3.1.6 Quarry Dust Quarry dust, a waste product of the crushing process, is a concentrated material that can be used as aggregates for concreting, particularly as fine aggregates. The rock is crushed into different sizes during quarrying activities; the dust produced during the process is referred to as quarry dust and it is created as trash.

wind-blown dust can cause a significant nuisance to residential and commercial neighbours. The most common areas of complaint relate to dust on roofs, walls, windows, paths and gardens, and on residents' cars and washing. Neighbours may contact the quarry directly, but are equally likely to complain to their local authority.
