Strengell summarized future challenges for integrated biorefineries and biofuel plants.
Challenges include competition for raw material; process technology, which “doesn’t exist yet at the industrial scale”; the complex process setup; demanding energy and process integration; and the market supply and demand relationship for multi-production, wood paying capability, and optimal use of biomass.
Strengell described two studies. The first evaluated the constraints and benefits of integrating biofuel production with a KPPM. This study looked at liquid biofuel production in the global context and the potential share of wood-based biodiesel. It evaluated the constraints of biomass availability and the number of suitable production sites.
