Title: Innovations by John D Graham in Hemp Composite Technology

Introduction

John D Graham is an innovative inventor based in New York, NY (US). He holds a total of 7 patents that focus on environmentally friendly construction materials. His work primarily revolves around the use of hemp feedstocks to create sustainable alternatives to traditional construction boards.

Latest Patents

One of his latest patents is a system and method of extruding a hemp composite board using hemp feedstocks. This method provides a way to produce environmentally friendly, mono-extruded hemp composite boards (EHB). By utilizing hemp fiber and hemp hurd in combination with virgin and/or recycled binders, Graham's invention creates preferable substitutes for traditional construction boards. The process involves steps of processing hemp hurd/fiber and injecting it into an extruder along with a binder. Additionally, waste products from other production streams can be incorporated to reduce costs and waste. The resulting EHB is structurally superior to traditional boards due to the unique characteristics of dispersed hemp materials and their encapsulation in a binder. Furthermore, the use of an extruder allows for the creation of complex shapes that are challenging to achieve with conventional materials.

Another significant patent is the mono-extruded hemp composite board (EHB). This invention combines hemp feedstocks with binder materials and extrudes them into an extrudate sheet. This environmentally friendly alternative enhances the physical characteristics of traditional construction materials. The extrudate sheet produced is structurally superior due to the properties of hemp feedstocks, including lower hygroscopicity and higher resistance to pests and mold. The downstream extrusion arrangement allows for customization, increasing the potential for innovative final products.
