To design biogas plants, it is necessary to have accurate data about the properties and biogas productivity of the available substrates. Reference data should not be used because the performance of the same substrate can vary significantly. In this research,chicken, horse, sheep and rabbit manure from one of the farms inthe Belgorod region of Russia were analyzed, and the parameters of a biogas station for the processing of this raw material were calculated.The biogas yield of the substrates was determined using the Hohenheim Biogas Yield Test. It was found that the specific biogas yield from the droppings of broilers, laying hens, rabbits, sheep, and horses, and from corn silage were, respectively, 456, 363, 390, 189, 116 and 618 ml/g оDM. The methane content in the biogas was 58.00, 58.50, 57.00, 62.00, 65.00 and 53.60%, respectively. In most cases, the obtained results differed significantly from the data presented in publications of other researchers and reference books.The biogas plant parameter calculations were made according to generally accepted equations, taking into account the characteristics of the studied substrates. Based on the results, it can be concluded that to dispose of the animal excrement of this farm, it is necessary to build a biogas plant with a bioreactor of volume 102.2 m3 and an engine with a power of 12 to 31 kW. The planned output of electric and thermal energy would be 246.19 and 410.27 kWh/day, respectively.

Biogas plants may support the transformation towards renewable-based and integrated energy systems by providing dispatchable co-generation as well as opportunities for biogas upgrading or power-to-X conversion. In this paper, a simulation model that comprises the main dynamics of the internal processes of a biogas plant is developed. Based on first-order kinetics of the anaerobic digestion process, the biogas production of an input feeding schedule of raw material can be estimated. The output of the plant in terms of electrical and thermal energy is validated against empirical data from a 3-MW biogas plant on the Danish island of Bornholm. The results show that the model provides an accurate representation of the processes within a biogas plant. The paper further provides insights on the functioning of the biogas plant on Bornholm as well as discusses upgrading potentials of biogas to biomethane at the plant from an energy perspective.

The study aimed to assess the most efficient solution of raw material management in selected biogas plants into the concept of circular economy and evaluate the most efficient solution of raw material management in selected biogas plants due to the quality and quantity of the feed and the final product obtained, which is biogas, as well at the closed circulation (circular economy). The study evaluated two agricultural biogas plants on a real scale and one at the sewage treatment plant (in real scale) in northeastern Poland. A year-long study showed that in technical terms, the best work efficiency is achieved by agricultural biogas plants processing: silage, manure, apple pomace, potato pulp (biogas plant No. 1), followed by biogas plant No. 3 processing chicken manure, decoction, cattle manure, poultry slaughterhouse waste (sewage sludge, flotate, feathers), and finally, the lowest efficiency biogas plant was No. 2, the sewage treatment plant, which stabilized sewage sludge in the methane fermentation process. Moreover, based on the results, it was found that agricultural biogas gives the best efficiency in energy production from 1 ton of feed.

This research aims to give an overview on how to improve the biogas yeild in Balinese digester plants using various co-substrates which are available in Bali. A series testing on the digestibility of substrates were set up either in the field or in the biogas laboratory. In-field analyses like testing the CO2-content and taking samples from digested manure were undertaken. Analyses such as dry matter (DM) and organic dry matter (oDM) determination, pH measurement and FOS/TAC were handled in the biogas laboratory. The huge number of different fruits in Bali gives a good opportunity to use their wastes like Durian hulls and Banana peelings, which can not be used anymore, as co-substrates in biogas plants. The results of these investigations allow to estimate the additional biogas yield, when adding co-substrates to a cow manure biogas plant.

Growing and utilizing bioenergy crops as feeding substrates in biogas plants may aid the development of the biogas sector in Ukraine. Therefore, research was done on potential methane yields from 22 high-yield varieties of 7 different crops grown in Ukraine for their biogas production suitability. Annual crops (maize, soybean, sweet sorghum and sorghum hybrids) and perennials (miscanthus, paulownia and switchgrass) harvested at three different harvesting times (H1, H2 and H3) related to specific stages of phenological development were investigated. The perennial crops studied were from different vegetation years. The samples were analysed in Ukraine on their dry matter- and volatile solids contents, dry matter yield (DMY) and crop nitrogen (N) uptake. The 55 °C -dried samples were delivered to Germany for their analysis with the Hohenheim Biogas Yield Test (HBT) on their specific methane yield (SMY). Based on DMY and SMY, the areal methane yields (AMY) were calculated. The highest SMY and AMY were found for maize, sweet sorghum and miscanthus. The highest average SMY of 0.35 ± 0.03 m3CH4 kgVS−1 was found for maize samples harvested at H2. Miscanthus “Giganteus” from the 8th vegetation year harvested at H1 has shown the highest AMY of 7404.50 ± 199.00 m3CH4 ha−1.

High precision of measurement of methane potential is important for the economic operation of biogas plants in the future. The biochemical methane potential (BMP) test based on the VDI 4630 protocol is the state-of-the-art method to determine the methane potential in Germany. The coefficient of variation (CV) of methane yield was >10% in several previous inter-laboratory tests. The aim of this work was to investigate the effects of inoculum and the digestion system on the measurement variability. Methane yield and methane percentage of five substrates were investigated in a Hohenheim biogas yield test (D-HBT) by using five inocula, which were used several times in inter- laboratory tests. The same substrates and inocula were also tested in other digestion systems. To control the quality of the inocula, the effect of adding trace elements (TE) and the microbial community was investigated. Adding TE had no influence for the selected, well- supplied inocula and the community composition depended on the source of the inocula. The CV of the specific methane yield was <4.8% by using different inocula in one D-HBT (D-HBT1) and <12.8% by using different digestion systems compared to D-HBT1. Incubation time between 7 and 14 days resulted in a deviation in CV of <4.8%.

