Reduce,Reuse and Recycle

What:I can sequence the life of a recyclable object
So What:First the glass gets collected then it gets sorted into the three different colours(clear brown and green).Then the glass is screened to make sure that there is no contamination.It gets crushed to make it easier to melt.Then the glass gets mixed with sodium bicarbonate and calcium bicarbonate.Then the glass gets heated to 1000'C and then it gets moulded into a new bottle. Finally the glass is sold. Now What:I wonder how they get the machines and how much power they take to run?
