Modeling and optimization of a regional waste-to-energy system: A case study in central Sweden

摘要

The county of Vaestmanland, a region located in the center of Sweden, is used here as an example in the conversion of agricultural or forestry waste (biomass) to liquid biofuels to replace fossil fuels in the transportation sector. An optimization of the current status of the energy system is performed to determine the amount of waste for incineration/combustion and bio-digestion that can be used for energy recovery and understand the manner in which the primary energy demand is satisfied. An analysis of the scenarios for the next decades aims to find a potential scenario through which a sustainable society can be achieved by constructing a regional energy system without fossil fuels.
