How to Check Whether Compostable Bags Break Down at Home
A bag marked compostable may not break down well in a backyard compost pile.
Different bags are made from different materials.
Some need very hot conditions to break down.
Those conditions may be available in commercial composting facilities, but not at home.
The article advises checking whether a bag is certified for home composting.
It mentions an experiment suggested by Maninder Singh Nayyar, but the excerpt does not explain how to do it.
So, based on this article, there are no experiment steps to follow.
The article says “compostable” does not necessarily mean a bag will break down quickly in a home compost pile.
Whether a bag decomposes depends in part on its material and certification.
