- In this study, issues of plastic waste to land and sea water and alternate mitigation measures were studied of plastic waste for excess generation of the plastic waste which created opportunity to meet industrial energy demand. In this study it is identified that on land dumping of plastic waste causes negative impact on soil quality. On dump site of plastic waste phosphorous and potassium was found to be higher from normal soil samples which shows the depletion of nutritional quality of dumpsite soil due to dumping of waste. There was no significant difference in level of heavy metals in sea water samples as seen in case of soil samples. This may be due to dilution factor because of rainfall, high tide low tide, and wind speed and sea bottom current. To identify the energy opportunity from plastic waste, different type of recycle plastics numbers from 1 to 7 were analysed and a range of gross calorific value obtain in range of 5500 kCal/kg to 11500 kCal/kg. This result indicates that plastic waste potential energy is fall in same range as pet coke (approx. 8500 kCal/kg) and coal (approx. 4500 kCal/kg). The gross calorific value of plastic waste indicates a possible solution of energy demand alternate in compare to the pet coke. The utilization of this plastic is tried in cement plant by the method of co-processing as an alternate fuel. The quantity of fuel, plastic and clinker produces with and without plastic waste identified throughout the process. Specific heat through co-processing shows that with fuel (plastic waste+ Pet coke) specific heat for clinkerization increases around 755 kCal/kg of clinker as compared without plastic waste as fuel (Only Pet coke) 753 kCal/kg of clinker. The resultant calculation of specific heat shows no detrimental change in the heat requirement means clinkerization is performed very well. This heat requirement not that much altered which signifies a scope as alternate fuel which can be utilized in mix of pet coke. During co-processing stack emission was also monitored and this indicates no major changes and emission is within limit. Dioxin & Furan as harmful gases emission concentration was 0.019 ngTEQ/Nm3 as compared to standard of 0.1 ngTEQ/Nm3.
