Sistema logístico de manejo de residuos de café en empresas guayaquileñas 2023-2024.

Abstract

This essay analyzes the logistics system used for managing waste generated by the coffee processing industry in Guayaquil during the period 2023–2024, with the aim of identifying opportunities for improvement aligned with the principles of the circular economy and environmental, energy, and financial sustainability. The central idea of this analysis focused on current practices for the use and management of waste materials such as husks, honey water, pulp and other byproducts. Among the most representative companies used as case studies or examples in te sector are Nestlé Ecuador, Solubles Instantáneos C.A. (SICA), ELCAFÉ C.A., and Café Minerva. Some companies in the coffee sector have implemented "zero waste to landfill" campaigns and it is important to mention that the hold certifications such as ISO 14001 and ISO 50001. The study revealed weaknesses in areas such as the valorization of generated byproducts, transparency and traceability. Many waste products are viewed as operational problems rather than production opportunities. The study concluded that coffee waste can be reused in various ways, including as an input for composting processes; as raw material for bioplastics; and for generating thermal energy as biomass; and trough anaerobic digestion for biogas production. Despite all these possibilities, there are process deficiencies, a lack of logistical equipment, limited coordination between organizations, and a high moisture content in the waste that make sustainable production of this waste unlikely.
