A number of other changes were also made to increase cathode life. The aluminum plate thickness was increased from 4.7 to 6.2 mm in 1995, then again to 7.0 mm thick in 1999 to take advantage of using scrap jumbo cathode plates from Canadian Electrolytic Zinc. The cathodes were also fitted with permanently attached polyethylene side strips. These required less manual attention than the previously used clip-on strips, thereby improving machine performance.

At Canadian Electrolytic Zinc, Valleyfield, Quebec, the main pollutant is sulfur-based gases. Three indoor and two outdoor sites are being tested, and 2-year results are given in Table 2.34 (except for the roaster, which has 5-KX) ppm SO2, traces of SO3, and dust, but is dry and has a known lower corrosion rate from tests on zinc-coated steels). Qualitatively, the results were comparable to those in the acid areas of the pulp and paper plant.
