摘要： Subject of the invention is a method for recycling a glass fiber product waste to obtain recycled glass fibers. By using the waste glass mat recycling method of the invention a complete separation of the glass fibers from the binder or any other bonded precipitations is achieved. The glass fibers regained by the method are undamaged glass fibers having preserved their original geometry and mechanical performance. Surprisingly the recycled glass fibers have a surface that is very smooth, plain and wave less. A further subject of the invention is glass fiber product comprising glass fibers and at least one binder is provided, wherein the glass fibers contain at least 2% by weight of recycled glass fibers and up to 98% by weight of new glass fibers.

摘要： An apparatus for producing pozzolanic material from waste includes a glass separator unit to remove glass material from the waste and a size reduction unit downstream the glass separator unit. The glass separator unit includes an outer member and a wound member positioned within the outer member and defining an open central bore. The outer member and the open central bore define respective longitudinal axes extending on a common plane that are disposed at an angle relative to a horizontal reference plane, with the inlet higher than the outlet. Non-glass/non-ceramic material is output through the open outlet end of outer member utilizing a flow of separation fluid. The glass/ceramic material is output to the size reduction unit through the open inlet end of the outer member utilizing the rotating wound member of the glass separator unit.

摘要： A method for the alkaline digestion of soda-lime glass comprising forming a mixture of soda lime glass and a hydroxide solution, the mixture having at least 100 grams of glass per litre of H2O, the hydroxide solution having a concentration of 1M or greater to thereby form an aqueous sodium silicate fraction having a silicate concentration of 50 g/L or greater (calculated as SiO2 equivalent) and a ratio of SiO2:M2O of at least 1, wherein M2O is an alkaline metal oxide, by digesting the glass in the mixture; and separating the aqueous sodium silicate fraction from solids. The solids contain calcium silicate hydrate and undissolved glass. The calcium silicate hydrate can be CSH treated with an acid to thereby dissolve soluble metals from the CSH and separating a liquid phase from a solid phase, the solid phase comprising SiO2 or silica gel.

摘要： A process for treating a fines stream in a material recover facility (MRF), comprising: providing an MRF fines stream comprising breakable material and ductile material: subjecting the MRF fines streams to a one-pass kinetic pulverization stage to produce a pulverized material comprising a size-reduced fraction derived from the breakable material and an oversized fraction derived from the ductile material; withdrawing the pulverized material from the kinetic pulverizer; and subjecting the pulverized material to separation to produce a size-reduced stream and an oversized stream. Also provided is a system comprising a kinetic pulverizer, a pulverizer conveyor and a screen operatively coupled to the pulverizer conveyor to receive a pulverized stream and produce a sized-reduced stream and an oversized stream. The system can also include a magnetic separator and a dust collection system respectively located upstream and downstream of the kinetic pulverizer.

摘要： Methods of recovering lithium from glass include crushing the glass to produce glass particles and contacting the glass particles with an aqueous leaching solution at a leaching temperature greater than ambient temperature and less than the boiling temperature of the aqueous leaching solution to produce a leachate slurry. The glass particles include lithium. The aqueous leaching solution includes sulfuric acid in water or sodium hydroxide in water. Contacting the glass particles with the aqueous leaching solution leaches greater than or equal to about 50% of the lithium out of the glass particles. The methods further comprise separating the leachate slurry to produce a solid residue and a leachate, the leachate comprising the lithium leached from the glass particles. The method further include recovering the lithium from the leachate through precipitation.
