agricultural biogas plants; pairwise comparison; DEMATEL method
Agricultural biogas plants serve as both a renewable energy source and a means of biodegradable waste disposal in the agriculture and food industry. However, the development of such plants in Poland has been hindered by several factors including technology, substrates, energy policy, profitability, population density, and spatial arrangement. Through a pairwise comparison analysis using the DEMATEL method, it was determined that population density and the lack of local spatial development plans are the most influential factors. Improvements can be made by implementing spatial plans throughout each commune and locating biogas plants near livestock farms and agri-food processing plants.
Agricultural biogas plants are a renewable source of energy and at the same time enable the disposal of biodegradable waste generated in agriculture and the food industry. In Poland, a program aimed at constructing agricultural biogas plants has been in operation since 2010 with the goal of producing 1.7 billion Nm3 of biogas, which has not been achieved. Factors that could influence the development of this energy source were identified based on a register of agricultural biogas producers from the National Agriculture Support Center and data from the Energy Regulatory Office. These factors are technology, substrates, state energy policy, profitability, population density in the commune and the spatial arrangement of the commune resulting from spatial development plans. A pairwise comparison analysis using the DEMATEL method was conducted for these factors. It allowed us to conclude that they are population density and the lack of local spatial development plans in most rural areas. The situation may be improved by the obligation to develop such plans for the entire area of each commune and by locating biogas plants near livestock farms and agri-food processing plants. The selected DEMATEL method is mature and comprehensively verified. It enables research to be carried out in other contexts, taking into account the correlations between factors. It is a universal method, and after collecting expert opinions, research can be expanded. The obtained results of the analysis will allow for further research by collecting the opinions of experts such as biogas plant users, local communities, local government officials and other stakeholders. In addition, further analysis of key factors will be carried out using the DEMATEL method for several scenarios. The PESTEL method will be used to identify key factors.
