Chemical reactions with a high percentage yield can have a low atom economy if a large quantity of unwanted by-products are produced and not recycled back into the reaction. Does that make sense?

You surely know how reactive barium would be with acid. I say "would be" as I like my eyebrows, so wouldn't want to mix them.

Ba + 2HCl -> BaCl2 + H2.

Yield will be 100%, but atom economy - if you're trying to make H2 and the BaCl2 is a waste product.
