Varying Compostable Bag Bin SizesDue to overwhelming requests from our customers, we are pleased to be able to offer you our full range of certified compostable bin liners.

While our first preference is composting your wet waste if possible cutting out the need for bin liners at all, we understand that each household is different and opting for no bin liner may not work for you.

When it comes to disposable bin liners, there can be a lot of mis-information out there and as this sector is rapidly developing, it can be hard to know what to look for in a bin liner.

Through our contacts in the industry and our thorough research, we believe that our bin liners meet the highest standards of environmental responsibility available on the market at this time. Our research of course is ongoing and as new information comes to light on this subject, you can be assured that we will always aim to offer our customers the most sustainable choice we can.

What makes our Compostable Bin Liners so good?

Unlike some other bags on the market, our bags are CERTIFIED compostable to Australian, European, USA & Japanese standards, which means they have been independently assessed to break down to virtually undetectable levels in the soil and are deemed “worm safe” with no micro plastic residues left behind.

Our compostable bin liners are available in 4 sizes (8L, 30L, 36L and 60L) and are made from 100% GMO free renewable plants and are free from any plastic additives such as Polypropylene, Polyethylene, Polystyrene & PVC.

Our compostable bin liners are certified compostable in industrial composting facilities. As industrial composting facilities operate hot composts of between 50c-60c, our bags will break down within around 12 weeks. Our bags will of course break down over a longer period of time in general waste facilities, however due to the lack of necessary microbes found in these facilities it can take 6-12 months or more for the bags to break down to their natural cellulose beginnings.

Although at this stage our bags aren’t certified “home compostable” they can still be used in this environment, but like a general waste facility will simply take longer to break down if not hot composted.

IMPORTANT NOTES FOR USE: As our liners are compostable, unlike traditional single use plastic bin liners, it is important they are used ideally within 3-6 months of purchase and kept in a cool dark space, otherwise they may start to break down.

Compostable bin liners need to be treated slightly differently to traditional plastic bin liners as the material they are made from is designed to break down easier than plastic – which is a good thing, however, this may mean that if placing wet waste in your bin liners you need to empty your bin more frequently as if moisture is added, the composting process may begin and could lead to spills or splitting when emptying your bin on a weekly basis.

If possible, wrapping your wet waste in old newspaper first may help increase the life of your bag by preventing moisture from building up.

Sizing Guide:

Although bin liners have a litre capacity mentioned, this does not necessarily match the exact litre size of your bin. Due to the gusseted bottom in the bag, the bags lose a little height when in the bin, so we recommend the following:

8L/2.1 Gallon Liner – 5-6 Litre/1.5 Gallon capacity bins

30L/7.9 Gallon Liner – 15-20 Litre/4-5 Gallon capacity bins

36L/9.5 Gallon Liner – 25- 30 Litre/6-7 Gallon capacity bins

60L/15.8 Gallon Liner – 45-55 Litre/11-14 Gallon capacity bins

Bin shapes can vary, but the bags do fit most bin types if matched to bin sizing mentioned above.


Eco Friendly Compostable Waste Garbage Bin Bags Liners

It can be challenging to find a functional yet eco-friendly way to dispose of your home waste without using plastic bags, but by putting in the extra effort to find alternatives, you can rest assured knowing that you are helping to reduce plastic pollution. Here are the best ways to dispose of home waste the eco-friendly way without the use of plastic bin liners;

Minimise Plastic Waste With Our Eco Friendly Bin Liner Bags

Invest in reusable shopping bags – Everyone has a need for shopping bags to help you carry groceries from the markets to your home. Brown paper bags which can be reused and recycled seem like an eco-friendly solution, but they’re not that practical for carrying heavy groceries home. On the other hand, reusable shopping bags are a lot stronger than brown paper or single use plastic bags and can be used for numerous functions. Invest in a collection of reusable shopping bags (Onya has a few options made from rPET, material made from recycled drink bottles) and keep them in your car and home so you won’t have to buy groceries in single use plastic bags ever again.

Use our eco-friendly bin liners – Stop buying plastic bin liners and invest in our plant-based compostable bin liners instead. With just a little bit of adjustment to your normal routine, these environment-friendly bags become just as functional as normal plastic bags, and you can easily dispose of all of your non-compostable and non-recyclable rubbish in them.

Start composting – A compost bin is a handy device where you can toss all of your green waste. With a compost bin, you will also have a steady supply of natural compost to use in your garden.

Start worm farming – Worm farming is another good way to dispose of your green waste. Get a batch of earthworms and start tossing all of your household waste into your bin. You can even toss your Onya compostable bin liners into your worm farm. These bags are worm food safe, and those critters will help decompose the bags a lot quicker.

Our Bin Liners Are Suitable For Your Every Need

We have a range of compostable bin liners available from 8l up to 60l. With these bags, you can fulfil your rubbish removal need in an eco-friendly way. Our smaller bags are perfect for small bins in bedrooms or bathrooms while the 30l, 36l and 60l are perfect for your larger bins. You can easily replace your every need for plastic trash bags with our certified compostable bags.

    I’m really thrilled I discovered Onya compostable bags. I’m using fewer bags and I’m so happy with their quality, I’ve purchased for others as gifts.
