The Greater Hyderabad Municipal Corporation (GHMC) is following the Construction and Demolition waste model for proper disposal of waste, says K V Karthik, Deputy Environment Engineer, Solid Waste Management, GHMC.

What is Construction and Demolition (C&D) waste?

The C&D waste includes concrete, bricks, tiles, stone, soil, rubble, plaster, drywall or gypsum board, wood, plumbing fixtures, non-hazardous insulating material, plastics, wall paper, glass, metals (such as steel, aluminium), asphalt, etc. It is estimated that 25–30 million tonnes of C&D waste is generated in the country annually.

Bulk Waste Generators (BWG)

The Bulk Waste generators are those who generate more than 20 tonnes in one day or 300 tonnes per project in a month.

Responsibilities of Bulk Waste Generators

In a month, BWGs shall segregate the waste into four streams such as concrete, soil, steel, wood and plastics, bricks and mortar and shall submit waste management plan and get appropriate approvals from the local authority before starting construction.

Benefits of Processing Construction and Demolition Waste:

  • Saves natural resources
  • Prevents public nuisance and traffic congestion
  • Saves valuable space at landfill sites
  • Reduces cost of bulk transportation if recycled close to source of generation.
  • C&D and other inert waste may be utilised for making bricks, pavement blocks, construction materials such as aggregates etc
  • Establishment of C&D recycling plants in GHMC
  • It is estimated that GHMC produces C&D waste of 1 million tonnes annually.
  • Four C&D plants of 500 TPD are planned. Presently the two plants are in the finalisation stage and is about to start the process.
  • Proposal for one more plant is under process
  • Four clusters were identified for the C&D waste plant. i.e. Fathullaguda (15 acre), Mallapur (5 acre), Kothwalguda(8 acre) and Jeedimetla(10 acre).

Every waste generator shall pay relevant charges for C&T and Planning & Design (P&D) as notified by the concerned authorities; BWGs shall have to pay for the P&D of C&D waste generated by them, apart from the payment for storage, C&T.
