Latest Patents

Mathew’s recent inventions address two distinct challenges in waste processing.

“Deployable multi-zone rotary-kiln system and method for recovery of gallium oxide from electronic waste” describes a modular rotary-kiln process for recovering gallium oxide from gallium-nitride-bearing electronic waste. The system uses sequential heating zones, controlled oxidant injection, and kiln rotation to convert gallium nitride into gallium oxide. It also incorporates heat recovery and dry neutralization to manage acid gases and volatile metals without producing liquid effluent. The resulting porous gallium oxide can be leached to obtain high-purity gallium. The containerized design is intended for field deployment and may be adapted to recover other valuable materials from electronic waste.

“Thermo-chemical transformation of wet food waste with plastics, biodegradable packaging, and fluorinated compounds in a multi-annular concentric feed rotary kiln system” concerns processing mixed wet and dry waste in a rotary kiln. Its concentric feed assembly separately introduces waste, auxiliary fuel, and oxidant, while the kiln’s sequential reaction zones transform organic materials and support energy recovery. The process is designed to handle heterogeneous feedstocks without pre-drying or segregation. Downstream treatment neutralizes halogen- and sulfur-containing compounds, and recovered flue-gas heat can produce steam or hot water.

Career Highlights

Mathew’s patent work centers on practical, scalable approaches to waste treatment. One invention targets the recovery of valuable metals and oxides from electronic waste, while the other aims to process mixed waste streams and capture useful energy. Both designs emphasize integrated processing and reduced preparation requirements.
