Abstract: A process for molding recyclable, compostable, and disposable containers made of pulp paper is disclosed herein. The process includes disposing a wet pulp layer on a male or female mold, mating the mold with its counterpart, and applying a force on the pulp layer to remove moisture and thin the pulp. The process continues by applying a vacuum to either the male or female mold to hold the pulp layer, and removing the other mold. The process further comprises sequentially mating male and female molds until the pulp layer is the desired thickness and shape of the container. Embodiments of the process may include molding pulp containers to include pleats, stability features, reverse draft features, and puffed pulp configurations.

Abstract: Methods for making a molded beverage container insulator from a slurry including water and a polysaccharide by presenting at least one male mold, which may have an elliptical cross section, therein and causing a portion of the slurry to temporarily adhere to the at least one mold. After a suitable period of time, removing the mold from the slurry and then removing the insulator. At such time, and particularly if the mold is not characterized as elliptical in cross section, the insulator is subject to bidirectional compression in order to collapse the same. Opposing hinge elements may be formed in the insulator, either at the time of molding or subsequently, to localize stresses resulting from the collapsing of the insulator. The resulting insulator is fully recyclable/compostable and possesses a constricting bias to mitigate container slip issues.

Abstract: In one embodiment, a shredder maintenance material delivery system includes a leader and a containment vessel. The containment can be configured to carry a maintenance material and configured to apply the maintenance material to at least on shredder component when the shredder maintenance material delivery system is shredded.
