The fact that it is more expensive:
Fortnightly bin collections are to be extended across the country to save money.
We already have the taxes in place to cover the externalities of waste disposal: landfill tax for example.
So, if recycling did indeed save resources as a whole, given that we\’ve already internalised the externalities, it would be cheaper to recycle than it is to simply landfill. That it isn\’t shows that recycling is not, over the whole system, saving resources.
Thus these moves to save money by reducing the collection service.
