Prevenção da poluição: uma gestão pró ativa e sustentável na redução de resíduos sólidos: estudo de caso de uma indústria química brasileira

Abstract

Hazardous waste produced by industry are particularly worrying, because when improperly managed, become a serious threat to the environment. The generators are required by the competent bodies to take care of management, transportation, treatment and disposal of its waste, and that responsibility is forever. The aim of this study was to evaluate the alternatives for allocation of hazardous solid waste generated in Braskem in production of PVC Soda and Chlorine in Alagoas from the elimination of values in Class I Solid Waste Unit of Braskem PVC Alagoas. A major challenge is balancing the cost cycle, because there will be a cost increase in the production of a particular product, coupled with investment needs. The best way is to act strongly on reducing solid waste generation and seek alternatives for reuse of these wastes. The economic analysis of the feasibility of deploying new technologies will result in an increase in production cost of products produced in Braskem PVC/AL and Braskem CS/AL, but it will be extremely critical to reducing the environmental burden of waste that are arranged in intervals for hazardous waste. Measures to reduce waste at source should be evaluated and adopted in accordance with its technical and economic feasibility, with a sustainable vision and those who are neither technically nor economically feasible in the current context, should be postponed to a later realization.
