Abstract

AbstractThis study involves an extensive examination of the brewing industry, specifically focusing on Company A in South Vietnam alongside five other Vietnamese beer companies (B, C, D, E, and F). By employing a multifaceted approach that integrates Life Cycle Assessment (LCA), evaluations of emission loads, and the establishment of criteria for a circular economy model, the study aims to investigate environmental impact, waste generation, energy consumption and potential circular solutions within these breweries. The findings from the survey indicate similarities in the fundamental production processes among the surveyed factories. However, differences were noted in technological advancement and the utilization of raw materials. Challenges in acquiring data, driven by industry competitiveness, highlighted discrepancies in technology investments and the implementation of circular solutions across the breweries. Assessment of emission loads, wastewater and exhaust gas data demonstrated Company A's compliance with environmental standards. Nonetheless, comparative analysis revealed that the water and energy consumption of Company A were 1.5–2.5 times greater, with carbon emissions of 2000–6000 kgCO2eq/m3 product, compared to other breweries. The comprehensive LCA uncovered higher water and energy footprints in Company A, emphasizing potential areas for significant improvements in water usage efficiency and energy conservation. Through the creation of a preliminary set of criteria, subsequent screening, and expert consultation utilizing the Analytic Hierarchy Process (AHP), a set of 21 criteria was established. This system supports the assessment of current brewery statuses and identifies potential pathways for improvement towards a circular economy model. Recommendations include the adoption of industry‐agriculture models, waste recycling, energy efficiency initiatives and the integration of renewable energy for sustainable development in beer production.
