The reduction in use, reuse and recycling of materials by end users…

The idea

End users are the people and organisations who consume products, and their choices drive demand for raw materials. Reducing use means designing and buying less: lighter packaging, longer-lasting goods and products that need fewer materials. Reuse means using an item again for the same or a new purpose, such as refilling a glass bottle or passing on clothing, so no new material is extracted. Recycling means collecting, sorting and reprocessing waste materials into new products, for example melting used aluminium cans to make new ones. All three cut demand for limited resources such as metal ores and crude oil, and they cut the energy needed for extraction and processing, much of which also comes from limited fossil fuels. Less landfill and fewer emissions mean lower environmental impacts.

What earns the marks

• Reducing use lowers demand for limited raw materials such as metal ores, crude oil and clay.
• Reuse extends an item's useful life, so fewer new products are manufactured and less material is extracted.
• Recycling reprocesses waste materials into new products, reducing the need to extract and process virgin raw materials.
• Lower demand for raw materials reduces the energy consumed in extraction, transport and processing, and much of that energy comes from limited fossil fuels.
• Reducing, reusing and recycling cut the volume of waste sent to landfill and reduce pollution and habitat damage.
• A named example, such as refilling a glass bottle or recycling aluminium cans, can illustrate how each approach reduces resource use and environmental impact.

Common mistakes and how to put them right

• Treating reduce, reuse and recycling as identical.

  Put it right: Reduce means using less in the first place, reuse means using an item again, and recycling means reprocessing the material.

• Assuming recycling always removes the need for raw materials.

  Put it right: Recycling reduces but does not eliminate demand, because some products cannot be recycled indefinitely.

• Ignoring the energy saved.

  Put it right: Reprocessing recycled material usually uses less energy than extracting and processing raw material, so recycling also reduces demand for limited energy sources.

Exam tips

• Link each of the three approaches to a specific resource or impact, such as aluminium cans and bauxite ore, rather than writing generally about helping the planet.
• Use the phrase limited resources when explaining why reduction matters, because the specification ties these actions to resource depletion.
• When a question asks for a benefit, state the action, the resource or energy saved, and the resulting environmental effect in one clear chain.
