Dependence of AC on life cycle inputs to produce 1 ton of biochar. Note: FPP – firewood is intended for the pyrolysis process; BPR – bricks are intended to produce reactors, which accounted for 80% of the total weight, with amortization for 5 years; MPR – metal is intended to produce reactors, with amortization for 5 years; MPT – metal is intended to produce troughs, with amortization for 1.5 years; FT – fuel is for techniques; TS – transportation of stumps to the processing site (15–20 km radius); SBP – stumps are intended for biochar production; MTP – metal for techniques production, with amortization for 20 years; EP – electricity for processes.
