Assessment of seasonal variation of biogas potential from industrial residues and by-products

Anaerobic digestion technology (AD) for biogas production offers numerous benefits as it may not only recover the energy contained in the biomass but also contribute to a reduction of greenhouse gas emissions, nutrient recovery, prevention of nitrogen leakage into groundwater and prevention of the spread of harmful diseases through landfilling. Furthermore, low- value materials regarded as waste, from industrial processes, agriculture and other human activity are used for the production of higher-value products and thereby improving resource-efficiency. The expansion of the biogas production promotes the need for the assessment of the biogas potential of biomass, which is available for the biogas production and not in the competition with the other purposes. Residuals and by-products which occur during the industrial production have been recognised as the preferred replacement for the food or feed crops since they do not require agricultural land for its production. This work presents the approach for the assessment of biogas potential from industrial residues and by-products, by taking into consideration the seasonal variation of feedstock production. Here, the main focus is set on by-products which occur in sugar and wine industry. Statistical information, previous research and various reports were used for the estimation of seasonal variation. This approach was tested at the case study of seven wineries and one sugar refinery located in Osijek-Baranja county. The final results are presenting the spatial distribution and seasonal variation of the biogas potential from sugar beet pulp and wine pressings.