Production of Bio gas from cattle waste and other biomass is now considered as one of the majorroutes to obtain gaseous fuel for sustainable development. In tropical countries like Indiathousands of rural families in villages are using 3 to 5 M3 biogas plants to suffice their dailycooking fuel need. All these plants are run on cattle waste. Since these plants are operated atambient temperatures, effect of temperature variation affects daily gas yield. The effect becomesvery prominent during winter season. In general about 50-60% reduction in daily biogas yield isobserved when ambient temperature is around l 5°C as compared to that produced at around 30-350C. A low cost and simple to operate technique to enhance biogas yield from the biogas plantduring winter season shall help to get optimum biogas yield from these plants during the winterseason. We thought of a simple technique of filtering the digested effluent slurry of biogas plantthrough a triple layer muslin cloth to obtain a filtrate, hence-forth called as clarified digestedslurry (CDS), rich in cell mass and then adding it back to the biogas plant along with the influentslurry. Experiments were carried out on 25 L capacity cattle dung biogas plant operated at 15°Cto see effect of recirculation of CDS. Addition of 25 and 40% v/v CDS in daily influent resultedin 15% and 37% increase in daily biogas yield. Recirculation of 40% v/v CDS supplementedwith Diammonium phosphate(DAP) increased the biogas yield by 75% v/v. In anotherexperiment use of clarified rumen fluid (CRF) to prepare influent slurry and added exclusivelyfor one day enhanced the daily biogas yield by 70% v/v for a period of two months. Popular dailywears in India called cotton dhoti or cotton sari can be used for the filtration of the slurry.

In the biogas plants, organic material is converted to biogas under anaerobic conditions through physical and biochemical processes. From supply of the raw material to the arrival of the products to customers, there are serial processes which should be sufficiently monitored for optimizing the efficiency of the whole process. In particular, the anaerobic digestion process, which consists of sequential complex biological reactions, requires improved monitoring to prevent inhibition. Conventional implemented methods at the biogas plants are not adequate for monitoring the operational parameters and finding the correlation between them. As Artificial Intelligence has been integrated in different areas of life, the integration of it into the biogas production process will be inevitable for the future of the biogas plant operation. This review paper first examines the need for monitoring at the biogas plants with giving details about the process and process monitoring as well. In the following sections, the current situation of implementations of Artificial Intelligence in the biogas plant operation and in the similar industries will be represented. Moreover, considering that all the information gathered from literature and operational needs, an implementation model will be presented.

The transition of livestock production to industrial processes and the concentration of animals associated with this process on large farms and complexes has caused a sharp increase in the volume of manure that must be disposed of without pollution. One of the ways of processing organic waste (biomass) is its anaerobic digestion in biogas plants through the vital activity of microorganisms (methanogenesis).Biogas obtained using microbiological processing of biomass can be used as a raw material for heat and electric energy. Annually, 0.17% of the total livestock manure produced at Russian agricultural enterprisesis used for biogas production.The main component of a biogas plant is a manure fermentation reactor, the required volume of which is determined by the daily output of manure from the livestock farm, the temperature and the hydraulic retention time of treatment. This research explored thermal energy consumption of biogas plants, using the example of a biogas plant of a modular design that depended on the average annual outdoor temperature. Based on the calculations, the thermophilic mode was found to be more energy-efficient than the mesophilic one; thus, with the thermophilic mode, the specific energy consumption needed for the plant was lower at the average annual outdoor temperatures of all the constituent entities of the Russian Federation. At the same time, the specific biogas yield in the thermophilic regime was 20-50%higher than in the mesophilic regime.

The main trend in energy development is to increase energy efficiency by reducing the use of limited natural resources, the spread of renewable energy, and reducing the negative impact on the environment. An effective response to these challenges is the use of biogas plants that produce clean energy and solve the environmental problems of waste disposal and recycling. The purpose of the article is to assess the economic efficiency of replacing district gas supply with autonomous biogas plants in public utilities. A hypothesis has been put forward that the feasibility of using such technologies depends on climatic features and the specific provisions of state regulation of prices and gas consumption rates. A cost approach was applied that assesses the overall structure of equipment costs, as well as a comparative assessment method according to the principle “with / without a biogas plant”, and a scenario analysis, the criterion of which is the size of the family owning the plant. An auxiliary method for forecasting retail and economically justified prices for natural gas for the population was used. The object of calculations is the “HomeBiogas” installation intended for home use. Three Russian cities were chosen as territorial subjects: Yekaterinburg, Irkutsk and Krasnodar. The cities which differ significantly in their natural characteristics and approaches to the formation of retail gas prices. It has been proved that although the average monthly temperatures differ significantly in the cities considered, none of them has a constant temperature exceeding the required standard value of 17°C. In each case, the initial capital investment is driven up by the cost of installing additional insulation and heating systems. This equalizes the costs of warmer and colder areas. Therefore, the climatic features of cities are not significant and do not affect the economic efficiency of using a biogas plant. In turn, state regulation of prices and norms of gas consumption by the population is of decisive importance. The findings are of theoretical and practical importance. The methodology can be applied to assess the efficiency of using biogas plants in industry and gasification projects in the remote areas of Russia.
