Facilities of Holcim (formerly Holnam) Cement
Built in mid-1980's as the area's
first modern "dry process" plant, Holcim has two kilns that are mirror
images of each other. Both have scrubbers and other modern pollution
controls missing in the older kilns at TXI and North Texas. Because both its
plants have these features, it is the only cement plant in Midlothian to see
its pollution permit numbers actually decrease in recent years.
It has been burning chipped tires since 1995. Holcim's permit restricts
tire chips to no more than 45% of the total hourly fuel. The plant also can
burn wood chips and "oil filter fluff." They too dump their cement kiln dust
in an on-site quarry. Holcim is Swiss-owned.
