DPCC report on C&D waste, 25/09/2020
Action taken report on behalf of Delhi Pollution Control Committee in compliance to the National Green Tribunal order of May 20, 2020.
The matter related to management of construction and demolition (C&D) waste. The NGT had directed that steps should be taken to ensure increase of off take and lifting of C&D recycling material. Capacity for processing of waste needed to be adequately enhanced within a specified timeline. Also, it was not desirable to allow dumping of C&D waste at Bhalswa landfill site, which had already crossed its capacity.
The report by DPCC stated that approximately 3900 tonnes per day (TPD) of C&D waste was generated in Delhi, which required dedicated handling mechanism and disposal. Accordingly, separate collection and transport infrastructure of C&D waste had been set up under which the C&D waste was collected at ear marked sites identified by the three municipal corporations (North Delhi Municipal Corporation, East Delhi Municipal Corporation, South Delhi Municipal Corporation), New Delhi Municipal Council and Delhi Cantonment Board.
The waste was transported to the construction and demolition waste processing and recycling facilities in Delhi. After commissioning of one new Construction and Demolition Waste Processing Facility at Bakkarwala and expansion of the capacity of the C&D waste processing facility at Shastri Park from 500 TPD to 1000 TPD, now there are 4 operational Construction and Demolition Waste Processing plants in Delhi with a total capacity of 4150 TPD.
In these processing facilities, paver blocks, kerb stones, bricks, sand and soil of Bureau of Indian standards were being produced out of the C&D waste. These are used in the infrastructure projects, thus fresh requirement of natural resources had been minimized.
