Of the 8.2 billion tonnes of materials consumed in EU countries in 2007, biomass accounted for 21 % and fossil fuels for 23% and the amount of biomass used is likely to increase. According to the European Environment Agency (EEA), the usage and effluent of nutrients are decreasing or stabilising. However, 33% of European rivers and lakes show signs of eutrophication and a substantial proportion of Europe’s freshwaters are at risk of not reaching “good environmental status” by 2015. Aquatic environments hold large volumes of biomass, such as mussels, algae and reed, which could be used for example for energy production, ecologic animal feed, chemicals, medicines and water purification. These resources, also serving as cleaning agents of the waters removing pesticides and heavy metals, act as preventers of eutrophication, for storing nutrients and CO2. These resources are generally regarded as waste because of lack of knowledge and strategies regarding appropriate resource management.
The BUCEFALOS project’s overall objective is to demonstrate a holistic approach to regional coordination for sustainable resource management of aquatic biomass. Thie project will demonstrate innovative methodologies and technological applications for cultivating and harvesting mussels. It will also restore wetlands and establish algae cultivation sites with a view to cleaning freshwater and providing efficient yields of biomass for biogas.Specific objectives of the project are to:

1. Demonstrate methodologies, tools and stakeholder communication for the regional co-ordination of sustainable resource management of aquatic biomass;
2. Demonstrate methods and techniques on a concrete business/action level that both contribute to the cleaning of water and air and also make profitable and sustainable use of aquatic biomass;
3. Establish and demonstrate a full-scale mussel cultivation site in the Baltic Sea;
4. Demonstrate vertical harvesting of mussels on submerged artificial constructions;
5. Establish and demonstrate a number of wetlands and algae cultivation sites with the dual purpose of cleaning water and producing biomass for biogas;
6. Establish and demonstrate a full-scale biogas plant for biogas production from aquatic biomass; and
7. Assess and test a number of usage areas and applications for aquatic biomass, including waste products.

Expected results:

1. A set of tools, models and operation strategies for a regional co-ordination for sustainable resource management of aquatic biomass (GIS tool, reports);
2. A full-scale mussel cultivation site in the Baltic Sea;
3. A full-scale harvester for mussel cultivations around submerged artificial constructions;
4. 2-5 full-scale wetlands for water remediation and biogas production;
5. 2-5 full-scale algae farms for water remediation and biogas production; and
6. A full-scale biogas plant for biogas production from aquatic biomass.Expected achievements within the project period (in brackets, ongoing achievements after the project has ended):

1. A 12.5-tonne reduction in phosphorus levels (6.25 tonnes/yr);
2. A 155-tonne reduction in nitogen levels (77.5 tonnes/yr);
3. An 800-tonne reduction in CO2 emissions as a result of biomass growth in the wetlands and algae cultivation sites (400 tonnes/yr);
4. A 1 442-tonne reduction in CO2 emissions from replacing fossil fuels with biogas (721 tonnes/yr); and
5. It is forecast that the projects plant in Trelleborg will be able to generate 401 500 Nm3/yr of biogas and produce 2.71 Gwh/yr of renewable energy.
