The present invention relates to a multilayer, coextruded polyester film including at least one outer layer (A) and a base layer (B), in which the at least one outer layer (A) includes, to an extent of at least 60 wt %, a polyester or a copolyester formed from units derived from aliphatic dicarboxylic acids and diols, wherein the units derived from dicarboxylic acids are selected from one or more dicarboxylic acids from the group of succinic acid, adipic acid, suberic acid, azelaic acid and sebacic acid, and the units derived from diols are selected from one or more diols from the group of ethylene glycol, 1,3-propanediol, 1,4-butanediol and neopentyl glycol.

The present invention further relates to a process for producing the film according to the invention, to the use thereof and to a process for recycling the polyester film according to the invention.

Methods and systems for analysing products comprising marked materials and marking and tracking such materials are provided. A method of quantifying the proportion of a marked material comprising luminescent markers in a product comprises (i) obtaining a composite signal associated with the product, the composite signal including spectroscopic data and imaging data collected from the product, the spectroscopic and imaging data associated with a luminescent signal of the one or more luminescent markers in the marked material; (ii) identifying the marked material based on spectroscopic data associated with the one or more luminescent markers; (iii) quantifying the proportion of the marked material that is present in the product based at least in part on said imaging data of the composite signal, wherein said quantifying is based at least in part on the relative positions of and/or the number of luminescent markers detected in each image of the product.

The invention provides an apparatus for de-vulcanisation of rubber from a rubber component, preferably a rubber tire. The apparatus comprises a cleaning device configured to clean and/or sanitize the rubber and a mixing device having at least one rotor configured to de-vulcanise the cleaned and/or sanitized rubber.

The present disclosure relates to a method for preparing a wind turbine blade for recycling by sectioning the wind turbine into at least a first and a second wind turbine blade part comprising different types of materials or comprising the same type of materials in a different relative content.

The invention relates to a method for producing an EBM bottle with 0.90 to 1.5 dL/g from a bottle-grade PET post-consumer recycling flake, i.e., a recycled, post-consumer PET with a viscosity of 0.65 to 0.84 dL/g, using extrusion processes, solid state polycondensation processes, and a blowing process.

A resin is irradiated with an infrared ray, and a reflected ray from the resin irradiated with the infrared ray is received. In a reflection or absorption spectrum obtained by the reflected ray, a difference of a reflection intensity in a spectrum between a first wave number band of 1340 cm.sup.−1 to 1350 cm.sup.−1, inclusive, and a second wave number band of 1300 cm.sup.−1 to 1340 cm.sup.−1, inclusive, is calculated. It is determined whether or not a specific bromine-based flame retardant is contained in the resin, by using the calculated difference of reflection intensity in the spectrum.

A plant and a method for separating labels, caps and other contaminating materials from containers and bottles made of plastics, in particular bottles made of PET, in the field of treating and recycling plastics.

The present invention comprises a method of shredding treated medical waste, cleaning it of all traces of biological gunk, and sorting it into separate components for recycling. To clean biological gunk from materials, all materials must be first shredded into small parts to expose the interior. The cleaning is performed by submerging the gunk coated materials into a caustic solution that breaks down and dissolves the gunk off of the materials. The caustic solution may comprise sodium hydroxide, potassium hydroxide, or a similar chemical, which is highly effective in producing a corrosive chemical that can break down blood, bone marrow, urine, unused medication, food waste, organs, tissues and any other biologic materials. After all of the biological material is removed from the cleaned materials, they are sorted into component materials, such as plastics, metals, rubbers, glass, etc.

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.

Methods and equipment for the recycling of carpet are disclosed that produce a clean fiber product suitable for industrial use. The methods allow the recovery of face fiber material, for example a polyester, polyolefin, or a polyamide, from carpets that includes a face fiber material, a polypropylene backing material, and an adhesive, and include the steps of mechanically impacting the carpet to break the bonds between the adhesive and the fibrous components, treating the fibrous components to remove adhesive granules from the fibrous components, and optionally separating the polypropylene backing from the face fiber. A clean adhesive/calcium carbonate product can also be produced from this process.
