Title: **Innovator David Allen: Pioneering Waste Plastic Recycling**

Introduction

David Allen, based in Portland, OR, is a notable inventor with a focus on sustainable solutions for waste management. He holds five patents that reflect his commitment to addressing environmental challenges through innovation, particularly in the recycling of plastics.

Latest Patents

Among his most significant contributions are his latest patents related to systems and methods for recycling waste plastics, including waste polystyrene. His innovative approach involves a comprehensive system designed to recover styrene monomer from waste polystyrene. This system encompasses a mixing, heating, and compacting apparatus that transforms waste polystyrene into a densified melt. Following this, a pyrolysis reactor processes the densified material alongside recycled oligomers to yield hydrocarbon gas and solids residue. The process continues with a quenching apparatus that condenses oligomers for reuse, ultimately discharging an altered hydrocarbon gas stream for further refinement. A condenser then extracts styrene to create a valuable styrene monomer oil product.
