Novel energy and resource-efficient value chains through co-combustion of straw fuels and sludge

Sweden has an untapped potential of straw fuels of 20 TWh on unused arable land of approximately 700 000 ha and further 4 TWh in the form of unused straw. The operational challenges of straw fuels can be solved in co-combustion with sludge, there is thus an opportunity to combine agricultural residual streams with sustainable food production and bioenergy.
The project develops new actor constellations in the form of intra- and intersectional collaborations in order to enable sustainable value chains for the co-combustion of straw fuels and sludge, attractive value chains that are energy and resource efficient, and can be used both nationally and globally. The project develops new technical process solutions required for the value chain, for example in terms of fuel quality through co-briquetting and examining quality of the ash produced. Additionally, legal barriers, opportunities and techno-economic and environmental aspects are evaluated to enable the realisation of the value chain.
