Recycled Metal

How could I make an essay on "Scrap Metal Recycling" argumentative?

I have to write an argumentative essay on an environmental issue, which I chose "scrap metal recycling" because it's interesting and different, I just don't know what I could argue about it, or what people could disagree about it?
Thanks for your help!

you could argue that the cost of transport is more than the "value" of the metal.

But what is the "value" of recycling?

How does one quantify the environmental benefit of NOT having toxins leach into water tables and soil from metal that is landfilled?

Recycling creates more low-skilled jobs that landfilling certainly.

and careful post collection separation increases the value of the metals.

some like aluminum also have a hidden savings, as most aluminum can be recycled right back into other alum products, and there is the savings of the high electrical energy costs to refine new aluminum from the mined ore.
