Compostable post bags

Here at Two Blue Birdies, we’re phasing out our use of plastic courier bags. This means that the vast majority of our orders are sent using cardboard boxes, paper filled Jiffy bags and comPOST bags. Until we exhaust all of our old stock, you may find that your order arrives in one of our older plastic courier bags. If you’d prefer for your order to be packaged in compostable material, just drop us a quick email.

 

So what are comPOST bags? Glad you asked, cos we think they’re pretty nifty! They’re made from corn starch with a binding agent for added flexibility. And the best bit – they can be composted at home!

When your Two Blue Birdies order arrives, you can either keep the bag or box for re-use, or pop it in your compost bin or worm farm along with your food scraps and garden waste.

Why are comPOST bags black?

It's a bit of a balancing act - If the bags were white, they would be slightly see-through. If they’re black they aren’t. If the bags were thicker, they would take longer to break down and wouldn’t be certified as Home Compostable.

 

What are comPOST bags made of?

Corn starch (made from corn not fit for consumption)

PLA (Polylactide, which is made from waste corn & other plants)

PBAT (Polybutyrate Adipate Terephthalate). You can read more about PBAT here: https://betterpackaging.co/what-is-pbat/

 

How long will comPOST bags take to degrade?

That depends on the conditions they’re in. In a ‘standard’ home compost, they have ben certified (AS5810-2010) to biodegrade within 180 days. Under commercial composting conditions, it happens much faster. As litter or in landfill it would happen slower, but it will happen. The Australian Standard is one of the most rigorous in the wold and includes a worm toxicity test which means that comPOST packs are safe to be eaten by worms.
