No, perlite is not biodegradable. It is a naturally occurring volcanic glass that is processed by heating to expand, creating a lightweight and porous material. Because it does not decompose or break down over time, perlite remains in the environment indefinitely. However, it is chemically inert and does not release harmful substances, making it a stable choice for gardening and horticulture.
