Provided is a polymer composition for manufacturing a large container that contains high-density polyethylene recycled from a secondary battery separator and has excellent mechanical properties. Specifically, a polymer composition having excellent processability may be prepared by recycling a secondary battery separator, and an eco-friendly large container having excellent mechanical properties such as a flexural modulus, an elongation, and an impact strength in a wide temperature range, and having an excellent environmental stress cracking resistance may be manufactured by molding the polymer composition.

An improved composite paver is provided specifically designed to overcome the limitations of conventional concrete pavers. The paver comprises a base layer made from a mixture of concrete and epoxy in an eight-to-two ratio by volume, providing enhanced durability and resistance to cracking. An appearance layer, consisting of colorful vinyl flakes, is applied atop the base layer, adding texture and visual appeal. The paver is further encapsulated with an additional layer of epoxy mixed with clear sand, offering slip resistance and protection against environmental factors. The unique combination of materials and the manufacturing process results in a paver that is not only aesthetically pleasing but also significantly more durable and low maintenance compared to traditional options. The composite paver is suitable for various applications, including outdoor spaces such as patios, driveways, and walkways, providing a long-lasting and visually attractive paving solution.

Fibrous materials, compositions that include fibrous materials, and uses of the fibrous materials and compositions are disclosed. For example, the fibrous materials can be operated on by a microorganism to produce ethanol or a by-product, such as a protein or lignin.

A recycled fiberglass reinforced polymer composite article and a method of the same are disclosed in the present disclosure. The reinforced composite article is composed of a recycled fiberglass collected from waste streams and functioning as a filler, the recycled fiberglass being 30-70% of a total weight of the reinforced composite article; a colorant of 1-2% of the total weight of the reinforced composite article; and a recycled resin substantially wetting-out the recycled glass fiber by the black colorant and a chemical binder.

A method of producing an exercise weight structure comprises mixing a particulate material with a binder material and molding the resulting mixture to an appropriate shape. An outer skin for the exercise weight structure is firstly formed of a resilient material, and forms a mold into which an inner weight section or body is molded or cast. The inner weight section and the outer skin are both formed of recycled material and include a common binder material.

A method of forming end-form structures from recycled plastics includes i) providing molten agglomerated plastics in noodle form; ii) delivering the molten agglomerated plastics to a shaper; iii) forming an end-form of agglomerated plastics in the shaper by controlling movement and/or position of the shaper, the end-form comprising the agglomerated plastics welded together with voids therebetween; and iv) cooling at least an outer profile of the end-form to form the structure.

A method for recycling prepreg materials including the steps of: a) providing at least one prepreg material including a first thermosetting polymer resin, partially crosslinked, and a weave including fibers, b) applying a vitrimerization reaction mixture to the at least one prepreg material, c) placing the at least one prepreg material coated with the vitrimerization reaction mixture on a mold of a predefined shape, d) applying a thermocompression to the at least one prepreg material at a temperature (T1) greater than or equal to the glass transition temperature (Tg) of the first resin, so as to activate the reaction between the vitrimerization reaction mixture and the thermosetting polymer leading to the formation of a vitrimer polymer and the transformation of the at least one prepreg material into a vitrimer composite material of the predefined shape.

In accordance with embodiments of the present disclosure, a method for forming a layered composite structural member may include reducing post-consumable material in size into smaller particles, forming the smaller particles into a core layer of material, and coupling the core layer of material to at least one layer of laminate material.

A stretch blow-molded article comprising: a first polyester; and a second polyester having a structure different from a structure of the first polyester, wherein an intrinsic viscosity value of the first polyester is 0.60 to 0.74 dL/g, and the second polyester has a structure corresponding to terephthalic acid and a structure corresponding to bisphenol A.

A method is provided in which suitable carbon-fiber scrap is fed, together with a plastic polymer, to a pulverizer and extruder in order to produce a carbon-fiber polymer mass therefrom and to impregnate the mass with a resin. A regrind prepreg, which is given suitable forms and/or lengths, is thus obtained. The regrind prepregs thus obtained can then be given an approximately final form in an additional step by way of an extrusion process.
