PNCC Water and Waste Manager Phil Burt says one of the glass recycling trucks is off the road for repairs following an accident on Park Road last week.
"We're committed to continuing our regular collection service but the temporary loss of the truck means that we have to work outside normal hours," he says.
Mr Burt says it will mean the team's other specialist truck will be out on the road for longer and an older truck from the Council's fleet is also being put into service.
"Please keep your glass crate out a bit longer as it may be collected in the evening between 5pm-8pm," Mr Burt says.
Mr Burt says the Council is hoping to hire an alternative specialised recycling truck while the repair work is being carried out.
