Couldn't agree more with Dave's comment.
As far as I am concerned I think there is much too much primary sorting of the rubbish. It is possible to construct a sorting machine that will sort almost any substance from another. Such machines could be built to benefit from economy of size and with a throughput that would make the local recycling centre look the size of a pimple on an elephant's backside. This could only be done by a countrywide agreement to enter the system, so it must be a Central Government initiative.
The number of boxes and the issue of what happens in the wind is recognised as a problem and a weak link in the current solution.
There is a sorting machine at Gofer site to seperate the plastic and different metals.
By keeping the paper seperate, it means it is not contaminated and the Council acheives a better premium from Shotton Paper Mill.
Speaking with Cllr Mike Priestley yesterday, I understand that a trail of the new box system should be available in March. Later than expected due to finding funding (i.e. not from the Council Tax)
