Incinerator Facilities.    We own and operate five incinerator facility locations that have a total of ten incinerators, including our new incinerator at Kimball, Nebraska which opened in late 2024. The nine incinerators that were operational during the full year had an overall average utilization of 87.6% on an annual practical capacity of 561,721 tons. Our practical capacity is not based on a theoretical 24-hour, seven-day operation, but rather is determined as the production level at which our incinerators can operate with an acceptable degree of efficiency, taking into consideration factors such as longer term customer demand, permanent staffing levels, operating shifts, holidays, scheduled maintenance and mix of the waste processed. Capacity utilization is calculated by dividing actual production tons by practical capacity at each incinerator. The following table summarizes the practical capacity and utilization for each incinerator for the year ended December 31, 2024:# of IncineratorsPractical Capacity (Tons)Utilization Rate Year Ended December 31, 2024Arkansas(1)3160,07295.9%Nebraska(2)258,80886.2%Utah166,81597.3%Texas3165,50077.6%Ontario, Canada(1)1110,52685.6%10561,72187.6%
