A looming statewide ban on single-use plastic bags in WA is forcing many people to think about how they will break a long-established habit the next time they go shopping.

So imagine not using any single-use plastics at all.

No plastic straws, cups, plates, cutlery, cling wrap or takeaway containers, and no plastic packaging for chips, muesli bars, cereals, other foods and kitchen and bathroom products.

It can seem daunting, overwhelming, inconvenient and expensive all in one.

The message from people who are trying to live free of single-use plastics is that it is easier than it seems — but they say people should not try to cut them out completely in one go.

Rather, take it one step at a time.

Homegrown spinach and stainless steel straws

"Since then, we've gone on to use the stainless steel straws, reusable cupcake cases," she said.

"I now have a Sodastream maker, so I don't have to buy soda water in bottles."

Ms Thomas, who lives in the Perth suburb of Bassendean with her husband and two young children, grows her own spinach and herbs to avoid supermarket packaging, and no longer puts packaged foods in her children's lunchboxes.

"It's actually a lot easier than you probably think," she said.

"To make a batch of 12 muesli bars probably takes me 10 minutes in the kitchen."

But it is far from easy to stop using single-use plastics altogether.

Some items, like punnets of strawberries, which she and her daughter Macie love and do not want to give up, are hard to readily find without packaging.

Six years since plastic-free pledge

To live completely free of single-use plastics takes time.

Lindsay Miles took up the challenge six years ago after seeing a poster promoting a plastic-free July challenge.

She said she reached her goal after a few years and it had become part of her routine.

"I guess some things are more expensive, some things are cheaper. For me, overall, it's balanced out," she said.

Ms Miles said she made one change after another and never stopped.

"One of the biggest things if you want to avoid plastic is to buy stuff second hand, so you're avoiding the packaging," she said.

Ms Miles also makes a lot of her own food from scratch, and buys local produce when she can.

'Look at what's in your bin and pick an item'

Bulk food shops are also becoming increasingly popular as people try to avoid being left with a bin full of plastic.

Co-owner of The Wasteless Pantry in Mundaring, Jeannie Richardson, said people lived with much less single-use plastic 40 or 50 years ago — and they could do it again.

"It wasn't always like this. There is a way, and it doesn't have to be difficult and it doesn't have to be expensive," she said.

"Don't feel bad that you haven't gotten rid of it and you're not a zero waster and you can't put your waste in a jar at the end of the year.

"Choose one thing, look at what's in your bin and pick an item and think, 'OK, how can I get rid of that this week'."

And the following week, choose something else.
