Construction and Demolition Waste Recycling

Criteria for Storage and Processing under C&D Waste Recycling

• Operator of the facility must submit an annual report to the State Pollution Control Board.
• Operator must apply in Form 1 for authorization from the State Pollution Control Board.
• Site must be away from habitation clusters, forest areas, water bodies, monuments, national parks, etc.
• A buffer zone of no development shall be maintained around the waste disposal and processing facility.
• Construction waste management facilities must abide by the SPCB's pollution control standards.
• The C&D facility must be duly fenced or hedged with proper gates.
• Work zone air quality and ambient air quality must be monitored in the vicinity.
• A vegetative boundary shall be made around the C&D recycling plant to strengthen the buffer zone.

• The wastes generated from construction and demolition activities must be initially collected and transported to a recycling facility under construction and demolition waste recycling in India.
• The hazardous waste materials must be sorted and separated into different categories.
• Larger pieces of concrete, masonry, and asphalt must be crushed and ground into smaller pieces for easier processing.
• Metals must be separated from other materials using a magnet or eddy current separator.
• Wood waste must be chopped or shredded into smaller pieces for use as fuel, mulch, or in the production of engineered wood products.
• The separated materials must be processed further to produce new products or serve as feedstock for the manufacturing of new products.

Strategies for Construction and Demolition Waste Recycling

The strategies used for construction and demolition waste recycling are as discussed below:

• Reducing the use of materials and minimizing the waste generated at its source.
• Reusing materials and fixtures like doors and windows in other construction projects.
• Recycling materials such as concrete, bricks, and metals for reuse in new construction projects.
• Recovering energy from certain waste materials through processes like incineration or anaerobic digestion.
• Disposing of C&D waste that cannot be reused, recycled, or recovered in an environmentally safe landfill.
• Rebuying used C&D materials and recycled content products for reuse in new construction projects.
