WHY
2
Recycling of end-of-life concrete reduces environmental impact, dependency on raw materials, concrete price fluctuations, and landfill demand. This technology enables the final step, separating the 0-4 mm fine fraction, in an economically viable and sustainable way.
HOW
1
A Heating-Air classification System (HAS) simultaneously heats, grinds and separates the concrete in fluidized-bed-like conditions. This weakens the bond between silica and cement paste, allowing the production of clean sand and cement clinker-type products.
WHEN
TRL
This technology completes earlier TU Delft recycling innovations (i.e. ADR). The project will upscale the lab scale facility to an economically viable 3000 kg/hour system, using its output to construct 100% recycled concrete buildings at The Green Village.
