摘要： A system and method for producing cellulose insulation fiberizes the input cellulose material and removes cellulose dust before the resulting cellulose fibers and matrices of cellulose fibers are sprayed with a liquid fire-retardant chemical. A cellulose material metering bin supplies cellulose material to one or more fiberizers. A dryer operates to dry the liquid fire-retardant chemical to produce cellulose insulation.

摘要： A process for separation of the cellulosic part from a raw material composition comprising polyester and cellulose is provided. A blend is prepared comprising a raw material composition comprising polyester and cellulose and a hydrolyzing liquor wherein the hydrolyzing liquor comprises a first mixture comprising an alkaline solution containing hydroxide ions. The hydrolyzing liquor is added to give the blend an effective alkali concentration in a range from 5 g/l to 150 g/l, wherein the effective alkali concentration is calculated as NaOH, and the hydrolyzing liquor:raw material composition ratio is from 1.5:1 up to 25:1 and keeping the blend at a temperature of 100° C. or above.

摘要： Methods and apparatus for vacuum forming a beverage carrier yoke are described. The yoke comprises a number (e.g., four or six) collars interconnected by a web, and each collar exhibits dimensions—including a nominal diameter and a substantially uniform thickness—selected to improve strength and increase comfort. The yoke is produced using a slurry comprising a moisture barrier and a fiber base.

摘要： This specification describes a system and process for treating waste, for example municipal solid waste (MSW) or post-recycling municipal solid waste. The system includes a press and a pulper. The press is adapted to provide a wet fraction of the waste suitable for anaerobic digestion and rejects. The pulper is adapted to receive the rejects and produce pulp. The pulper may be, for example, a drum pulper. In the process, waste is separated into a press into an organic fraction and rejects. The organic fraction is treated by way of anaerobic digestion. The rejects are separated, optionally in a drum pulper, to produce a fraction containing pulp. The pulp can be re-used to make paper or other products. In some case, 70% or more or 80% or more of MSW can be diverted from landfill.

摘要： Embodiments of the invention overcome the shortcomings of prior technologies by infusing nanocellulose in a fibrillated form to enhance the properties of cellulose pulp. These properties may include, for example, the mechanical and barrier properties, i.e., tensile strength, liquid, and gas impermeability such as oxygen, carbon dioxide, and oil, can be improved substantially. Another embodiment of the invention further provide a fibrillated cellulose composite material that include properties of being a strength-enhancing agent, an oligomer, carboxylic acid, plasticizer, an antimicrobial agent, water repellant, oil repellant, and/or a transparent composite.
