Environmental product labels can be confusing, especially when similar words are used to describe very different materials.
To help make things clearer, we are breaking down five common myths about biodegradable and compostable products.
Myth 1: Biodegradable and compostable mean exactly the same thing
They are related, but they are not interchangeable.
Biodegradable means that a material can be broken down by microorganisms. The term may not specify the time required, the environmental conditions or what remains after the process.
Compostable products are designed to biodegrade within composting conditions and should return to water, carbon dioxide and organic biomass without leaving harmful residue when composted correctly.
A useful rule to remember is:
Compostable products are biodegradable, but biodegradable products are not necessarily compostable.
Myth 2: Anything labelled compostable can go into a backyard compost bin
Some compostable products require a commercial composting facility.
Commercial facilities operate at higher and more controlled temperatures than most home compost systems. A product marked commercially or industrially compostable may not break down properly in your backyard compost.
Look for information confirming that the item is suitable for home composting before adding it to your home system.
Myth 3: Compostable products can go into the recycling bin
Compostable plastic alternatives are generally not suitable for conventional plastic recycling.
Although they may look similar to ordinary plastic, they are made to behave differently at the end of their useful life. Placing compostable products into a standard recycling bin can contaminate recyclable materials.
Follow the product instructions and your council’s waste guidelines rather than judging the item by appearance.
Myth 4: Compostable bags disappear immediately
Composting is a biological process—not a magic trick.
The speed at which a product breaks down depends on moisture, heat, oxygen, microorganisms and other composting conditions. Even certified home-compostable products need an active and properly maintained compost environment.
A compostable bag stored in a dry cupboard will remain usable because the conditions required for composting are not present.
Myth 5: Choosing compostable products is the only change we need to make
Compostable alternatives can be part of a more responsible approach to everyday products, but they work best alongside other positive habits.
Whenever possible:
- Reduce unnecessary consumption
- Reuse durable items
- Recycle accepted materials
- Separate food and garden organics
- Choose certified alternatives when a disposable product is necessary
- Dispose of every item correctly
Bonnie Bio products are designed for situations where people still need practical, convenient products such as bin liners, dog waste bags and food-service items.
The aim is not to encourage unnecessary consumption. It is to provide better alternatives for commonly used disposable products.
Knowledge makes sustainable choices easier
Consumers should not need a science degree to make a more environmentally responsible purchase.
Start by reading beyond the marketing headline. Look for recognised standards, check the recommended disposal method and choose products from businesses that provide clear information.
Bonnie Bio is helping make the transition easier by offering compostable alternatives that can be used in homes, workplaces, hospitality businesses and commercial environments.
Small decisions may feel insignificant on their own, but millions of better everyday choices can create meaningful change.
