In order to valorize this, the study illustrates how to do a step-wise assessment in order to design biorefinery set-ups based on their feedstock compatibility and region of implementation. This assessment tests the no agricultural waste concept, an agricultural system where all residues are utilized within a value chain, to elucidate whether the concept does indeed improve environmental performance across various regions, and if so, explores how various biorefinery concepts might be organized into various value chains to attain environmental benefits. Assessing alternatives in a regional context provided valuable information about the influence of different types of feedstock on environmental performance.Īlthough there is great opportunity, the bioeconomy is not a silver bullet in the quest to solve various environmental problems. Preference for the technology scenario producing the most energy was shown for all regions and scales, while producing bioplastic was less preferable since the value of the produced bioplastic plastic was not great enough to offset the resultant reduction in energy production. Multiple criteria decision analysis and internalized damage monetization were used to generate single scores for the assessments. Then, the environmental impact and economic potential of each technology when scaled up to the regional level, considering all of the region’s unique sustainably available feedstock, was investigated. First, sustainable feedstock availability for two European regions was quantified. Three technology variations for anaerobic digestion (AD) were assessed at two different scales (200 kW and 1 MW) and for two different regions. In this study, to achieve this goal of singling out an ideal technology for a given region, biotechnologies are assessed by a combination of techno-economic assessment (TEA) and territorial metabolism life cycle assessment (TM-LCA). Ideally, options leading to the highest environmental and economic gains can be singled out for any given region.
An efficient use of biomass resources is a key element of the bioeconomy.
