Integrated biomass-based production of district heat, electricity, motor fuels and pellets of different scales

► District heat from integrated production options are cost and primary energy efficient. ► Coproducing of bioelectricity is more cost-efficient than coproducing biomotor fuels. ► There is great potential to polygenerate biopellets in district heat production systems. ► Composition and cost of district heat production depend on the scale of the system.
