The Portland cement production process is a highly polluting sector, approximately 90% of greenhouse gas emissions come from clinker production. New techniques for the manufacture of cement are being developed, such as the incorporation of waste from other industries. The objective of the present study was to investigate the environmental feasibility of using alkaline solid residues, called dregs and grits, from kraft pulp mill, for the production of Eco-cement. The methodology includes the following phases: Characterization of Eco-cement and Life Cycle Analysis (LCA) of this industrial process. The results showed that the addition of residues is responsible for the reduction of CO2 emissions and, consequently, minimizing environmental impacts in its production process. The environmental feasibility of using alkaline solid residues from kraft pulp mill as raw material in the production of Eco-cement showed to be an interesting approach to manage environmental, technical and economic aspects of the industry.
