace 57–87 million inefficient cookstoves in countries in Asia and Africa. The cumulative result: 4.6–9.7 gigatons of carbon dioxide emissions avoided at a net cost of US$25–52 billion. These stoves increase operating costs, however, by an additional US$100–209 billion over the lifetime of the reactors.
