My question is for Mr. Nickel.
Part of the problem around measuring the value of recycled waste materials, is that it's important to consider more than just the value. My colleague gave glass as an example. If you measure the value of a cracked glass that ends up in a garbage bin, it certainly isn't much. But if you measure its actual value, you realize that the materials used to make that glass, through silica and phosphate extraction, could represent hundreds of kilograms of raw materials that were processed and crushed up.
Shouldn't we start to think about that? Consider a 200-kilogram bulldozer battery that gets thrown out. How much does the lead ore that was processed to manufacture the battery weigh? That's something we should think about.
What is your take on that?
