Structures made of concrete are demolished everyday and can create large quantities of rubble and waste. This excess is usually dumped at landfills, requiring expensive disposal and environmental costs. While disposing rubble is everyday business for most companies, recycling concrete could be a beneficial alternative in aiding company budgets and community landscapes. Concrete recycling is utilized when debris is collected from demolition sites and processed through mobile concrete-crushing machines. First, the aggregate is gathered and sorted, leaving any trash, wood, paper, metals, and rebar out to be melted. Then, processing machines are used. Large crushing machines process the debris at 600 tons per hour, while smaller machines crush debris at 150 tons per hour. Remaining chunks are sorted by size, with any large chunks to be reinserted onto the conveyor belts of the machines.
Disposing concrete can have its drawbacks. Hauling and disposing concrete can be expensive at twenty-five cents per ton a mile and disposal can cost a hundred dollars per ton. Also, landfills will have restrictions in the aggregate you are disposing of Recycling can save money and it can also be environmentally friendly. Keeping concrete out of landfills can save space. Reusing gravel can reduce gravel mining. A ton of recycled concrete can save 1,360 gallons of water. The leftover aggregate can also be used for city and community projects. Pieces of concrete can build new paths and walkways for pedestrians. It can also be used for retaining walls for sloping hillsides to control erosion. And if placed surrounding wet areas, pieces of broken-up concrete may be used as material to help drainage. Recycled pieces of concrete can also help home projects in raising garden beds and terraced gardens.
The U.S. Federal Highway Administration have been long-time proponent to recycling concrete and have been using old material to build newer highways. It’s possible the highways you drive on now have been built upon aggregate of a highway that existed once upon a time. The 300,000 square foot Spectrum Commerce Center in Minnesota was built upon concrete that were formerly part of two rental car garages. So there are many ways concrete can be re-purposed. Recycling can benefit home and industry and can keep construction and transportation costs down. On a final note, it is important to always choose the right cutting solutions for your concrete recycling projects. Gila Tools Inc, offers a variety of options depending on the job.
