Offshore waste incinerators

There will always be some waste which cannot be avoided or recycled. This is either put into landfill or incinerated. Both landfills and incinerators tend to be opposed by those who live nearby because of smell from landfills and fears of trace toxins (usually dioxin) and the consequent drop in property values from incinerators. But this stuff still has to go somewhere. Simple solution: build waste incinerators on offshore platforms and cart the waste out to them in barges. They don't have to be very far offshore, as long as they're out of sight. By the time any toxic emissions reach land they really will be diluted to insignifigance. This will be an expensive way of getting rid of waste, but it's up to people to decide how much they want to pay to dispose of rubbish: pay X amount per year for an offshore incinerator or save money by building an incinerator on that vacant plot next to the primary school.

I realise this isn't going to be very practical for places which are far from the sea, but I think I read somewhere once that 75% of the world's poulation live within 50 miles of the sea, and most of the world's big cities are on the coast or estuaries.
