Concrete made with recycled glass could soon be seen on Canberra construction sites, after a recent upgrade of the ACT's main recycling centre.

More waste will be sorted and broken down even further as part of an $8 million improvement to the Materials Recovery Facility in Hume.

The upgrade was shown off to the public on Saturday as part of the centre's first open day.

As part of the works, glass bottles processed at the facility will now be able to be turned into a sand, which can be used in road bases and concrete mixes.
