Degradability refers to the ability of a substance to break down into smaller, simpler components over time, usually in the presence of natural processes. Synonyms for degradability include biodegradability, disintegration, decomposition, breakdown, dissolution, and decay. Biodegradability is often used in reference to organic matter, such as food waste and paper products, that can be broken down by microorganisms into carbon dioxide and water. Disintegration and decomposition both refer to the breakdown of materials into smaller particles or fragments. Breakdown and dissolution can describe either physical or chemical changes that result in the loss of identity or structure of a material. Decay specifically refers to the breakdown of organic matter into simpler substances that can nourish other organisms.
