The Board of Selectmen at 7:35 p.m. Tuesday is scheduled to hold a public hearing on the future of trash and recycling collection in Stoneham. Officials have expressed concern about the town’s trash disposal costs and are considering various options to increase townwide recycling. Among the ideas being considered: limiting the amount of trash residents can throw away each week and increasing the frequency of recyclable material collections. Currently, recyclables are collected on alternating weeks; the town is considering having recyclables picked up each week with the regular garbage collection. The town currently offers single-stream recycling so that residents can mix paper with plastics, tin and aluminum cans, and glass bottles. The public hearing is scheduled to take place in the Town Hall banquet room, 35 Central St.
