As Iowa City residents haul the remains of their New Year鈥檚 Eve to curb, they鈥檒l need to remember a new regulation:聽no cardboard in the garbage bin. Starting Jan. 2, a ban on corrugated cardboard at the Iowa City Landfill goes into effect. Corrugated cardboard (the sort of cardboard that has two pieces connected by a wavy layer of cardboard) may be placed in or under curbside recycling bins 鈥� boxes should be broken down, with pieces no larger than 2 ft. by 2 ft. 鈥� or taken to a recycling facility.
鈥淥ur goal in diverting cardboard out of the landfill and into the recycling program is not just waste minimization, but also to reduce the greenhouse gas emissions produced at the landfill,鈥� Iowa City Recycling Coordinator Jane Wilch told聽Little Village. 鈥淗opefully this will help get Iowa City closer to accomplishing our greenhouse gas reduction goal.鈥�
Cardboard buried in a landfill gives off methane, a powerful greenhouse gas, as it decays. According to a 2017 solid waste study, the Iowa City Landfill receives聽4,000 tons聽of cardboard over the course of a year. That鈥檚 a substantial improvement from 2011, when a solid waste study found the landfill was receiving approximately聽15,000 tons each year.
鈥淲e have seen a drastic improvement, which is wonderful, but the bottom line is we still have 4,000 tons of cardboard going into the landfill every year,鈥� Wilch said. 鈥淭hat鈥檚 still 4,000 tons of material we could be putting to better use. Cardboard is a very valuable and reusable material.鈥�
People who put cardboard in their regular garbage bins after Jan. 2 won鈥檛 face a fine, they just won鈥檛 have their garbage collected. Landfill workers will be inspecting the loads garbage haulers bring to the landfill, and loads containing cardboard will be charged double their normal tipping fee. In order to avoid that, haulers won鈥檛 empty a garbage bin if they see it contains cardboard. Instead, they will attach to the bin a notice reminding the resident of the new regulation.
One of the main questions people have had about the ban so far won鈥檛 surprise anyone in Iowa City. 鈥淲e鈥檝e gotten a phenomenal amount of calls and emails about pizza boxes,鈥� Wilch said, with a laugh.
