Spelt (Triticum Spelta L.) - energy production from agricultural residues

Spelt is one of the oldest crops. It originates from Asia. In Europe spelt has been was very important cereal during the Bronze Age and the Middle Ages. After the processing grains for food, biomass lags as a by-product or waste. Rising fossil fuel prices and increasing concerns about climate change are creating a growing demand for new sources of raw material for biomass combustion for sustainable heat production. In recent years studies have shown the positive effects of the use of agricultural residues for energy production. Grains of Spelt are processed into various purposes, while the chaff, glumes and stems remain as a by-product. Therefore, it is important to carry out research in order to determine nutritional characteristics of grain and energy characteristics of chaff, glumes and stems. This paper examined the two Spelt varieties: Bc Vigor and Ostro. Collected and homogenized samples were analysed by the energy characteristics: high (HHV) and lower (LHV) heating values of chaff, glumes and stems were determined by standard methods. The results obtained in this research showed that, after the use of grain for food, chaff, glumes and stems are representing by-product but also it is high-quality raw material for energy production because of the high calorific values.
