This section examines how TRI chemical wastes are managed within the cement manufacturing sector (defined as facilities reporting their primary NAICS code as 327310).
Although relatively few facilities in the cement manufacturing sector report to TRI, the operations of these facilities result in substantial quantities of TRI waste managed and released, as well as being a notable contributor to the country's greenhouse gas emissions. The cement manufacturing sector is unique among TRI sectors because of its high volume of waste combusted for energy recovery. Cement manufacturers often use waste from other facilities, such as spent solvents, as fuel to produce heat needed for the manufacture of cement.
This map shows the locations of the cement manufacturing facilities that reported to TRI for 2020, sized by their relative releases. Click on a facility for details on its TRI reporting.
Cement Manufacturing Facilities Reporting to TRI, 2020
View Larger Map
For 2020, 113 facilities in the cement manufacturing sector reported to TRI. Cement manufacturing is an energy-intensive process in which limestone and other ingredients are heated in a kiln. To maintain the high temperatures required to produce cement, facilities use a variety of fuels, including chemical wastes. This sector manages a greater portion of its chemical waste by burning it for energy recovery than any other TRI-covered sector.
