Leadership and Stability

In 1949, Robert C. Ross founded one of the first hazardous waste management companies in the nation. He began Robert Ross Industrial Disposal because he saw an opportunity to meet the hazardous waste management needs of companies in northern Ohio. In 1958, this industry pioneer built one of the first hazardous waste incinerators in the country.

Today, Robert Ross' entrepreneurial spirit and desire to meet the needs of customers lives on. Ross Environmental Services, Inc. and its related companies, Ross Incineration Services, Inc. and Ross Transportation Services, Inc., work to solve environmental problems for their customers. The companies provide a wide range of reliable environmental management services to industry.

Our longevity has been built upon a stable base that includes committed ownership, a strong balance sheet and innovative, experienced associates. Today, Ross Environmental and its related companies continue to be closely and privately owned by shareholders directly descended from its founder. In an industry where ownership and stability are issues of concern for many companies, the Ross companies have remained a solid and reliable provider of environmental services.

Ross Environmental Services is based in its Business Center at the Great Lakes Technology Park across from the campus of Lorain County Community College in Elyria, Ohio. Its related companies, Ross Incineration Services and Ross Transportation Services are located in Eaton Township, Ohio in a rural area approximately 30 miles southwest of Cleveland.

Combined, the companies have approximately 230 associates who have hundreds of years of experience in the environmental services industry.
