Fig. 4: Main processes and inputs accounted for during primary, secondary and end-of-life uses of harvested wood products (HWP) within consequential life cycle assessment boundaries.

Main processes arise during each stage of the value chain, including forest establishment (and associated land use change from grassland); wood processing (debarking, milling, wood panel and paper production from primary and secondary wood flows); storage of carbon in HWP (primary and secondary wood products); recycling and disposal of HWP (primary and secondary wood products), including incineration (with energy recovery) and landfill; bioenergy generation (with bioenergy carbon capture and storage (BECCS) in later years); substitution of fossil fuels for energy generation; substitution of mineral construction materials.
