Starting July 1, residents who dispose of their trash at the transfer station will have to place it in designated town trash bags, available at local stores. The cost will be $2 for a 30-gallon bag and $1.25 for a 15-gallon bag. Currently, there is no cost to residents to dispose of trash at the station, located on Route 27. The town last week signed a contract with North Carolina-based WasteZero to supply the trash bags. Town Administrator Ron San Angelo said that the switch to the “pay as you throw” system will encourage recycling, reducing the town’s trash disposal costs. Currently, Hanson pays $35.50 for every ton of trash it brings to the Covanta SEMASS waste-to-energy plant in Rochester, a price that is expected to rise to $55 to $60 next year. Also helping ease the town’s trash costs will be the new revenues it will receive from keeping most of the proceeds of the bag sales.
