Analysis
NAICS 5622 is the 2022 industry group for waste treatment and disposal, part of 562 (Waste Management and Remediation Services).
It has only one more detailed code, 56221, which covers exactly the same activities; the definition, index entries and statistics are on that page.
Between 2018 and 2023 the number of establishments grew 26% and employment rose 7%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.
County Business Patterns counts 3,326 US establishments in this code in 2023, employing 62,599 people at an average annual payroll of $81,260 per employee (70th percentile of national industries). 42% of the establishments have fewer than five employees, which is close to the national mix.
By establishments it ranks 3rd of the 3 codes at this level within Waste Management and Remediation Services, with 11.4% of them.
