The environmental services sector in Alabama is diverse, with a notable presence of government administration entities alongside specialized private firms. Many of the larger organizations are municipal or federal bodies. For example, the U.S. Environmental Protection Agency protects human health and the environment, while the City of Huntsville, AL focuses on enhancing citizens' quality of life. Among private companies, Alliance Technical Group provides emissions monitoring and analytical services, and Action Resources specializes in transporting hazardous materials.
The data shows a blend of public and private sector involvement in environmental services. While government entities like Chesterfield County and City of Fresno provide broad municipal services, companies such as TTL, Inc. offer engineering and environmental consulting. EV Battery Solutions by Cox Automotive also contributes by providing EV battery recycling services, indicating a growing focus on renewable energy solutions within the state.

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.
