“…This has led to an increased interest in biogas plants for the joint production of heat and electricity. Numerous studies have been conducted that prove the advantages of this technology (Kaur et al 2021;Bai et al 2022;Wang et al 2021;Caetano et al 2022;Rouhollahi et al 2020). In the construction of cogeneration plants using biogas for livestock farms, decisions related to the choice of a specific technology and the availability of raw material (animal waste) on a significant scale are of crucial importance (Ardebili 2020;Kozłowski et al 2019;Barozzi et al 2021;Pryshliak et al 2022;Doseva and Chakyrova 2019).…”

The introduction of increasingly strict rules related to the processing and storage of animal waste, the growing demand for energy and the creation of sustainable animal husbandry have led to an increased interest in the production of clean energy from animal waste. The production of biogas and its subsequent burning on the farm is among the most promising technologies. One of the possibilities for the utilization of biogas is through the use of small aggregates for the combined production of electricity and heat energy based on an internal combustion engine. Analysis of such facilities that have been put into operation show that alternative technologies using biogas as fuel are better than conventional options, both from an economic and an environmental point of view. In this sense, however, the introduction of such a technology into operation is always associated with a number of risks, since investments in new technologies are influenced by technical and economic uncertainty. When planning and preparing the plan for the construction of such a biogas facility, the investment costs, technical support and profitability of the project are essential. Introducing critical economic and technical parameters to inform the farmer of all possible investments, operational and unforeseen risks will allow him to accept the challenges and choose the best solution for his farm. In this publication, an analysis and assessment of the risk has been carried out based on the characteristics of the technology -the possible consequences of the risk are also presented. 124A risk matrix related to the specifics of the object and the technology is proposed, with the help of which, the type of risk is identified. Based on an analysis of the obtained results, a motivated proposal for reducing the risk is made.

“…Biogas is the most economical renewable fuel that is used in many countries. This fuel is used for cooking, cooling and heating, electricity generation, waste management, and mechanical power generation (Czekała et al, 2023;Caetano et al, 2022;Fazzino et al, 2021).…”

Biomass energy is a type of renewable energy and animal waste is one of the main resources for its production. Anaerobic digestion is a method for biological treatment of organic waste, which nowadays plays an important role in refining and reusing wet and degradable waste materials due to the production of environmentally friendly materials and energy recovery. The process of anaerobic digestion takes place in oxygen-free conditions inside reactors called anaerobic digesters and produces a substance called biogas. The purpose of this study is to investigate the effect of raw material type (cow and chicken manure) and the type of reactor (digester) on the biogas produced by measuring the amount of methane in the product. Three types of digester (metal, simple PVC and PVC with leachate rotation) with the same volume (10 Liter) were prepared. Equipment was installed on the digesters to measure the pH and volume of produced gas. The experiments were carried out in controlled temperature conditions (28–30 ºC) and in two stages. The first experiment was to load the digesters with cow excrement and the second experiment was to load the digesters with chicken excrement. In both experiments, the digesters were fed with 1.5 kg of animal manure and water with a ratio of 1:1. During a period of 60 days, the volume of biogas and methane produced was measured and recorded. The results showed that the amount of biogas produced from chicken waste is more than the amount obtained from cow waste. However, the amount of methane produced using cow excrement was more than that of chicken excrement. Also, the performance of PVC digester with leachate rotation was better than the other two digesters, which could be due to the mixing of raw materials in this type of digester.

“…Biomethane fuel obtained from biogas using a solid matrix of wood ash has been shown to be feasible for the purposes of injecting biomethane into the gas grid [4]. The feasibility of biogas as an alternative fuel to generate electricity via a Stirling engine, within the context of distribution electricity production, has been shown in the literature [5]. Fuel for some of the aforementioned systems could often be in the form of biogas, such as from agricultural wastes, manure, and domestic waste.…”

Purifying biogas can enhance the performance of distributed smart grid systems while potentially yielding clean feedstock for downstream usage such as steam reforming. Recently, a novel anion-pillared metal–organic framework (MOF) was reported in the literature that shows good capacity to separate acetylene from carbon dioxide. The present study assesses the usefulness of this adsorbent for separating a typical biogas mixture (consisting of methane, nitrogen, oxygen, hydrogen, carbon dioxide, and hydrogen sulphide) using a multiscale approach. This approach couples atomistic Monte Carlo simulations in the grand canonical ensemble with the batch equilibrium modelling of a pressure swing adsorption system. The metal–organic framework displays selectivity at low pressures for carbon dioxide and especially hydrogen sulphide. An analysis of adsorption isotherm models coupled with statistical distributions of surface–gas interaction energies determined that both CH4 and CO2 exhibited Langmuir-type adsorption, while H2S displayed Langmuir-type behaviour at low pressures, with increasing adsorption site heterogeneity at high pressures. Batch equilibrium modelling of a vacuum swing adsorption system to purify a CH4/CO2 feedstock demonstrated that such a system can be incorporated into a solar biogas reforming process since the target purity of 93–94 mol-% methane for incorporation into the process was readily achievable.
