St. Genevieve/Holcim Project:  St. Genevieve/Holcim Project Holcim:  Holcim Largest Cement Producer in the World 15 Locations across the US St. Genevieve: 16th location St. Genevieve Plant St. Genevieve:  St. Genevieve Why did Holcim choose St. Genevieve, Mo to build their largest cement manufacturing plant? An abundance of high quality limestone Close proximity to the Mississippi River 3,900 acre site has a quarry life of at least 100 years Location of Proposed Facility:  Location of Proposed Facility Proposed Facility:  Proposed Facility Cement Manufacturing Process:  Cement Manufacturing Process 3 main steps Quarrying and Raw Materials Preparation Clinker Production Cement Grinding and Distribution Quarrying and Raw Materials Preparation:  Quarrying and Raw Materials Preparation Quarry Extraction of limestone and other raw materials Crusher The extracted material is then crushed. Transport After the material is crushed , it is then transported to the cement plant. Clinker Production:  Clinker Production Mixing Bed Dust Filter Raw Mill Preheater Kiln Clinker Cooler Cement Grinding and Distribution:  Cement Grinding and Distribution Clinker Silo Cement Mill Logistics Environmental Hazards :  Environmental Hazards There are 2 main types associated with the cement manufacturing process. Air Pollution Particulate Matter Biggest Problem for the Cement Plant. Air Pollution:  Air Pollution Emission of several compounds such as: NOx, SOx, CO2, and other fuel combustion by products. A possibility of pollutants being emitted at every stage of process. Pyroprocessing stage emits a large portion of air pollutants: Nitrogen, water, CO2, NOx, SOx, CO, and hydrocarbons. Particulate Matter:  Particulate Matter Main source of pollution for the raw materials collection stage. Clinker dust is the biggest issue. Features such as baghouse filters and hoods are used during the process in order to minimize the clinker dust. Holcim’s Solutions:  Holcim’s Solutions Replace fossil fuels and raw materials with waste and industrial by products. The use of secondary cementing materials reduce the amount of clinker that is required per ton of cement.
