What can be composted depends on the rate at which it breaks down, the type of material and also whether our particular compost process can efficiently turn it into compost. 

For example, the ability to compost plastic bags labelled as biodegradable or compostable varies between different brands meaning each type or brand of bag breaks down at a different rate. So, even though a bag is labelled as biodegradable, it doesn’t necessarily mean it will break down fast enough for the composting process that we use. Since they don’t break down, plastic bags produce litter during the composting screening process, which is a nuisance and can be costly to clean up.
