The straps, which can be purchased at most hardware stores, have been an issue for the past 12 months because they become tangled in machinery at the SMRC’s recycling facility.
People wrongly think they can be recycled and put them in their yellow-topped bin.
Chief executive Tim Youé said the plant had to be shut down an average of 10 times a week while the machinery was cleared.
“The whole plant has to be stopped and the jam cleared before any more waste can be processed,” he said.
It takes staff at least 12 minutes to clear each jam and the stoppages cost the organisation about $150,000 per year.
However, Mr Youé said the straps were also dangerous for staff.
“Long pieces of strapping with metal ends that flick around could potentially come into contact with a staff member, causing them serious injury,” he said.
The straps cannot be put into green-topped bins either because they cause problems at the SMRC’s compost facility.
The best way to dispose of the straps is through verge collections or by taking them to a transfer station.
