A super anti-slip composite carpet with a three-dimensional TPE elastic structure, which is formed by compounding a fabric layer (1) and a TPE layer (2), wherein TPE is composed of 80-90% of styrene oxide-butadiene block copolymer and 10-20% of polypropylene, and the TPE layer (2) has a thickness of 1-2 mm. The compounding process thereof includes: step 1, preheating a transparent TPE to 80° C., and adding to a material barrel of a casting machine, stirring the TPE by a screw, and heating to a heating temperature of 140° C.-200° C. in 6-9 sections, to obtain a paste-like TPE; step 2, extruding the paste-like TPE through a metal joining pipe into a die head; step 3, making the paste-like TPE flow out through the die head in a planar cascade shape, and at the same time, passing the paste-like TPE flowed out from the die head together with a back part of a carpet fabric through a gap between an embossed roller and a rubber roller, so as to compound with the bottom surface of the fabric layer. The carpet has a good anti-slip effect and no edge warping, and is light resistant, aging resistant, non-toxic and tasteless, safe and reliable.

In particular embodiments, a process for producing bulked continuous carpet filament from recycled polymer utilizes two vacuum pumps (140A, 140B) in combination with a single extruder (100). In various embodiments, the dual vacuum arrangement (e.g., at least two vacuum pumps (140A, 140B)) operably coupled to the single extruder (e.g., MRS extruder (100)) may be configured to remove one or more impurities from recycled polymer as the recycled polymer passes through the extruder.

A composite ash produced by thermally processing paper and/or carpet exothermic processing waste, the composite ash being an inorganic mineral product or oxidized material of common crystalline and amorphous non-crystalline composition comprising metakaolin and at least one of a group consisting of mineral oxide and mineral carbonate, the composite ash being reactive with a pH greater than about 7.0.

A system for and method of, processing post-consumer and post-industrial waste streams, producing active ingredients for waste stream processing, processing aqueous waste streams, preparing and collecting a multi-purpose chemical precursor, removing phosphates, nitrates, heavy metals, and other contaminants from aqueous waste streams, collecting and processing a post-consumer and post-industrial product from aqueous waste streams, administering and positioning assets and processes associated with waste stream processing, and scheduling operations for sub-systems of the system.

A composite material is produced from carpet waste and a binding agent, in intimate association, and may also include wood fiber or chips and/or other additives. A method of manufacturing a composite material includes shredding carpet waste, coating the carpet waste with a binding agent, and subjecting the shredded, coated carpet waste to elevated heat and pressure. As an additional step, the composite material may be actively cooled to prevent deformation of the material.

Fossil-fuel and rubber-derived waste stream conversion to composite lumber substitutes or barrier members; the composites having material properties and uses of greater value than the solid waste stream components separately or together. Preferred combinations including waste materials derived from waste carpet, waste tires, and waste bituminous roofing shingles, all enormous problems for landfill disposal. In a range of formulation ratios, when combined with a binder, new and marketable products are made from solid waste. Improved resistance to rot, to water, and to weathering is exhibited in synergy with improved compressive and flexural strength, enabling production of a wide variety of useful and environmentally-friendly structural products, for example. Product weight and strength can be engineered to suit and may be structural members for architectural, engineering or agricultural use. Advantageously, the new products themselves can be re-used—by an end-of-life process for making more new products, achieving the capacity to make and remake multigenerational products from solid wastes and to reduce loading of landfills.

Systems and methods are provided for fabricating and utilizing segmented hollow fibers. One embodiment is a method for fabricating a hollow fiber. The method includes disposing injection needles at orifices of a die, loading the die with a pool of molten material, driving the molten material through the orifices of the die, and iteratively injecting a gas into the molten material at the orifices via the injection needles and pausing injecting the gas as the molten material is driven through the orifices of the die, resulting in discrete hollow chambers within molten material exiting the die. The method also includes cooling the molten material into a hollow fiber that includes the discrete hollow chambers.
