Circular Economy
Product Lifetime
How long a product remains functional and in use — a core circular economy variable shaped by design, repairability and business models.
Definition
Product lifetime is the duration for which a product remains functional and in use, determined by technical durability, repairability, upgradability, emotional attachment and economic incentives. Extending lifetimes is a primary circular economy strategy: slowing resource loops reduces material demand, waste and the embodied impacts of replacement production.
