“…Biogas plants should be built from the home level to the industrial level. They enable people to generate energy in the form of electricity, allowing them to use stoves for cooking purposes (Manesh et al, 2020;Czekała 2022;Syahri et al, 2022).…”

Green electricity generation from biogas of cattle manure: An assessment of potential and feasibility in Pakistan

In several countries, organic or municipal solid wastes, such as cattle and buffalo manure, have become a serious political and environmental issue owing to organic waste incineration and garbage disposal. To overcome this problem, biogas production from manure, a green treatment that both contributes to the availability of sustainable energy and assists in reducing global warming, was considered. The current study was conducted on the generation of green electricity using cattle and buffalo manure in Pakistan. In 2021, Pakistan has generated 102.742-terawatt hour (TWh) of electricity collectively; biogas share in total production accounted for only 0.98%, which is approximately 1 TWh. Unfortunately, most of the electricity was generated from nonrenewable energy sources. One large animal produces 9–10 kg of manure per day. A system for manure collection can be developed; 30% of total manure produced every day by cattle and buffalo can be collected. Such a type of system is already used for the collection of poultry manure. Pakistan has been blessed with almost 42.4 million buffaloes and 51.5 million cattle. The annual collection of manure from cattle and buffalo at the rate of 30% will be 92.53 million tons. From this manure, approximately 4.63 billion m3 of biogas can be produced and 70% can be collected, which will be 3.24 billion m3. Thus, Pakistan has the potential of generating 19.79 TWh of electricity per day from cattle and buffalo manure. Biogas has the potential to generate over 20% of Pakistan’s total electricity. At the farm level, 100 cattle ranches with 60% collected manure can create roughly 57% of their total consumed electricity. Slurry, a byproduct of anaerobic digestion, can be used as a biofertilizer in fields. It is possible to use cattle manure to make biogas, which is “made by fermentation of organic waste in the absence of oxygen.” It aids in the reduction of fossil fuel dependency, solid waste management, and air pollution control by lowering greenhouse gas emissions. Biogas contributes to the three pillars of sustainable development: economic, environmental, and social development. Biogas contributes significantly to the SDGs and other aspects of sustainable development.

“…These changes are driven internationally through widely shared initiatives among countries, such as the Paris Agreement of the United Nations [1], whose goals set for 2030 the achievement of a complete supply of energy from renewable sources at a global level; and the European Green Deal [2], of the European Union, whose objectives aim for 2050 to reduce global warming. These agreements fall within the more general framework of sustainability, defined by the "2030 Agenda for Sustainable Development" [3], made up of 17 objectives, the so-called SDGs, that concern many thematic issues in addition to issues related to energy sustainability.…”

Blockchain technology finds application in multiple sectors, including renewable energy. Numerous blockchain-based applications aim to provide support in the production, management, distribution, and consumption of green energy. The benefits offered are not only technological but also social, environmental, and economic. The purpose of this study is to examine how the application of blockchain in the energy industry may affect the achievement of the Sustainable Development Goals (SDGs). This study is composed of two parts. The first part concerns the identification and analysis of the most relevant categories of blockchain applications in the energy sector and their ability to contribute to the achievement of the SDGs. A knowledge base, comprising scientific articles, gray literature, and real-world applications, has been created and analyzed. With a keyword-based approach, each application was associated with one or more SDGs. In the second part, the Sustainability Awareness Framework (SuSAF) was used to examine the findings of the first part of the study and discuss them in terms of five dimensions of sustainability. Finally, potential risks associated with the use of blockchain in the energy sector are also covered. Results reveal that tracking energy production and consumption and renewable energy communities are the applications that have the most beneficial effects, and that the benefits linked to blockchain adoption go beyond the energy sector to include the environment, the economy, industry, infrastructure, smart cities, and society.

“…There are various sources of bio-fuels such as cow dung, municipal waste, agricultural waste, plant material, sewage, green waste and food waste; among them, cow dung is the most common and available source of biogas. Basically, biogas is a mixture of methane, carbon dioxide and hydrogen sulphide and it is used as a renewable energy source [8] and is produced by anaerobic digestion [9]. Biogas production from cow dung is very useful because the effluent after digestion can be used as a natural fertilizer and it is also economic [10].…”

Biogas is an alternative and eco-friendly renewable power source and biogas effluent is used as a bio-fertilizer. In this research, the kinetic of biogas formation was studied and also the acceptance of biogas effluent as a bio-fertilizer was evaluated. 8000 g of cow dung and 600 ml of inoculum were fed to the digester. The volume of biogas production was observed for 50 days by using Orsat Apparatus and gas chromatography was used to analyze the gas. From the data, it was found that the formation of methane gas didn’t depend upon the concentration of cow-dung hydrocarbon and it followed the mechanism of the zero-order reaction. On the other hand, the elementary analysis of biogas effluent by AAS ensured the property of effluent as a bio-fertilizer. Utilization of Miscanthus fuscus with E. coli and S. aureus ensured a higher degree of biodegradation.
