deposit systems have a limited lifetime, the get killed by inflation. For example, glass beer bottles in GER have a deposit of 8 cent. This used to be 15 Pfennig, a pretty high amount when the deposit was introduced. But since you can't raise the deposit (bottles suddenly would raise in value) and inflation pushes down the purchasing power, even bottle collectors tend to leave glass bottles behind.
