Biowaste recycling in Upper Austria - evaluation of the current situation and possibilities for optimization and holistic recycling

The aim of the project is to compare variants for biowaste recycling and biogas utilization in order to optimize the use of renewable energy sources and quality composts for soil improvement. The scope of the study includes the generation, collection, recycling and utilization of biogenic waste (i.e. organic waste bin material, green waste, commercial kitchen waste and biogenic waste from the processing of agricultural products and food processing) in the province of Upper Austria. In the course of the proposed project, 1) the development or adaptation of eco-inventories that map relevant processes for waste collection, waste utilization, type and use of compost and biogas and transports of biogenic waste as well as compost and digestate on the basis of specialist literature, projects at ABF-BOKU and available process data sets, 2) the preparation of a life cycle inventory (or material flow analysis) for biogenic waste in Upper Austria on the basis of data provided by the client. material flow analysis) for biogenic waste in Upper Austria on the basis of data to be provided by the client on waste generation and composition, plant capacities, geographical location and catchment areas of existing plants, type of use of compost and biogas by region and catchment areas and transports of biogenic waste and compost (if necessary by means of estimates), 3) the definition and calculation of up to four process variants for future biowaste recycling and biogas use in coordination with the client and 4) the overall consideration of the possible optimization as a synthesis by means of sensitivity analyses.
