A Comprehensive Study on Evaluating the Environmental Effects and Energy Use Efficiency of Producing Animal Feed from Sugarcane Bagasse

Abstract

Sugarcane bagasse, a by-product of sugar production, has potential as a feed ingredient for animals. This study examines the environmental impact and energy use efficiency of using sugarcane bagasse for animal feed. The research indicates that the total energy consumption for producing fodder is 30,329.94 MJ ton⁻¹, with input energy exceeding output energy. Sugarcane bagasse accounts for over 50% of energy consumption, along with significant contributions from electricity and natural gas. Energy efficiency and intensity are calculated at 0.03 kg MJ⁻¹ and 30.32 MJ kg⁻¹, respectively, suggesting a high energy requirement per kg of feed. The net energy is calculated at -5329.94 MJ ton⁻¹, highlighting inefficiencies in energy use. The study shows a measurable impact on human health (0.30 DALY) but a relatively minor impact on ecosystem quality (0.0005 species.yr). The high energy consumption of 93,602.34 MJ ton⁻¹ indicates a heavy reliance on non-renewable fuel sources, specifically fossil fuels. These findings underscore the importance of improving energy efficiency and resource utilization in feed production processes.
