Recyclability Assessment
Fibre recovery performance quantifies the capacity of paper products to release cellulose fibres during standard hydrapulping operations. Cepi repulpability determines the percentage of mass remaining on a screen after the slurry undergoes mechanical agitation and filtration. This method assesses if the board or paper stock remains compatible with conventional mill infrastructure or requires specialized chemical treatment for effective separation.
Industrial Threshold
Sorting facilities rely on these results to verify whether specific coatings or synthetic adhesives obstruct the standard cleaning circuit. Cepi repulpability acts as a quality gate for producers who introduce non-fibre elements into their substrates. A result exceeding the established screen residue limit indicates the material creates excessive waste or rejects within the mill system.
Process engineers use the data to validate that additives do not trap long fibres in the sludge stage.
Material Constraint
Cellulose yield drops when functional layers or wet strength resins resist disintegration during the initial cycle. Cepi repulpability sets the technical boundary for circularity in fibre packaging by identifying exactly how much material enters the finished paper stream versus how much moves to landfill or incineration. High scores demonstrate that the product maintains high material utility throughout the recovery phase.
