Technical Abstract: Polystyrene is one of the most widely used plastics and is commonly produced in three forms: 1) Extruded polystyrene – disposable utensils, CD/DVD cases, yogurt containers, smoke alarm housing, etc.; 2) Expanded polystyrene foam – molded packaging materials and packaging "peanuts"; and 3) Extruded polystyrene foam – insulation boards. Extruded polystyrene foam is commonly sold under the trademark name of "Styrofoam". Polystyrene packaging and insulation is a multibillion dollar a year industry. Since polystyrene is non-biodegradable, a biodegradable material that is eco-friendly is being sought as a substitute for packaging and insulation board consumers. Ecovative Design, LLC has developed a process whereby they can produce an eco-friendly packaging and insulation board product. The objective of this research was to develop and evaluate various blends of waste material from cotton gins, commonly referred to as cotton gin trash/cotton gin waste, as a substrate in Ecovative’s process. Tests were conducted to evaluate six cotton waste blends to ASTM standards as well as conventional polystyrene. Properties evaluated included: density, strength (compressive and tensile), dimensional stability, modulus of elasticity, sterilization efficacy, colonization rate, thermal conductivity, flame retardance, energy dissipation, and accelerated aging. Results revealed blends that were superior or equal to ASTM standards and polystyrene. One of the higher performing blends was used to launch Ecovative’s product (EcoCradle TM) with two Fortune 500 companies during the last few months.
