Main achievements:<br />
Significant technical and environmental documentation<br />
Declaration system established: classification,<br />
requirements to composition and quality control<br />
Official guidance is linked to NS-EN 206-1 (bound use)<br />
Included in the guidelines for road construction<br />
Raised the awareness<br />

Improvements:<br />
Product “declaration” => simple data sheet along with<br />
each delivery of recycled aggregates<br />
Stable delivery => often large volumes are needed<br />
which need to be extra planned in advance => may<br />
delay<br />
More knowledge about the “chemical composition”<br />
More commercial central recycling facilities =><br />
especially Road Authorities will take benefits of that<br />
since they do not own the waste<br />

Overall objective:<br />
To further increase the utilization of mineral waste in<br />
Indian cement and concrete industry in an<br />
environmental and scientific sound way by means of<br />
research based solutions and increasing the public<br />
acceptance and awareness of environmental benefits.<br />
Prioritised materials; CCR, C&D waste and slag<br />
