Up to half of coarse sediments on UK urban beaches may be human-made, study suggests

Researchers say waste dumping and climate breakdown have contributed to rise in brick, concrete and glass on beaches

As much as half of some British beaches' coarse sediments may consist of human-made materials such as brick, concrete, glass and industrial waste, a study has suggested.

Climate breakdown, which has caused more frequent and destructive coastal storms, has led to an increase in these substances on beaches. Six sites on the Firth of Forth, an estuary on Scotland's east coast joining the River Forth to the North Sea, were surveyed to better understand the makeup of urban beaches".
