In Brazil, G1 reports research developed by the Federal University of Lavras (UFLA) has shown that coffee residues, such as the bark, can be repurposed and transformed into a clean energy source. The study seeks sustainable alternatives to reduce waste and generate new use opportunities for agricultural by-products.
According to the researcher, the work resulted in the production of pellets, small cylinders of solid biofuel obtained through a biomass densification process, known as pelletization.
During the process, the coffee peel, normally discarded after processing, is inserted into a machine called pelletizer. From there, the material is compacted and cut into pellets about six millimeters in diameter, which facilitates transportation, storage and use as fuel.
The research also already has practical application: a company from Varginha uses the pellets produced from the coffee shell in an industrial process of reducing manganese ore. The model, according to Protasius, demonstrates that it is possible to add value to the waste and promote regional development.
