Biodegradable Bin Liners

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.

With disposable plastic bags littering landfills and oceans by the millions every year, there is a growing effort to encourage people to switch to biodegradable bin liners in their daily routines. But do these bin liners actually work? Are they comparable to their plastic counterparts?

What Are Biodegradable Bin Liners Made Of?

Onya Biodegradable bags are sustainably produced from 100% GMO-free plant-based materials, which means they are completely organic and have no toxic sulphates, dyes, microplastics, petrochemicals, and parabens. And unlike single-use plastic bags, there are no harmful byproducts and massive amounts of petrol-burning energy required to produce and recycle them.

How Do Biodegradable Bin Bags Break Down?

The fastest way of decomposing your biodegradable bin bags is to take them to a nearby industrial composting plant (which you can locate with a quick Internet search.) Here your bags will be heated to temperatures of 50-60 degrees and exposed to the proper microbes for fast and efficient degrading. Compostable bags processed this way will decompose in around 12 weeks, as opposed to the 1000 years it takes for plastics to do the same. Certified Compostable bags can also be used in home composts and worm farms, as they have passed strict standards for decomposing and are deemed to be “worm safe.” This means that when the bags are fully degraded, there won’t be any micro-plastic residue left behind. At 6-12 months, composting your bags takes longer this way than when processed by industrial facilities, but with the help of worm friends, you can speed up this process. And of course they can be sent to landfill to break down to their cellulose beginnings.

How Should You Use Biodegradable Bin Liners?

Onya’s biodegradable bin liners are used just like any other bin liner, and as they tear and puncture resistant they are just as strong!. Wet garbage does tend to expedite the degrading process, so if you find your bags are weakening before you’re ready to take them out, simply wrap any wet refuse in an old newspaper prior to tossing it in the bin to slow the degradation process.

How Do You Store Them?

From the moment they are produced, compostable liners are eager to get back to Mother Earth. It’s for this reason that you should use the bags within 3-6 months of purchase and store them in a cool, dark, and dry location. Otherwise, there is a chance they will start to decompose before you are ready to use them, and you wouldn’t want to waste your bags or your money.
