There are many benefits to recycling. The Latin meaning of the prefix “re” means: again; back, rearrange, rebuild, recall, remake or rerun. Recycling has not only become the right thing to do, it has become the requirement and a law in many cities and counties. Try demolishing a house/structure in many cities these days and you may find that there is a city requirement to divert at least 50% or more of construction/demolition materials from all county landfills. You will most likely be required to show receipts and documentation to the cities to get bond money back or to pull your next phase of permits. We can all expect 50% to turn into 80% plus within the next few years.
It is both amazing and awesome when you think about how many things are able to be recycled these days and re-used. Just a few that come to mind are rubber from used tires, drywall, paper and cardboard, cans/bottles, metals and steel of all kinds, plastics, wood and greenwaste, asphalt roof tiles and of course concrete and asphalt. Recycling helps our environment by keeping these materials out of landfills and taking up valuable space. It is usually less expensive to take items to a recycling center than going to a landfill or transfer station. You are contributing with your un-needed item/materials which will be beneficial and re-used in one way or another in the future. Canyons and valleys aren’t a renewable resource once they’re filled up. Solid waste dumps may make an awesome golf course, park or equestrian center one day once it’s filled up, but that garbage and material that can almost all be recycled nowadays will be there for hundreds, if not thousands of years.
Here are some of the benefits from taking concrete and asphalt to Greenstone Materials, Inc. instead of a landfill location, county dumpsite or transfer station:
- More often than not it is less expensive than a county landfill or a transfer station.
- We can help you with LEEDS (Leadership in Energy and Environmental Design) and compliancy paperwork if needed for possible job requirements.
- You get credit for 100% of the material (by weight) that you drop off to our recycling location. Concrete and asphalt are typically the heaviest items in demolition and construction.
- The material you drop off at Greenstone Materials is not buried as it is in a landfill, but crushed and recycled for re-use.
- Transfer stations end up taking concrete and asphalt to recycling locations such as Greenstone Materials, Inc. You are invited to bring it here to avoid middleman costs.
Here are a few reasons why recycled Class II/CMB grade base is a better choice as a base material beneath your structure, roads, paving, concrete, paving stones, flatwork, etc..
- When you purchase Class II/CMB grade base from Greenstone Materials, Inc., this material has been tested and approved by reputable paving/concrete geologists prior to this material making it to your site.
- The aggregate that was used originally in the asphalt and/or concrete had to be a superior/select grade product to be used in the first place. If this aggregate didn’t meet the specifications, it wasn’t able to be used as the aggregate in the concrete or asphalt in the first place.
- The cement from the concrete and oil/petroleum products in the asphalt form a catalyst when placed as road base, and is properly compacted with equipment and water. This helps bind and unite the base better in many ways than natural base is able to.
Some other interesting facts:
In March 1995, the City of Los Angeles passed a motion requiring that road base in all city projects include crushed miscellaneous base (CMB) with 100 percent recycled asphalt, concrete, except when site conditions or standards require another specification.
Construction and demolition waste materials make up about 22 percent of California’s disposed waste stream, or approximately 8.7 million tons.
Also in 1995, the Stapleton International Airport in Denver, Colorado, which had been in use for 66 years, was demolished. Most of the concrete from the demolition of the old airport was recycled. The recycled concrete was derived from 975 acres of runways, taxiways, service drives, and aprons with an average thickness of 23.6 inches. The total amount of concrete recycled, about six million tons, would have been enough to construct a two lane roadway roughly 995 miles long. The Colorado School of Mines conducted a study that found the recycled concrete from Stapleton was equal to or of a higher quality than virgin mixes. The Federal Highway Administration (FHWA), Federal Aviation Administration, Army Corps of Engineers, Environmental Protection Agency, State Departments of Transportation and many municipalities have approved standards for use of recycled concrete for road base. These statistics were over 15 years ago! The use of recycled base has become more and more of the norm due to the benefits and availability, along with continued education about this material. By using recycled base product, natural rock quarries are preserved for our future generations.
The Interstate 5 Improvement project in Anaheim, California sourced all of its aggregate from recycled concrete and asphalt. The six year project, which saw the freeway widened from three to six lanes on each side, required 800,000 tons of aggregate. The 100% use of recycled aggregate led to Caltrans saving US $5 million from not having to purchase and transport virgin material from a quarry.
