Integration Techniques for Environmental Impact Assessment of Industrial Pollutants

The integrated management of medium (both water and air) based pollutants is vital at current as the management and legalization of individual pollutant is very difficult. Various environmental aspects associated with the different medium during the production processes are major challenges being faced in the environmental management of industrial facilities. It is of vital concern today to find the scientific way of integration of medium-based pollutants. Based on an amount and kind of medium-based pollutants, Integrated Environmental Performance Score (IEPS) is calculated applying Tool for the Reduction and Assessment of Chemical and other Environmental Impacts (TRACI). The potential impacts of individual pollutants have been modelled for water based pollutants viz., Chemical Oxygen Demand (COD), Total Phosphorous (TP), and Total Nitrogen (TN) and air pollutants viz., Oxides of Nitrogen (NOx), Oxides of Sulphur (SOx) and Particles Matter (PM10). A kilogram of individual pollutants is taken in modelling to compute the individual impact categories of unit pollutants. The EPS penalty of TN is obtained as highest score of 189.70 i.e. 90.82% shares among six pollutants. The total penalty score for TP, PM10, TN, NOx and SOx, is derived as 13.53 (6.48%), 2.59 (1.24%), 1.30 (0.62%), 1.30 (0.62%) and 0.44 (0.21%), respectively. Hence, it is necessary to integrate effects of pollutants as per the scientific and justified impact caused by individual pollutants derived from the industrial facilities. Therefore, this study recommends for the compliance of EPS penalty of the pollutants based on a result of TRACI. This helps to enforce a scientific and justified polluters’ pay principle.
