Unwanted bricks can be reused or crushed and recycled, minimising mining and quarrying activities and diverting waste materials from costly landfill.

Recycling bricks minimises the need for mining and quarrying activities to produce new bricks and diverts significant quantities of waste materials from landfill. Recycling bricks also results in cost savings for businesses through avoidance of landfill fees and transport costs, and through the reuse of bricks in other construction applications such as paving and landscaping.
Approximately 8 million tonnes of brick was disposed of (landfill and recycling) in Australia in 20051. If all of this were commercially recycled it would be the equivalent “everyday” savings of over 1.5 million households’ energy requirements for a month.

A number of commercial operators provide brick recycling facilities, such as bins and dumpsters, which can be placed on site (commercial, demolition or residential sites) for the collection and removal of bricks. There are also options for on-site crushing and reuse and central drop-off yards for unwanted bricks.
What Happens When It's Recycled?
Bricks can be recycled in two ways. First, they can be cleaned and reused in another building or project. Alternatively, they can be crushed into brick chips (for use as a landscape material) and/or finer particles (for use in manufacturing road-base, track and drainage material, fill sand or new bricks).
