The environmental services sector in Texas is represented here by a mix of large corporations and public entities. Companies like WM and Waste Connections provide comprehensive waste management, recycling, and renewable energy solutions. Safety-Kleen specializes in used oil recycling and parts cleaning, while ALS Life Sciences offers testing, inspection, and certification services.

Alongside these, local government bodies such as the City of Austin, City of Dallas, City of Fort Worth, City of Plano, and City of Corpus Christi are significant employers, managing public services and urban development. A notable pattern is the strong presence of governmental administrations, indicating their substantial role in the environmental and public services landscape of Texas.

How this list is built

Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 12, 2026.
