Background and aims: Sustainable development requires economic, social and environmental stability. Considering the economic aspects of air pollution solutions, encompassing some advantages that should not be overlooked against costly and restrictive rules. Filtration system has a great importance among other air pollution control systems. In addition to the non-refundable costs and high costs of design, installation, operation & maintenance of pollution control systems make the selection process more complicated for managers as well as decision-makers. The Effective decision-making strategies are the key to addressing environmental challenges in managing and controlling air pollution. This study aimed to assess the air pollution issue based on the selection of appropriate control equipment considering economic, social and environmental criteria.
Methods: The aim of this investigation is to assess the new technologies on the basis of economical by using cost-benefit analysis. In this study profits, losses, important technical and engineering factors such as profit and cost of raw materials, design, consulting, human resources, and maintenance were considered in the design, installation and operation. This method helps the project managers in decision-making by choosing the best and most desirable options with a view to economic-executive considerations. Firstly, a primary list of modern control equipment for air pollution (gases and vapors) was prepared and evaluated by a team of experts. To find key technologies, should be assessed based on the cost-benefit criteria and the constituent elements of each option. The score of 1-3 to the elements related to the cost-benefit criteria of the selected technologies was assigned by linguistic variables. The economic value of new and common air pollution control equipment was determined by using relevant checklists based on linguistic variables. The profit-to-cost ratio and key technology ranking were derived and calculated from the cost-benefit criteria. High score will be top priorities.
Results: The results of cost-benefit analysis in terms of new technologies ranking for gases and vapors showed that the selective catalytic reduction with a cost-benefit ratio of 1.39 was the most appropriate for the gas and vapor purification technology based on economic considerations.
Conclusion: Cost-benefit analysis is a useful tool for evaluating the environmental policy decision-making process. Economic evaluation of pollution treatment systems is necessary for the reduction of cost, social and health consequences. The results of new technologies ranking, for gases and vapors have priority selective catalytic reduction (chemical reactor), plasma chemistry, cold plasma, and carbon nano-filters consequently.
