Preparation and characterization of biodiesel industry waste partially carbonized material in order to produce an organic soil conditioner.
This work seeks to determine the best methods of production of partly carbonized waste of biodiesel industry - castor (Ricinus communis) meal - aimed at obtaining material comparable to organic matter of soils Terras Pretas de Índios to be used as a soil conditioner. The subject Terras Pretas de Índios has aroused interest in the international scientific community that in recent years several articles and letters of Nature and Science were devoted to the subject (e.g. 1, 2, 3) and The American Association for the Advancement of Science (AAAS) organized a symposium in their annual meeting in 2006 with the title: Amazonian Dark Earths: New Discoveries. This work corresponds to chemical studies in the sense of scientific knowledge and technological development and innovation in the use of organic by-products, especially from the biofuels industries, seeking the excellent performance of the so-called Terras Pretas de Índios of the Amazon (4). In these work the carbonized materials were obtained by controlled heating of different mixture of biodiesel industry tort with glycerol, starch as industrial Brazilian by-product, and potassium sulfate (K2SO4) as a macronutrient addictive. The obtained products were analyzed by EPR, NMR, and DRUV-Vis spectroscopy.
