Oregon taxed every bottle a nickel to redeem and litter fell by two thirds

By the late 1960s, throwaway beer and soda containers had replaced refillable bottles across America, and Oregon's highways and beaches were drowning in them: bottles and cans made up roughly 40% of all roadside litter by volume. Hiker and citizen advocate Richard Chambers had grown disgusted by the litter on his walks, and in 1968 he read that British Columbia had adopted a deposit system to cut down on discarded bottles. He brought the idea to his state representative, Paul Hanneman, who introduced a bill in the 1969 legislative session — it was defeated.

Anti-litter campaigns and fines for littering already existed and had failed to make a dent, because the person who dropped a bottle on the roadside never bore any of the cost of picking it up — the incentive to litter and the cost of litter fell on two different people. Passing stricter penalties meant funding more enforcement against millions of anonymous small acts that were nearly impossible to catch.

Charged a 5-cent refundable deposit on every container, making the empty bottle worth carrying home—a cost felt immediately, unlike a fine that almost never arrives.

The deposit makes the cost of littering immediate and personal, unlike a fine that almost never arrives.

No enforcement is needed because the money only moves when the container comes back.

Retailers participate because they want returned containers off the sales floor as much as buyers want their nickel back.

The incentive is baked into the transaction, so it works without monitoring individual behavior.

When a cost falls on a third party, collect a small refundable deposit up front that only returns if the item returns.

Bottles fell from 40% of Oregon's litter in 1971 to 6% by 1979; redemption still topped 80% after the deposit doubled to a dime in 2017. Oregon's was the first bottle bill in the United States; nine more states adopted similar deposit laws in the decades that followed, and the mechanism — make the discarder post a refundable bond against their own litter — became the standard tool for container waste policy still used today, later increased to 10 cents in 2017 to keep pace with redemption behavior.
