Sand Extraction an overview ScienceDirect Topics

Offshore sand and gravel extraction involves the abstraction of sediments from a bed which is always covered with seawater. This activity started in the early twentieth century (in the mid-1920s, in the UK), but did not reach a significant scale until the 1960s and 1970s, when markets for marine sand and gravel expanded and dredging technology improved (Figure 1).

The search for sustainable sand extraction is beginning

Most sand goes into the production of cement for concrete (which is made of cement, water, sand and gravel). Cement, a key input into concrete, the most widely used construction material in the world, is a major source of greenhouse gases, and accounts for about eight per cent of carbon dioxide emissions, according to a recent Chatham House report.
