Saturday’s Hazardous Waste Collection Day drew 950 carloads of people and their disposable hazardous materials, from all 25 local communities involved in the project. Approximately 1,000 residents of the 25 participating communities preregistered for permits, which cost those who did not register in advance $10, Jerry Hughes, Bangor Public Works training officer, said Tuesday. Workers collected 808 television and computer monitors, 205 pounds of batteries, 1,584 fluorescent lamps, 3,371 gallons of waste antifreeze and 1,140 gallons of waste oil. “I think [these events] are really good because then we know this stuff isn’t getting hidden in the trash and put in the landfills and incinerators,” Wendy Warren, environmental coordinator for Bangor, said Tuesday.
