In general, it is not recommended to put flour in a home composting bin.
Flour is made up of refined grains, which do not break down easily in a composting environment.
Additionally, flour can attract pests and animals to your compost bin, which can create an unwanted mess.
It is best to avoid adding flour to your home composting bin.
When flour is added to a composting bin, the microorganisms that break down organic matter in the compost are unable to digest it effectively.
This is because flour is made up of refined grains, which have had their outer layers removed.
These outer layers contain the majority of the nutrients and fiber that the microorganisms need to break down the grains.
Without these nutrients, the microorganisms are unable to break down the flour and it remains largely unchanged in the compost.
