Re: Repair != Green
Maybe running out of landfill space?
All of the millions of tonnes of minerals used in infrastructure maintenance and construction are dug out of the ground, so there's no shortage of holes to fill, other than in places where they either don't mine the aggregates, or where they fill with water like the Netherlands. There's some minor local landfill shortages (eg South East of England), but even there there's another option, landrise. Which is where you keep on filling a landfill vertically, until you have a small hill. No different to the spoil heaps left by mining, except that these new ones are to much tighter environmental standards. A good example is the Packington landfill near Birmingham airport. That;s gone from a gravel pit to a 250 foot hill. Soon it'll be grassed over, and be returned to nature or leisure use, whilst still producing methane for power generation for the ext couple of decades as the site is now closed other than for the reinstatement.
would you really want your new home or childs school built on one - or on a nuclear waste dumping ground
No, but that's a weak and spurious argument. The total land area of landfills and nuclear waste sites is trivial compared to the UK land mass. Plenty of other land to build on.
