“…The process is represented by a set of mathematical equations, which describe the properties of the inlet stream, waste stream, and equipment specifications, cost functions and the degree of pollutant removal. The details of the mass and energy balance equations and the derivation of environmental function can be seen in Khan et al (2001).…”

I. ABSTRACT Cleaner and greener technologies for process and product selection and design have gained popularity in recent years. Life cycle assessment (LCA) is a systematic approach that enables selection of cleaner and greener products and processes. Recently, significant progress has been made for the use of LCA for product/process evaluation and selection, however, its use in process design and environmental decision-making has not been fully exploited. There are challenging activities which require trade-offs among conflicting attributes like cost, technical feasibility and environmental impacts. These attributes can be analysed at the early design stage by considering the full life cycle of a process (and/or a product). A cleaner and greener process referred economical, technically feasible and environmental friendly alternative. This paper proposes an integrated methodology for design by combining LCA with multi-criteria decisionmaking. This methodology is simple and applicable at the early design stage and guide decisionmaking under uncertainty. Application of the methodology is demonstrated through a case study of urea production.

“…The European Union's eco-labeling schemes (Boustead 1992), the EC directive on Packaging and Packaging Waste (HMSO 1997), and the IPPC Directive (1996) are some examples in this direction. Khan et al (2001) proposed a methodology called GreenPro for the design problem formulation using LCA, and design problem solution using multi-objective optimization and multi-criteria decision-making (MCDM). Application of the methodology was demonstrated through a case study of a vinyl chloride monomer process (Khan et al 2001).…”

I.; Veitch, B. AbstractSustainable development and environmental protection require green products, processes, and waste management strategies. The selection and design of green and clean processes and products involve handling a huge set of data related to the environment, economics and technologies. Therefore, it is essential to employ a comprehensive technique to guide decision-making under uncertainty that can incorporate these factors.The paper presents decision-making under uncertainty based on life cycle analysis and considering environmental, technological, and economical drivers in the analysis. The methodology, GreenPro-1, is applicable at any stage of a process design and can be used to evaluate the environmental burdens of a product or a process throughout its life cycle, and to identify and assess opportunities to make improvements. A weighting scheme is used to integrate various criteria and policies so that a most appropriate alternative can be selected.The GreenPro-1 methodology is applied to a case study for offshore produced water management. In the first stage, fourteen best available technologies (BAT) for treatment of produced water are evaluated individually using cradle-to-gate life cycle analysis. In the second stage, seven treatment strategies are developed from BAT and are further investigated. A treatment strategy that combines a hydrocyclone and produced water re-injection proved to be the best system among selected strategies. The combination of hydrocyclone and adsorption was found to be the next best treatment strategy. Two other noteworthy strategies were membrane and centrifuge combination, and down hole separation and injection.
