C&D Waste Scenario

Construction industry in India is growing at twice the world

average. Total construction market in India (PWC Estimates) for

FY 14 was over Rs. 900,000 crores. This creates sizable C&D

waste.

It is estimated on a conservative basis that over 25-30 million tons

of C&D waste is generated annually that clogs rivers, blocks

traffic and occupies dumping space

Size graded aggregates, manufactured sand and cast products are

the outputs which have great potential to replace natural

materials and address shortage of building materials

The first plant at Delhi (Burari) has shown that there is huge

potential of recycling and value addition

Heterogeneous Nature of C&D waste

Generally C&D waste is mixture of many components hence makes its recycling more complex

C&D Waste Management : Scientific Sustainability

Processed over 17 lakh tons of C&D waste since its inception in 2009, which would

otherwise have been dumped illegally in the river Yamuna and other environmentally

sensitive areas

Saving of about 11 hectares of land

costing app. 256 crores(as per circle rates)

A unique large scale C&D recycling facility in the

Country, compliant with MSW, 2000 Rules

Engineered to process mixed Indian C&D waste

Reduces usage of natural resources and enhances

conservation

Reduces sand mining from river banks

Washing water recycled, only 10-15% makeup water

Reduces burden on the landfill sites, saving precious

urban land

Reduces air pollution

Unique Collaborative venture with DDA for Constructionof Pilot 100m wide Express road connecting NH-10 &Bakkarwala using processed C&D.

The 10 KM long road is being built as per specificationsand supervision of CRRI.

Size of C&D aggregates proposed to be used in this PilotRoad project is -150mm to +26.5mm. About 6 lakh tonsof processed C&D will be used in making of the PilotRoad.

Advisory : Usage of Recycled Products

Regulatory Challenges

Lack of National Standards and regulations

Draft SWM Rules 2015 have incorporated detailed management of C&D

waste (expected to be notified soon)

Bureau of Indian Standards (BIS) is working on fast track mode but final

Standards yet to be notified

Market development is very important
