Energy efficiency and ISO 50001:2018 implementation in seafood processing industries: A comprehensive analysis and strategic framework

Abstract

Energy is an indispensable resource in the seafood processing industry. This pioneering study explores energy efficiency using Specific energy consumption (SEC) model in Kerala's seafood processing industry, shedding light on its energy dynamics amidst growing calls for conservation and cost optimization. With an average Specific Energy Consumption (SEC) of 159.2 kWh/MT and an energy cost of 965.9 INR/MT, the industry faces notable energy challenges. The study finds a moderate correlation (0.748) between production and energy consumption, and strong correlations between production and energy cost (0.763), and energy consumption and energy cost (0.992), highlighting the direct link between energy use and costs. Regression analysis confirms that SEC significantly influences energy costs, emphasizing the need for efficient energy management. The research advocates for adopting ISO 50001:2018, integrated with the Food-Energy-Water (FEW) Nexus, as a framework for optimizing energy and resource use. A customized action plan for implementing this standard in shrimp processing facilities aims to reduce consumption, cut costs, and enhance sustainability, offering a robust foundation for future energy efficiency initiatives in the sector.
