Turning Organic Waste Into Vehicle Gas
Detailed description of the Good Practice
In Sundsvall, the project Integrated Biogas Plant, phase 1, aims to identify a long-term sustainable solution for handling industrial bio sludge and organic waste while at the same time using it as the raw material for the production of foremost vehicle gas.
The project indicates the requirements for building a major plant for large-scale composting: it is expected that a plant can go into operation in 2012. During the project period a smaller plant has already been established as well as a temporary gas station for 2 garbage trucks. A commercial gas station is to be opened in central Sundsvall in April 2009.
Objectives of the Good Practice
The project goal is to identify a long-term and sustainable solution for handling industrial biosludge and organic waste while at the same time using it as the raw material for the production of foremost vehicle gas. The project is to answer the question of how such a plant can achieve the desired effects. Large-scale, joint processing of the sludge and organic waste in the region with a large, comprehensive and systematic approach would generate considerable environmental and economical benefits.
Phase 1 is running from 1 January 2008 till 30 June 2009. A plant is expected to go into operation in 2012.
Participants of the Good Practice
- The Municipality of Sundsvall is leading the project
- A number of stakeholders in the region will directly benefit from such a facility
Target group of the Good Practice
Stakeholders such as:
- MittSverige Vatten AB (MSVAB) wastewater treatment plants
- The SCA Ortviken paper mill
- The municipal waste management company, REKO
Funding of the Good Practice
At least a part of the funding came from the European Union Regional Development Fund
More Details of the Good Practice
A joint, large-scale composting facility will deliver sustainable handling of sludge and organic waste and, at the same time, produce significant quantities of biogas that can be upgraded into vehicle gas. The residuals after composting can be dried and granulated for use as forest fertiliser. In doing so the sludge is returned to the eco-cycle. The possibility for other interested parties and small municipalities to deliver organic waste can be realised.
Drying and granulating the residuals, after the gas has been harnessed, requires heat. The Korsta Combined power and heating plant (Korstaverket) shifts to increased electricity production during warmer periods and part of the surplus heat is cooled off. It would be possible to utilise a portion of this surplus heat in a large-scale facility where there is a need for heat for drying sludge and the granulation process.
