Environmental Impacts of Bioenergy
Environmental Assessment of Biofuel Production Using Waste Wood Integrated in a Large-Scale Steel Mill
Short Introductive summary
The methodological approach of the environmental assessment of waste wood used for biofuel production integrated in a large-scale steel mill is described. Therefore, the approach, the system and the environmental impacts of the use of waste wood in a steel mill are presented. This work is part of the H2020 project TORERO (TORefying wood with Ethanol as a Renewable Output: large-scale demonstration). This project demonstrates a cost-, resource-, and energy-efficient technology concept for producing bioethanol from waste wood, integrated in a large-scale steel mill. Wood waste is converted to biocoal by torrefaction, biocoal replaces fossil powdered coal in a steel mill blast furnace. Carbon monoxide and hydrogen in blast furnace exhaust fumes is microbially fermented to bioethanol, while material and energy loops of the process are closed to a very large degree. The results of the environmental assessment using the methodology Life Cycle Assessment (LCA) show, the importance of including the whole value chain and comparing the results to the actual situation to evaluate the environmental impacts of waste wood use.
