In this paper, we are analyzing industrial plastic waste and chemical processes on it which results into pollution. The dynamical model starts with by investing the total budget into health policy for the civilization by decreasing the burning of plastic and increasing to install the recycling machine for dumped industrial plastic. Both are strides to economic progress of the country. With appropriate conditions, local stability is qualitatively analyzed in the model containing the system of non- linear differential equations. Graph theory results help to know the global stability behavior of the model. Techniques to reduce plastic pollution are outlined by optimizing both the policies which is simulated numerically with given validated data.

Estimation said that out of these only one-quarter is recycled. Plastic is prepared from toxic materials like vinyl hydrochloride, benzene etc. These chemicals cause the precarious health issues and also contaminate our air, soil and water. The huge bulk of industrial plastic is non-biodegradable and if it is degradable then it only starts degrading in about 700 years which means that all the plastic that has ever been produced has not degraded yet. Therefore, these dumped industrial plastics are either burned or recycled. One should recycle all the things of plastic rather than new production and burning. Keep it away from environmental sources such as landfill and ocean. Because when the industrial waste plastic composed in dumping sites, it keeps rotting, spreading odour which cause the air pollution.
