The outcome from this research was the development of a model to assess and provide support to the management of solid waste from industries aiming at the prevention and control of industrial pollution. The proposed model was split into two parts, one aligned with a cleaner production and another with a new concept proposed by the research, a cleaner treatment of solid waste. Part I of the Model included the development of 20 indicators and the industrial solid waste destination index (ISWDI), taking into account the principles of non-generation, minimization, reuse, recycling, treatment, disposal and waste storage. Part II bears the development of 14 indicators that formed the cleaner treatment index (CTI) focused on the environmental performance assessment of waste treatment technologies, which deals with water, air, soil, energy and material issues, establishing: the minimization of solid waste generation and liquid and gaseous effluents; maximizing the efficiency of waste energy usage, reduction of fossil fuel consumption and greenhouse gas emission, minimizing the area (footprint) and the inputs required for treatment. Moreover, aiming to facilitate the standardization, analysis and supply of updated and objective information to the industrial waste managers, two numerical tools, Solid Waste Management Support Software (SAGER) and Cleaner Treatment Software (T+L), were developed. The benchmark that guided the evaluations of ISWDI was obtained from carrying out studies of environmental reports and auditable documents, as well as technical visits to automotive, cement, energy (electricity), dairy, steel and textile industries. Concerning the definition of the CT Index performance a baseline was built up for three treatment technologies: waste landfills, incineration and wasteto- energy, gathering information from visits to and data collection from approximately 200 waste treatment plants in 32 countries on 5 continents. ISWDI and CT Indexes from real data for different situations were simulated, and the final results proved satisfactory with respect to the evaluation of solid waste management and comparison of the environmental performance of treatment technologies and/or waste disposal, consisting into management tools.
