More importantly , with the gangue instead of clay building bricks made , not only can reduce the gangue large accumulation of waste on land and water pollution caused by system resources , turning waste into treasure, made a lot of demand on the market more than the clay brick hard refractory bricks used in construction , and this can save land resources used clay brick , is the country, important projects benefit the development of circular economy .
