Clean technology
Products, services or processes that reduce waste and require the minimum amount of non-renewable resources.
New cards
3
Combined Heat and Power (CHP)
A system that simultaneously generates heat and electricity from either the combustion of fuel, or a solar heat collector.
New cards
4
Converging technologies
The synergistic merging of nanotechnology, biotechnology, information and communication technologies and cognitive science.

5
Cradle to Cradle
A design philosophy that aims to eliminate waste from the production, use and disposal of a product. It centres on products which are made to be made again
New cards
6
Cradle to Grave
A design philosophy that considers the environmental effects of a product all of the way from manufacture to disposal.

7
Dematerialization
The reduction of total material and energy throughout of any product and service
New cards
8
Design for the environment software
Software that allows designers to perform Life cycle analysis (LCA) on a product and assess its environmental impact.
New cards
9
Eco-Design
A design strategy that focusses on three broad environmental categories - materials, energy, and pollution/waste.
New cards
10
Embodied Energy
The total energy required to produce a product.
New cards
11
End-of-pipe Technologies
Technology that is used to reduce pollutants and waste at the end of a process.

The method with which energy is transported from a source to where it is used.
New cards
13
Energy storage
The method with which energy is stored for later use.

14
Energy utilization
The method with which energy is used.
New cards
15
Green design
Designing in a way that takes account of the environmental impact of the product throughout its life.
New cards
16
Green legistation
Laws and regulations that are based on conservation and sustainability principles, followed by designers and manufacturers when creating green products.
New cards
17
Incremental solutions
Products which are improved and developed over time leading to new versions and generations.
New cards
18
Individual energy generation
The ability of an individual to use devices to create small amounts of energy to run low-energy products.
New cards
19
Legislation
Laws considered collectively to address a certain topic.
New cards
20
Life cycle analysis (LCA)
The assessment of the effect a product has on the environment through five stages of its life: pre-production; production; distribution (including packaging); utilization; and disposal.
New cards
21
Linear economy
An economy based on the make, use, dispose model.
New cards
22
Local combined heat and power (CHP)
CHP plants that generate heat and power for a local community - the plant is close enough to the community so that the heat generated can be dispersed through the community efficiently.
New cards
23
National and international grid system
An electrical supply distribution network that can be national or international. International grids allow electricity generated in one country to be used in another.
New cards
24
Non-renewable resources
A natural resource that cannot be re-made or re-grown as it does not naturally re-form at a rate that makes its use sustainable, for example, coal, petroleum and natural gas
New cards
25
Product cycle
Also known as the product life cycle, it is a cycle that every product goes through from introduction to withdrawal or discontinuation.
New cards
26
Product recovery strategies
The processes of separating the component parts of a product to recover the parts and materials.
New cards
27
Quantification of carbon emissions
Defining numerically the carbon emissions generated by a particular product
New cards
28
Radical solutions
Where a completely new product is devised by going back to the roots of a problem and thinking about a solution in a different way
New cards
29
Recondition
Rebuilding a product so that it is in an "as new" condition, and is generally used in the context of car engines and tyres.
New cards
30
Recovery of raw materials
Strategies for the separation of components of a product in order to recover raw materials.
New cards
31
Recycle
Recycling refers to using the materials from obsolete products to create other products.
New cards
32
Re-engineer
To redesign components or products to improve their characteristics or performance.
New cards
33
Renewability
The level at which a resource is renewable. The rate that a resource can be replenished.
New cards
34
Renewable resources
A natural resource that can replenished with the passage of time, or does not abate at all.
New cards
35
Repair
The reconstruction or renewal of any part of an existing structure or device.
New cards
36
Reserves
Reserves are natural resources that have been identified in terms of quantity and quality.
New cards
37
Resources
Resources are the stock or supply of materials that are available in a given context.
New cards
38
Re-use
Reuse of a product in the same context or in a different context
New cards
39
System level solutions
Solutions that are implemented to deal with the whole system, rather than just components.
New cards
40
The precautionary principle
The anticipation of potential problems in relation to the environmental impact of the production, use and disposal of a product.
New cards
41
The prevention principle
The avoidance or minimization of producing waste in relation to the production, use and disposal of a product.
New cards
