The cleaner production (CP) methodology was implemented in an industry in the furniture sector as a management tool for achieving eco-efficiency and obtaining environmental and economic benefits. Based on the application of CP principles to a Brazilian furniture factory, audits of raw material and water consumption were proposed for the manufacturing divisions of this company and for the generation of solid waste and effluents. Tools were implemented for assessing material flow, aimed at the development and analysis of the mass balances of the processes involved. These tools supported the identification, evaluation and implementation of actions addressing five CP opportunities that were preventative in nature, resulting in reduced generation of solid wastes and liquid effluents and a decrease in the inflow of raw material inputs and water. A saving of 66% in water and 3% in raw materials consumption was obtained, and there had been a reduction of 23% in the solid waste and 93% in the effluents generation. The production cost per unit was on average US$ 0.14 lower than before. The economy of wood will prevent the cutting of around 3900 adult pine trees and the emission of 13,100 kg of carbon dioxide equivalent in the waste and raw materials transport, which is an additional environmental gain.
