The Hawaii Department of Health, in its 2008 annual report to the state legislature, noted a general decline in beverage container litter since the enactment of the bottle bill. It also recommended that the deposit on beverage containers stay in effect, to "decrease the temptation to litter and increase the incentive to recycle." The tables below are copied from the DOH report and consist of data from the Ocean Conservancy's International Coastal Cleanup events.
