Recycling
Demolition of a building:
is it just a pile of rubble
and waste?
The benefits of MB Crusher units towards Green Demolition
“Nothing gets thrown out! Is a lesson we have learned from our grandparents. Any scrap, can be reused, changed or repurposed to become something different. To though something out is a waste, to waste something means to lose money. In short, circular economy has always existed.
All above concepts can be applied to demolition processes, moreover when we demolish to requalify, redevelop or rebuild. Nothing gets wasted. Material is selected, processed as necessary and then reused, directly on-site or somewhere else.
A company in Spain understands this well, having recently demolished its old shed, to then build another one in its place. "Our demolition process was much more than breaking down the shed," they stated, "it was like destroying a building made with Legos and then using the same bricks to build a new one. So, we did. What we demolished, we reused for the most part to redo the building. The bulk of the work was done by the MB Crusher’s crusher bucket, with which we crushed the inert materials to reuse them as the basis for the new shed. The job was carried out with a single heavy machine, and with a single operator, at the same yard, quickly and with a minimum investment."
Building demolition: Waste only? NO, in fact, demolition is a process made up of various steps— time and cost— that represent the basis of a change. And if the demolition is done correctly with the right machinery, it became a great advantage for the company carrying it out. Sufficient to say,
sustainable demolition saves about 80% of the waste from the landfill. Selective demolition—green demolition or deconstruction— it might seem more expensive, time consuming, more demanding. In reality, it saves money, time, and tax benefits.
In France, a company managed to recycle almost all the demolition debris of an old house and reuse them to build the new one directly on the same spot, forgetting all the logistics and disposal problems.
In Turkey, one excavator and one operator recovered and recycled the road demolition material – a mixture of basalt and asphalt— directly on-site and at a very low cost. How? By attaching a BF90.3 crusher bucket to his excavator, which
