Patent number: 10376897Abstract: Methods for the recycling of carpet are disclosed that produce clean face fiber suitable for industrial use. The methods allow the recovery of face fiber material, for example a polyester or a polyamide, from carpets that includes a face fiber material and a backing material, and include the steps of heating the carpet to a temperature lower than the melting point of the face fiber material, but higher than the initial thermal decomposition temperature of the backing material, for a time and at a temperature sufficient to thermally decompose, pyrolyze, or oxidize at least a portion of the backing material, rendering the backing material friable, that is more friable than the untreated backing; and applying mechanical force to the carpet so as to liberate the friable backing material from the face fiber material.Type: GrantFiled: August 4, 2017Date of Patent: August 13, 2019Assignee: Shaw Indusries Group, Inc.Inventors: Joseph E. Bork, Stephen C. Paspek, Sr., Alan F. Schroeder, William H. Heise

Publication number: 20090095660Abstract: A process is described for the separation of fluorinated plastic particles from a mixture of solid particles of similar specific gravity. The process comprises mixing the particles with water, adding air to create bubbles, and generating two or more product streams, one of which floats and the other which sinks. The floating stream is enriched in fluoropolymer particles. Per pass yield and selectivity of fluorinated plastics are enhanced by the addition of a carboxylic acid to the froth flotation medium.Type: ApplicationFiled: October 13, 2008Publication date: April 16, 2009Applicant: BROADVIEW GROUP, LLCInventors: Stephen C. Paspek, JR., Joseph E. Bork, Alan Schroeder, Christopher Kulbago

Publication number: 20090065404Abstract: A process for the separation of a multiple domain solid feedstock such as that derived from ASR, WSR, and/or ESR is disclosed which comprises granulating the feedstock to produce particles each of substantially a single domain, with each type of particle having a different density. The particles are introduced into a suitable aqueous salt solution. Aqueous salt solutions containing cations comprising sodium, calcium and ammonium, and anions comprising nitrate, bromide, and chloride are useful. A dispersion mixer having a high shear and/or turbulent zone is utilized to disperse agglomerated particles and a quiescent hydrogravity tank is utilized to effect binary separation of the mixture of particles into a stream with a higher average specific gravity, and a stream with a lower average specific gravity. A higher degree of product purity can be obtained by subjecting either of the product streams from the first hydrogravity stage to additional stages of hydrogravity separation.Type: ApplicationFiled: November 5, 2008Publication date: March 12, 2009Applicant: PASPEK CONSULTING LLCInventors: Stephen C. Paspek, JR., Joseph E. Bork, Alan Schroeder

Patent number: 7497335Abstract: Hydrogravity separation of a multiple domain solid feedstock is disclosed which comprises granulating the feedstock to produce particles each of substantially a single domain, with each type of particle having a different density. The particles are slurried into a suitable fluid. A dispersion mixer having a high shear and/or turbulent zone is utilized to disperse agglomerated particles and a quiescent hydrogravity tank is utilized to effect binary separation of the mixture of particles into a stream with a higher average specific gravity, and a stream with a lower average specific gravity. A high degree of product purity is obtained by feeding one or both of the initial product streams to a collection of dispersion mixer/hydrogravity tank units using a fluid of substantially the same specific gravity.Type: GrantFiled: December 12, 2005Date of Patent: March 3, 2009Assignee: Broadview Group LLCInventors: Joseph E.
