History - 1980s
By the mid-1980s, the economy and local markets had fully recovered and Permanente’s out put had kept pace. The rebuilding also installed facilities that have kept Permanente abreast of increasing environmental demands. Once again, Permanente had taken a bold step to prepare for the future.
Building for the Future...
The modernization of the Permanente plant could not have been planned at a better time; the early ‘80s brought a construction lull, offering an excellent opportunity to devote time and energy to rebuilding.

The Permanente kiln and raw grinding mill was completely rebuilt and put into operation in the summer of 1980. Above, workers brick the new kiln.
A New Permanente...
By March, 1981, the new plant was complete, boasting the largest single preheater kiln in the U.S. and an annual capacity of 1.6 million tons. In September 1981, the last bag of wet-process cement was sacked, and the six old kilns shut down forever. The two 220-foot concrete stacks, landmarks for more than 40 years, were felled one year later.
In all, $112 million had been invested to literally rebuild Permanente. Fuel consumption per ton of cement manufactured had been cut 35%, and emissions had been reduced significantly.

New Horizons...
With increasing globalization of the cement industry, Kaiser Cement was purchased in 1986 by Hanson PLC, a British firm with an outstanding record of profitable growth in both the U.K. and the U.S.
Permanente’s location, efficient plant and extensive raw material reserves continue to assure it a key role in a changing industrial environment. By 1989, Permanente was again the heart of Kaiser Cement’s manufacturing strength, supplying nearly one-third of all the cement used in Northern California.
