The objective of this research was to evaluate the quality indices of the dry matter from agricultural residues - stems of Asteraceae species: Artemisia absinthium, Cynara cardunculus, Silphium integrifolium, Silphium perfoliatum, Solidago canadensis collected in the experimental plot of the NBGI Chişinău. It has been found that elemental composition of the collected stems dry matter was 41.36-50.00% carbon, 4.32-6.14% hydrogen, 0.62-1.37% nitrogen, 0.03-0.10% sulphur, 2.18-5.66% ash and gross calorific value varied from 18.2 to 19.0 MJ/kg dry matter. The dry biomass contained 461-545 g/kg cellulose, 180-320 g/kg hemicellulose, 85-112 g/kg acid detergent fibre and the estimated theoretical ethanol yield varied from 522 to 575 L/t organic dry matter and biomethane potential from 167 to 266 L/kg VS. The investigate agricultural residues have optimal concentration of structural carbohydrates and energy value, which make them suitable to be used as a part of a diverse mix for solid biofuel production and feedstock for cellulosic bioethanol as renewable energy.
