What are your caps worth?

Tell me how many caps you collect each week. I do the maths with the real rates Resialentejo and Amorim pay.

You, in a year
With 100 neighbours doing the same
The whole village (1,000 families)

Approximate maths: a plastic cap or a metal cap weighs about 2 g and a stopper about 4 g. Plastic at €411.60/t, metal caps at €465.60/t, cork at €500/t. A month of treatment costs €9,075.
