Reusable Packaging
Any operation by which a package designed to make a minimum number of trips within its lifetime is refilled or reused for the same purpose for which it was conceived, with or without the aid of market‑available products; such packaging becomes packaging waste when it is no longer reused.
(Source: 94/62/EC); in other words, the reuse of packaging in the same form as when it was first placed on the market, for example by refilling. Some examples of reusable packaging include (beer) bottles and pallets.
