Recycling aluminium 0 Overview Using this Resource Connecting to the Curriculum Marking Student Responses Further Resources This task is about the energy used to make aluminium cans. Fact file Cans that are made now are 25% thinner than 30 years ago. Most of the energy for making the world's aluminium comes from dams. Only 5% of the energy that is used in making a new can is needed to make a recycled can. Question 1Change answer a) Give one reason why recycling of aluminium cans is good for our environment. a) Give one reason why recycling of aluminium cans is good for our environment.
