Onya Compostable Bin Liners (25pk) are a sustainable, plant based, 100% certified compostable solution for lining your rubbish bin. Available in 4 sizes (8L, 30L, 36L and 60L); see sizing guide info below.
Bin liners have a litre capacity mentioned below, but please note 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 Liner – 5-6 Litre capacity bins
30L Liner – 15-20 Litre capacity bins
36L Liner – 25- 30 Litre capacity bins
60L Liner – 45-55 Litre capacity bins
Bin shapes can vary, but the bags do fit most bin types if matched to bin sizing mentioned above.
While we always recommend 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 Onya's contacts in the industry and our thorough research, they believe that their bin liners meet the highest standards of environmental responsibility available on the market at this time. Their 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 Onya Compostable Bin Liners so good?
Unlike some other bags on the market, Onya 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. Independent university testing shows that after biodegradation Onya bags do not leave any harmful residues.
Their 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.
Their compostable bin liners are certified compostable in industrial composting facilities. Because industrial composting facilities operate hot composts of between 50c-60c, their bags will break down within around 12 weeks. Onya 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 their 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.
(Testing shows that Onya bags are completely compostable as demonstrated by their 100% disintegration after 3 months and > 90% mineralization in less than 6 months. In the laboratory scale composting test according to ISO 14855: their compostable film grade resin reached 90% biodegradation relative to cellulose reference material and meets the biodegradability requirement specified in the EN 13432 standard.
In addition, Onya bags are tested for heavy metals, toxicity to soil, plants and earthworms as per the requirements of the relevant regulatory standards as listed above.)
IMPORTANT NOTES FOR USE: As Onya 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.
