The article analyses the types of waste generated in economy and the possibilities of their management, on the example of Poland. The main focus was on using selected types of waste for methane production. The impact of the decomposing mass of organic waste on the production of greenhouse gases was examined and various types of biogas plants operating in Poland were presented (biogas plants at landfills, biogas plants at sewage treatment plants, agricultural biogas plants). The article also presents the benefits for the economy from the use of methane from methane drainage. Unfortunately, in Poland, methane resources are used to a small extent. In the case of mines, landfills or sewage treatment plants it is related to high costs of constructing methane capture installations, which are not offset by revenues from sales of gas and green certificates. Although much more favourable blue certificates have been introduced for agricultural biogas plants, the obstacle standing in the way of their progress is the lack of local spatial development plans for the places designated for their construction.

The agricultural and food sector accounts for substantial volumes of organic waste (such as livestock excreta, meat offals) considered as onerous on the environment. The above decomposes formulating methane, carbon dioxide and hydrogen sulphide in anaerobic conditions. Methane produced in digester chambers of a biomass plant (called biogas) may be applied for the production of electricity and heat, powering of vehicles as well as injections into gas networks. Biogas is one of the renewable sources of energy. In the light of the EU's sustainable development and climate neutrality policies, increasing the share of renewable sources in overall energy consumption is a priority for the Member States. For this reason, the article examines one of the renewable energy sectors in Poland, which is agricultural biogas production. The main attention was focused on agricultural biogas plants. Most often used substrates for biogas production, the dependence of biogas plant location on the population living in particular regions (voivodships) and the development of agriculture in their territories were analysed. The main purpose of the article was to indicate the reasons for the failure of the agricultural biogas plant construction program in Poland. Literature and document analysis were performed, interviews with waste producers as well as owners of agricultural biogas plants were carried out, and SWOT analysis was prepared.

In the era of renewable energy development, one of the most important problems is the utilisation of residues of production of the so-called clean energy. In the case of biogas plants, the problem is the utilisation of waste after the anaerobic methane fermentation process of the organic substrate. One of the ways to use it is to produce organic and mineral fertilisers. However, the fertiliser plant may be exposed to a number of threats that may prevent its functioning. To avoid this, the factors that carry the risk need to be identified. The purpose of the article is to identify external risk factors for a fertiliser plant based on digestate. The following types of risk were identified as a result of the research: risk of supplying fertiliser components of inadequate quality; risk of non-compliance with deadlines for the delivery of raw materials or their total absence; risk of the presence of eggs of parasites and pathogenic bacteria in fertiliser; price risk; cyclical risk; risk of competition; currency, credit and interest rate risk.
