The embodiments relate to a. polyester film and a process for regenerating a polyester container using the same, which not only solve the environmental problems by improving the recyclability of polyester containers, but also are capable of enhancing the yield and productivity. The polyester film comprises a first layer comprising a first resin comprising a diol component and a dicarboxylic acid component; and a second layer laminated on one side of the first layer and comprising a second resin different from the first resin, wherein when the polyester film is cut with a polyethylene terephthalate container to form flakes and the flakes are thermally treated at a temperature of 200° C. to 220° C. for 60 minutes to 120 minutes, the clumping fraction is 8% or less.

A method of recycling laminated fabrics and laminated fabric products and producing new laminated fabrics and laminated fabric products includes the steps of shredding scrap or used laminated fabric material, melt separating the polymers, pelletizing the melt separated polymers, extruding the pelletized material with at least one virgin material to form a film, and laminating the film to a nonwoven material to form a new laminated fabric. The scrap or recycled laminated fabric products can include plastic/polymer materials having different melting temperatures. The new laminated fabric can be utilized to produce new products, such as protective covers.

A plastics recycling preparation container canister includes a stationary disc configured with cutting teeth disposed on an axial surface thereof, the stationary disc disposed substantially orthogonal to an underside of a hinged lid for the container. The container canister also includes a spinning disc configured with cutting teeth disposed on an axial surface thereof, the spinning disc disposed on a sidewall of the container. A ramp for directing plastics to be shredded to the spinning disc is implemented followed by the stationary disc swung into a parallel position to the spinning disc in a sandwich configuration around the plastics to be shredded. The stationary disc and the spinning disc are separated by a space configured to accommodate the respective cutting teeth thereof and a space for shards of the plastic consumer recyclable. The cutting teeth of both discs are shaped like a parrot's beak comprising a rhinotheca tomium cutting surface.

Systems and methods are provided for making aggregate from comingled waste plastics. For example, there is provided a method of making a preconditioned absorptive resin aggregate, the method including: obtaining a supply of granulated mixed plastic waste treated with a preconditioning agent that comprises at least one of calcium oxide and calcium hydroxide; mixing the supply of granulated mixed plastic waste treated with the calcium oxide preconditioning agent with one or more additives to form a plastic waste mixture, the one or more additives comprising pozzolans; hot extruding the plastic waste mixture to form an extruded product comprising waste plastic material; cooling the extruded product; and processing the extruded product to form an aggregate. Products incorporating such aggregates, such as, for example, lightweight construction blocks, are also provided. Also provided are methods of forming a waste plastics feedstock.

Disclosed are further a feeding arrangement (110) and a granulator comprising such an accumulator device (150).

A plant and method for the online recovery of trimmings generated in an extrusion line of a plastic film includes a cutting apparatus configured to cut side portions, also called trimmings, from the plastic film made leaving a forming apparatus of the plastic film; a conveying apparatus, positioned downstream of the cutting apparatus, that conveys the trimmings; an extruder for treatment of the trimmings; and an apparatus dosing and feeding granules for forming the plastic film made in the extruder, the extruder and the apparatus dosing and feeding the granules being positioned upstream of the forming device. An apparatus for pre-treatment of the trimmings is provided at the inlet of the extruder and includes a shredder positioned coaxially with respect to the extruder.

An electrostatic separation device (is for a mixture of granules of different materials. The device includes a separation chamber having an inlet and delimiting an inner volume and a collection device for granules placed in the inner volume, opposite the inlet. At least two pairs of electrodes are successively placed in the elevation direction in the inner volume, between the inlet and the collection device. Each pair includes an anode and a cathode, placed on either side of a central axis extending in the elevation direction. At least one generating system is suitable for applying a difference in electric potential between the anode and the cathode of each pair.

Generally described, the methods disclosed herein for recycling fiber composite source objects, such as wind turbine blades, include converting a whole wind turbine blade to an output material state that is useful for manufacturing other products, such as those used in construction of buildings, packaging, raw materials, and pellets, among other products. The recycling process is performed while tracking the progress and location of each wind turbine blade such that the direct source of the output material may be determined. In some embodiments, the method includes sectioning the wind turbine blades, crushing the wind turbine blade sections, tracking the progress of each blade through the process, and loading output materials into a suitable transportation vessel. Correlating each wind turbine blade to a quantity of output material provides several advantages, including various certifications of the material for uses with restricted or otherwise controlled products and materials, cost savings, and other advantages.
