18: Electicity and Heat from Source-separated Organic Waste in Switzerland

In the Kompogas plant, organic waste from households and industry is fermented to produce biogas, which is either used on-site for electricity and heat production or converted into  vehicle fuel. The residue is a high quality compost for use in horticulture and agriculture. The demonstration project has a capacity of 5,000 tonnes of organic waste per year, serves an area of 50,000 inhabitants and every day  provides 1,500 kWh of electricity to the grid and 3,600 kWh of heat to customers.

20: Use of Incineration Heat from Integrated Waste Treatment in Japan

 The Waste Treatment and Resource Recovery Centre of Toyohashi City in Japan disposes of waste efficiently while making good use of energy and other resources, by integrating the treatment of municipal, agricultural and industrial waste. The Centre supplies heat from the incinerators to local  greenhouses, to the plant and buildings in the Centre, to an adjacent gymnasium and also generates electricity. Compost is also produced from the household organic wastes and animal faeces. (Printed 1995)

29: A Multi-biofuel, Fluidised-bed, District Heating Plant in Sweden (Norwegian Project)

This project started in 1984 with a 65 MW district heating plant, including a 14 MW solid fuel plant. The plant included a specially-designed fluidised-bed boiler, capable of burning all grades of solid fuel, including low grade organic fuel. By 1992 the district heating plant served some 250 detached houses and 6000 flats, as well as several schools and industrial premises. The biofuel boiler provides  almost 60% of the energy required.

33: Refuse-to-energy Plant with Improved Utilisation of  Municipal Waste, Japan

 A new refuse incineration plant in Japan uses high-temperature/high pressure boilers to achieve a thermal efficiency of over  20%. The plant handles 800 tonnes/day of refuse, and generates 24 MWe with a specific power output of 750 kWh/tonne of refuse. Exhaust steam from the plant is used locally for district heating. The 80 tonnes of ash the plant  produces is melted and turned into slag, eliminating the need for a landfill site for final disposal. (Printed 1996)

Mini-Review of Energy Crops and Crop Residues (1998)

The Energy Crops Mini-Review, which was held in Oxford during 1995 and updated during 1997, was led by Dr Caroline Foster from ETSU (UK). The review covered the biomass energy from crops and crop residues, including woody crops, herbaceous energy crops, commodity crops (such as maize, cereals, rape, soy bean, etc), forest residues and crop residues. Contributions from eleven countries have been compiled to identify and compare national policies, barriers to the deployment of biomass energy, environmental considerations and current market enhancement mechanisims. Part of the study is dedicated to describing the different biomass resources and the  conversion mechanisms used. Some case studies of recent projects are included in the report. The final report on the study is now available from the CADDET Centre or CADDET National Teams
