***The word plastic comes from the Greek word plastikos, meaning "able to be molded."
***Thermoplastic is a material that is plastic or deformable, melts to a liquid state when heated. It can be melted and reformed numerous times.
***Thermosetting plastics (thermosets) are polymer materials that cure, through the addition of energy, to a stronger form. The curing process transforms the resin into a plastic or rubber by a cross-linking process. A thermoset plastic cannot be melted and reformed.

1. The process begins with shredding the incoming materials which breaks apart the diapers. Once the incoming materials are shredded, they are sent to a pulper.
2. The pulping action opens up the diapers. This begins the process of separating the components and exposes them for chemical treatment. Sanitizing occurs at the pulper. The plastic is removed by finger conveyors and is sent to trommels.
3. The plastics are processed in trommels, where residual fibers and waste are removed by washing. Then the plastics are then pressed and pelletized for sale to the market.

4. The pulp stream goes to coarse screening to further remove plastics which are also sent to the trommel. This stream is chemically treated to deactivate the SAP to make it possible to separate it from the fiber.
5. The deactivated SAP, along with residual small plastics, is separated from the fiber through a cleaning process. The deactivated SAP can be collected and reactivated for reuse.
6. The fibers are then put through a fine mechanical washing, cleaning and screening process. This produces a clean, marketable fiber. The reject material is sent to a sludge press.
7. The clean fiber is then pressed, baled and sold into the market. These fibers are of excellent quality as they contain very high quantity of Softwood Kraft.
8. The water extracted in the washing and thickening steps is sent to internal treatment using a dissolved air clarifier and recycled in the system as dilution water.
9. The sludge from the clarifier, as well as the fine screening and cleaning rejects, are thickened and sent to composting, for which they are well-suited and break down readily.
