Application of a bioenergy plant as an alternative energy source at a poultry farm

A bioenergy plant (BEP) at an agricultural enterprise generates thermal and electrical energy from biomass for production needs. The author proposes an investment project for the poultry farm Agrofirma Lipetsk OOO, involving the implementation of a BEP capable of processing biological poultry waste into energy and biofertilizer. The research aims to present a promising technology for poultry waste processing and calculate the projected technical and economic indicators of the BEP. The study considers the operating principle, feasibility, and economic expediency of using a BEP capable of annually processing 15,987 tons of chicken manure and 3,590 tons of poultry carcasses. It was established that the use of a RIELA bioenergy plant with a bioreactor volume of 4,000 m³ and a storage capacity of 550 m³ will enable the disposal of biological poultry waste and the annual generation of commercial thermal energy (887 Gcal) and electrical energy (12,116 MWh) for production needs, as well as solid biofertilizer (9,964.5 tons). According to the project, the required investment is 317.9 million roubles. The projected production effect, which includes the valuation of the generated electricity, heat, and biofertilizer, is 166.7 million roubles. Annual operating costs for the BEP will amount to 40.1 million roubles. Over the 10-year calculation period, the Net Present Value (NPV) will be approximately 550 million roubles, with a Profitability Index (PI) of 2.85 and a payback period of 4.1 years. Implementing a bioenergy plant at the poultry farm will improve the environmental situation through the zero-waste processing of production waste.
