In order to scientifically channel the huge Construction and Demolition Waste generated by the city of Surat, Surat Green Precast Private Limited (SGPPL), in 2019, set up a state-of-the-art C&D Waste Recycling plant from CDE Asia.

ReUrban Compact from CDE is a one-of-a-kind C&D Waste Recycling Plant with a capacity to process 300 TPD - enough to handle the entire city’s C&D waste. It is equipped with a specialized segregation system, debris handling section, crusher, a multiple section screening unit, etc, that ensure that the C&D waste is processed in an efficient manner to produce an impressive line of repurposed products with minimum environmental footprint and water usage.

Kanoj Lakhani, Managing Director, SGPPL, says “Our aim is to build the best products from waste, cause no unnecessary harm to the environment, and apply business acumen to inspire and implement solutions for the environmental crisis due to the waste produced in construction projects. We have achieved all this with the commissioning of the CDE Plant. From a total of 50 points last year, ranking points for C&D waste management for Swachh Survekshan 2021 have been doubled to 100 points – 50 points for recycling and 50 points for reusing the products. All the products have been tested by the National Institute of Technology in Surat (SVNIT) and we have started producing paver blocks from recycled sand and aggregate. We have achieved a compressive strength of 50 n/mm2 while using 100% recycled material.”

He informs that Banchhanidhi Pani (I.A.S.), Municipal Commissioner, S.M.C, has given the approval to buy back 10% of products required by SMC. The volume of buyback will be reviewed periodically, and the percentage increased accordingly.

The plant strengthens SGPPL’s vision of a greener Surat by efficient recycling of waste consisting of cement concrete, cement mortar, bricks, rubble, stone, sand and soil to produce high grade washed and dewatered sand and aggregates by removal of oversize and ultra-fines. The state-of-the-art technology recycles and restricts the usage of water to a mere 6-8 m2 and limits power usage to 120 KWH, making it extremely eco-friendly.

The C&D Waste Recycling plant promises to:
  • Recover aggregates, plaster and sand from Construction & Demolition Waste.
  • Provide high yield/production through complete automation and remotely controlled system.
  • Consume minimum water through recycling and repurposing the resource.
  • Have minimum geographical footprint.
  • Produce high grade washed Aggregates, Concrete and Plaster Sand.
Apart from providing a sustainable source of sand and aggregates, the plant will also have the following positive environmental impact:
  • Reduce 508 tons of CO2 emissions, which is the same as burning 250,000kgs of coal every year.
  • Save 9100 Giga Joules of Energy, enough to power 3000 Indian homes for an entire year.
  • Free 30,000 sq. yards of land from landfills, unlocking 100 crores worth of Real Estate every year.
The National Clean Air Programme (NCAP) aims at reducing particulate pollution by 20-30% by 2024 in about 122 cities which do not meet the National Ambient Air Quality Standards. Clean air action plans in these cities have included C&D Management as part of the clean air strategy. The other big development is the 15th Finance Commission’s direct allocation of Rs 4,400 crore to Urban Local Bodies (ULBs) for air pollution control. C&D Management is the direct responsibility of ULBs, and this funding can catalyse transformation in cities.

Surat Green Precast Private Limited (SGPPL)

Within a year of commissioning, Surat has already jumped to the 2nd position in the Swachh Survekshan rankings, which gives a lot of weightage to how a city handles its waste. In fact, the Surat Green story is one of the many successes that CDE Asia has achieved in their efforts to combat the problem of diminishing resources of natural sand through recycling and reuse of construction and demolition waste and also simultaneously solving the ongoing problem of waste disposal.

“CDE Asia is proud to have partnered with SGPPL for C&D waste management in the most effective way. The development of smarter, greener and sustainable cities will enable them to outgrow their dependence on natural sand, and thus help preserve and restore the ecological balance. It will also enable them to participate in a scientific process of repurposing waste to produce high-grade sand and aggregates made to exacting industry standards,” says Manish Bhartia, MD, CDE Asia.
