Estudio de alternativas de reutilización del bagazo producido en la industria cervecera

Abstract

A nivel mundial la industria de la cerveza se considera una de las agroindustrias más importantes mundialmente. Según la Organización de las Naciones Unidas para la Alimentación y la Agricultura, se producen 114.000.000 kilogramos de cervezas al año. En consecuencia, se produce una cantidad incontrolada de residuos sólidos, con la máxima preocupación en el bagazo de malta ya que representa un 85% de los residuos totales que se producen en la industria cervecera. Existen muchas alternativas para la reutilización de este subproducto generado, destacando su incorporación en otros procesos industriales que mejoren la economía circular. El objetivo de este proyecto es el estudio de distintas alternativas posibles para su reutilización, concretamente en la producción de biogás y la obtención de compuestos antioxidantes a partir de este. Esto contribuye al desarrollo de sistemas sostenibles en la producción de cervezas. En primer lugar, se explica brevemente el proceso de producción de cerveza artesana para poder así realizar un balance de materia con el objetivo de conseguir una cantidad de bagazo, el cual va a ser tratado en las distintas alternativas mencionadas anteriormente. A continuación, se desarrollan ambas alternativas, describiendo detalladamente sus respectivos procesos. Y para finalizar, se ha hecho un estudio de viabilidad económica.

Worldwide, the beer industry is considered one of the most important agro-industries in the world. According to the Food and Agriculture Organization of the United Nations, 114,000,000 kilograms of beers are produced annually. Consequently, an uncontrolled amount of solid waste is produced, with the utmost concern in malt bagasse as it accounts for 85% of the total waste produced in the brewing industry. There are many alternatives for the reuse of this generated by-product, highlighting its incorporation into other industrial processes that improve the circular economy. The objective of this project is the study of different possible alternatives for its reuse, specifically in the production of biogas and the obtaining of antioxidant compounds from it. This contributes to the development of sustainable systems in beer production. First, the production process of craft beer is briefly explained in order to make a balance of matter with the aim of achieving a quantity of bagasse, which will be treated in the different alternatives mentioned above. Both alternatives are then developed, describing in detail their respective processes. And finally, an economic feasibility study has been carried out.
