The Mark-Costello Co. was established in the Greater Los Angeles area in 1956 as a Sales Agency/Distributor, with emphasis on designing, supplying and servicing engineered systems in two diverse fields; Centralized Lubrication Systems and Mechanical Power Transmissions. As the company grew, these products became the foundation of our Industrial Division. We continue to be major supplier of Industrial Centralized Lubrication Systems. In 1971, we formed our Waste Systems Division. The main thrust of this division (which has experienced phenomenal growth the past 30 years) is providing systems for handling solid and medical waste. Today, The Mark-Costello Co. is a large supplier of the compactors, balers, medical waste processing equipment; i.e., waste sterilizers and related waste handling, and recycling systems, in the United States and other parts of the world.
