When it comes to living sustainably, it can be hard to know where to start.

Plastic packaging covers supermarket shelves like a heat rash, recycling is harder than a game of go fish, and don’t even get me started on fast fashion.

But it doesn't have to be hard.

Watch: 7 eco-friendly habits that aren't so green... Post continues below.

Here are some back-to-basics tips that will help the planet, and won't break the bank.

1. Plastic-free periods.

Before you keep scrolling, hear me out.

It takes on average 400 years for a pad or tampon to break down in landfill, many often ending up in our oceans. Yikes.

Just like no two periods are the same, everyone tackles a plastic-free period differently. From moon cups to period undies, there are so many options now that there's really no excuse. (Check out what theMamamiateam had to say about period undies here.)

2. Get your compost on.

Looking to be sustainable in one swoop? Composting is the way to do it.

40 per cent of the average household bin is made up of organic matter that could be composted.

If you don’t have any space (or don’t want your own backyard compost bin) download the ShareWaste app. It connects you with your neighbours who have a bin or worm farm and are hungry for scraps.

3. Channel a nonna.

Who’s the most sustainable of them all? Chances are your Nan is - from eating leftovers to chopping up old clothes for rags to reusing a yoghurt container as a biscuit tin.

Nonnas are the epitome of using what you have before buying new, so before you throw something away, try and put it to use again.

4. Recycle right.

I’m not going to sugarcoat it, recycling is confusing.

The RecycleMate app has you covered. Simply scan the barcode on an item you’re iffy about and it will tell you which bin it goes in depending on your council area. Genius.

5. Grow your own.

What if I told you that you never had to buy spring onions again? All you have to do is place the white rooty tips in water in a jar on your windowsill and watch them grow.

Snip what you need and they’re the gift that just keeps on giving.

6. Plant trees every time you search.

Switch your default search engine to Ecosia.

They use the advertising revenue from your searches to plant trees. To date, they’ve planted over 130 million - and it doesn’t cost you a thing.

7. Single out bananas.

Bananas are one of the most wasted foods on supermarket shelves.

Did you know that all of the singles that are left behind at the end of the day are often thrown straight in the dumpster?

So rather than grabbing a perfect bunch of five, grab five singles next time you’re at the supermarket #supportthesingleladies.
