Název v původním jazyce

Energy balance of briquettes made of hemp (Cannabis sativa L.) cultivars (Ferimon, Bialobrzeskie) from autumn harvest to produce heat for household use

Popis výsledku v původním jazyce

This paper discusses energy balance and energy efficiency of briquettes made of different hemp (Cannabis sativa) cultivars. Harvest samples were subjected to experiments, during which moisture content (MC) and gross calorific value (GCV) were measured, according to which dry matter content (DM), biomass yield (BY) and net calorific value (NCV) were determined. An integral part of the energy balance determination was consideration and calculation of energy inputs. The energy expenditures for hemp were calculated including direct energy inputs by fuels and human labour and indirect energy inputs in fertilizers, seeds and energy embedded in machines. Regardless higher net energy yield for Ferimon cultivar compared with Bialobrzeskie, it was found that thedifference between their Energy Return On Energy Invested (EROEI) is not significant.
