1. Effective Management of Construction & Demolition Waste In Urban & Semi Urban Areas

2. Introduction Composition of C&D Waste India scenario Regulatory Framework C&D Waste Processing Facilities in Delhi Process Flow Value Addition of Processing Success Stories Pilot Plant Installation Way Forward Index

3. Introduction Total construction market in India (PWC Estimates) is over Rs 900,000 crores. Construction industry in India is growing at twice the world average. Construction Industry likely to face material supply issues and rise in prices of construction material. A strong emphasis must be put on resource efficiency, use of alternate materials and C&D waste recycling. In 2018, annual generation of C&D waste in India 100 Million MT. Delhi generates about 7,000 TPD of C&D Waste.

4. Estimated annual consumption of construction materials in India are as follows: Sand : 750 million tonnes Soil : 123 million tonnes Stone (aggregate) : 2000 million tonnes Over 5 % of the construction material requirements can be met through C&D recycled materials. Introduction Source :As per NITI Aayog Report on Strategy on Resource Efficiency in Construction & Demolition Sector, Jan 2019,

5. C&D Waste consists mostly of inert and non-biodegradable material having high density Major Components Cement Concrete (Demolished) Broken Bricks Broken Cement Plaster Steel Rubble Broken Stone Broken Timber & Wood Soil & Sand Gravel About 70 % of C&D waste comprises of mixed sand and soil Composition of C&D Waste

6. Estimated Quantity of C&D Waste Generation as per Technology Information, Forecasting & Assessment Council (TIFAC) : 40-60 Kg per sqm of New Construction 40-50 Kg per sqm of Building Repair 300-500 Kg per sqm for Demolition of buildings These estimations to be revisited based on recent modifications in specifications As per the recent IIT Kanpur study on air pollution and GHG emissions in Delhi, PM (PM10 + PM2.5) emissions on account of C&D waste is 6.5 tons/day or 2,372 tons/year India Scenario

7. Possible to optimize over 95% recycling of mixed C&D waste by using mix of dry and wet processes Size graded aggregates, manufactured sand and cast products are the outputs having great potential to replace natural materials and address shortage of building materials Processing of C&D Waste

20. The aggregate performance was found stable throughout the assessment period of 5 month. The acid soluble part was 5-8% and 12-16%. The dissolved silica content and the reduction in alkalinity were used to assess the alkali aggregate reactivity (AAR). Some expected variations in mechanical strength performance were found and some of the aggregate crushing values were above 30%. Assessment of Technical Properties of Recycled aggregates from mixed C&D waste

21. Mechanical strength (e.g. LA abrasion) was found satisfactory for bound use (e.g. concrete applications) and unbound use (e.g. road construction). Water absorption varied, as expected, due to variation in the feedstock. Recycled aggregates produced at Shastri Park are suitable for a range of user applications like concrete block production, tiles, road constructions etc. Assessment of Technical Properties of Recycled aggregates from mixed C&D waste

30. Project Scope

31. Processing of C&D Waste

32. It will be worth mentioning here, that so far, these projects have processed approximately 80 lakhs tons of C&D waste till date since their inception. This endeavour has been well appreciated by Ministry of Urban Development ( MoUD ) and has asked all states to look into the possibility of installing such facility in cites having population above 10 lakh. The major purpose / objective of this activity is to separate C&D waste from MSW stream and to reuse & recycle C&D waste into useful building material. This will in turn help improve the life of such landfill sites. Recycling of malba will save natural resources and improve ecosystem. Project Benefits

33. S. No. Particulars Details 1. Air Quality Management Wet processing significantly reduced dust generation and have a very minimal impact on ambient air quality Water sprinklers are used during unloading and operations. 2.
