Potencial da casca de coco para produção de briquete

Abstract

Given the environmental and energy scenario in which the world currently finds itself, meetings are held to promote international climate policies that aim to establish greater participation of renewable sources in their matrices to promote the energy transition. Considered the largest renewable source of energy in the world, biomass has been gaining notoriety for the diversification of energy and electrical matrices. With a favorable climate and topography, Brazil is considered one of the largest agricultural and forestry producers in the world, with great potential for the production of briquettes and pellets from the use of agroforestry residue generated. Briquettes, a product resulting from milling and compaction, made from lignocellulosic waste are viable for use and a great ally in the total energy use of waste from agricultural and forestry management. The present study aims to analyze the energy potential for producing briquettes from green coconut shells using variations in mixing percentage, use of corn starch and water binders, and compaction at room temperature and after application of 70oC to the sample. The factors analyzed were: humidity, average density, and compaction. It was observed that the samples made with the addition of corn starch binder without and with the application of temperature before compaction did not obtain positive results, regardless of the percentage of the mixture used. The samples that obtained the best results in terms of density and compaction were prepared with the binder water, which allows for simpler and cheaper production, validating the objective of the study.
