Repair

Repair refers to the fixing of a specified fault in an object that is a waste or a product and/or replacing defective components, in order to make the waste or product a fully functional product to be used for its originally intended purpose. 

Repair extends the product lifetime, for example by replacing broken parts, or removing defects. A user sends its product for repair, to a business intermediary, from the retailer or directly in repair shops. The product comes back to its original user or to a new one, in working order. Repair can therefore also be considered as a service to users.
