How long does construction paper take to decompose?

Construction paper typically takes several weeks to a few months to decompose, depending on environmental conditions such as moisture, temperature, and exposure to sunlight. If it is not coated with plastic or other treatments, it will break down more quickly in composting conditions. However, the presence of dyes and additives in some construction papers can potentially slow the decomposition process. Overall, it's more biodegradable than many synthetic materials but still requires proper conditions to decompose effectively.
