NEW DELHI: North Delhi Municipal Corporation has set up 316 composting sites to prevent open burning of leaves and reduce the load on the already overflowing Bhalswa landfill site.

The composting sites will work along with four newly procured mobile shredder and chipper units. The project, which will help in scientific disposal of green waste, is being touted as a major step towards the corporation's target of zero green waste.

"North corporation has the most number of parks in the capital at 5,944. In addititon, a lot of waste is generated because of pruning of roadside trees. In the initial phase, we will be able to convert all the green waste generated by us into eco-friendly manure instead of dumping it at the landfill site. Burning of open leaves will also reduce significantly," said a north corporation official.

A wood chipper machine chops large chunks of biodegradable waste into small chips. This not only enhances the pace of composting but also reduces the volume. "It reduces the volume by 10 times. As the same truck can transport ten times the waste, a large number of trucks will get free and can be used to for other solid waste. The composting time also reduces to 10-15 days," the official explained.

North corporation mayor Preety Aggarwal said, "The chipper machines will convert waste into manure and the corporation will have to spend less on buying manure from external agencies".

The horticulture department of the civic agency took a 10-day training to shift to the new waste management system. Apart from developing the composting units across all six zones, the corporation has also deployed two mobile chippers in Rohini zone, and one each in Karol Bagh and Civil Lines under the first phase. "The process of procuring more units has been started," added the mayor.

At present, the north corporation areas generate about 3,800MT of solid waste every day and according to the civic body, almost a fifth of it can be converted into manure. "If proper segregation is ensured as per the solid waste rules, green waste management will significantly reduce the load on landfills," said north corporation spokesperson Yogender Singh Maan.

Despite NGT's strict guidelines in place, burning of leaves continues to remain a major problem. "In over 360 such cases this year, we have recovered about Rs 10 lakh in challan money. We plan to install more shredders in our zones," said another senior official.
