OLYMPIA — April was Earth Month, and the Washington Department of Ecology marked the occasion with an emphasis on keeping Washington litter free. Roadside litter affects road safety, the environment and the wellbeing of local communities. More than 75% of Washington residents do not litter, but despite this, an estimated 26 million pounds of material still litter Washington’s roads every year.

Results from Ecology’s 2022 statewide litter study show there are 73,580 separate pieces of litter — or 1,579 pounds of trash — per mile per year on Washington’s interstate highways. Even on local roads, you can find 18,051 pieces of litter — 143 pounds — per mile per year. Common materials include plastic film packaging, food wrappers, cigarette butts, and beverage containers, all of which are not biodegradable and can leach chemicals into the environment.
