Biogas: Case studies

Production of biogas from organic municipal waste in Brecht, Belgium

The plant was designed to treat 10,500 tonnes per year of source separated bio waste, consisting of vegetable, fruit, garden and paper waste, such as disposable paper products and non-recyclable paper.

Lemvig's bigas plant, Denmark

The plant is a big centralized biogas plant with a total digester volume of 7,600m3. It is designed on the basis of familiar technology, but some original features have been included. The plant is planned to digest 400 tonnes per day of manure and 40 tonnes per day of industrial wastes.

Camphill Community Biogas Project, Ireland

The Camphill Community is a charitable organisation which cares for people with special needs or a disability within the supportive community environment where able bodied and those less able, physically or intellectually, work, live and play together. Camphill has an arrangement with three local farmers who supply slurry to the biogas centre where it is pumped into sealed vesselswhere gas is produced.

The gas is drawn off and used as fuel to heat the buildings in Ballytobin. There are plans to use the gas to generate electricity for use in Ballytobin and to sell to the grid.

The Bromma Biogas Plant in Stockholm, Sweden

In the waste water treatment plant of Bromma, Stockholm, about 10000 tons of sewage sludge (dry matter) is produced annually. Since the 1970's, sludge has been treated by anaerobic digestion producing biogas. In such a plant the sludge is biologically treated under anaerobic conditions.

The upgrading plant separate methane from carbon dioxide, water and other contaminants in order to produce a vehicle fuel of natural gas quality. 1.5 million cubic metres of gas will be produced annually, which corresponds to 1.5 million litres of petrol.

Today (2004) there are four fuel stations in Stockholm providing gas as fuel. Biogas is one of the least environmentally harmful fuels commercially available today.

Biogas-biofuel for Municipal Transport

In order to enhance the air quality of the area, the Municipality of Linköping, Sweden, introduced the use of biogas produced from organic waste as fuel for its urban fleet. In 1998, the number of vehicles running on biogas fuel in Linköping amounted to 57 urban buses and 14 cars, including 4 taxis. 8,000 Nm³ of biogas are supplied daily.
