Reutilização de fundos de tanques como estratégia de sustentabilidade e otimização de custos para microcervejarias

Abstract

This study investigates the reuse of tank bottoms as a strategy for sustainability and cost optimization in microbreweries, proposing the production of Hop Lager beer from the bottoms of Pilsen beer tanks. The research aimed to assess the technical and economic viability of this approach through clarification and dry hopping processes, complemented by sensory and physicochemical analyses, and a detailed economic study. The results showed that the new methodology made it possible to obtain a final product with a uniform sensory profile and high quality, maintaining the standards demanded by the market, while at the same time reducing the need to withdraw large volumes of Pilsen draft beer from stock, from 4.0% to 1.0%, and recovering around 13,656 liters of beer annually from the tank bottoms. It can be concluded that the application of this innovative technique not only optimized the production process, but also contributed to minimizing losses and reducing operating costs, representing an economically advantageous and environmentally sustainable solution for the sector.
