The framework of the methodology presented in this study is an effort to integrate and optimize the agro-industry sector, especially energy in biogas. In this study, the technique of the system in functional analysis is shown systematically to translate various energy requirements in the factory as criteria for performance and functional design to be integrated, optimized, and energy efficient. The case study results indicated that biogas power plants, with a capacity of 1.5 MW, can produce around 13,140 MWh per year. The annual return on investment (ROI) is around 37.13%. With this ROI value, the payback period is 31 months. The overall reduction of greenhouse gases is approximately 77,826 tons CO eq/year. The potential value of carbon trading is about USD 3,113,040 per year. This strategic model presents a novel approach by integrating biogas energy production with a customized wastewater treatment system adapted to biodigesters' effluent characteristics. It offers a sustainable, economically feasible, and scalable solution, combining resource recovery, waste minimization, and potential for carbon trading into a unified system. The novelty of this research lies in maximizing the utility of biogas plants by efficiently treating and reusing wastewater, creating a closed-loop, zero-waste process. Future research on hybrid systems integrating Biogas power plants by focusing on efficiency optimization, economic feasibility, environmental impacts, and innovative approaches like AI and blockchain could make the hybrid system a more robust, scalable, and sustainable solution. Thus, the framework based on the results of this study finds tools that can maximize and integrate energy sources, especially biogas, in the agro-industrial sector.
本研究提出的方法框架旨在整合和优化农业产业部门，特别是沼气能源。在本研究中，系统地展示了功能分析中系统的技术，将工厂中的各种能源需求转化为性能和功能设计的标准，以便进行整合、优化并提高能源效率。案例研究结果表明，一座容量为1.5兆瓦的沼气发电厂每年可产生约13140兆瓦时的电量。年投资回报率约为37.13%。基于这个投资回报率值，投资回收期为31个月。温室气体的总体减排量约为每年77826吨二氧化碳当量。碳交易的潜在价值约为每年3113040美元。这种战略模式通过将沼气能源生产与适应生物消化器出水特性的定制废水处理系统相结合，提出了一种新颖的方法。它提供了一种可持续、经济可行且可扩展的解决方案，将资源回收、废物最小化和碳交易潜力整合到一个统一的系统中。本研究的新颖之处在于通过高效处理和再利用废水，最大限度地提高沼气厂的效用，创造一个闭环、零废物的过程。未来关于整合沼气发电厂的混合系统的研究，聚焦于效率优化、经济可行性、环境影响以及人工智能和区块链等创新方法，可能会使混合系统成为一个更强大、可扩展且可持续的解决方案。因此，基于本研究结果的框架找到了可以在农业产业部门最大化和整合能源，特别是沼气的工具。
