摘要： An apparatus for processing waste plastic material is provided, the apparatus comprising: a comminution assembly comprising: a comminutor comprising: an inlet for plastic material to be comminuted; an outlet for comminuted plastic material; and a blade assembly comprising a plurality of blades; and a washing assembly comprising: a washing vessel having an inlet for comminuted material and an outlet for washed material; and an agitator for agitating the contents of the washing vessel. A method for processing waste plastic material comprises (i) comminuting the waste plastic material in a comminutor having an inlet for waste plastic material and a blade assembly comprising a plurality of blades, to produce a comminuted plastic material; (ii) subjecting the comminuted plastic material to a wash comprising mixing the comminuted plastic material in water to form a suspension and subjecting the suspension to agitation to produce a washed comminuted plastic material; and (iii) separating the washed comminuted plastic material from the water. The apparatus and method are particularly suitable for the processing of waste or used fishing nets.

摘要： A method of recovering poly(vinyl butyral) (PVB). The method comprises a step of providing a solvent to a reclamation system. An additional step includes adding a recycled PVB to the solvent and stirring at a certain temperature for a specified time to dissolve the recycled PVB and form a PVB mixture. An additional step includes filtering the PVB mixture to remove the PVB solids. A further step includes subjecting the PVB solids obtained from the PVB mixture to heat obtain recovered PVB polymer.

摘要： An integrated, automated process for separating and recycling a broad mix of plastic waste material including, without limitation, polyester and polyolefin streams. The process begins by collecting the material. The material is then pre-processed to remove contamination. Next, the material is coarsely shredded, resulting in ground material. The ground material is friction washed to remove further contaminants from the ground material and form cleaned ground material. The cleaned ground material is sink floated to further wash the clean ground material and separate it into polyolefin flakes and polyester remainder. The polyester remainder is dried, yielding polyester flakes. Finally, the polyester flakes are collected. The process eliminates the tradeoffs between recovery and purity that perplex recycling facilities and permits simultaneous handling of polyesters and polyolefins. Also provided are a related center (and an infrastructure including the center) and at least one computer-readable non-transitory storage medium embodying software for performing the process.
