Recycling Reducing resource use by collecting

usable waste materials and using them to produce new items

Many materials can’t be recycled Can’t recycle completely

Benefits of Recycling Reduce waste Source of limited resources (steel,

aluminum) Prevents environmental damage

from using new resources

Drawbacks of Recycling Often more expensive than new

resources Consumer demand Often more energy intensive than

new resources

Recycling Paper One of easiest to recycle Less energy and less water than new

paper from trees Weakens each time it’s recycled

Recycling Aluminum Natural- bauxite ore Large amounts of energy/water to

produce aluminum Recycling reduces air pollution, water

pollution, and energy by as much as 95%

Recycling Other Minerals Glass Iron Steel Silver Copper Lead Zinc Motor Oil

1L of motor oil can contaminate 1,000,000L of water

Uses 2/3 less energy to recycle motor oil than to refine it

Recycling Plastics Made from petroleum Difficult to recycle Recycled by code Recycled plastic is weaker Dyes, filler, additives (separate)
