Abstract:

Conversion of biomasses to energy, food, feed and chemical building blocks for
further usage become increasingly important. Educations and research within biorefinery and
especially bioenergy have become popular and are offered at most universities in Europe.
Bioenergy is a very wide scientific area however, and we must educate students that possess the
qualifications to bring the industry and research forward. We must not just educate students that
know some general elements but students that really can go into the depth. Universities should
specialise and seek partners to complement educations and research areas.

Abstract:

Demand for local and renewable energy source materials is accelerating the search for new crops for energy production. Goat’s rue or galega (Galega Orientalis Lam.) is known as a long-living and well-adapted rhizomatious legume used mainly for production of high quality forage. Thanks to its strong stem and nitrogen-fixing bacteria, an economically produced and harvested yield is feasible. As an energy source, its yield can be used in an alternative manner. In this paper estimated usage is based on a combination: direct burning of dry material (spring harvest) and ensilaging of summer harvest. Therefore the crop produces 2 yields and gives the best estimated yield. Calculations for production costs are made for pure crop and mixed grasses, since these mixes are most productive. Hauling to the usage site and costs related to material processing are not considered. Results show that establishing of the crop for pure stand and mix with grasses will cost 467.88 and 487.06 € ha-1, yearly costs are 378.56 and 421.81 € ha-1 respectively, crop finishing adds extra 111.38 € ha-1 in both cases.
