After 13 years in environmental engineering, I’ve designed, commissioned, and debugged more acid scrubbers than I can count. From HCl […]
After coating and calendering, the electrode sheet is a continuous ribbon of active material on metal foil — hundreds of
Every lithium battery has an anode. For 30 years, that anode was graphite. For the next 30 years, it probably
The last major revision of ISO 14001 was in 2015—eleven years ago. In that time, climate disclosure went from voluntary
Most factories run emergency drills. Most factories do them badly. The typical drill: sound the alarm, everyone walks to the
Electrolyte filling—the step where liquid electrolyte is injected into a sealed or semi-sealed battery cell—looks simple. A needle dispenses liquid
Electroplating wastewater is not one wastewater. It’s at least three chemically incompatible streams that must be collected, stored, and treated
Every process plant has pipes. Thousands of them. And every experienced plant designer has a story about a piping mistake
When a lithium-ion battery reaches end of life, everyone focuses on the metals—cobalt, nickel, lithium. The electrolyte? Usually burned off
A dust collection system that doesn’t capture dust at the source is just an expensive fan moving dirty air around
The cathode is 30-40% of a lithium-ion cell’s cost and determines its voltage, capacity, safety characteristics, and roughly half its
The A²O process—Anaerobic-Anoxic-Oxic—is the most widely deployed biological nutrient removal (BNR) configuration in the world. It removes organic carbon, nitrogen,
