We (the beverage industry/my company) are only in practice responsible for deposits. While we are required to take collections, no consumers really returns them to us. The return burden often falls on the retailers, who collect deposit directly from consumers.

When we sell product to a retail store. We collect a 10¢ deposit per can from them. The retailer then collects a 10¢ deposit from the customer.

My company gives all our collected deposits to a co-op (which is state run I believe) who handle the collection/recycling of the containers.

I interact with our bottle bill on a pretty small scale, but I believe that only changes my reporting frequency.
