The plant installed converts waste collected from the garbage disposal units into carbon powder, diesel and gas using Polycrack Technology. The diesel oil is to be sold by the Railways to other stake holders for commercial purposes. The gas and carbon powder are to be used in brick manufacturing. The best thing of the plant is that it does not leave any waste at the end.

The plant has the capacity to process 500 kg of waste per day and will earn Rs 17.5 lakh per annum.
