With an expanding market for upgraded biofuel in many countries, it is important to develop efficient production methods for upgrading wet biomass. The possibilities for heat recovery can be improved if the upgrading process is integrated with other energy-intensive processes, as for example a pulp mill or a sawmill, in a biofuel combine. This work evaluates obstacles and Success factors for forming such biofuel combines with the forest industry. Case Studies and calculations on theoretical cases have been used together with literature references to evaluate how a biofuel combine can be realised and to compile obstacles and success factors for a combine. It could be seen from the case studies that an excess of by-products and waste heat, together with an existing need for investments are important driving forces for the formation of biofuel combines in the forest industry. The market was also identified as an important factor, which can be both an obstacle and a success factor depending on the situation. It was concluded that the existence of a small-scale pellet market near the plant is important for economic feasibility when sawdust is used as raw material. The conditions for the biofuel combine are different depending on the form of ownership. When a pulp mill or sawmill owns the pellet factory, it was concluded that minimising the risk by using well-known technologies can be an important factor for the realisation of the combine.
