Data center construction waste prompts new landfill policy
Data center construction in Cedar Rapids, Iowa, is rapidly filling the local landfill with waste, including recyclable materials. In response, the Solid Waste Agency has approved a new policy requiring large construction projects to separate clean wood, scrap metal, and cardboard. Loads that still contain mixed recyclable materials can now be turned away to preserve landfill capacity.
Data center construction in Cedar Rapids, Iowa, is contributing to a substantial increase in waste at the local landfill, with over 20,000 additional tons recorded annually, bringing the total to more than 200,000 tons. The Solid Waste Agency investigated this surge and found that data center construction waste, containing recyclable materials like clean wood pallets, scrap metal, and cardboard, was the primary cause. Cardboard, banned from the landfill since 1999, was particularly problematic, as developers were paying double tipping fees but not reducing the amount of mixed waste.
In response, the Solid Waste Agency board approved a new policy requiring large construction projects to separate clean wood, scrap metal, and cardboard. Loads found with these materials mixed in can now be turned away. The policy is being phased in to allow projects time to implement changes, such as on-site grinding, bailing cardboard, and using separate containers for metal. The urgency of this policy is underscored by the landfill's projected lifespan, estimated to be full between 2035 and 2038 at current rates.
