Fertileaf - Circular Economy is a project designed to provide an appropriate destination for the generation of residual tobacco dust from industrial processing. Incorrect disposal or improper incorporation of this waste into the soil can cause contamination of water bodies, groundwater and the soil. Through work in together with FUPASC - Santa Cruz do Sul Environmental Protection FoundationAfter the composting process had matured, an initiative was launched to create a composting system that applies a bacterial inoculum for controlled decomposition through temperature and humidity. Once the composting process has matured, the final product is a certified organic fertilizer called Fertileaf. Fertileaf can be incorporated and generates nutritional benefits that improve the health and productivity of the soil. After the extreme weather event in Rio Grande do Sul, which caused the biggest flood in history, many rural properties had their soils devastated and Fertileaf can help in this process of reconstituting productive soils used mainly for family farming.
