Corpn plants turn construction waste into usable sand, gravel, paver blocks
April 17, 2025
|The New Indian Express Chennai
WITH the GCC's new Construction & Demolition Waste Management Guidelines set to be effective from April 21, the civic body is transforming C&D waste into construction materials — from fine sand and gravel to paver blocks through the Greater Chennai Corporation's (GCC) C&D waste processing plants at Perungudi and Kodungaiyur dumping grounds.
Waste materials are being recycled into 6mm to 20mm aggregates, M sand (4.75mm to 2.5mm), and P sand (2.52mm to 0.75mm). Even sludge from the treatment process is being reused as filling in construction or in the glass industry.
Recycled sand produced from concrete boulders using vertical shaft impactor technology is 30% cheaper than regular sand, said K Sundar, technical adviser of We Start Communications India Pvt Ltd - the firm operating the plants on the Public Private Partnership with GCC. It has also supplied the recycled materials to major firms like L&T and Corporation contractors.
