Green Practices

Green Practices

At Independent Mechanical Industries, Inc. (IMI) environmental responsibility is not a new concept or recent practice. Since 1923, IMI has been a part of society’s development of sustainable practices from treating water and waste water, to filtering the air in heating and cooling systems, to converting boiler fuel systems.

IMI has participated in several “demonstration” projects for the Metropolitan Water Reclamation District of Greater Chicago over its 80 year history. Most notable were the installation of a Zimpro wet oxidation high pressure reactor in the 1950’s and the construction of a state of the art bio-solids processing plant in 2006. Both were projects that the district commissioned in order to “demonstrate” the viability of new technologies in the treatment of waste water and the processing of its by-products.

Today, this tradition continues through IMI’s participation in the next generation of sustainable projects which include the installation of solar arrays, biomass processing facilities and coal gasification plants.
