Disclosed is a plastic trim reclaim process that recycles otherwise wasted trim into for reuse or densified composite bricks for resale. The device combines four sections to process trim scrap from a typical plastic extrusion process. The four sections comprise an input and feed section, a grinding and pre-sizing section, a compaction and sizing section, and a repelletizing and recovery section. The final product takes one of two forms: a compacted plastic brick or pellet-sized beads that can be directly reused in a new extrusion process. The compaction and sizing section utilizes a heating chamber and ram to force ground trim through an extruder, which is then cut into sections to form brick. The repelletizing and recovery section utilizes an extrusion process that feeds into a cutting plate, whereafter the sized pellets are cooled to solidify their structure prior to being vacuum transported into a container for reuse. |

A method and apparatus that produces shaped and laminate articles and recovers the excess material or flash as a part of the manufacturing process. The apparatus uses a combination of rotary die and anvil roller assemblies in successive multiple stations to cut and separate each raw material into final product portions and recyclable flash portions as each raw material enters the apparatus. The apparatus separately reclaims each raw material flash portion and delivers the flash of each material in a recyclable form to an auxiliary recycling operation. In recovering the flash, the apparatus does not adversely affect the speed or quality of production of the final shaped or laminated product. To ease removal of the flash, the apparatus applies lubricant to the blades of the rotary die. To avoid damage to web material, the apparatus uses vacuum belts to convey the web material and web product through the apparatus. |

Apparatus and systems for finishing molded articles, such as fragile starch-bound articles, having flashing or other extraneous mold material attached thereto. The containers are conveyed from the mold apparatus to the flash removal system, which preferably includes a first flashing removal subsystem that involves cutting and a second flashing removal subsystem that involves abrading. The first removal subsystem cuts or slices off all, or substantially all, of the flashing without damaging the molded article. The second removal subsystem sands or abrades any remaining nubs or protrusions not removed by the rough removal subsystem. The removed flashing is preferably recycled to a mold material feed stream in order to provide material inputs for producing new molded articles. |

An apparatus and a method for molding of polyester articles having low acetaldehyde content directly from a melt without intermediate solidification of the molten polyester. A melt to mold process is used wherein an acetaldehyde stripping agent is mixed into a polyester melt before devolatilization in a flash tank. The devolatilized polyester is pumped out of the flash tank and injected into a mold, thus forming a shaped article. The apparatus may include one or more flash tanks in one devolatilization line, or multiple devolatilization lines may be used stemming from one main polymerization reactor. The final shaped article should contain less than 10 ppm of acetaldehyde. |

A process for producing polyester articles, which generates little or no polyester waste. The process provides esterification or transesterification of one or more dicarboxylic acids or their dialkyl esters, polycondensation to produce a high molecular weight polyester, and molding or shaping of the polyester for produce the desired product. Scrap produced during the molding process is recycled back to the esterification or transesterification or polycondensation portion of the process. Optionally, the scrap may also be recycled to intermediate steps prior to the molding operation. |

The particle separator includes a housing having a top portion and a bottom portion and a longitudinal axis extending from a center of the top portion to a center of the bottom portion and a chamber defined within the housing. An inlet disposed towards the top portion of the housing is in communication with the flow of air and the supply material and is in further communication with the chamber. It is adapted to direct the flow of air and the supply material into the chamber. The chamber is adapted to facilitate swirling of the airflow and the supply material within the chamber. A cone-shaped air rotation circulator is in communication with the chamber and is configured to facilitate the flow of air directed into the chamber in a circular motion within the chamber. A selectively permeable particle screen is disposed within the chamber and is adapted to separate the fine particles from the coarse particles by permitting the fine particles to pass therethrough while the coarse particles do not pass therethrough. An exhaust outlet in communication with the chamber and the housing is configured to direct the separated fine particles and the flow of air away from the chamber while a coarse particle port disposed towards the bottom of the housing is configured to direct the separated coarse particles away from the chamber. |
