Introduction

In order to demonstrate and evaluate this novel concept we have gathered a dedicated group consisting of one municipality, different biological and technical researchers and a regional agricultural association. The partners come from Sweden, Denmark, Germany and Bulgaria.

The project has been divided into the following work packages;

• Co-ordination,
• Procurement,
• Building,
• Communication,
• Analysis of socio-economic aspects,
• Dissemination,
• Evaluation of the co-digestion process,
• Evaluation of the rural-urban biogas system and
• Conclusions with a final report.

Activities

The AGROPTI-gas project will demonstrate a novel concept for the profitable production of renewable energy in the form of biogas as a vehicle fuel. A full-scale system for co-digestion of biological household waste and agricultural feedstock will be built and the digested slurry will be used as a natural fertiliser. By using novel process techniques, including new components, a unique low water content production and distribution system can be achieved, which optimises the whole system including logistics.

If the demonstration in full-scale proves successful, the system has a large potential in Europe with large environmental benefits as an outcome. The environmental benefits are in the form of decreased emissions of greenhouse gases, improved air quality in the cities due to cleaner vehicle fuel and optimal circulation of nutrients with less need for artificial fertiliser.

Progress

The pre-project is now finished and the application for the environmental permit was sent to the County Administration Board in September 2002. There have been a number of meetings with local interest groups and with surrounding municipalities. Negotiations are in progress with these municipalities about the deliver y of biowaste, and with farmers about the delivery of silage and digested slurry. The tender documents for the public tender have been produced and are now out on the market. A PowerPoint presentation showing the animated Biogas plant, together with the animated pump station, has also been produced.
