Since 1971, 10 states – led by Oregon and Vermont – have passed bottle deposit laws. These so-called “bottle bills” have proven to increase recycling rates and reduce litter on roadsides and in waterways. The laws give people a financial incentive, often five or ten cents per bottle or can, to pick up the litter and return the containers for a cash reward. For example, Michigan passed a 10 cent bottle deposit law in 1976 and today enjoys a 95 percent recycling rate for bottles and cans. That’s almost four times the 25 percent rate in Maryland, which does not have a deposit law. Six times in Maryland over the last decade, legislators have proposed bottle bills. Predictably, soda and beer manufacturers and store chains have fought the laws, because they don’t want to lose any income or take responsibility for handling dirty containers.
