California Redemption Value, or CRV, is a deposit paid on sales of certain recyclable beverage containers in California.
if you paid $100 in CRV deposits and you returned the bottles, you would get $100 back. That is the essence of the deposit system. The rates for commingled bottles (different materials mixed together) may be modestly lower, but that is just for people who can't be bothered to keep their waste sorted.
