Plastics In The Green Bin

Food Scraps Recycling

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​

​​Inorganic materials like plastic cannot be composted, but what about plastic items labelled "biodegradable" or "compostable," like bags, produce stickers, cups, utensils, and wipes? These may not be accepted in your green bin program. Read on for more information.

​Plastic items labelled "biodegradable" or "compostable" don't belong in the green bin

Certification standards currently allow a plastic to be called "biodegradable" or "compostable" if it breaks down to a specified degree, over a minimum period of time, when exposed to a certain minimum temperature and other physical conditions. However, not all commercial composting and digestion facilities operate under those conditions.

The result is that many "certified biodegradable" plastics may not sufficiently biodegrade in existing commercial composting or digestion facilities. To be safe, leave them out of your green bin unless your municipality or your service provider specifically says their processing facility accepts them.

​​​​​

Businesses that offer "biodegradable" or "compostable" plastic items may have a program in place to ensure the correct disposal. Private waste haulers may also accept these items.

Most municipal food scraps recycling programs in Metro Vancouver currently do not accept plastic items labelled "biodegradable" or "compostable." Contact your municipality for more information.

What happens if plastics end up in the green bin?

When "biodegradable" or "compostable" plastics go in the green bin, they can cause processing problems and may not break down properly leaving plastic fragments in the finished compost and impacting soil​.

If the facility operator identifies plastic bags or other non-compostable materials in the green bin, the entire load may be rejected and sent to landfill.

What about the large plastic liners in my building’s green bins?

Some buildings use liners in their shared green bins. These are usually removed at the processing facility and put in the garbage. This process is not practical if residents put smaller plastic or plastic-lined bags in the green bins — they are harder to remove and can contaminate the finished compost.

Keep all plastic and plastic-lined bags out of the green bin — even those labelled “biodegradable” or “compostable.”

How can I help prevent contamination?

Keep all “biodegradable” or “compostable” plastics out of the green bin, unless specifically allowed by your municipality or service provider.

If you use a plastic bag to line your kitchen catcher, empty the contents of the bag into the green bin, and then throw the bag in the garbage. You can also line your green bin with a cellulose-lined compostable bag, paper towel, or newsprint instead. These items are accepted in the green bin.

​How to dispose of "biodegradable" or "compostable" plastic items

In most cases, dispose of "biodegradable" or "compostable" plastic items in the garbage. They are not accepted in recycling in BC. Read more on Recycle BC’s website.

Some private waste haulers may accept a specific type of plastic bag. To find out, contact your municipality or your waste hauler.

Do not litter plastic items labelled “biodegradable” or “compostable.” They require very specific processing conditions to break down and will not do so in the natural environment.
