This paper deals with the possibility of using agricultural residues for the production of densified solid biofuels. The aim of the study is to evaluate energetic characteristics of plant residues that come from sea buckthorn production chain in the conditions of the Republic of Moldova. The biomass for investigations (branches obtained as a result of pruning sea buckthorn trees of the Cora variety) was collected from an experimental plantation established in 2014. The analyses carried out in the Laboratory of Solid Biofuels of the State Agrarian University of Moldova show that moisture content of the studied samples, estimated immediately after pruning, does not exceed 46%. Ash content varies within the limits of 0,49-1,94%, and the net calorific value is from 16,92 to 17,21 MJ/kg when the humidity equals to 10%. Based on the gained results, it has been proven that plant residues from sea buckthorn pruning can be used as a raw material for the production of densified solid biofuels with the qualitative characteristics that comply with European standards ENPlus 3.
