When we recycle, used materials are converted into new products, reducing the need to consume natural resources.

If used materials are not recycled, new products are made by extracting fresh, raw materials from the earth, through mining and forestry. Recycling helps conserve important raw materials and protects natural habitats for the future.

Recycling Saves Energy

Using recycled materials in the manufacturing process uses considerably less energy than that required for producing new products from raw materials – even when comparing all associated costs,including transport, etc.

Reading Task

1.Read the article. In pairs, discuss the most interesting idea from the text.

Recycling Saves Resources

There are also extra energy savings because more energy is required to extract, refine,transport and process raw materials ready for industry, compared with providing industryready materials.

Recycling Helps Protect the Environment

Recycling reduces the need for extracting (mining, quarrying and logging), refining and processing raw materials. All of these create substantial air and water pollution.

As recycling saves energy it also reduces greenhouse gas emissions, which helps to tackle climate change.
