Onya Compostable Bin Liner Description

Varying Compostable Bag Bin Sizes

Due to overwhelming requests from our customers, we are stocking Onya's certified compostable bin liners.

The first preference is composting organic waste using various composting methods to remove the need for bin liners, but 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 misinformation 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 their research, they believe their bin liners meet the highest standards of environmental responsibility available on the market at this time.  Their research is ongoing and as new information comes to light on this subject, they assure that they will offer the most sustainable choice.

What makes 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.

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.  As industrial composting facilities operate hot composts of between 50-60 DegC, their bags break down within around 12 weeks.  These bags will break down over a longer period of time in general waste facilities and 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.

At this stage their bags aren’t certified “home compostable” though 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.


As the 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.

Compostable Bin Liner 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 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.

Very tough, I reuse them

These liners are tough and I just empty the actual contents of the bin out at the end of the week and reuse the same liner. One liner lasts me weeks and I feel better using each one for as long as I can.
