Planning permission for a controversial waste incinerator on the outskirts of Belfast has been refused.
Arc21's proposal for a recycling plant and incinerator would have created more than 300 jobs, but will not go ahead.
The £240m proposal at a former quarry in Hightown would have taken waste from 11 of the former council areas in Northern Ireland.
Environment Minister Mark H Durkan said he was not satisfied the development would not cause harm to human health.
"Therefore I consider the development should be refused," he said.
"This development could result in an increased market for waste disposal and to maintain a facility such as this, in addition to the other approved waste facilities, could discourage recycling.
