Abstract
[fr] The current global challenge of climate change has led to increased attention on sustainable development practices. In response, the circular economy has emerged as an alternative to the linear economy model, seeking to combat waste, CO2 emissions, and resource depletion. In this context, the primary objective of this work was to identify and evaluate various circular alternatives for the valorization of a by-product generated by a Slovenian brewery. The analysis explored different biomass valorization alternatives as a potential path to address the major problem of ever-increasing organic waste production through the promotion of circular economy principles.
In addition to the aforementioned analysis, the study also assessed the feasibility of implementing a Black Soldier Fly (BSF) system as an alternative to by-product management. This innovative approach involves the use of brewers' spent grains (BSG) as feed for insect farming, specifically for BSF larvae. The evaluation examined an integral set of criteria including technical, climate change mitigation potential and market assessments for this by-product management strategy within a circular economy framework.
The selected approach involved extensive research and data collection, including literature review, interviews with key stakeholders, and a review of existing documentation of the company.
This study aims to contribute to the body of knowledge on circular economy and by-product management practices within the brewing industry. By exploring different valorization options, the study advances our understanding of how breweries can effectively manage their by-products and move towards a more sustainable and resource-efficient brewing process. The results of this study provide valuable insights and practical recommendations for breweries to enhance their operations while keeping waste generation and environmental impact to a minimum.
