Though not in its first year of operation, Sustainable Wagga's environmental education officer Sam Parsell said 2019 may prove the most successful.

Most of the council's plastic-free living sessions are nearing sold out with still 10-days left to register.

"It's just really starting to get popular," Ms Parsell said.

"People are really just realising how much of a problem plastic is having."

Plastic-free options are seeing an enormous uptake across larger cities in the nation, but Ms Parsell admits it has been a slower transition in Wagga.

"I went to a seminar recently where it was said that about 80 per cent of the plastic in the ocean has come from land-based activities," Ms Parsell said.

"I think inland communities are just making the connection that we contribute to that as well.

"We tend to focus on coastal ways, the turtles and the sharks, but our stormwater and our rivers travel into the oceans eventually."

Recent water level problems in the Murrumbidgee River, Ms Parsell said, has further advertised how environmental concerns affect inland centres.

"The water has been so low this year, we've had so many problems with its flowing I think people are seeing that freshwater has its own problems, let alone putting plastic down it," she said.

To emphasise the practicality of the plastic-free life, throughout July council will host workshops in beeswax wrapping and beauty product making.

"Both last year and this year the beeswax has sold out very early," she said.

"We still have a few places left for the pantry pamper session, which is about making your own beauty products.

"We'll be making a lip balm, a face cream, sugar scrub and green tea toner, out of things you could probably find at home.

"Most of these things, when you buy them they come in all this packaging that you then just throughout, but if you make it in a glass jar you can just replenish that over and over."

The trend towards plastic-free initiatives is encouraging, Ms Parsell said, following the results of a recent audit of Wagga's three-bin kerbside collection.

The audit, conducted last November, found the yellow-lidded recycling bins had a contamination rate of 12 per cent, higher than the 6 to 10 per cent national average.

It also found that 62 per cent of the rubbish thrown into the red-topped general waste bins should be disposed of in either the green-lidded food and garden organics bin or the recycling bin.

"A lot of the time we see recycling containers thrown into the general waste bins," Ms Parsell said.

"That means that there is recycling taking up room in landfill needlessly.

"Things like plastic cutlery or straws can't be recycled and if they do end up in the recycling bin they're small enough to get caught in the sorting mechanics.

"Another thing is litter, if it's on the streets it ends up in our river or drains and eventually gets to the ocean.

"What we're getting people to understand is that your rubbish is your problem."
