Karel Kolomaznik

1998 Associate Laureate, Applied Technology
Czech Republic, Born 1938


Project Goal

Improve technology to recycle potentially toxic waste

Location: Czech Republic

"Dr Kolomaznik’s unique contribution is in demonstrating that this process could be run on an industrial scale [and in] successfully identifying markets for the protein products.”

Chromium salts are widely used in leather tanning. Usually the tanned wastes are not dangerous to health and are stockpiled in open-air dumps in the form of leather shavings. But acid rain, common across the industrial world, can leach harmless chromium from shavings into groundwater and transform it into deadly chromium that causes liver and bladder cancer.

Karel Kolomaznik, a Czech professor, has improved a technology that recovers the potentially dangerous chromium for reuse in the tanning cycle, and has shown it can be used on an industrial scale. He is now researching ways to make the tanning process completely waste-free.
