Valuation of Aggregate Operations for Banking Purposes (Sand and Gravel and Crushed Stone) Aggregate consists of sand and gravel and crushed stone. The principal consumers of sand and gravel and crushed stone materials are the highway and building construction industries. The principal construction uses include:
Aggregate is mined from the earth, either dug out of pits or blasted out of quarries. This process has many significant environmental impacts. Creating the pits or quarries requires the removal of virtually all natural vegetation, top soil and subsoil to reach the aggregate underneath.
By setting taxes on aggregates extraction to create incentives on alternatives. The current situation will continue unless sand extraction is correctly priced and taxed so that other options become economically viable.
Aggregate industries have raised much controversy within communities due their extracting methods. Through the extraction of aggregates, landscapes are altered which effect ecosystems that contain numerous species, including humans. Water and noise pollution are extensions of aggregate extraction.

Stone quarrying is the multistage process by which rock is extracted from the ground and crushed to produce aggregate, which is then screened into the sizes required for immediate use, or for further processing, such as coating with bitumen to make bituminous macadam (bitmac) or asphalt.
This in turn reduces the environmental impact of the aggregate extraction process. By removing both the waste disposal and new material production needs, transportation requirements for the project are significantly reduced.

The most obvious harmful direct effect of marine aggregate extraction results from the direct removal of substrata and associated benthic epifauna and inflora. Available evidence indicates that dredging causes an initial reduction in the abundance, species diversity, and biomass of a benthic community.

To make a site cost-effective companies have to ensure that the full potential of the site's deposit is extracted or return to previously worked deposits using techniques and plant that are efficient for the task. Accordingly, the use of dredging as a method of underwater extraction of sand and gravel has become more commonplace in the UK.
