Six cement plants received special recognition for their commitment to improving the environment and their communities at the 14th Annual Cement Industry Environment and Energy Awards, presented by the Portland Cement Association (PCA) and Cement Americas magazine at PCA's Fall Meeting in Chicago.

The awards honor individual cement facilities that exemplify the spirit of continuous environmental improvement and support this spirit with action. These plants went beyond government regulations and local laws to ensure that their processes and policies contributed to making their communities better places to live and work.

“Although it is one of the most highly regulated industry sectors in the North America, cement companies are consistently challenging manufacturing policies and procedures and are on the forefront of new technologies to make their plants more energy efficient and to become better stewards of the land and resources,” said Cary Cohrs, chairman of the PCA Board of Directors. “Making a quality product is not enough. These and other cement companies take extra steps to ensure their communities are excellent places to work, live and learn.”

Six categories recognized plants throughout the United States: Overall Environmental Excellence, Outreach, Environmental Performance, Land Stewardship, Innovation and Energy Efficiency. Twenty-one North American cement plants were nominated for the awards.

The awards program was created in 2000 by the Portland Cement Association as part of its environment and energy strategic plan for the U.S. cement industry. The awards honor activities conducted during the previous calendar year, and the program is open to any cement manufacturing plant in North America. Judges for the 2013 awards program included representatives from U.S. EPA-Energy Star, Wildlife Habitat Council, U.S. Geological Survey, World Wildlife Fund, and Cement Americas.

In 2013, the Brooksville plant attended monthly Groundwater Guardian meetings hosted by the Hernando County Water Utility along with county representatives, consultants and the general public. Water use and conservation topics are discussed to educate the public about protecting water resources. The plant also sponsored the “Your water, Your World” event hosted by the Hernando County Utilities Department. Additionally in 2013, Cemex signed the Cemex Water Policy, which defines the strategy for responsible water management, and acts as a framework for the development of local water conservation and efficiency strategies across Cemex operations worldwide.

The Cemex Brooksville plant replaced 16,078 tons of coal by consuming more than 24,500 tons of alternative fuels. The plant achieved an 18.8 percent alternative fuel substitution rate, thus reducing the site's CO2 footprint, and conserving natural resources for the future.

ENVIRONMENTAL PERFORMANCE
Finalist: Cemex USA, Odessa, Texas

The Odessa plant designed and constructed a completely enclosed clinker storage system that includes three clinker silos. The new clinker silos were built in order to reduce the exposure of clinker to the wind and weather. The multi-million dollar construction of the clinker storage silos goes above and beyond current environmental regulations. With these new clinker silos, Cemex hopes to reduce approximately seven tons of permitted particulate matter emissions per year.

Additionally, the plant replaced their old baghouse with one that uses modern technology, using pulse jets and negative pressure with modern fabric filters and a stack vent to enhance dust control practices.

ENVIRONMENTAL PERFORMANCE
Runner Ups:

St. Marys Cement’s Charlevoix, Mich., plant was also a runner up for the Environmental Performance Award. The plant won the Land Stewardship Award.


LAND STEWARDSHIP
Winner: St Marys Cement, Charlevoix, Mich.

StMarys LS 335x400The Land Stewardship category recognizes efforts to protect and enhance the surrounding land. Several St. Marys outreach initiatives in 2013 involved partnerships with the community on biodiversity conservation efforts. These included U.S.-31 Corridor Enhancement Project, and the plant’s fourth eagle release. Other community related efforts include the Phragmites Removal Project and the Rails to Trails Project.

In 2013, St Marys Cement was granted a permit by the Michigan Department of Environmental Quality, which allowed the plant to discontinue the use of Lake Michigan water for process noncontract cooling and consumptive needs, and instead use the plants own quarry dewatering water. This means that 500 million-plus gallons of water will no longer be drawn from Lake Michigan annually.

Additionally, in September 2013, St Marys Cement announced that the plant achieved recertification in all three ISO systems.

LAND STEWARDSHIP
Finalist: Cemex USA, Demopolis, Ala.

Cemex Demopolis actively manages approximately 1,620 acres for wildlife conservation. The mission of Cemex’s Wildlife at Work program is to responsibly manage the land within their operations to protect and enhance ecosystems and biodiversity. Partnering with Demopolis High School’s Industrial Arts class, nest boxes were built and installed for wood ducks and song birds to provide supplemental nesting habitat along the quarry pond and open grassy areas of the property. The Cemex Demopolis wildlife team is monitoring the seven wood duck boxes and 16 songbird boxes to ensure that they are successful, with many years of successful clutch hatches as of spring 2014. All of the wood duck boxes have been utilized by wood ducks, and approximately half of the songbird boxes have also been utilized.

In November 2013, the Demopolis plant was awarded the Wildlife Habitat Council’s Wildlife at Work certification for their voluntary, employee-based wildlife habitat enhancement efforts that exceed regulatory requirements.

INNOVATION
Winner: Lafarge North America Inc., Paulding, OhioLafargeI I 400x300

The Innovation Award recognizes cement industry leaders in the development and application of innovative technologies and techniques relevant to environmental protection or energy efficiency.

The Lafarge Paulding facility fully captured small grain cement kiln dust (CKD) for return back to the kiln feed bed by briquetting the CKD powder prior to reintroduction to the feed bed. Briquetting machines have been around for many years, however, this may be the first time the process has been used to improve CKD recycling rates.

After an initial and successful trial using smaller equipment, the Paulding plant installed a larger briquetting machine and feed system to the plant’s kiln systems. As a result, the plant was able to return 1 ton of CKD per hour to the hood of the kilns.

LafargeII I 400x300The project increased clinker production, reduced CKD going to the landfill, increased kiln performance factor, reduced the chlorinated grinding aid accelerator, decreased Specific Heat Consumption, and reduced CKD haul truck hours to the landfill. With a yearly savings of $1 million, the project payback period was less than eight months.

INNOVATION
Finalist: Buzzi Unicem USA, Inc., Maryneal, Texas

In 2013, the Maryneal plant commissioned the first Horomill grinding system in the United States, replacing a decades-old, inefficient, cement grinding system. The energy savings have been significant. From January 2009 through June 2013, the power consumption rate of the plant’s grinding system was 78.3 kW/h per short ton of cement produced. Between July and December 2013, Horomill power consumption averaged 47.7 kW/h per short ton of cement produced, representing a 40 percent reduction in power consumption and related greenhouse gas emissions. Additional benefits from this new system include reduced noise levels and less off-spec cement. The plant has also seen a reduction in water consumption rates.
