Recycling of aluminium requires _________ of energy to make new alumin

1.	Recycling of aluminium requires _________ of energy to make new aluminium.(a) 0.5%(b) 25%(c) 5%(d) 50%I got this question in a national level competition.This intriguing question comes from Chemical Processes of Aluminium in portion Wrought Aluminium Alloys of Aerospace Materials & Processes
Answer» Right option is (c) 5% Best EXPLANATION: Aluminium can be ABSOLUTELY recycled. In any of its forms for example TINS, cans, etc. it can be taken to a plant where it is TREATED. In this process, only five percent of energy is required to manufacture NEW aluminium.
