Aticelca 501/19

Material Performance

Mechanical separation tests form the basis of the evaluation, where the dry weight of the initial substrate undergoes disintegration in water. Analysts at the laboratory facility verify the recovery of fibers by passing the suspension through specific mesh sizes that simulate screen plate operations in a paper mill. Residue remaining on the screens represents the non-fibrous portion of the packaging, which includes laminated films, heavy wax layers, and metallic foils.

The aticelca 501/19 metric produces a percentage value indicating the total mass of accepted fibers relative to the input weight of the raw material.

Processing Impact

Converting facilities use these results to select components that permit the efficient recovery of cellulose fibers without disrupting the screen consistency of the recipient facility. An item achieving a high score under the aticelca 501/19 protocol proves compatible with existing secondary fiber systems, whereas low scores signal a need for material substitution in the design phase. Manufacturers optimize their supply chain choices by aligning the substrate composition with the limitations of current reclamation equipment.

This standard ensures that the recovery rate of fiber remains predictable across diverse waste management streams.
