Embodiments relate to a polyester film, preparation method thereof and method for reproducing polyethyleneterephthalate (PET) container using same, the crystallization temperature (Tc) of the polyester film is not measured or is 70? C. to 130? C., as measured by differential scanning calorimetry, whereby it is possible to easily control the crystallinity. Accordingly, the polyester film has excellent shrinkage characteristics and recyclability, and clumping rarely occurs even if it is dried at high temperatures for a long period of time in the regeneration process.

A process for separation and recovery of waste carpet components, wherein waste carpets are predominantly composed of a face fiber material, a backing material and an adhesive coating which includes latex and filler. Virtually all of the filler, i.e. calcium carbonate, is removed prior to fine grinding and passing the mixture to a high speed centrifuge for separation of the face fiber material from the backing material. A high friction washer is disclosed which separates the face giver material, the backing material and the adhesive coating. The fine grinding of the material to be recycled may be done only once before passing the mixture to the centrifuge by which the loss of the fiber material is highly reduced before its separation into face fiber and backing material and also the life time of the fine grinder and the centrifuge can be prolonged.

A system for densification of recycled pre-preg fibers may include a cutting device configured to receive the recycled pre-preg fibers having various lengths, and cut the recycled pre-preg fibers to produce cut fibers having a desired length, and a mixer configured to mix wetted, cut fibers to generate bound fibers having an increased bulk density relative to a bulk density of the cut fibers.

A recycling device and a recycling method for laminar structures bonded by cured adhesive are disclosed. The recycling device comprises a barrel device, a molten salt supply equipment and a transfer equipment. The barrel device accommodates the laminar structures. The molten salt supply equipment fills a specially formulated molten salt into the barrel device, and also discharges the molten salt from the barrel device. The transfer equipment transfers the laminar structures between the outside environment, the temperature-adjusting space and the barrel device. Through the design of the barrel device, molten salt supply equipment and transfer equipment, molten salt is used to heat and pyrolyze the solidified adhesive in the laminar structures to obtain recycled plate-like objects with a whole structure, so it can improve the shortcomings of conventional methods for recycling laminar structures such as direct heating pyrolysis, mechanical peeling or scraping.

An extruded polystyrene processing device for processing extruded polystyrene includes a processing plant which includes a chopping unit for chopping extruded polystyrene into chopped pieces. The chopping unit is connected to a solvent bath unit for submerging the chopped pieces in a solvent for eliminating air bubbles in the chopped pieces. The solvent bath unit is connected to a conveyor unit for rinsing the chopped pieces and the conveyor unit is connected to a freezing unit to subsequently freeze the chopped pieces. The freezing unit is connected to a grinding unit for grinding the frozen chopped pieces into a granular material for subsequent collection and transportation to a waste management facility. In this way the processing plant reduces the total volume of the extruded polystyrene prior to being handled by the waste management facility.

A method for recycling waste batteries containing electrolytes includes crushing the waste battery in a solution containing an amphiphilic solvent. A system for recycling a waste battery includes a crushing tank in which a waste battery including an electrolyte and a solution including an amphiphilic solvent are contained, a filtration tank for separating the crushed material of the waste battery from the solution, and a separation tank for separating the electrolyte dissolved in the solution from the solution.
