The main objective of this work is to develop an economically viable process for producing papermaking fibres of adequate quality and generating energy from wheat straw. Wheat straw was selected as the raw material since wheat is cultivated and available worldwide (Curtis 2002) and only a minor part of the straw is used for energy production or animal feed. One of the primary aims in this work is to find ways to store the raw material chemically between the harvesting periods and examine the effects on pulping and pulp properties (Paper IV). In addition, the aim of this work is. | Dissertation VTT PUBLICATIONS 767 Anja Leponiemi Fibres and energy from wheat straw by simple practice VTT VTT PUBLICATIONS 767 Fibres and energy from wheat straw by simple practice Anja Leponiemi Doctoral dissertation for the degree of Doctor of Science in Technology to be presented with due permission of the School of Chemical Technology for public examination and debate in Puu2 Auditorium at Aalto University School of Chemical Technology Espoo Finland on the 5th of August 2011 at 12 noon. .
