The University of Costa Rica (UCR) designed a system that reuses coffee waste and transforms it into energy. The model seeks to reduce greenhouse gas emissions and increase energy efficiency. Coffee is one of the most consumed beverages in the world, and Latin America stands out as one of the main producers of this bean.
Nonetheless, producing 2.3 kilograms of ground coffee requires an investment of 100 kilograms of fruit. As the coffee undergoes processing and is converted into waste, the initial quantity of coffee within the fruit is doubled.
Coffee growers in Latin America require new ways of managing coffee residues to prevent contamination and the production of greenhouse gas emissions.
Juan Pablo Rojas Sossa, from the School of Biosystems Engineering of the University of Costa Rica, created a project that allows reusing coffee waste and transforming it into energy and nutrients.
