Increasing the use of wood fuel in a pulp and paper mill: investment opportunity and external costs
2002 (English)In: Proceedings of the 10th Biennal Bioenergy Conference, 2002, 174- p.Conference paper (Refereed)
Wood fuel is a by-product produced in large quantities in the pulp and paper industry. It is a relatively cheap energy carrier that can be used to satisfy the internal demand for heat and electricity. Furthermore, it can replace the use of fossil fuels and thereby reduce emissions of CO2 and the related external costs. The aim of this study is to analyze the economics of using more wood fuel for energy purposes, as well as the economics of using wood fiber sludge as a fuel instead of delivering it to landfills. A pulp and paper mill in Sweden is analyzed and the study focuses on providing a demand for heat and electricity. An energy system model based on mixed integer linear programming is used to perform the study. The analysis illustrates the investment opportunity of a new boiler fuelled with bark and sludge. A business economic approach is compared with a socio-economic approach, in which some external costs are considered. The result of the comparison is that the investment opportunity for a wood fuel-boiler is greater when the external cost of production is considered. Furthermore, the amount of emissions associated with the energy conversion and related external costs is estimated for the different cases.
