Biochar has gained significant interest in the agroforestry sector, mainly because of its ability to improve soil quality and sequester carbon in the atmosphere. Among the feedstocks of possible use for biochar production is biomass, understood as products and residues of plant origin from agriculture and forestry. The quality of the biomass used for biochar production is important because the physicochemical characteristics of the final product depend on it. This review examines the use of biochar produced from forest wastes and its impact on agriculture, forest ecosystems and the environment in general. This work demonstrates that the use of biochar not only improves agricultural productivity and production, but also that the sustainable management of the environment and forests and contributes to forest fire risk mitigation. The authors, examining the physico-chemical properties of biochar produced by forest waste, noted that the most critical variable is the process (pyrolysis temperature, residence time and heating rate), but the type of biomass used as a raw material and the forest species used also have a significant impact in determining the characteristics of the final product.
