The first green waste bin collections have taken place in Weston this week, as part of the ACT government's green waste bin pilot program.

The pilot program will cover suburbs in Canberra's south, including Chapman, Duffy, Fisher, Holder, Rivett, Stirling, Waramanga, Weston and Kambah.

Minister for Transport and City Services Meegan Fitzharris said since the delivery of the first bins in mid-March, more than 6000 residents have taken up the new JJ Richards service for a one-off fee of $50.

Green waste accepted in this bin include lawn trimmings, garden cuttings and leaf litter. Specific directions on what can and cannot be placed in green bins are found under the lid.

"The popularity of the green bin take-up in Kambah and Weston Creek has shown how important this type of service is to the community and I look forward to seeing it extend to the rest of Canberra over the next three years," Fitzharris said.

"This program will reduce the impact of green waste ending up in Canberra landfill. Waste collected from green bins will be processed, recycled and made available through commercial providers, offering a more environmentally sustainable outcome for green waste in Canberra."

The proposed roll-out schedule for other Canberra suburbs will begin in Belconnen and Tuggeranong in mid-2018, followed by collections in Central Canberra, Woden and Molonglo from mid-2019. Collections in Gungahlin and Hall are schedule to start from mid-2020.

And this is just the beginning. Fitzharris told The Canberra Times a separate food waste collection service is "on the government's radar", with ACT NOWaste director Michael Trushell revealing that a recent national roundtable discussion had fleshed out the idea.

"There is tremendous opportunity in that space," he told the newspaper.

"If you get organics out of your landfill waste you have less issues around odour, leachate and less methane being generated."

However, Trushell noted that while it is important to look at new strategies, it is still early days and any future launch will require national cooperation and testing to determine how the public adapts to source separating its waste.

He added that community education is a priority in any opt-in service and necessary for future food waste separation policy.
