Devices, systems, and methods for recycling plastic
Systems for recycling waste plastic can include cartridges that are selectively sealable. Some cartridges can have elongated receptacles that improve heat transfer to plastic feedstock within the cartridges.
1. A cartridge for use in recycling plastic, the cartridge comprising:
a selectively sealable opening through which plastic feedstock can be introduced into an interior of the cartridge;
a body that defines an upper cavity into which a plastic feedstock can be received;
an evacuation port in fluid communication with the upper cavity, wherein the evacuation port is configured to permit removal of gas from the cartridge when the opening is sealed; and
a plurality of elongated receptacles that extend away from the body, wherein each of the receptacles defines a lower cavity that is in fluid communication with the upper cavity of the body such that heated gas can freely move from the lower cavities into the upper cavity.
2. The cartridge of claim 1 , wherein the cartridge is configured for use with a plastic feedstock that reduces in volume by a known amount when melted such that the cartridge is sufficiently large to receive a sufficient amount of un-melted plastic feedstock therein such that when the opening of the cartridge is sealed and the plastic feedstock is melted, the plastic feedstock fills at least about 75 percent of a volume defined by the plurality of receptacles.
3. The cartridge of claim 1 , wherein a longitudinal length of one or more of the plurality of receptacles is greater than a height of the body.
4. The cartridge of claim 1 , wherein a transverse dimension of the body is no less than about five times as large as one or more transverse dimensions defined by the plurality of receptacles.
5. The cartridge of claim 1 , wherein the each of the plurality of receptacles extends away from the body in the same direction.
6. The cartridge of claim 1 , wherein the number of receptacles is no fewer than five.
7. The cartridge of claim 1 , further comprising a counterbalance positioned opposite the evacuation port.
8. The cartridge of claim 1 , further comprising a lid that comprises a lift attachment and a guidance channel that is configured to direct a hook toward the lift attachment.
