Abstract

Bioconversion of wheat straw to ethanol is becoming an attractive alternative to ethanol production from conventional grain crops, especially with wheat straw being a low commercial value, high volume agricultural by-product and grain prices continuously increasing. Similarly, using wheat straw as energy source in the ethanol biorefinery has become a subject of interest in recent years. In this light, the aim of present work is to compare ethanol production from wheat grain and wheat straw for commercial scale plants. Using same configuration for the two feedstocks, change in ethanol and by-products’ outputs is simulated. The simulated biorefinery is based upon the established technologies within the bioethanol industry. In the two models same by-products are produced, namely: dried distillers grain solubles (DDGS), acetic acid, glycerol and furfural. Results show that 20% less ethanol is produced per ton for wheat stalk than when wheat grain is used.
