Tiivistelmä
This study examines the potential for achieving negative carbon emissions in the forest industry through the integration of biochar production and carbon capture technologies. The study focuses on the technical and economic performance of different system configurations including biochar only, carbon capture only and combined systems in which both approaches are applied simultaneously. The purpose of the work is to evaluate how these alternatives may contribute to net CO₂ removal and how they compare in terms of energy use and economic feasibility.
The theoretical part of the study reviews the principles of pyrolysis, biochar formation, carbon capture and negative emission technologies relevant to the forest industry. The study is limited to a comparative techno-economic assessment and does not include detailed engineering design, permitting or full-life cycle environmental analysis beyond the selected system boundaries. The results indicate that both biochar production and carbon capture can contribute to negative emissions, but their performance depends heavily on process configuration, carbon retention, energy requirements and cost assumptions. Carbon capture only systems offer higher net CO₂ removal potential although they may involve high utility demand and investment cost. The comparison of levelized carbon removal costs shows that the balance between technical performance and economic feasibility is a key factor in determining the attractiveness of implementation the alternative.
The study concludes that integrating biochar production with carbon capture may provide a promising pathway for increasing negative emissions in the forest industry. However, feasibility of implementation depends on different site-specific conditions, technology selection and the valuation of carbon removal.
