摘要： The invention relates to a method for regenerating cellulose fibers from cotton-containing textile, wherein the degree of polymerization (DP) of cellulose in cotton is reduced by using a DP decreasing agent, which is an endo-cellulase of the type EC Number 3.2.1.4, together with mechanical energy. The DP of cellulose in cotton is reduced to under 1500, which makes it particularly suitable for the following steps, especially the spinning step. The cellulose is further dissolved using cellulose solvent comprising NMMO or an aqueous mixture of NMMO and the obtained cellulose-containing liquid is subjected to a spinning process to produce cellulose fibers.

摘要： A solvent that reversibly converts from a hydrophobic liquid form to hydrophilic liquid form upon contact with water and a selected trigger, e.g., contact with CO2, is described. The hydrophilic liquid form is readily converted back to the hydrophobic liquid form and water. The hydrophobic liquid is an amidine or amine. The hydrophilic liquid form comprises an amidinium salt or an ammonium salt.

摘要： A method for purifying a reclaimed polyolefin, such as a polyolefin reclaimed from post-consumer use or post-industrial use, is disclosed. The method involves obtaining the reclaimed polyolefin and contacting it at an elevated temperature and pressure with a fluid solvent to produce an extracted reclaimed polyolefin. The extracted reclaimed polyolefin is dissolved in a solvent at an elevated temperature and pressure to produce a polyolefin solution, which is purified at an elevated temperature and pressure by contacting the polyolefin solution with solid media to produce a purer polyolefin solution. A purer polyolefin is then separated from the purer polyolefin solution.

摘要： The invention refers to a method for recycling polyolefin containing waste by using a solvent with a specific Hansen parameter and contacting this mixture with a liquid filtration aid before separating the polyolefin from the mixture. The method comprises the following steps:
• Mixing the polyolefin containing waste with a solvent having a Hansen parameter δ H from 0.0 to 3.0 MPa 1/2 ;
• Contacting this mixture with a liquid filtration aid having a Hansen parameter δ H > 4.0 MPa 1/2 ; and
• Separating the polyolefin from the mixture.

摘要： There are provided recycled polystyrene polymers having a melt flow index of less than about 25 g/10 min. There are provided processes for recycling polystyrene waste. The processes can comprise dissolving said polystyrene waste in p-cymene under conditions to obtain a polystyrene/p-cymene mixture, adding the polystyrene/p-cymene mixture to a hydrocarbon polystyrene non-solvent under conditions to obtain precipitated polystyrene and washing the precipitated polystyrene with additional portions of hydrocarbon polystyrene non-solvent under conditions to obtain twice-washed polystyrene. The twice-washed polystyrene can optionally be dried and formed into polystyrene pellets. There is also provided recycled polystyrene obtained from such processes for recycling polystyrene waste.
