Abstract
Systems and methods for increasing the value of trash. By increasing the value of trash, persons have an incentive to collect litter and deposit the collected litter at an appropriate trash collection site (e.g., garbage can, reverse vending machine, recycling center, etc.). In one aspect, a financial instrument (e.g., a Bitcoin, Bitcoin-like value, account identifier, or any other financial instrument) or a pointer to a financial instrument is attached to the object itself or placed inside of the object in a way that is not easily extracted before appropriate time.
