What makes plywood biodegrade?

Plywood biodegrades primarily due to the presence of organic materials, such as wood fibers and adhesives, which can be broken down by microorganisms like bacteria and fungi. The natural composition of wood allows these organisms to metabolize it over time, especially when moisture and suitable environmental conditions are present. Additionally, the absence of synthetic chemicals in some plywood types can enhance biodegradability, facilitating a faster decomposition process.
