Cantabrians got a glimpse behind the doors of Christchurch's recycling and waste facility at a recent open day.
It was the first opportunity to see how the $17 million investment was spent.
A number of high-tech sorting machines using state-of-the-art optical sensors to identify the recyclables from the rubbish have been installed at the plant.
EcoCentral chief executive Craig Downie said: "And that's important because that means that the manufacturers that use recycled product will take our product as a priority and it has value."
