“…Because of Ethiopia's rapid population expansion and growing living standards, food waste is typically produced at an ever-increasing pace from home, commercial, institutional, and industrial sources (Lin et al, 2019). Reusing this beneficial feedstock for energy recovery and municipal solid waste reduction looks like a reasonable concept because food waste makes about 40-50% of the weight of municipal solid waste and contains high moisture and biodegradable organics (Worasaen et al, 2017). For the treatment of food waste, numerous anaerobic techniques have been widely developed in different nations.…”

<p>The primary aim of this research is to identify the best anaerobic digestion process yield for generating biogas from mixed food waste in the combination of cow manure. For the biogas generation experiment, certain biodegradable domestic organic wastes gathered from restaurants, waste storage facilities, the fruit-and-vegetable market and manure from cows. Organic waste collection; 38g of mixed food waste, cow dung waste and its mixture collected from Yaaballo town. To match the digester's input size and to make digestion easier, all wastes were broken down into little (5 mm) pieces by using a mortar and pestle. Organic materials were kept in plastic bags till anaerobic digestion got started. Because high temperatures stimulated the growth of methanogenic bacteria in the digester, the findings from the research indicated that Mixed Food Waste and Cow Dung Waste produced the most biogas (44ml) at 45⁰C in a short retention period. The temperature, PH, and retention time all significantly (P0.05) affect the production of biogas, according to the ANOVA results. It is possible to combine organic materials with equal amounts of high and low C:N ratios to get the ideal C:N ratios for digester use. The pH stability and increased methanogenic activities achieved by changing the C:N ratio of organic waste to provide the greatest biogas generation in Mixed Food Waste and Cow Dung Waste. For the best yield, the combination of diverse organic waste and the effects of various parameters on biogas production should be thoroughly studied.</p>

BackgroundThe implementation of activities agriculture resulted in a large amount of wastewater and organic waste. In the past, Thailand has been using these to produce biogas to replace fossil fuels in the country. At present, biogas production has a residual amount due to no use in farms/factories. So, it to be released into the atmosphere. The government has a policy of biogas by the upgrade to produced biomethane for fuel vehicles but it is still just a prototype system. Therefore, if the government has targeted of the development biomethane in commercial plants, it is necessary to analyze the financial feasibility to an incentive of investors and plan for energy effective support. Including, people can use gas at a reasonable price and create a comprehensive energy source in sustainable agriculture.ResultsThe research evaluates the commercial investment potential of compressed biomethane gas plants based on upgrading biogas by water scrubber technology. The results identified biogas plants must have a digester volume of 2,000 m3 or more to produce compressed biomethane gas. Locations of 10 plants with the potential to establish compressed biomethane gas plants in Thailand. The capacity of compressed biomethane gas plants at 3, 6, 12 and 24 tons/day with no subsidy, subsidy 20% and 30% from the government. The plant should have a capacity of 12 tons/day or more in on subsidy from the government that there will be a financial possibility. The government should be subsidy at 30% in the plants of capacity at 3 tons/day for small plants can operate their businesses, subsidy 20% in the plants of capacity at 6 tons/day. In the part of plants more 12 tons/day which the government should be added measures such as Measures for low-interest loans, tax relief measures, etc. In addition, 10 locations will be expected to reduce greenhouse gas emissions by about 78,333 tCO2e/year. ConclusionThis study can be used to support decision-making on commercial investment in clean technology to promote the use of resources in agriculture for efficient transportation and support energy-efficient plans to provide an alternative sustainable fuel source to reduce global warming.

Background Biomethane is a clean fuel upgraded from biogas. It has similar properties to natural gas vehicle (NGV) and can be used as a substitute for fossil fuels in the transportation and industrial sectors. Currently, biomethane is not in widespread use as alternative energy because it depends on local biogas production. However, there are few replacement alternatives and the commercial system is only on a small scale. Therefore, the overall aim of this paper is to study the financial feasibility of local biogas aggregation for producing biomethane on various scales. The results of the study are expected to aid the decision-making of investors and governments in promoting the use of renewable and sustainable sources of energy. Methods Primary and secondary data are used in this research for descriptive and quantitative analysis, while net present value, internal rate of return, payback period, and cost per unit represent the financial instruments. The location and distance methods applied are Google Maps and Power BI software programs, based on biogas upgrading by water scrubbing. Results The results indicate that 10 potential biomethane production areas exist in Thailand, with a total biogas production capacity of 6,000 m3/day or more under gas pipeline conditions not exceeding 50 km. Compressed biomethane gas plants with a capacity of less than 6 tons/day should be funded by the government at 30% of the total investment for a payback period of 5–6 years. Plants producing more than 6 tons/day provide a good return on investment even without government funding. Conclusions While this study focuses solely on areas of Thailand, it is the researcher’s position that the integration of residual biogas plants provides greater benefit than flare, particularly in remote areas. The model proposed in this study can serve as a prototype for developing countries such as Malaysia, the Philippines, Latin America, etc. Furthermore, it can be used in developed countries committed to reducing greenhouse gas emissions in accordance with the Paris Agreement.
