摘要： The present invention relates to a process for obtaining a dialkyl phthalate and a reusable target PVC plastic from a PVC feedstock containing at least one phthalate, including:
a) solid-liquid extraction of PVC feedstock in the form of particles by placing the particles in contact with a solvent to produce a liquid phase enriched in the phthalate and a solid phase including PVC plastic depleted in the phthalate;
b) transformation of the phthalate of the liquid phase into dialkyl phthalate by transesterification using the solvent;
c) a solid-liquid separation between the solid phase and the liquid phase to produce at least one solid stream including the PVC plastic depleted in the phthalate so as to obtain the target PVC plastic;
d) a liquid-liquid separation of the liquid phase, to produce at least a first liquid effluent including the dialkyl phthalate and a second liquid effluent comprising said solvent.-

摘要： A composite material is formed by preparing mass particles consisting of a fibrous material at least partially derived from recycled post-consumer materials and preparing particles of a binding material consisting of a thermoplastic material at least partially derived from recycled post-consumer material. The prepared mass particles and particles of binding material are mixed together such that the binding material liquifies and coats the mass particles which are subsequently then pressed together to form a composite article in which the mass particles typically occupy between 35% and 60% by weight of the composite material and the binding material occupies between 40% and 60% by weight of the composite material. The composite material is suitable for replacing concrete, wood, or other construction, manufacturing or industrial materials, and possesses properties that in some applications may be equal or superior such materials.

摘要： Microorganisms capable of effectively decompose hardly decomposable thermoplastic polyurethane, a method for decomposing thermoplastic polyurethane, and a method for selecting microorganisms capable of decomposing thermoplastic polyurethane are provided.
The method for selecting microorganisms capable of decomposing thermoplastic polyurethane includes a step of burying in soil a mixed sample of thermoplastic polyurethane having urea bond and polyurethane without urea bond and a step of collecting the microorganism adsorbing to the mixed sample after confirming the urethane decomposition by infrared spectroscopic analysis of the buried mixed sample.-

摘要： A method of manufacturing bulked continuous carpet filament from recycled polymer. In various embodiments, the method includes: (1) reducing recycled polymer material into polymer flakes; (2) cleansing the polymer flakes; (3) melting the flakes into a polymer melt; (4) removing water and contaminants from the polymer melt by dividing the polymer melt into a plurality of polymer streams and exposing those streams to pressures below 5 millibars; (5) recombining the streams; and (6) using the resulting purified polymer to produce bulked continuous carpet filament.
