Abstract
The present disclosure includes a method of capturing CO2 gas from a cement manufacturing plant and purifying the CO2 gas to provide recycled CO2 gas, pelletizing recycled polymeric material, converting the captured CO2 gas to supercritical CO2 gas, contacting the supercritical CO2 gas with the recycled polymeric material in an extruder to provide a CO2-laden polymeric material; plasticizing and extruding the CO2-laden polymeric material; forming pellets of the plasticized and extruded CO2-laden polymeric material; and injecting the pellets into a mold to form a plastic article of manufacture.
Claims7
A method for forming a plastic article of manufacture using recycled CO2 and recycled polymeric material, the method comprising the steps of:
- capturing CO2 gas from a cement manufacturing plant and purifying the CO2 gas to provide recycled CO2 gas;
- pelletizing recycled polymeric material;
- converting the captured CO2 gas to supercritical CO2 gas;
- contacting the supercritical CO2 gas with the recycled polymeric material in an extruder to provide a CO2-laden polymeric material;
- plasticizing and extruding the CO2-laden polymeric material;
- forming pellets of the plasticized and extruded CO2-laden polymeric material;
- and
- injecting the pellets into a mold to form the plastic article of manufacture.
A closed system for manufacturing concrete-based articles of manufacture including CO2-encapsulated plastic aggregate, the system comprising:
- a CO2 purifying station for purifying CO2 gas captured from a cement manufacturing process;
- a first pelletizer for pelletizing recycled polymer material;
- a conversion tank for converting captured CO2 gas to supercritical CO2 gas;
- an injector for supplying supercritical CO2 gas from the conversion tank;
- an extruder connected with the injector and the pelletizer wherein when the pellets of recycled glass material are provided in the extruder, the pellets are melted and the melted pellets are injected with a supercritical CO2 to provide a glass material having CO2 encapsulated therein;
- a second pelletizer for pelletizing polymeric material having CO2 encapsulated therein into an aggregate, and
- a mold for forming concrete-based articles of manufacture having the aggregate with polymeric material with CO2 encapsulated therein.
A method for forming an article of manufacture using recycled CO2 and recycled glass material, the method comprising the steps of:
- capturing CO2 gas from a cement manufacturing plant and purifying the CO2 gas to provide recycled CO2 gas;
- providing recycled glass material;
- converting the captured CO2 gas to supercritical CO2 gas;
- contacting the supercritical CO2 gas with the recycled glass material in an extruder to provide a glass material having CO2 entrapped therein;
- extruding the glass material having CO2 entrapped therein;
- and,
- forming pellets of the extruded glass material having CO2 entrapped therein.
A closed system for manufacturing concrete-based articles of manufacture including CO2-encapsulated glass aggregate, the system comprising:
- a CO2 purifying station for purifying CO2 gas captured from a cement manufacturing process;
- a mill drum for reducing the size of the recycled glass material
- a conversion tank for converting captured CO2 gas to supercritical CO2 gas;
- an injector for supplying supercritical CO2 gas from the conversion tank;
- an extruder connected with the injector and the pelletizer wherein when the recycled glass is provided in the extruder, the glass is melted and the melted glass is injected with a supercritical CO2 to provide a glass material having CO2 encapsulated therein;
- a second pelletizer for pelletizing the glass material having CO2 encapsulated therein into an aggregate, and
- a mold for forming concrete-based articles of manufacture having the aggregate with polymeric material with CO2 encapsulated therein.
