Economic Benefit Analysis of Anaerobic Digestion System

Abstract

This paper aims to clarify the conditions and specific details of data collection by establishing an economic benefit analysis model, and provide corresponding economic analysis and support for the construction of anaerobic digestion plants and PTG facilities.With the implementation of China’s dual carbon policy, energy recovery and reuse and the development and use of clean energy have become hot issues. Through the corresponding literature reading, it was found that there is a new way to generate clean energy biogas abroad, and the biogas produced is used for power generation, that is, PTG facilities. At present, PTG facilities have not been studied in the literature. In order to consider the feasibility of establishing facilities, it is necessary to analyze the economic benefits, and the profits generated by the facilities can form a virtuous circle, so as to continue to invest in the construction, maintenance and construction of other supporting facilities.Based on the collected data, the calculation is carried out, considering the cost of labor, raw materials, and maintenance, and the final calculated profit is CNY4.33 109. Although it is necessary to increase the cost of maintenance and replacement of equipment inside the facility, the costs covered in this article account for only a small part of the total revenue, and the proportion of government subsidies in the income is much smaller than the proportion of power generation revenue, so the facility has great development prospects.
