Análise de viabilidade econômica e ambiental do carvão vegetal, briquete e pellet como fonte de energia

Abstract

The need for alternatives to energy sources is increasingly necessary today, given that the influence of certain sources can be detrimental to the environment. The main objective of the work is to investigate charcoal, briquettes, and pellets for energy generation, comparing them with other commonly known sources, such as solar, wind, and hydroelectric power. It is proposed to study a classification of these sources, considering economic and environmental aspects using the SAW (Simple Additive Weighting) classification method along with a weight classification for each criterion using the Entropy Weight method. From this perspective, the use of charcoal, briquettes, and pellets may present a good classification in relation to other energy sources, considering aspects such as KWh, initial project investment, payback time, noise pollution, and CO2 emissions. Wind power obtained the highest score, followed by solar power, while charcoal, briquettes, and pellets appear in third, fourth, and fifth place, hydroelectric power with the lowest score.
