A) It uses less energy to make something from recycled materials than from new materials.
Explanation:
When a recycled material is used to make a new product, it conserves energy because the recycled materials have already been processed once; so making something from it for the second time uses less energy-intensive than the first. For example: Making new aluminium from old products uses 95% less energy than making it from scratch.
