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.

“…The evaluation of the exhaust gas released due to the combustion of sewage sludge in the FBSSIs for electricity generation with the ORC was discussed partly in only a few published papers in the open literature [33][34][35]. On the other hand, waste heat obtained from WWTP or MSWP integrated into an ORC was extensively studied [36][37][38][39][40].…”

This paper presents the design, evaluation, and optimization of an electricity generation system based on the two-stage organic Rankine cycle (TS-ORC), which utilizes the waste heat of an existing fluidized bed sewage sludge incineration (FBSSI) facility. The facility incinerates an average of 300 tons per day of sewage sludge with a dry matter content of 22%. After the drying process, the sewage sludge is burned in a fluidized bed combustor, and exhaust gas at a temperature of about 850-900ºC is released due to the combustion. The system provides the energy required to dry the sludge from this exhaust gas. In this study, a TS-ORC is designed to be coupled to the exhaust gas flowlines discharged to the atmosphere at two different points in the FBSSI plant. The exergy efficiency of the FBSSI facility is found to be 70.5%. Three different working fluids are selected to examine the variations of thermodynamic and thermoeconomic performance parameters of the designed TS-ORC system. The highest power generation in the TS-ORC system (183.40 kW) is achieved using R1234yf as working fluid. R1234yf is also the most expensive fluid for electricity generation among the other working fluids (10.57 $/h). The least electricity generation in the TS-ORC (142.70 kW) occurs at the thermoeconomically most affordable cost with R245fa (9.35 $/h).

In case three, the exhaust gas of the biogas engine-driven cogeneration, with the increased power output, using all the biogas produced, was considered, to produce WH in a wastewater treatment plant [30]. In case four, a cement production plant that is located in Gaziantep, Turkey, was studied, and the hot gas exhaust from the raw mill unit that is employed in the cement production process (State 1), was considered [31].…”

The heating of the buildings, together with domestic hot water generation, is responsible for half of the total generated heating energy, which consumes half of the final energy demand. Meanwhile, district heating systems are a powerful option to meet this demand, with their significant potential and the experience accumulated over many years. The work described here deals with the conventional and advanced exergy performance assessments of the district heating system, using four different waste heat sources by the exhaust gas potentials of the selected plants (municipal solid waste cogeneration, thermal power, wastewater treatment, and cement production), with the real-time data group based on numerical investigations. The simulated results based on conventional exergy analysis revealed that the priority should be given to heat exchanger (HE)-I, with exergy efficiency values from 0.39 to 0.58, followed by HE-II and the pump with those from 0.48 to 0.78 and from 0.81 to 0.82, respectively. On the other hand, the simulated results based on advanced exergy analysis indicated that the exergy destruction was mostly avoidable for the pump (78.32–78.56%) and mostly unavoidable for the heat exchangers (66.61–97.13%). Meanwhile, the exergy destruction was determined to be mainly originated from the component itself (endogenous), for the pump (97.50–99.45%) and heat exchangers (69.80–91.97%). When the real-time implementation was considered, the functional exergy efficiency of the entire system was obtained to be linearly and inversely proportional to the pipeline length and the average ambient temperature, respectively.
