Life Cycle Assessment of the Canned Fruits Industry: Sustainability through Waste Valorization and Implementation of Innovative Techniques

Abstract

The canned fruits industry utilizes high amounts of water and energy, which results in the generation of vast quantities of wastewater and solid waste. The main scope of this study was to compare the environmental footprint of a canned fruits industry (alternative scenario) equipped with appropriate processes (pulsed electric fields, anaerobic digestion, composting, membrane bioreactors, and ultraviolet treatment) that sufficiently save energy and valorize production wastes to a typical setup that uses conventional waste methods (conventional scenario) via conducting a life cycle assessment study. Based on the results, the life cycle assessment confirmed the fact that the incorporation of the proposed methods, as described in the alternative scenario, dramatically reduced the environmental footprint of the industry, with certain environmental impact categories reaching a decrease of up to 90.00%. More specifically, according to the obtained results, a decrease of 11.81, 64.56, and 89.79% in regards to climate change, freshwater ecotoxicity, and freshwater consumption, respectively, was achieved in the alternative scenario compared to the conventional method. The study verified the environmental advantages of integrating such energy saving and waste treatment/valorization technologies across the canned fruits industry’s processing chain, contributing to environmental sustainability and safety.
