Abstract
During testing, the possibility of using hemp biomass for energy purposes was assessed. The criteria assessed were the physical and chemical properties of hemp biomass, as well as the combustion process of straw and briquettes made of it in a low-power boiler. The results were made and compared with currently applicable standards. Technical and chemical properties of hemp biomass are comparable with the best plants used for energy purposes. Studies have also shown the susceptibility of hemp biomass compaction. However, large emissions recorded during the combustion of the tested forms of biofuels from hemp straw in light of applicable standards disqualify this fuel for use in grate-type heating devices with air fed under the grate. It would be advisable to carry out research on the total costs of pellet production and their use in heating devices with a retort burner, while taking into account this biofuel’s ashes’ susceptibility of sintering.

This Act indicates that the cultivation of hemp can only be carried out for the needs of the textile, chemical, cellulose, paper, food and cosmetics, pharmaceutical, building materials and seed industries
Summary
Hemp (Cannabis sativa L.) is grown for various purposes of using the fibre, chaff and seeds.It is one of the oldest non-food crops in the world. It is important that hemp biomass is processed into a number of hemp-derived products, including oil, essential oils or CBD (cannabidiol) substances, building material and biofuel, thereby producing many components that have been of great interest to people lately. Properties of this plant have made it an excellent raw material for the development of multi-output systems through gradual distribution of biomass into several useful components. This feature is ahead of many other industrial crops, from which only one type of raw material is usually extracted [2,5]
