The drop is significant as MCD has set a goal of eliminating both the Okhla and Bhalswa landfill by December. The machines have to be cleaned multiple times, making it difficult to meet the output target,” a senior MCD official said. “We always advise the contracted firms to achieve their targets before the monsoon arrives because the biomining process slows considerably during this period. As of June, the MCD estimated that nearly 100 lakh TPD of legacy waste remained across the three landfill sites. Ghazipur accounted for about 69 lakh TPD, followed by Bhalswa with 18 lakh TPD and Okhla with 12 lakh TPD.
