Is it an unrealistic challenge in a world where there is plastic in every isle of the supermarket?

Anambah couple Mark Brown and Kate Beveridge took on the challenge for Plastic Free July - and they succeeded. But their success didn't come without having to give up three of their favourite foods, which are wrapped in plastic.

Ditching plastic wasn't an overwhelming task for this duo. They are already environmentally conscious and have been reducing their use for years, but it did force them to think creatively.

They grow all of their own vegetables, so that gave them a good head start.

"It was a challenge because we are vegetarians and some of our meals are based around tofu, tempeh and cheese, which were all wrapped in plastic," she said.

"To do without those three sources of protein was quite hard, but it just made me more creative. We make our own pizza and I didn't have grated cheddar cheese for the pizza, but we survived."

Doing the shopping without buying anything wrapped in plastic meant Ms Beveridge had to go to three or four different shops. She made time for things like making bread and yoghurt - and making her own laundry liquid.

"It's about getting into a rhythm, it's not time consuming for me to do these things. I'm up at 7am or earlier and we don't finish on the farm until 6pm at night," she said.

"We all have the same amount of time, there is 24 hours in a day, it's about how we use that time. Maybe I'm not sitting down to watch TV, I'm putting the bread on instead, or making my yoghurt in the morning instead of sitting and having my cup of coffee."

The venture is also saving her money.

"Go back to that frugal way of doing things that our grandparents used to do because the resources weren't available," she said.

Here are some of Ms Beveridge's tips:

DAIRY

Buy a glass bottle of milk and used it to make biodynamic yoghurt.

"If you buy a glass bottle of milk, even if it is a bit more expensive, you'll get two jars of yoghurt out of that for less than it would be to buy a tub of yoghurt," she said.

"I was making it for 50 cents rather than paying $6 or $7 for it at the supermarket," she said.

"I make 3 litres of yoghurt at a time so I don't have to do it very often."

When it comes to cheese, look for it in a glass jar. "I bought some fetta in a glass jar, it was more expensive but it made me appreciate it a lot more," she said.

BREAD

Make your own bread so you don't have to buy it in plastic.

"It is possible to make it and put it in the oven before you have breakfast and get ready for work in the morning," she said.

If that isn't achievable, there are some artisan bakers where you can buy one that isn't wrapped in plastic.

WASHING:

Laundry:

Make your own laundry liquid and save money. Nine litres costs her just $4.50 to make.

"It costs me 50 cents to make a litre of laundry liquid and I make 9 litres at a time so I don't have to make it every often," she said.

Dishwashing:

"I've got a soap dispenser with a little metal hole that you shake under the water so I don't have to buy dishwashing liquid in a plastic bottle," she said.

General cleaning:

"I make my own cotton dish cloths so I don't have to buy plastic based ones," she said.

Re-use plastic that you have, including plastic cleaning utensils, until they wear out and have to be replaced. Then buy an eco-friendly replacement.

"I had to replace my plastic bottle cleaner so I bought a wooden one with bristles and when it needs to be replaced I can put it back into the earth," she said.

PERSONAL CARE:

Deodorant:

"I make my own deodrant because I was really concerned about the number of plastic deodorant containers I was getting," she said.

"A friend gifted me a jar of deodorant and I thought ' I can make this'. It's actually very easy."

Shampoo:

Use a shampoo bar, which is similar to a bar of soap, or wash your hair with bicarb soda and rinse it with vinegar.
