摘要:
The invention relates to a method comprising mechanically treating a lignocellulosic or cellulosic material and passing the mechanically treated material through a first screen having an opening size of 3.175 mm (1/8 inch) or less, to provide a screened fibrous material, and combining the screened fibrous material with a biodegradable polymer.
摘要:
A separation device having high separation efficiency and a method for manufacturing a water absorption material using the separation device are provided. A separation device (1) includes a shredding unit (10), and a separation unit (20). The shredding unit (10) shreds a disposable diaper (processing target) containing a plastic (first material) and a water-absorbent polymer (second material) adhering to the plastic. The separation unit (20) has a drum (22), and a beating member (24). The separation unit (20) separates the water-absorbent polymer passing through the holes (22a) from the disposable diaper by beating the disposable diaper with a plate surface of the beating member (24) with the drum (22) being rotated in a state in which the disposable diaper shredded by the shredding unit (10) is accommodated in the drum (22).
摘要:
Method for recovering plastic from complex materials; comprising, at least, the following steps: successive grindings of the complex product into granules of 8 to 12 millimetres, 4 to 6 millimetres and a size equal to or less than 2 millimetres, performing, after each grinding, the separation of the polyester fluff from the remaining mixture of plastic with polyester, finally subjecting the remaining mixture to successive agitations and removals of the polyester fluff by sifting, aspiration, blowing and/or propulsion, until plastic with a purity of 99.99% is obtained.
摘要:
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. In particular, a method of densifying a fibrous composition is disclosed, the method comprising: shearing a fiber source to provide a fibrous material; combining the fibrous material with a microorganism and/or enzyme to provide a fibrous material composition; encapsulating the composition in a substantially gas impermeable material; and removing entrapped gas from the encapsulated composition to densify the composition.
