Institutional biogas production from separated organic waste in a community and a boarding school
The “Give Gas” project turns about 100 tons of organic waste into natural gas per year, using two institutional biogas facilities located in the “Hadassah Ne’urim” boarding school in the Sharon region, and in Moshav Adderet in the Ella valley.
Bacteria have been turning organic matter into gas in the absence of oxygen in swamps, digestive systems and below ground for millions of years. This process has created gas reserves and is responsible for the stench of decomposition. In Israel there are a few biogas installations which turn wastewater sludge and cow manure into biogas and burn it for electricity. The master plan for national waste invites developers to build huge facilities for “anaerobic digestion”, but this solution relies on transporting waste for treatment, while possibly weakening the necessary effort for source organic waste separation. Central facilities will never proclaim and demand human responsibility for the environmental damage we produce.
In the “Give Gas” project we operate two experimental institutional facilities that produce biogas for cooking and heating without conversion into electricity. At the Hadassah Ne’urim Boarding School the students separate about 200kg of surplus food and leftovers, and feed it into the biogas facility adjacent to the kitchen. Bacteria turn waste into biogas which burns and heats water for the dishwashing machine. Prior to this project, all food waste was transported and landfilled, while the dishwasher’s water was heated by electricity.
At Moshav Aderet in the Ella valley, the regional council involved 100 households and youth in the community to separate organic waste at home. Youths who work for the project collect 700kg of garbage per week from the yards, and feed it into the biogas facility at the Moshav. The facility provides gas for cooking, heating water for showering and dishwashing. Here too, the project changed a reality of burying organic waste and using fossil fuels, and today the Moshav’s garbage is used to produce renewable energy.
