At Martin, we’re paving the way to a more sustainable future by recycling and re-using materials
We’re Doing Our Part
We believe in and are completely committed to recycling/re-using products wherever and whenever possible. When we do demolition work, we can recycle materials such as asphalt, limerock, clay, fill and concrete and re-use them in future jobs.
Recycled concrete has many uses. For example, small pieces of concrete can be used as crushed stone, sand, and gravel for new construction projects. The Federal Highway Administration is using these exact methods to build new roads — from the materials of old ones. If free of contaminants, crush recycled concrete can be used as the dry aggregate needed to produce brand new concrete. Larger pieces of crushed concrete, such as riprap, are used commonly for erosion control.
Incredibly, with proper quality control, well-graded and visually pleasing recycled concrete can sometimes be used as a substitute for landscaping stone. Recycled crushed concrete can also be used as filler in wire gabions, then stacked together to form economical retaining walls.
The Benefits of Recycling
There are several advantages to recycling concrete:
- It prevents concrete debris from filling our landfills
- Using recycled concrete for gravel reduces the need for gravel mining
- Recycling one ton of cement saves nearly 1,360 gallons water and 900 kg of CO2.
- Using recycled concrete as the base material for roadways reduces the pollution involved in trucking material to the site
Both the American Society for Testing and Materials (ASTM) and American Association of State Highway and Transportation Officials (AASHTO) accept recycled concrete as a source of aggregate into new concrete.
