Bin Liners

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.

There is no country on Earth that has not been touched from the devastating effects plastics have on our environment. And while many people are resistant to changing simple habits to reduce that impact (such as switching to more eco-friendly bin liners), doing so helps you and the environment both. It’s an easy and helpful choice to make.

Cheaper to Buy and Cheaper to Clean Up

Eco-friendly liners can be cheaper than premium plastic liners, saving you money with every use. They are also made of tough plant-based material making them tear and puncture-resistant, which helps prevent refuse spillage, messy floors, and torn unusable bags. There’s no need to buy custom bins, as they are available in a variety of sizes of bin liners to fit almost every bin size.

Single-use plastic bags might be a little cheaper to produce and, in certain cases, for the consumer to purchase, but at what true cost? Experts estimate that it costs 17-30 cents per bag to dispose of every plastic bag littering streets, roadsides, in garbage bins, landfills, and oceans. With millions more being used every day, it’s not hard to see what the real cost is. In contrast, because of their organic composition, compostable bags require much less to break down.

Bin Liners Can Improved Soil and Less Food Waste in Landfills

The great thing about Certified Compostable bin liners is that they can be degraded in home composting bins for fertiliser. For even more nutrient-rich soil in your yard and garden, you can use plant-based bin bags to start a worm farm. The certification indicates that the bags meet the highest standards for degrading and as they are deemed “worm-safe” they will leave behind no harmful plastic residue when they decompose.

Every year, millions of tonnes of food go to waste, two-thirds of which end up in landfills. Food waste also contaminates otherwise recyclable plastics. Some experts have estimated that food makes up 22% of all refuse in landfills, making them the most prevalent material. Keeping compostable food waste out of landfills and putting them in home composting bins instead can make a huge difference.

Bin Liners That Are Gentler on You and Your Family and Gentler to Produce

You won’t find any toxic dyes, parabens, sulphates, palm oil or petrochemicals in Onya’s environmentally conscious bin bags, only 100% completely organic material. The green liners from Onya are also gentler on the environment because they are 100% GMO-free plant-based and sustainably produced. Plastic single-use bin bags require tonnes of petrol-burning energy and chemicals to produce and recycle, polluting our land, air, and oceans even more.

Make a Difference With Compostable Bin Liners

Not only are green bin liners environmentally friendly, switching to them from plastic single-use bags is an easy and beneficial choice that helps you, too. And because humans across the globe are continually growing landfills and polluting oceans with refuse and unrecyclable plastics, choosing to do nothing is not a viable option. For even more beneficial choices shop online for alternative bin liners and many other eco-friendly and sustainable items for your home.

Make Onya your number 1 choice for green bags and other environmentally friendly products for your pets, home and kitchen such as eco friendly drink bottles and eco sandwich bags.
