What are your products made of?

Most Bonnie Bio products are made from PLA (polylactic acid). Bonnie Bio’s products are predominantly made from corn starch derived PLA, which is biodegradable, carbon-neutral, and edible. Biodegradable plastics take three to six months to fully decompose (rather than the several hundred years it takes for plastics to decompose. The rate of decomposition will depend on a range of factors including temperature, moisture, and oxygen levels.

What is the shelf life in store?

Bonnie Bio’s products are as robust and durable as plastic – so much so that it’s hard to tell them apart when it comes to functionality. In-store, our products have a shelf life of 12-18 months and this shelf life is extended when products are kept in a cool, dry environment.

How quickly will your products decompose?

The speed of degradation of our products relies on environmental conditions. Oxygen is a critical consideration – and compostability is dormant in anaerobic or low-oxygen environments. High temperatures and UV exposure also tend to accelerate the rate of decomposition. In an open or turned landfill, our products decompose in around 40-90 days. Store our products in a cool dry place to maximise their shelf life (12-18 months).

How should I dispose of your products?

Our products will decompose in an open or turned landfill – or in home and industrial composting facilities. Please consult with your local council on the way to achieve maximum compostability – and be aware that the contents placed inside your waste bag may not be biodegradable or compostable. Our exterior packaging is printed with eco-solve ink. Please be mindful of using the correct recycling bin on disposal.

What is an 'open' or 'turned' landfill?

Anaerobic landfills exist to reduce methane production. This limited oxygen environment is not ideal for composting, however – and this is where the kind of landfill becomes important. An open or turned landfill exposes its contents to moisture, UV light, and oxygen, which means the rate of decomposition is faster. If you are disposing of Bonnie Bio products, please consult with your local council to find out whether it is advisable to dispose of our compostable products in your green waste bin.

Are your products home compostable?

Yes. Under the right conditions, our corn starch products will decompose in 40-90 days in your home compost heap – alongside your kitchen cuttings and garden waste. Home composting has myriad benefits, including the potential for reduced waste management fees. Please keep in mind that, while our multi-purpose bags are compostable, some of the waste you may choose to use them for may not be.

Why should I use your products over paper and recyclable alternatives?

Composting is the gold standard over recyclable and degradable options when it comes to going green. The manufacturing process of our compostable products is more environmentally friendly with reduced energy usage and emissions over paper alternatives. It is also more durable and less bulky for the purposes of transport, all of which have a knock-on effect in terms of its overall impact on the environment.

Are your products certified?

Absolutely. Our bags have been manufactured to comply with the following composting & biodegradable standards: EN 13432 | AS 5810 | ASTM D6400 ASTM D6868.

Our straws have been manufactured to comply with the following composting & biodegradable standards: EN 13432 | AS 5810 | ASTM D6400 ASTM D6868.

PLA is an all-natural material that’s both compostable and biodegradable. That means the goodness of the earth goes into making this durable, reliable plastic alternative. What’s more, PLA returns goodness to the earth when it decomposes – releasing water, biomass, and carbon dioxide during this process (without the toxins of traditional plastics and other plastic alternatives). PLA takes six to nine months to break down depending on temperature, moisture, and oxygen.
