Smart storage and supply of straw for biorefinery

Cereal straw is an interesting raw material for biorefineries. Here, we want to investigate the possibility of using straw with increased water content to increase the supply of straw and for so-called smart storage to examine pre-treatment effect during storage by using the straw’s natural microorganisms.
Through experiments in the lab and full scale, it is investigated under what conditions and to what extent this can be achieved. The experiments are evaluated qualitatively and quantitatively for use in biogas production and as a raw material for other biorefinery processes. Available amount of straw and annual variations if an elevated water content can be accepted at harvest are modeled. Supply systems and business arrangements are developed.
The project group consists of representatives of agriculture, biorefineries and researchers that together have a broad competence and anchoring in the entire value chain, which is important to ensure the project’s focus and relevance.
