METHOD FOR PRODUCING AN RPET PLASTIC MATERIAL FOR USE IN A THIN WALL INJECTION MOLDING PROCESS AND HOLLOW BODY PRODUCED IN THE THIN WALL INJECTION MOLDING PROCESS
20240100742 · 2024-03-28 ·

The invention relates to a method in which a starting material for injection-molding, having a viscosity of between 0.50 and 0.7 dL/g, is produced with the aid of a chain breaker from a recycled post-consumer PET having a viscosity of between 0.72 and 0.86 dL/g according to ASTM D4603 and a copolymer fraction of at most approximately 3%. In the method, the comminuted and dried PET material is melted and decontaminated to such a degree that it is suitable for applications in the food sector and the consumer goods sector. A chain breaker is added to the rPET material in the melt of the recycling extruder and/or preferably the melt of the injection unit in order to lower the viscosity and to enrich the PET with copolymers.

20240082504 · 2024-03-14 ·

A needle shield remover for a medicament delivery device is presented that has a metal tubular body, a proximal part, a distal part, and a substantially circular cross-section, where the tubular body is arranged with a slot extending from a distal end of the body, at least half the length of the body, towards a proximal end, such that at least the distal part of the body may flex radially outwards to exert a radially inwardly directed clamping force on a needle shield accommodated by the body.

MOLECULAR ENCODING OF RECYCLING INFORMATION

Recycling information is associated with objects through the use of molecular tags. The recycling information may describe the type of material that the object is made from as well as provide instructions for recycling. The molecular tags may be polynucleotides or other types of molecules including inorganic molecules. The molecular tags may be embedded within the object or attached to the surface of the object. At the end of the object's life, the molecular tags are read and the recycling information is used to appropriately recycle the object.

COMPOSITE PANELS WITH ADHESIVE AND SEPARATE FRAGMENT LAYERS

A panel including a first layer including fragments from a first blend of paper fragments of a first size and plastic fragments of a second size, a second layer including fragments from a second blend of paper fragments of a third size and plastic fragments of a fourth size, the third size being different from the first size, and the fourth size being different from the second size, and a third layer comprising fragments from the first blend. The second layer is disposed between the first layer and the third layer.

Methods for manufacturing bulked continuous filament from recycled PET
11911930 · 2024-02-27 · ·

A method of manufacturing bulked continuous carpet filament that includes providing a polymer melt and separating the polymer melt from the extruder into at least eight streams. The multiple streams are exposed to a chamber pressure within a chamber that is below approximately 25 millibars, or another predetermined pressure. The streams are recombined into a single polymer stream. Polymer from the polymer stream is then formed into bulked continuous carpet filament.

METHOD FOR RECYCLING WASTE IN THE FORM OF FLAKES
20240058993 · 2024-02-22 ·

The invention relates to a method for recycling waste in the form of flakes containing plastics-based materials, the flakes; compacting the flakes and feeding them into a plasticizing tool; melting and kneading the flakes in the plasticizing tool; injecting the extruded material under high pressure into a mould to form a component; using the decomposition gases generated by the heating and the pressurizing of the material recycled in the plasticizing tool to lubricate the material as it is injected into the mould and to compensate for the shrinkage of the material as it cools without supplying additional gas; cooling the mould; extracting the component from the mould.

SYSTEMS AND METHODS FOR MANUFACTURING BULKED CONTINUOUS FILAMENT FROM COLORED RECYLED PET
20240042717 · 2024-02-08 ·

A system comprising: (1) a grinding unit configured to receive and grind recycled PET bottles into a group of polymer flakes comprising up to about ten percent colored polymer flakes and balance substantially clear polymer flakes; (2) a washing unit configured to wash the group of polymer flakes; and (3) an extruder configured to extrude material in a plurality of different extrusion streams. The extruder may be further configured to: (1) receive a concentrate-polymer mixture comprising a mixture of the polymer flakes and a color concentrate; (2) melt the concentrate-polymer mixture to produce a polymer melt; (3) reduce a pressure within the extruder; and (4) pass the polymer melt through the extruder so that the polymer melt is divided into the plurality of extrusion streams. The system may then filter the polymer melt through at least one filter and form the polymer melt into bulked continuous carpet filament.

Process for manufacturing fully recyclable mining screens
11890785 · 2024-02-06 · ·

The present invention provides an environmentally-friendly, fully recyclable composite mining screen which has sufficient rigidity to replace existing metal and metal covered plastic mining screens. The inventive composite screen insert contains stiff reinforcing fibers (glass, carbon, etc.) and exhibits the rigidity of metal and metal-covered plastic mining screen inserts so as to minimize deflection in use. The inventive mining screen is also completely recyclable because at the end of its useful life, the broken and used screen can be ground into polymer particles and the particles incorporated into new screens or other parts.
