Latest Patents

Kaur’s latest patents describe systems designed to process diverse waste materials through controlled heating, oxidation, and downstream treatment.

“Deployable Multi-Zone Rotary-Kiln System and Method for Recovery of Gallium Oxide from Electronic Waste” presents a modular, containerized process for recovering gallium oxide from gallium-nitride-bearing electronic waste. Shredded material passes through a sealed feed assembly into a rotary kiln with separate operating zones for partial oxidation and conversion of gallium nitride to gallium oxide. The system also incorporates solids separation, heat recovery, and dry neutralization of acid gases and volatile metals. The resulting porous gallium oxide can be leached to produce high-purity gallium. The design may also support recovery of other materials, including indium, tin, cobalt, lithium, and rare-earth oxides.

“Thermo-Chemical Transformation of Wet Food Waste with Plastics, Biodegradable Packaging, and Fluorinated Compounds in a Multi-Annular Concentric Feed Rotary Kiln System” describes a process for treating mixed wet and dry waste without pre-drying or segregation. Its concentric feed assembly separately introduces waste, auxiliary fuel, and oxidant into a rotary kiln. Sequential reaction zones transform organic materials into fuel gases and, ultimately, carbon dioxide and water. Downstream treatment neutralizes halogen- and sulfur-containing compounds, while recovered flue-gas heat can produce steam or hot water.
