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.

Prioritizing groundwater remediation policies: A fuzzy compatibility analysis decision aid

“…In this way, the impacts are assessed in the form of linguistic attributes expressed via fuzzy sets (Zadeh, 1975a-c). The impact assessment using linguistic terms and fuzzy sets has been recently considered as a significant field of study with numerous real world applications (Silvert, 2000;Marusich and Wilkinson, 2001;Martı´n Ramos et al, 2003;Sadiq et al, 2005;Shepard, 2005). In our study, impacts are addressed by the linguistic terms VI, I, D and VD (abbreviated form of 'Very Increasing', 'Increasing', 'Decreasing' and 'Very Decreasing'), which are expressed by the following fuzzy sets:…”

Development of environmental consequence index (ECI) using fuzzy composite programming

“…Sadiq et al [29] developed GreenPro-I, a decision-making methodology for design problem formulation using LCA, and design problem solution using multi-objective optimization and multicriteria decision-making (MCDM). But its application restricted to early stage design.…”
