Produção de briquetes com lodo de ETA e serragem de Pinus sp

Abstract

Landfills that receive sludge from Water Treatment Plants (ETA) play a crucial role in solid waste management and protecting the environment. The sludge generated during the water treatment process in WTPs generally contains a variety of organic and inorganic substances, as well as microorganisms.Proper disposal of sludge is essential to avoid negative environmental impacts, such as soil and groundwater contamination. Landfills are a common option for the final disposal of ETA sludge. This study focuses on the use of sewage sludge as a raw material in the manufacture of briquettes, generating a source of fuel from the mixture with pine sawdust. and consequently, avoiding their disposal in landfills. The research evaluates the technical feasibility and potential of this biomass as a fuel source. Sludge characterization, briquette composition analysis and implementation of experimental methods were carried out. The results indicate that the production of briquettes from sewage sludge is a promising alternative, contributing to waste reduction and offering a sustainable source of energy.
