The Manufacturing Process

The manufacture of house bricks generates a significant percentage of bricks that do not meet the rigorous quality standards required for house building, for instance because of cracks or other damage and are scrapped. These cannot easily be reprocessed and they are set aside and crushed for use in other applications, e.g. as lightweight aggregates or for use as green roof growing media.

Green Compost

Where the Growing Media incorporates Compost it is derived from a sustainable source, normally 'pine bark' Compost.
