Nowadays, research on the use of pyrolysis products in the broadly understood economy is widely conducted in the world. This publication presents the results of research on the use of biochar primarily as a material for use in agriculture and environmental protection. In particular, its use to improve soil properties and as a component of organic fertilisers or composts, as well as an ingredient for animal bedding in livestock buildings or an additive for silage is discussed. In addition, the possibilities of using biochar in the energy sector as a solid fuel and in the broader field of environmental protection for remediation of contaminated land, for carbon sequestration and as a raw material for the production of activated carbons are discussed.
