Guidelines based on life cycle assessment for solvent selection during the process design and evaluation of treatment alternatives

摘要: The aim of this paper is to develop guidelines in order assist decision making with respect treatment options waste solvents, and more importantly for the choice solvent design process a priori, from an environmental point view based on composition mixture. Life cycle assessment (LCA) was used evaluate two alternatives: continuous distillation incineration. software Ecosolvent® v.1.0.1 perform LCA, considering scenarios (the best worst scenarios) five indicators: Eco-indicator 99, UBP-97, global warming potential, cumulative energy demand CO2-balance. From results, it can be concluded that impact originating production solvents main issue consider selection or incineration as method during design. In general, those low their stage were found candidates Moreover, compounds yield great burden step should always recovered minimize total impact. A series charts presented select most environmentally favorable alternative mixtures which use effects are produced. Regarding information given by different indicators, observed all studied indicators lead same conclusions evaluated some exceptions UBP-97.
