Despite the fact that many households in Sweden have had separate collection of food waste for a long time, large amounts of organic material still end up in residual waste. The project is based on this loss of resources.
The purpose is to investigate the feasibility of using organic waste that has been mechanically sorted from residual waste for the production of biogas and fertiliser.
In the summer of 2025, Sweden’s first facility for the mechanical sorting of organic material from residual waste was completed. This facility provides a unique opportunity to examine the potential of this fraction.
By comparing organic material mechanically sorted from residual waste with source separated food waste, in terms of composition, pre treatment suitability, biogas potential, and the quality of the produced digestate, the project contributes a scientific evidence base.
The aim is to assess whether a mechanically sorted organic fraction can represent a resource efficient alternative in future biogas systems.
