Once upon a time old concrete went into land fill but that's less common in this more environmentally conscious era. Concrete Recycling presents a number of benefits for property owners, construction companies and the planet. For a start land fill space is not unlimited and land fills are not welcoming concrete rubble any more. Secondly the reuse of concrete material in construction saves considerable reserves of aggregate particles like sand, gravel and other basic materials that have to be excavated from the ground. But also with the possibility of local or even on-site recycling it becomes possible to save the resources involved in trucking large amounts of heavy material around the country for burial.
Recycling saves money. That's because the costs of transporting and disposing of old concrete are rising every year. The weight of concrete rubble means that transporting it can cost up to twenty five cents per ton per mile. With an increasing number of land fills now refusing concrete rubble the distances to cover are going up and the customer has to pay that. Even when a land fill site is prepared to accept concrete waste the costs of disposal can easily be a hundred dollars per ton. Again that price is passed on to the customer. Recycling saves those costs. Talk to Birmingham Concrete Removal about the numbers.
The Process of Recycling
To make new concrete out of the old we first have to pulverize it with a crushing machine. Crushing machines come in different sizes tend to be big, heavy beasts but a generation of smaller portable crushers means that they can now be brought directly to the building site where the old concrete is being demolished and removed. In order to be used the crushed concrete has to be free from leaves, paper and other debris so we need to filter it and in the case of reinforced concrete extract any rebar using magnets. Then it is ground down to a specific particle size depending on the intended use.
Good for the Planet
You might think that construction basic materials like sand and stone are pretty much worthless and unlimited but demand for construction means there are shortages in the materials used for concrete aggregate. Carving them out of quarries makes no sense when the old concrete can be reused so just like we'd recycle our glass bottles we should recycle our old concrete.
Good for Business
If you're just laying a bit of pavement all you need to know is that recycled concrete is every bit as good as new and crushing your old concrete to reuse saves you twice – once on the costs of haulage and land fill for the old concrete, and then again in money saved on the cost of materials used. If, however, you're constructing a building and looking for LEED Green Building Certification then you will be happy to hear that using recycled concrete in your construction can win you points.
