Concrete recycling vs concrete disposal. There are two ways to deal with old concrete: recycle it or dispose of it. Just looking at the cost to recycle concrete it is much lower than the cost to dispose of it. Recycling concrete costs around $4 -$10 per ton. Disposing of concrete can cost as much as $22-45 per ton!
