A Natural Resource - Marine Aggregates
What does the No1 Court at Wimbledon, Canary Wharf and Southampton Football Stadium have in common?
They are just a few of the structures that have been developed using marine aggregates. Although, aggregates - sand and gravel - are generally associated with mining quarries on the land, these days as much as 22% of the sand and gravel used in England and Wales actually comes from the seabed. There are increasing environmental pressures on land quarries - people feel that they permanently damage and scar the landscape. With this in mind, the marine aggregates industry is expected to play an increasing role in sustaining our built environment. However, to protect the marine environment, the removal of aggregates is very carefully managed. The Government, through the Crown Estate, apply strict licensing controls to the rights to take the minerals from the seabed.
