Produção de biocarvão de casca de mandioca: perspectivas de aplicações ambientais

Abstract

Biochar is a promising alternative for the transformation of organic waste, such as organic waste from the Brazilian agroindustry (such as cassava peel), into materials with the ability to improve the physical, chemical and biological quality of the soil or even in the contaminant removal. The purpose of this work is to produce biochar using agro-industrial residues (cassava peel), aiming to prepare materials that mimic the organic matter of the environment and that serve as adsorbent materials in environments contaminated by potentially toxic metals. In this work, biochar was produced from cassava bark. Seminary of Alagoas, Brazil. The production and characterization of from cassava peel showed that the increase in pyrolysis temperature enabled distinct and important characteristics for biochar, such as increased pH and reduced yield. In this way, biochar produced from cassava bark can be a viable strategy to reduce contaminants in the environment.
