Biogas Yield from Untraditional Energy Crops in Latvia

V. Dubrovskis, Adamovič & I. Plume
Suitability of usage of 2 amaranth cultivars and greater burdock (Arctium lappa L) for biogas production in Latvia was investigated. Cultivars ‘Raudonukai’ (Amaranthus cruentus L.) and ‘Geltonukai' (Amaranthus hybridus L) of family Amaranthaceae were grown in small plots for investigation purposes. Amarant silage and greater burdock green biomass samples were mixed with inoculums and investigated for biogas production in 5 l digesters, operated in batch mode at temperature 38±1.0°C. Investigated biogas yield per unit of...
