Recycled Concrete: The Pros and Cons - Braen Stone

Recycled Concrete Aggregate At-A-Glance. When a concrete sidewalk, road, parking lot, or structure needs to be excavated and replaced, the concrete is often discarded into a landfill. Because chunks of concrete are not biodegradable and are unable to decompose over time, the waste takes up a great deal of space and creates environmental concerns.
