Abstract: The present invention relates to a method of continuously recycling thermoset plastic waste. The method includes crushing the thermoset plastic waste into pieces with a diameter size suitable for being fed into an extruder. The method also includes purifying the thermoset plastic waste by cleaning the thermoset plastic waste using a cleaning agent to remove contaminants from the thermoset plastic waste. The method also includes extruding the thermoset plastic waste by using supercritical solvent.

Abstract: A low printing temperature thermoplastic filament composition for fused filament fabrication 3D printing is described. The filament includes polycaprolactone in an amount from 70 to 90 wt %, at least one thermoplastic polymer having a melting temperature between approximately 60° C. and approximately 90° C. in an amount from approximately 10 to 30 wt %, at least one antioxidant, and at least one plasticizing agent. This 3D printing filament can be printed out at temperatures below 100° C. and no heated print bed is needed, which saves energy and minimizes the complexity of 3D printer. Besides the low printing temperature, this 3D printing material is bio-friendly which makes it safe for household use.

Abstract: Disclosed is an environmentally friendly recycling process for expanded polystyrene (EPS) wastes using dissolution process and supercritical CO2 extraction process. The recycling process may enable condensing an expanded polystyrene (EPS) by dissolving the EPS into a solvent and one or more additives thereby obtaining an expanded polystyrene (EPS) solution. The recycling process may further enable purifying the EPS solution using at least one of a filtration process and a separation process in order to obtain a purified expanded polystyrene (EPS) solution. Further, the recycling process may further enable extracting the polystyrene from the solvent in the purified expanded polystyrene (EPS) solution using a supercritical CO2 extraction method in order to obtain a recycled polystyrene. The recycling process enables in significant reduction of the volume of EPS thereby saving the logistical cost as well as facilitating increase in quantity, quality and purity of the recycled polystyrene.
