Explanation:
- Step 1: New and old materials
Sustainably-grown timber is used to make the paper that makes up the newspapers you see in news agencies around Australia.
Plantation pine has its fibres separated in a process called refining, where two plates of metal crush the wood and release the fibres. The wood comes principally from forest thinnings, and leftovers from harvesting plantations grown for housing and furniture.
In addition to fresh timber, recovered fibres are separateduring pulp production by simply stirring the old newspapers together with old magazines in a mixing tank called a pulper.The reuse of these materials allow for waste to be diverted from landfill and reduce the amount of new timber that needs to be used. In addition, pulp production based on recovered paper consumes less energy than production from raw materials because the fibres in recovered paper are more easily separated than those within wood.
The wood fibres that make up newspapers and magazines can recycled back into paper up to six times, significa
ntly reducing the amount of energy and materials used.
