Potencial de aplicação do resíduo de cinza de casca de arroz

Abstract

The use of agricultural waste has become a necessity due to its high environmental cost. As an example of this, we have rice husk ash (CCA), produced by the indiscriminate burning of rice husk, as well as the need to look for alternatives to reuse the waste sustainably, either by applying it to nanomaterials or by extracting SiO2 present in rice husk ash. This study addresses the use of characterization techniques for rice husk ash residue, showing the quality of SiO2 present in the residue.
