CONCRETE RECYCLING ROBOT
ERO is a Concrete Recycling Robot designed to disassemble concrete structures and enable the building materials to be re-used for new pre-fabricated concrete buildings. Current techniques of concrete demolition requires a lot of power crushing, separation and machinery. Not to mention waste of water in order to prevent dust pollution during operation. Transferring waste material to recycle stations outside the city wastes time and the end result of which can only be re-used in very limited areas. ERO uses water jets to crack the concrete surface to disassemble concrete and sucks up the mixed debris. It cleanly separates the waste mixture and packages the cleaned material. What was previously waste, now turns into labeled packaged asset to be transferred right away into concrete pre-casting stations to be re-molded into new building blocks. No dust, no waste, no separation. Only clean bags of aggregate and rust and dust free rebar remains to be cut and re-used directly.
One of the goals of this project was to provide a smart & sustainable near future approach to the demolition operations that will allow re-using as much as possible.
Today, operators manually control different sized heavy machinery to smash and crush the concrete structure into dusty bits. All of these machines consume a lot of energy to operate. Water has to be sprayed constantly with fire hoses to prevent harmful dust from spreading around. After the work is done, big machines scoop up the rebar and concrete mixture and transfer them to the recycle stations outside the city. There, the waste needs to be separated manually. Concrete needs to be crushed with power crushers in several stages, end result of which can only be used for simple construction layouts. The metals are melted to be re-used. These operations all require heavy machinery.
An autonomous fleet of ERO is placed strategically within the building. They scan the surroundings and determine a route with which they will execute the operation. Once ERO starts working. they literally erase the building. ERO de-constructs with high pressure water, sucks and separates the mixture of aggregate, cement and water. Then sends aggregate and filtered cement slurry separately down to the packaging unit to be contained. Clean aggregate is packed into labeled big bags and sent to concrete pre-cast stations nearby for re-use.
Water is re-cycled back into the system, ERO doesn't waste water like today's systems. Packaging unit provides ERO with vacuum suction and electrical power. Turbulence dynamos placed within the air suction route which produces some percent of power ERO needs. ERO uses less than what it gets. Nothing is land filled or sent away with extra operations. Rebar is now cleaned from concrete, dust and rust. It is ready to be cut and re-utilized immediately. Every bit of the load bearing structure is reusable for new building blocks.
This project is an excellent solution for the complexity of today's demolition techniques which consumes a lot of energy to create a lot of waste. All around the world concrete is being demolished increasingly to make new ones every day. ERO simply turns Waste into Asset.
