“…The dry matter parameter was tested using a dryer for the samples, at a temperature of 105 • C for a period of 24 h. For each measurement, the collected samples were homogenized. The determination of organic dry matter content was performed as normal, and the substrates, after the drying process, were placed in a muffle furnace for 3 h at 550 • C [31].…”

“…The composting process is an aerobic management method, during which the biological decomposition of organic matter takes place in the presence of oxygen in a wet and warm environment. The product of composting is compost, and the by-products are carbon dioxide, water and heat [31,51]. However, the condition is the use of appropriate technology that guarantees the maintenance of the process parameters, such as proper temperature, giving microorganisms optimal conditions for the process.…”

The aim of this study was to conduct a comprehensive economic and energy efficiency analysis of selected digestate management methods, considering their implications on operational costs and resource management. To achieve this aim, the study focuses on a comparative assessment of different digestate management methods, including land application, mechanical separation, the composting process and pellet production. The economic analysis involves the evaluation of the initial investment, operational expenses, and potential revenue streams associated with each method. The most economical and popular solution of digestate management is direct use as fertilizer, with total costs of 1.98 EUR·Mg−1. All of the other methods involve higher digestate management costs, respectively; for separation it is 2.42 EUR·Mg−1, for composting it is 2.81 EUR·Mg−1. The process that is the most energy-intensive, but profitable, is the production of pellets from digestate, resulting in profits of 334,926 EUR·year−1. It should be noted that the other analyzed methods of digestate management also bring many environmental benefits, affecting sustainability and reducing emissions. The results of this research will contribute unique data on the feasibility of managing the digestate and its fractions. The calculations of economic and energy values for different strategies will allow for the optimization of the overall performance of the biogas plant, thus promoting a circular economy.

“…Air is pumped into the containers for the correct process. By composting in a closed space, it is possible to carry out complete control of the extracted gases (Graça et al, 2021;Bojarski et al, 2023). The most commercially available container composting technologies provide biofilters which allow almost complete deodorisation of the resulting odours.…”

The management of biodegradable waste from various sectors of economy is an essential element in terms of environmental protection. The paper discusses issues related to the possibility of bio-waste treatment using anaerobic digestion technologies and composting processes, highlighting the conditions for the processes and their advantages and disadvantages. The challenges of overproduction of bio-waste faced by highly developed countries around the world are also presented. Research showed that the anaerobic digestion of this waste combines both biofuel production and a circular economy. The popularity of this method is linked, among others to a low cost of raw materials and wide range of possible uses for biogas (i.e. electricity, heat, or biomethane). In addition, an alternative bio-waste management option, compost production, was discussed. The study aimed to compare anaerobic and aerobic bio-waste management processes.
