A method for producing environmentally friendly, mono-extruded hemp composite board (EHB) is provided. By using hemp fiber and hemp hurd in combination with virgin and/or recycled binders, the system and method may be used to create preferable substitutes for traditional construction boards. The method generally comprises steps of processing hemp hurd/fiber and injecting said hemp hurd/fiber into an extruder along with a binder. Waste products from other production streams may be added as well to reduce waste/cost of said production streams. The resulting EHB is structurally superior to traditional construction boards largely due to the structural characteristics of dispersed hemp hurd and hemp fiber, their complete encapsulation in a binder material, and their lower hygroscopic properties. Additionally, since the EHB is created using an extruder, a downstream extrusion arrangement may be used to mold the EHB into shapes that are difficult to achieve with traditional construction boards.

A process that removes chlorine or other halogens from plastic mixtures by passing a plastic mixture through an extruder, a mixer, and one or more devolatilization vessels.

A method of making a lightweight foamed recycled leather, the method includes pulverizing the collagen fiber waste generated in a controlling a thickness of the leather during a leather process; neutralizing the resultant of step (a) by a soda ash with a water; (c) dyeing and fat-liquoring process treating the resultant of the step (c); (d) mixing a latex, a dispersant, a coagulant, and a thermally expandable microspheres with the resultant of step (c); (e) coagulating a collagen fiber powder and the latex by adding a coagulant into the resultant of step (d); (f) dehydrating and drying the resultant of step (e); and (g) heat treating the resultant of step (f) to foam thermally expandable microspheres, thereby to impart functionality to the recycled leather.

Presented are manufacturing systems, methods, and devices for forming footwear using scrap or waste plastic materials. A method for manufacturing an article of footwear, such as an athletic shoe, begins with receiving a batch of recycled plastic, which may include thermoplastic elastomers or ethylene-vinyl acetate, and grinding the batch of recycled plastic material. The ground recycled material is processed, for example, by adding a foaming agent that activates at elevated temperatures. The processed recycled material is placed into the internal cavity of a final mold that is shaped like a segment of the footwear, such as a unitary sole structure. To form the footwear segment, the processed recycled material is heated past the threshold activation temperature of the foaming agent such that the foaming agent causes the recycled material to expand and fill the internal cavity of the final mold. The formed footwear segment is then extracted from the mold.

A polyester film constituted of a polyester resin which has an intrinsic viscosity (IV value) of 0.640-0.700, wherein the polyester resin constituting the polyester film contains a P element and further contains at least one element selected from among Mn, Mg, Ca, K, and Na elements, and when the content of the P element in the whole polyester resin is expressed by P (mol/t) and the total content of the Mn, Mg, Ca, K, and Na elements is expressed by M (mol/t), then the following relationships (1) and (2) are satisfied:
