Monroe Environmental has been supplying environmental control systems for manufacturers of industrial, commercial, and residential building products for over four decades. We have installations controlling air emissions and treating wastewater streams at many of the largest production plants in operation. Monroe’s application specific approach can help solve the most challenging environmental problems for nearly every type of manufacturing process.
The National Emission Standards for Hazardous Air Pollutants (NESHAP) regulations apply to many sources of air pollution that are common to manufacturing of building materials including acid gasses, alcohols, metals, fine aerosols, particulate matter, and VOCs. Dryers, ovens, furnaces, boilers, and kilns used for production of bricks, tiles, and roofing products can emit many pollutants simultaneously, often requiring multi-stage emission control. Batch mixing, cutting, buffing, polishing, and finishing processes often produce particulate matter, aerosols, and fine dust requiring efficient capture and filtration to reduce and eliminate health risks to plant workers and the surrounding community.
Water treatment involves liquid streams from waste, rinse, and process waters often containing large quantities of oils, TSS, metals, and floating materials. Each of these constituents requires targeted treatment which can vary depending on production and application specific requirements. Water re-use and recycling is always a desired goal to minimize environmental impact and reduce operating costs. Proper separation, clarification, and filtration is required to make water re-use possible, and when not feasible, to ensure regulatory compliance for disposal or discharge.

Building Materials Manufacturing: Representative Projects and Systems for Pollution Control
800 GPM Thickener Clarifier to separate dense, sticky solids contained in the liquid stream at a gypsum manufacturing plant. Solids are now properly agitated and pumped out in a timely manner, preventing material setting that had previously damaged equipment and stopped production.
High efficiency Cartridge Dust Collectors for brick and terra cotta manufacturing facility to exhaust mills and protect employees from exposure to crystalline silica dust. The plant had several material transfer and processing stations, each requiring a custom hood, ductwork, collector, and control system.
Multi-Stage Oil Mist Collector to remove heavy oil droplets, smoke, and sub-micron vapors for a synthetic fiber plant’s manufacturing operations. The four-stage system operates at >95% efficiency treating 0.3 micron sized particles.
