Glass disposal continues to be a headache for Central Otago WasteBusters.
WasteBusters general manager Glenys Byrne told the Central Otago District Council this week glass was the organisation's ''biggest problem''.
The quantity accumulating at the site was steadily increasing and that had serious implications for the organisation on staffing, fuel, vehicles and health and safety, for a very small return, Ms Byrne said in the organisation's submission to the draft annual plan.
The glass could be crushed but even crushed glass had to be disposed of.
The only buyer that converted used glass into new glass products was in Auckland and that agency had ''the whole of Auckland'' to supply it with glass bottles, Ms Byrne said.
Central Otago Mayor Tony Lepper said for most people, recycling glass bottles was the first move they made towards recycling ''... and we think we're doing a good job''.
Ms Byrne also aired her concerns about the ''uncertainty'' for the organisation, once rubbish collection moves from weekly to fortnightly on July 1.
''As we get closer to the changeover date, we're already experiencing an increase in volume in both the kerbside and rural recycling collections, and more noticeably, increased volumes and contamination rates at our rural depots and resource shop.''
There was also an increase in illegal after-hours dumping at the entrance to WasteBusters' base in Alexandra.
She was worried the predicted increase in demand for WasteBusters' service after the change to fortnightly collection was too low, which would lead to ''huge financial pressures'' for the organisation.
