Abstract
Abstract Purpose The purpose of this work is to evaluate the environmental impacts of mezcal production from Agave cupreata in Michoacán, México. The central question is the influence of management options for vinasse, bagasse, and biomass energy. Methods The study was conducted using life cycle assessment (LCA) based on the conceptual framework of ISO 14040, guidelines of ISO 14044, and material and energy flow analysis, in a cradle-to-gate approach. The functional unit considered is a packaged mezcal of 0.75 ls produced in compliance with the official Mexican standard for this type of alcoholic beverage. Site measurements were conducted at two agave processing facilities, and descriptive surveys were carried out in collaboration with local producers. Related ecoefficiency indicators were evaluated and shown in a transparent and reproducible way. Environmental impact categories such as global warming potential (GWP), fine particulate matter formation (PMFP), freshwater eutrophication (FEP), and cumulative energy demand (CED) were calculated. Results The results indicate that bioenergy is 87% of the cumulative energy for production. The main source of impacts from the PMFP category was the distillation process (50%). The vinasse contribution is around 60.4% for the FEP category. Bagasse’s contribution to the GWP category is around 22.7%. Even though carbon dioxide produced from biomass is considered biogenic, the overall impact is still significant due to the presence of other compounds such as methane. We also evaluate barriers to the implementation of alternative waste management technologies for bagasse and vinasse. Conclusions From this study, it is concluded that biomass energy plays a crucial role in the sustainable manufacturing of mezcal.
期刊介绍:
The International Journal of Life Cycle Assessment (Int J Life Cycle Assess) is the first journal devoted entirely to Life Cycle Assessment and closely related methods. LCA has become a recognized instrument to assess the ecological burdens and impacts throughout the consecutive and interlinked stages of a product system, from raw material acquisition or generation from natural resources, through production and use to final disposal. The Int J Life Cycle Assess is a forum for scientists developing LCA and LCM (Life Cycle Management); LCA and LCM practitioners; managers concerned with environmental aspects of products; governmental environmental agencies responsible for product quality; scientific and industrial societies involved in LCA development, and ecological institutions and bodies.
