Pupunha-reinforced polypropylene composite
Methods and systems are provided for a composite material. In one example, the composite material includes a polymer base reinforced with a powder formed from pupunha fibers. The resulting composite material is provided as pellets for further processing.
Method for dissolving lignocellulosic biomass
A method of dissolving lignocellulosic biomass waste includes obtaining raw lignocellulosic biomass waste, reducing a size of the biomass waste to provide a biomass particle size of less than about 200 μm; using dimethyl sulfoxide (DMSO), sodium hydroxide (NaOH) and trifluoroacetic acid (TFA) solvents to dissolve the biomass particles and achieve a dissolved lignocellulose solution. The present method dissolves at least about 94% of the lignocellulose fraction in the waste biomass. In an embodiment, the biomass particle size can be about 180 μm.
Laminate
A laminate, containing two or more polyolefin resin layers, wherein at least one polyolefin resin layer (A) contains a cellulose fiber including a cellulose fiber having a fiber length of 0.3 mm or more dispersed in the layer; a content of the cellulose fiber in the polyolefin resin layer (A) is 1% by mass or more and less than 60% by mass; and wherein a polyolefin resin layer (B) different from the polyolefin resin layer (A) is laminated in contact with the polyolefin resin layer (A).
Biodegradable and Industrially Compostable Injection Molded Microcellular Flexible Foams, and a Method of Manufacturing the Same
A process for injection molded microcellular foaming various flexible foam compositions from biodegradable and industrially compostable bio-derived thermoplastic resins for use in, for example, footwear components, seating components, protective gear components, and watersport accessories wherein a process of manufacturing includes the steps of: producing a suitable thermoplastic biopolymer or biopolymer blend; injection molding the thermoplastic biopolymer or biopolymer blend into a suitable mold shape with inert nitrogen gas; controlling the polymer melt, pressure, temperature, and time such that a desirable flexible foam is formed; and utilizing gas counterpressure in the injection molding process to ensure the optimal foam structure with the least amount of cosmetic defects and little to no plastic skin on the outside of the foamed structure.
Injection-molded composite construct
A frame is injection molded onto a group of panels to form a container. The panels extend at least partially around, and at least partially define, a cavity of the container.
System and method for reprocessing animal bedding
A method and system reprocess soiled animal bedding material commingled with animal manure. In one aspect the soiled animal bedding material is separated in a shaker to send at least a preponderance of the manure to a holding tank. In another aspect the bedding is cleaned, rinsed and color is restored. The bedding material is subsequently dried and a bedding product, fertilizer product, and/or compacted product is formed. Alternatively, the bedding material is dried (without a compacting step) to form a product. In yet another aspect, the steps of separation, cleaning, rinsing and/or color restoration may be omitted.
Cellulose-fiber-dispersing polyolefin resin composite material, pellet and formed body using same, and production method for cellulose-fiber-dispersing polyolefin resin composite material
A cellulose-fiber-dispersing polyolefin resin composite material, containing a polyolefin resin containing a polypropylene resin, and a cellulose fiber dispersed in the polyolefin resin, in which a proportion of the cellulose fiber is 1 mass part or more and 70 mass parts or less in a total content of 100 mass parts of the polyolefin resin and the cellulose fiber, and the water absorption ratio satisfies the following Formula: (Water absorption ratio [%])<(Cellulose effective mass ratio [%]).sup.2×0.01; a pellet and a formed body using this composite material; and a production method for this composite material.
TEXTILE RECYCLING
A textile recycling method receives textile-waste-to-be-recycled, sorts the waste to isolate cellulose-containing articles from non-cellulose-containing articles, and re-sizes at least some of the cellulose-containing articles to create feedstock. The feedstock is processed in a cellulose solvent reactor, which has at least one ionic liquid. The ionic liquid dissolves intermolecular cellulose bonds of the feedstock to create a spinning dope. Cellulose fibers dissolved in the cellulose-bearing spinning dope solution are extruded in a cellulose coagulation bath reservoir to reconstitute at least some of the cellulose fibers, and the reconstituted fibers are wet-spun to form a continuous cellulose thread that is commercially indistinguishable from virgin fiber thread. Synthetic fiber material is vacuum-extracted or mechanically extracted from the cellulose-bearing solution and recycled into a continuous synthetic thread. Original color of textile-waste-to-be-recycled can be retained or removed, and new color can be added.
Method for casting an alkaloid material including changing a height of a casting blade in response to variations in sensed movable support height
The invention relates to a method to cast a sheet (2) of a material containing alkaloids, the method comprising: Providing a container (6) having an aperture; providing a casting blade (9); Providing a movable support (3) running below the aperture of the container (6); Filling the container (6) with slurry (5); Casting the sheet (2) of tobacco material containing alkaloids material by means of the casting blade (9) onto the movable support (3); Sensing variations in a height of the movable support (3); and changing a height of the casting blade (9) if such variations in the height of the movable support (3) are present.
Cellulose based film structure and method for producing the same
According to an example aspect of the present invention, there is provided a cost-effective method of producing cellulose based films by introducing an intense water removal system to the process, and cellulose based films thereof having improved properties.
