Fewer waste rock heaps
Reduced burning of fossil fuels
Conserves finite resources
Test yourself on Reducing Use of Metal
When compared with mining and extracting, recycling metals...
What are the steps in the process of recycling metals?
What is one benefit of recycling metal compared with mining and extracting new metal ore?
Recycling metal requires less energy than mining and extracting new metal ore. Why does this also reduce the burning of fossil fuels?
A factory that currently recycles scrap metal switches to mining and extracting new metal ore instead. What would you expect to happen to the number of waste rock heaps it produces?
