How to use Illinois EPA's Landfill Capacity Report
Illinois Landfill Disposal Capacity Report is Illinois EPA’s annual report regarding the expected disposal capacity available for municipal waste at active Illinois landfills. (Active landfills are those that accepted waste during the reporting period.) The report includes data on each of Illinois EPA’s administrative regions. Region 1 includes Northwestern Illinois counties; Region 2 includes Chicago Metropolitan counties; Region 3 includes Peoria/Quad Cities area counties; Region 4 includes East/Central Illinois counties; Region 5 includes West/Central Illinois counties; Region 6 includes Metropolitan East St. Louis counties; and Region 7 includes Southern Illinois counties.
Each regional section includes a summary for each landfill. Provided are: A map with locations of each landfill in the region, the landfill name, the volume of solid waste accepted by the landfill during the calendar year, the remaining disposal capacity of the landfill as of January 1, 2026, and life expectancy. In all, this report includes details of 37 landfills.
Permitted landfills report capacity in terms of historic permitting data and the remaining capacity based on the volume of waste currently in place at the facility. Previous reports used historic permitting data when determining landfill life expectancy. However, this report uses the in-place capacity, which is the landfill capacity after accepted waste has compacted. This figure is a more accurate reflection of existing conditions at each facility.
These figures are submitted to the Agency in “gate cubic yards,” or the volume of waste entering the landfill’s gate. Remaining capacities are expressed as certified gate cubic yards, meaning that calculations have been certified as true and accurate by a licensed professional engineer. These figures are found on landfill specification pages in each of seven regional sections in this report. Gate cubic yards can be difficult to visualize. To better understand the measurement, divide gate cubic yards by the industry standard of 3.3 to achieve approximate tons. In other words, 3.3 gate cubic yards = one gate ton.
During calendar year 2025, 37 permitted landfills in Illinois reported receiving a total of 48,503,183 cubic yards of waste.
As of Jan. 1, 2026, 37 active landfills had a combined remaining capacity of 968,522,230 cubic yards.
At the average in-place disposal rate over the past five years, these landfills will have a cumulative life expectancy of approximately 20 years. However, cumulative landfill capacity and life expectancy may vary year-to-year based on a number of factors, including waste disposal rates, landfill expansion, and the construction of new landfills.
