Papers by Keyword: Recovered Milk Bottles

Abstract: Wastes such as saw dust (Pinus Radiata) and milk bottles (High Density Polyethylene - HDPE) are available in abundance. Composite decking materials, consisting of different weight percentages (60%, 70% and 80%) of saw dust and recovered HDPE, were extruded using a co-rotating, conical, twin screw extruder with a decking-profile die. The extruded decking materials were evaluated on their surface finish and shape conformance. The extruded decking materials were tested in accordance with the appropriate ASTM standards to determine their water absorption, thickness swell, static coefficient of friction, weathering and flexural (four-point bending) properties after they met the required quality ratings.

Abstract: Wastes such as saw dust (Pinus Radiata) and milk bottles (High Density Polyethylene - HDPE) are available in abundance. HDPE bars and composite bars, consisting of different volume percentages (50%, 60% and 70%) of saw dust and recovered HDPE, were extruded using a co-rotating, conical, twin screw extruder with a slit-profile die and an innovative sizing-cooling box. The extruded bars were evaluated on their surface finish, shape conformance and materials distribution across the cross-section. Mechanical testing of the extruded bars was carried out using appropriate ASTM standards after they met the required quality ratings.
