Embodiments relate to a polyester-based film and a process for regenerating a polyester-based container using the same, which not only solve the environmental problems by enhancing the recyclability of polyester-based containers but also are capable of enhancing the quality, yield, and productivity. When the polyester-based film is cut into a size of 1 cm in width and 1 cm in length, immersed in an aqueous solution of sodium hydroxide (NaOH) having a concentration of 1% by weight, and stirred for 15 minutes at 85° C. at a speed of 240 m/minute, the average particle size of the component of the printing layer separated from the base layer satisfies 15 μm or more. Thus, it is possible to enhance the quality of the regenerated polyester-based chips produced from the polyester-based container provided with the polyester-based film.

A polyester film and a method for producing the same are provided. The polyester film includes a physically recycled polyester resin and a chemically recycled polyester resin.

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 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 having a rhinotheca tomium cutting surface.

The invention relates to a mechanochemical process for decontaminating and/or for eliminating problematic, synthetic, biogenic and biological materials A; for breaking down phosphates B; for immobilising metals and the compounds C thereof; for separating carbon dioxide and carbon monoxide D into elements; and for recovering valuable products E. The process comprises: —providing a material F to be milled containing —at least one material A, B, C and/or D and —at least one type of carbon or carbon-yielding material G, or alternatively providing the components of F and G separately from one another; —filling the material F to be milled into a mechanical mill (1), or alternatively —filling the components of the material F to be milled into a mechanical mill (1) and —milling by means of milling elements (1.2) moved by agitation means (1.4) or by means of rollers (1.4.6); after which —the resulting product I is separated from the milling elements (1.2) or the rollers (1.4.6) and is discharged from the milling chamber (1.1) and worked up. The invention also relates to the use of the products I as valuable materials E, the use of a self-cooling electric motor (4) for driving a mechanochemical mill (1), and mechanochemical mills (1) having new agitation means (1.4).

In a method for reprocessing film waste material, the film waste material is comminuted into recycling material by means of a comminuting device. The recycling material is fed by means of a feeding device in a multi-shaft screw machine. In the multi-shaft screw machine, the recycling material is plasticized into a material melt and processed into raw material. The raw material may again be fed to a production installation for the production of films.
