How long does carbord decompose?

Answer 1

Cardboard, unless specifically treated, is relatively biodegradable. Given time, microorganisms and other decomposers will break the fibers of the cardboard down and produce soil. The rate at which this happens depends on a number of factors, including the type of cardboard being discussed, the state of the cardboard at the beginning of the decomposition process, and the nature of the surroundings in which decomposition is expected.
