			*Either way, after [[Demolition]] / [[Deconstruction]] , where tools such as [[Jackhammers]] / [[Hydraulic Breakers]] and other tools are used to break the Concrete (Structure) into manageable pieces, it is pushed into a pile / [[Roll Off Boxes]] or [[Dump Trucks]] etc

New page

=Basics=
*Concrete is one of the most commonly used materials
*HOWEVER it is largely made using newly mined materials, which is not only Unsustainable, but also presses challenges to a [[Circular Economy]] / Sourcing Materials
*This page aims to cover the Status Quo, the State of the Art (in terms of lower [[TRL]] Research / [[Pilot Plants]] etc and outline areas OSE could pursue Development / Further Research

=Internal Links=
*[[Concrete]]
**[[Asphalt Concrete]] / [[Rubberized Asphalt Concrete]] (Can largely be milled up, remelted, and recycled in place, due to the [[Asphalt]] essentially being a [[Thermoplastic]]
**[[Asphalt Millings]] can be downcycled as a [[Construction Aggregate]] or [[Gravel Road]] material, albeit with some [[Micro/Nano Plastics]] (for the latter) + Hydrocarbon Leaching concerns for both
*[[Portland Cement]] / [[Fly Ash Cement]] based Concrete
***More common/conventional Concrete, however more complex to recycle, short of downcycling to aggregate
*[[Rebar]]
**[[Steel Rebar]] should be easily separated via [[Electromagnetic Separation]]
**[[Fiber Reinforced Polymer Rebar]] / [[Fiberglass Rebar]] / [[Carbon Fiber Rebar]] present some challenges in terms of M/NP Pollution, as well as difficulties in separation
***[[Thermal Recycling]] such as in a [[Calcining]] step may suffice
*[[Concrete Aggregate]] / [[Sand]]
**For information on Aggregate Parameters
