“…However, the rescue plan for existing installations, as well as planned investments, is to combine the use of manure and low cost industrial substrates with high biogas yields [15]. The national energy and climate plan for the years 2021-2030 [16] indicates renewable energy development directions in Poland, considering the possibility of producing annually 7.8 billion m 3 of biogas from agricultural sources.…”

Bioenergy production from animal waste can be a key driver to achieving bio-economy goals. Developing a bio-economy sector could help to create opportunities for a circular system where not only people and the planet will be benefited, but it will also provide economic profitability to farmers, especially in the post-Covid period. To this end, manure production, its nutrient content, and bioenergy potential were estimated, along with their spatial distribution in the Lubelskie province, Poland. Farm-level data were processed and aggregated at the municipality level. Material balance equations were used to calculate the theoretical potential of livestock manure and bioenergy for different use scenarios: (1) Baseline (BC): direct manure application to land, which was compared against (2) Anaerobic Digestion (AD): anaerobic digestion to biogas with digestate returned to the fields (3) AD + Separation (AD + Sep): mechanical separation followed by anaerobic digestion, and (4) Surplus + AD: surplus manure (after application to the fields) is sent to anaerobic digestion. Manure, biogas, electricity, and thermal energy production of the AD scenario were estimated to be 7.5 Mt y−1, 378 Mm3 y−1, 907 GWe y−1, and 997.8 GWth y−1, respectively. The scenario, including mechanical separation followed by anaerobic digestion (AD + Sep), contributed to avoiding emissions to the largest extent (1 Mt CO2 eq), whereas AD outperformed the others in avoiding costs of fertilization. According to the estimated potential and the environmental cost-effectiveness of AD, new plants can be established that will recycle manure through bioenergy production, and, subsequently, the digestate can be applied as organic fertilizer, closing the nutrients cycle.

“…As demonstrated by Kozłowski [25], in Poland, over 112 million Mg of manure is produced annually, and only less than 1% is used to produce biogas. This is a surprisingly small amount, as the digestate is quite often used in crops, mainly due to its rich elemental composition, i.e., nitrogen, potassium and phosphorus [26,27]. It has been proven in many cultivation studies that the addition of digestate to the soil has a positive effect on the quality of crops [26,[28][29][30][31][32].…”

The aim of the study is to draw attention to the fact that reducing methane and nitrous oxide emissions as a result of traditional manure storage for several months in a pile is not only a non-ecological solution, but also unprofitable. A solution that combines both aspects—environmental and financial—is the use of manure as a substrate for a biogas plant, but immediately—directly after its removal from the dairy barn. As part of the case study, the energy and economic balance of a model farm with dairy farming for the scenario without biogas plant and with a biogas plant using manure as the main substrate in methane fermentation processes was also performed. Research data on the average emission of ammonia and nitrous oxide from 1 Mg of stored manure as well as the results of laboratory tests on the yield of biogas from dairy cows manure were obtained on the basis of samples taken from the farm being a case study. The use of a biogas installation would allow the emission of carbon dioxide equivalent to be reduced by up to 100 Mg per year. In addition, it has been shown that the estimated payback period for biogas installations is less than 5 years, and with the current trend of increasing energy prices, it may be even shorter—up to 4 years.

“…Selected municipal waste, such as household kitchen waste, restaurant waste and expired food, can be successfully used as substrates in biogas plants. The biogas obtained from them has a high methane content [20]. Contrary to other fractions, biodegradable waste of food origin is characterized by biochemical diversity (heterogeneity) and therefore it is a good material for anaerobic treatment.…”

Changes in the approach to using waste as resources will be a necessity in the coming years. It is due to the transformation of the linear economy into a circular model and many regulations concerning waste management in the European Union countries. The article deals with the important issues of segregation and management of biodegradable waste, which are still unused energy potential. The aim of the study was to investigate the amount of this fraction of waste generated by sample households as well as the problems and barriers related to their storage and collection. The article takes into account the economic, environmental and social conditions that constitute the basis of sustainable development and are very significant for the idea of the circular economy. The minimizing and proper management of the fraction of municipal and biodegradable waste could achieve a greater economic benefits with simultaneous benefits for the environment, protecting its components and human health.
