In 2019, the Argos Harleyville 水泥 Plant had a focus on improving the overall energy management by reducing kiln specific heat consumption and increasing the utilization of the new vertical 水泥 mill (VCM), which 反过来 lowered the overall power consumption in producing 水泥. The Harleyville Plant achieved both of those goals, reducing the kiln SHC by 7.5% and producing all Type I 水泥 in the VCM, which lowered the power consumption by 13%. The Harleyville Plant also has had a very long and positive history in alternative fuel usage, and in 2019 the plant achieved one of its highest alternative fuel substitution rates at 27% substitution to tradition fuels.
The Ash Grove Midlothian plant received air permits and operates a whole tire burning system utilizing a first-in-the-USA “hot disk” system that is supplied with whole tires from a nearby tire recycling company. The use of a unique high-angle sandwich belt conveyor system has enabled the plant to convert from inefficient whole tire burning as a fuel source to highly efficient and cost-effective chipped tires. The high-angle sandwich belt conveyor system for chipped tires has increased tire burn consumption by 500%-600% over the previous whole tire system to achieve guaranteed tire burn rates allowed by the air permit. 这, 反过来, helps reduce tire disposal to landfills while also displacing fossil fuel consumption at the plant. The plant also received continuing certification in 2019 under ISO14001:2015 by Eagle Registrations.
2019年4月, GCC’s Odessa Plant completed installation of a Selective Non-Catalytic Reduction (SNCR) System for NOx emission reduction. 调试活动之后, an optimization protocol was executed to define the most efficient operational conditions, which both maximized the NOx reduction and minimized the ammonia slip (i.e. 多余的试剂). 为了做出这个决定, GCC developed a unique approach to the programming of the SNCR system control loop, which has resulted in more stable emission control and lower ammonia emissions to atmosphere while maintaining the required NOx emission limit.
为了解决安全问题, 经济及环境考虑, LafargeHolcim’s Holly Hill plant relocated a diversion canal, restoring it to an ecologically beneficial stream similar to its original path. In 1989, 在LafargeHolcim的所有权之前, 首页 Branch was diverted from its original path by means of an upland ditch with vertical sides, which was not representative of a natural stream channel as it was void of floodplains, 深度和宽度变化, 和蜿蜒. There were concerns that the upland dug diversion canal would undergo structural failure and collapse, 洪水的采石场, 哪些会威胁到员工和设备. A collapse would also potentially result in environmental damage to the adjacent Four Hole Swamp if flow was interrupted for an extended period.
多年的, multi-million-dollar project played a critical role in quarry water management by significantly reducing the groundwater infiltration, 以及, minimizing the potential collapse hazard of the existing diversion canal. The stream was designed to vastly improve on the existing diversion canal, 紧跟着原来的水流到达四洞沼泽, and incorporate sinuosity and floodplains into the upstream portion. It also includes a hardwood woodland buffer along most of the new channel route, providing enhanced habitat for indigenous plant and animal species.
In 2019, Roanoke 水泥 Company’s broad and varied outreach was demonstrated in plant tours, 校园活动, 非现场演示, 文章, 时事通讯, 荣誉, 奖励和认可, 以及主要工厂计划的沟通. Periodic publications brought the plant’s news on developments, 比如它的“零废物”计划, 对客户和社区. Educational experiences on campus served to make both students and environmental professionals familiar with RCC’s work. Exciting developments on-site reached political leaders and “green” builders who scheduled visits and toured the operations and surroundings.
Three years ago, Lehigh 水泥 undertook a Haines Branch Stream mitigation project, which spanned 2.2 miles, and the company has been monitoring the area since project completion. In 2019, after three years of monitoring and allowing ample time for the proper flourishing of flora and fauna, the results and benefits of the project became highly visible. 结果改善了水质, benthic macroinvertebrates and fish populations in the restored section of the Haines Branch Stream have increased in quantity and diversity. 除了, the improvements are attracting numerous wildlife to the region, 包括白尾鹿, 浣熊, 狐狸, 东棉尾兔兔, 貂, 土狼, 负鼠, 大蓝鹭, 木鸭子, 野鸭, 禁止猫头鹰, 北部闪烁, 冠蓝鸦, 狙击, 和嵌套鸣鸟.
