Waste Disposal
Since the 1980s disposal at sea of radioactive wastes (stopped in 1982), industrial wastes (1992), colliery mine-stone (1995) and sewage sludge (1998) has been progressively reduced, and is now prohibited. Only the disposal of dredged material from ports, harbours and marinas is presently allowed. This activity is essential to maintain navigation in ports and harbours as well as for the development of new port facilities.
Waste water treatment is designed to process waste water whilst protecting the environment and maintaining public health.
