Glass is commonly thought of as a product that can always be recycled.
But did you know there are a few glass items we shouldn't put in the recycle bin?
Craig Mynott from O-I Asia Pacific, a glass recycling plant in Brisbane, said some glass needed to be excluded because it contained products that could not be reused.
"Microwave turntables, ovenware, crystal glass, mirrors and light bulbs can't be recycled.
"We prefer if people don't put them in the recycling bin.
"We just want to see bottles and jars in there."
Mr Mynott said dirty jars could also be harder to recycle.
"Jars that have contained food products we like to be rinsed," he told ABC Radio Brisbane's Craig Zonca.
"If they're not rinsed they are still used, but it makes our job easier.
How does the glass recycling process work?
Once glass is collected by kerbside pick-up it is taken to a sorting facility.
"It goes through a material recovery facility and then the glass goes to our recycling glass plant," Mr Mynott said.
"Then optical sorting technology is used to sort the glass into colours.
"We can sort down to glass that's eight millimetres in size and smaller stuff can be crushed down into a finer powder.
"Glass is 100 per cent recyclable and infinitely recyclable."
