Aproveitamento da biomassa de coco verde para produção de biocombustíveis sustentáveis

Abstract

Solid waste is a global problem, many countries such as India, Germany, Finland, among others, already use sustainable technologies to reduce the impacts caused by MSW on the environment. In Brazil, the alternative used to minimize this impact is landfills. However, the volumes of green coconut residue have attracted attention across the country. According to IBGE, in 2017 approximately 1.8 million fruits were produced, with the Northeast region responsible for 75% of the total produced. In view of this scenario, this work carried out a survey of data on the generation of green coconut waste in the city of João Pessoa using data from 2007 and 2018 prepared by EMLUR- Special Municipal Cleaning Agency and identified that all this waste is destined to the landfill, compromising its useful life and impacting the environment through vectors and gas generation at the landfill. The compiled data showed that in 2007 around 1 million units of coconut were generated in the city of João Pessoa and the survey carried out in 2018 showed new points of sale of coconut. The research also carried out the characterization of green coconut biomass by identifying the thermal behavior of the mesocarp and endocarp. The Higher Calorific Power of green coconut biomass showed values similar to other forest crops. The rapid pyrolysis performed at temperatures of 500 ° C, 550 ° C and 600 ° C of the coconut residue presented oxygenated compounds with potential raw material for biofuels.
