About PackRethink — engineering for high-quality recycling

Founded by material scientists and packaging engineers, PackRethink addresses the most persistent barriers to high-quality packaging recycling. Laminates, adhesives, and contamination historically reduce the usefulness of recovered materials. Our core competency is in adaptive separation techniques that match the incoming stream composition: hybrid disc screens and air classifiers for film-fibre separation, friction-based cleaning for coated surfaces, and targeted delamination modules that recover usable fibre fractions without excessive mechanical shear.

In the laboratory we quantify damage mechanisms—fibre shortening, polymer chain scission and contamination enthalpy—then translate those findings into plant-level process control settings. This results in reclaimed cellulose with reproducible drainage and tensile properties, polymer concentrates with predictable melt-flow behaviors and composite fractions that can be blended into new products with known performance envelopes. Brand partners receive a full analytics pack including proximate composition, residual moisture, contaminant spectra and suggested blend ratios for downstream converters.

PackRethink also invests in product redesign workshops. By collaborating with design teams early in the product lifecycle we recommend structural simplifications, mono-material strategies, and adhesive systems that are compatible with mechanical recycling, enabling easier reclamation and higher final recycled content in new packaging.
