| Popis: | In order to minimize the environmental impacts of growing population, progressive exploitation of fossil resources and negative consequences of climate change the politically intended goal is to successively transform our primarily oil-based into a bio-based economy. Hence, one goal is to significantly reduce the utilization of fossil resources by increasing the use of renewable energy and resources (i.e. biomass) and the efficiency of their conversion processes. Including existing technologies into the development of future concepts could accelerate the transition to a bio-economy. As one solution integrated biorefinery concepts based on agricultural biogas plants are discussed, which convert biomass with minimal energy consumption to a multitude of products without generating waste. However, they still have huge potential in terms of increased biomass utilization. In that context, catch crops offer interesting opportunities as a substrate for those biorefineries, since they support soil regeneration while generating additional products for the bio-economy without increasing land use. In this study a selection of significant indicators was chosen in order to determine the environmental effectivity and economic efficiency of these biorefinery concepts by a systematic assessment of possible process schemes. Thus within this study the usability of the chosen indicators and the potential of catch crops in advanced biorefineries is assessed. |
