How long does it take for canvas to decompose?

Canvas, typically made from cotton or linen, can take several months to a few years to decompose, depending on environmental conditions such as moisture, temperature, and exposure to sunlight. In ideal composting conditions, it may break down more quickly, while in drier or less favorable environments, the process can take much longer. Synthetic canvas, like that made from polyester, can take significantly longer to decompose, often hundreds of years, due to its non-biodegradable nature.
