Environmental Uses of Aggregate
Aggregates are used in numerous environmental applications that protect and improve our environment:
- Drinking water and waste systems use specialty sands for filtering;
- Fluid bed smoke stack scrubbers use limestone to neutralize acid emissions prior to release into the atmosphere;
- Quarried limestone (agricultural lime) is used to improve agricultural soil condition and produce organic fertilizers;
- Aggregates are used to coat paper to make it white rather than using a chemical bleaching process to whiten wood fiber;
- Gravel is used to improve or create spawning beds for fish habitat such as trout, walleye and bass; and
- Quarried rock, in the form of rip-rap and gabion baskets, is used to protect shorelines from erosion and filter storm water basins.
