About Us


Vapor Recovery Specialty Company (VAREC) began business in the 1930’s at its manufacturing plant in Compton, California. During the infancy stages of a growing biogas market in the early 1950’s, Varec decided to focus on delivering quality biogas handling products, specifically designed with each customer in mind. And thus, Varec Biogas was born.

Varec Biogas initially sold directly to end-users, limiting its market reach. A Sales Representative Network established in the 1970’s, met the growing demand which catered to Municipal Wastewater Treatment Plants. A select number of Sales Representatives in the U.S. helped Varec Biogas become the leading experts in biogas handling and safety products and provide service to Wastewater Treatment Plants that utilize anaerobic digesters for biosolids treatment.

On April 15, 2019, Ovivo Inc. acquired Westech Industrial Inc., (dba) Varec Biogas a wholly-owned subsidiary of Westech Industrial Ltd. Varec Biogas’ product line is complementary to Ovivo’s biosolids management and resource recovery offering and will remain dedicated in providing total solutions to the biogas market.
