2.2 Specifically

Reuse

Reusing a product in the same context or in a different context.

* Reusing is utilizing an object more than one time.
* This takes into account conventional reuse where the object is used again for a similar purpose and new-life reuse where it is used for an innovative purpose.
* An example of reusing is using disposable plastic or glass bottles to drink water over again.

Reuse

**Recycle**

Refers to using the materials from obsolete products to create other products. 

**Repair**

The reconstruction or renewal of any part of an existing structure or device.

**Recondition**

 Rebuilding a product so that it is in an “as new” condition, by repairing it, cleaning it, or replacing parts.

**Re-engineer**

A product that has been significantly redesigned, with improved engineering, from its original form.

**Pollution**

The introduction of contaminants into the natural environment which causes adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat, or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.

**Waste**

Unwanted or unusable materials. Any substance which is discarded after primary use, or it is worthless, defective and of no use.

**Dematerialization**

The reduction of total material and energy throughput of any product and service.

* *Improves product efficiency by saving, reusing or recycling materials,* components *and products.*
* *It impacts on every stage of the product life cycle: in material extraction; eco-design; cleaner production; environmentally conscious consumption patterns; recycling of waste.*
* *It may mean smaller, lighter products and packaging; the replacement of physical products by virtual products (email instead of paper, web pages instead of brochures); home working, and so on*.
* *Reduction of total material and energy throughput of a product or service, and the limitation of its environmental impact through reduction of raw materials at the production stage; energy and material inputs at the user stage; waste at the disposal stage*
* There are potential results of successful dematerialization.

Dematerialization

**Product Recovery Strategies at End of Life/Disposal**

The processes of separating the component parts of a product to recover the parts and materials.

**Circular Economy**

An economy model in which resources remain in use for as long as possible, from which maximum value is extracted while in use, and the products and materials are recovered and regenerated at the end of the product life cycle.
