ENCircular economy glossary
Concepts connecting technology, operations and business.
Reference definitions for discussing materials, assets and circular programmes.
- Electronic scrap
Electrical and electronic equipment, components and materials no longer in use. Assessment of condition and composition guides possibilities for reuse, recovery and recycling.
Electronic scrap management- Solid waste management
Organisation of waste flows, from identification and segregation through collection, treatment, final routing and record monitoring.
Solid and industrial waste management- Industrial waste
Waste generated by industrial processes and operations. Composition, origin and condition need assessment to define handling and pathways for value recovery, treatment or disposal.
Industrial waste management- PCR
Recycled material of post-consumer origin, generated after use by the end consumer. Declared origin and proportion need verification in the supply.
PCR resins and applications- ABS
Acrylonitrile butadiene styrene, a thermoplastic used in technical parts. Its qualification depends on formulation and application requirements.
PCR resins and applications- HIPS / PSAI
High-impact polystyrene. The polymer name does not replace a specification of properties, colour and use conditions.
PCR resins and applications- PP
Polypropylene. The composition, additives and variation of recycled material are assessed according to the process and application.
PCR resins and applications- PC/ABS
A blend of polycarbonate and ABS used in technical applications. Composition and performance must be qualified for the product.
PCR resins and applications- WEEE / REEE
Waste electrical and electronic equipment. WEEE is the English acronym; REEE is used in Portuguese. The stream may contain materials and components with different characteristics.
Value recovery- ITAD
Management of the retirement and disposition of information technology assets. It may include inventory, assessment, custody, data handling and routing.
Trade-in and ITAD- Trade-in
A commercial mechanism linking the return of an old asset to the purchase of a new one, through credit or another agreed condition.
Trade-in and ITAD- Closed-loop
An arrangement for returning material to production or to the chain defined by the project, with demonstrated reincorporation.
Industrial closed-loop systems- Reverse logistics
Organisation of product and material returns for recovery or appropriate treatment, according to the flow and applicable requirements.
Reverse logistics- Residual value
The value an asset retains in a given condition and market. Its assessment differs from net proceeds after operating costs.
Value recovery- Chain of custody
Records and responsibilities that allow the possession, movement and transformation of an asset or material to be tracked within the defined scope.
Reverse logistics- Qualification
The process of assessing and approving a material, supplier or application against established requirements and acceptance criteria.
PCR resins and applications- Media sanitisation
A process for treating data on a medium using methods and criteria compatible with the risk and subsequent use. It requires appropriate assessment and validation.
