A separate glass recycling scheme for Christchurch could cost ratepayers up to $1.4 million extra each year and will negatively impact climate change, a council report says.
But two city councillors who are pushing for the scheme to go ahead, have dismissed the report’s findings.
Crs Phil Mauger and Aaron Keown called on the council in November last year to look into the possibility of the council implementing a glass recycling scheme where residents would put glass in a separate bin.
Presently, Christchurch residents are supposed to put glass into their yellow recycling bin. Any glass put in these bins is later crushed and then mixed with shingle at a quarry, which is eventually used in a road subbase.
At best, it would cost $610,671 per annum, over and above the existing scheme, but it could be as much as $1.4m depending on how much glass was recycled through the CRS instead.
CRS would encourage people to return bottles and cans for recycling by including a refundable deposit in the purchase price.
Some advantages of a separate glass collection were highlighted in the report, including the fact that a higher price could be obtained for paper and cardboard collected at the kerbside because it would not be contaminated with glass.
