Title: Gireeshkumar Padmanabhan Nair and Waste-to-Energy Innovation.

Introduction

Gireeshkumar Padmanabhan Nair is an inventor associated with Kerala, India, and Simple Approach Systems, Inc. His work includes an invention for processing mixed wet and dry waste through a thermo-chemical transformation system.

Latest Patents

Nair is associated with 1 patent, titled “Thermo-chemical transformation of wet food waste with plastics, biodegradable packaging, and fluorinated compounds in a multi-annular concentric feed rotary kiln system.”

The invention uses a rotary kiln with a multi-annular feed assembly. A central conduit introduces wet food waste mixed with plastics, biodegradable packaging, and fluorinated materials. Separate annular passages supply auxiliary fuel and oxidant gas under controlled conditions. Sequential reaction zones transform organic materials into combustible gases and, ultimately, carbon dioxide and water. Downstream treatment uses calcium oxide to neutralize hydrogen halides and hydrogen sulfide, while heat recovery from flue gas can produce steam or hot water.

The system is designed to process heterogeneous waste without pre-drying or segregation. Its compact, scalable configuration supports co-processing and energy recovery.
