Reuse is the action or practice of using an item, whether for its original purpose (conventional reuse) or to fulfill a different function (creative reuse or repurposing). It should be distinguished from recycling, which is the breaking down of used items to make raw materials for the manufacture of new products. Reuse – by taking, but not reprocessing, previously used items – helps save time, money, energy and resources. In broader economic terms, it can make quality products available to people and organizations with limited means, while generating jobs and business activity that contribute to the economy.
Reuse centers (also known as a "swap shop" or a "take-it-or-leave-it") facilitate the transaction and redistribution of unwanted, yet perfectly usable, materials and equipment from one entity to another. The entities that benefit from either side of this service (as donors, sellers, recipients, or buyers) can be businesses, nonprofits, schools, community groups, and individuals. Some maintain a physical space (a reuse center), and others act as a matching service (a virtual exchange). Reuse centers generally maintain both warehouses and trucks. They take possession of the donated materials and make them available for redistribution or sale.
Virtual exchanges do not have physical space or trucks, but instead allow users to post listings of materials available and wanted (for free or at low cost) on an online materials exchange website. Staff will help facilitate the exchange of these materials without ever taking possession of the materials.
One way to address this is to increase product longevity; either by extending a product's first life or addressing issues of repair, reuse and recycling. Reusing products, and therefore extending the use of that item beyond the point where it is discarded by its first user is preferable to recycling or disposal, as this is the least energy intensive solution, although it is often overlooked.
