Abstract

Industrial activity for leather production generates large amount of potentially polluting waste, rich in organic and inorganic toxic substances, especially chromium. This scenario is present in several regions of Brazil, especially the mesoregion of Bauru - São Paulo State, Brazil, polo reference in this industry segment. Waste generated in leather processing and production comprises mainly the solid fraction (tanned shavings and chips) and also the sludge treatment plants. An alternative to the environmental problem involving these residues would transform them into organic compounds noble, in which the vermicompost is presented as a viable alternative. Vermicomposting is a type of composting in which emphasizes the action of detritivore earthworms and microorganisms in your digestive tract. The results reported in the literature are promising, but restricted the prism of agriculture and other agricultural sciences. In this work, the waste will be fresh and chemically analyzed via spectroscopic methods. Moreover, the whole process of vermicomposting will be monitored from start to obtain the vermicompost in biweekly analysis. At the end of this step, the vermicompost will be incorporated into the soil and then applied to the cultivation of green bell pepper (Capsicum annuum L.) plant to develop demand certain amount of chromium in the soil. Thus, this study aims to determine the potential use of industrial waste produced during industrial processing of leather, featuring vermicomposting as an alternative for this environmental liabilities, performing a chemical and spectroscopic study of the dynamics of this process, indicating the path and phenomena occurring along the humification of organic matter.
