Overview

Overview
Coal is a sedimentary rock formed from ancient plant matter, but unlike compostable materials, it's undergone intense geological processes that render it inert. This means it won't decompose in a home compost bin, and attempting to do so is futile. It will simply remain as coal within your compost.

Compost Classification
