The value that is added to the value of intermediate goods in the production process is called Economic Value-Added (EVA). This concept is related to the production process and not to a specific commodity. Due to the wide variety of goods required, most of the needs of society are provided by the Chemical Industries Group. Chemical industries are part of the industry, which convert the chemicals needed by other industries to produce more than 70,000 products through conversion. Raw materials supply the required materials. Sales of the chemical industry can be divided into several broad categories, including basic chemicals (about 35 to 37% of production), life sciences (30%), particular chemicals (20 to 25%), and consumer products (About 10%). The tabulated data were selected from the screening step of project identification in the Environmental Impact Assessment (EIA) plan of industrial projects belong to both the Iranian environment protection agency and Iranian industries organization. To classify the five Iranian chemical industries was employed EVA using empirical equations. Results were allocated for depreciation outlay, and unforeseen costs via considering the percentage of outlays of required land, landscaping, buildings, pavement, and asphalt; Investment in facilities; Investment in equipment and the installation costs; and investment in transportation facilities. Finally, the industries were assorted based on EVA from the highest percentage manifested to the lowest one as well as simple reports of costs in tables. Findings declare that the screening step of industrial projects in project identification is an indispensable stage in conducting an Environmental Impact Assessment (EIA) plan.

Graphical Abstract

Classification of five Iranian chemical industries based on economic value-added


  • The EVA is used to rank and classify the industrial groups by the statistical center of Iran.
  • The project cycle involves site selection, screening, initial assessment, and scoping of significant issues.
  • The main variables interfering in the estimation of EVA are the price of products, outlays of energy, costs of feedstock, unforeseen costs of fixed capital, and depreciation costs (maintenance, operational and non-operational fixed annual capital).
