- Too many steps are involved during current techniques.

- Steps are too complex, time consuming and requires a lot of energy.

- End result of operations have very little re-useability

- In city Transport is expensive and hard to operate because of trafc.

- How might we produce Assets instead of Waste material?

- There is a scarcity of raw materials, energy, water and landll areas.

- How might we keep things happening within city walls?

- Transporting heavy machinerty is always costly.

- Separation Process is done manualy and with heavy machinery.

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 rehoses 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.

Hydro demolition is a technology tat is used today for scarifying or d

repairing or to get rid of it. Even though it doesnt recycles water it stconcrete building blocks are also very efcient way of constructing ndisturbance to its surroundings. The idea of ERO sprang after my re

experiences in the construction eld. Instead of using brute force to sand get clean material out for re -use. Could we recycle the water an

RESEARCH & CONCEPT DEVELOPMENT

First phase of the project was the usual research phase. After interviewing eld engineers and a recycling companyrepresentative I have arranged some eld trips into Moscow(Russia), Vienna(Austria) and rebro(Sweden). Moscowis one of the worlds fastest growing city and there I had the chance to interview ofcials and take video footagewithin highly prestigious construction sites to examine in detail afterwards. Then I have consulted mechanicalengineers and some marketing people in Sweden and Austria and had the opportunity to learn the base mechanics.

During the second phase of the project, I have started to develop scale mock-up models, sketching, software animated simulations athe inner basis for the nal result. The technology was there so I hsolution purposes of the project. I also have re-consulted designehave tried to stick with the existing technologies and adapt them a

MAIN FEATURES

ERO is a Concrete Deconstruction Robot designed to disassemble reinforced concrete structures

and enable the building materials to be r e-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 i n order to prevent dust pollution during operation. Transferring wastematerial 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. Itthe cleaned material. What was previously

transferred right away into concrete pre-castNo dust, no waste, no separation. Only clea

free rebar to be cut and re-used directly.

ERO uses, Hydro demolition, Centrifugal Decanter as its separationtechnologies. Hydro demolition is used today to scarify or to get

rid of concrete for repairment reasons. It attacks the micro-crackson the concrete surface with high pressure water jets and make it

come apart. This way you dont damage the rebar while applying

hydraulic brute force to pulverize but peel off the concrete smartly.Hydrodemolition usually wastes a lot of water ecause it does not

separate and recycle the water . That is why ERO uses CentrifugalDecanter as a separation tool. Centrifulgal decanter is a separation
