The keywords focus on the degradation and recycling of crosslinked polyacrylic acid structures. Solving the persistence of these materials allows for the recovery of raw materials and reduces environmental impact.

The persistence of non-biodegradable superabsorbent polymers in the waste stream creates environmental disposal challenges. Enabling chemical breakdown allows for material recovery and circularity in absorbent products.

The keywords focus on the enzymatic degradation and sterilization of post-consumer hygiene products. The core problem is the physical persistence and bulk of used absorbent materials which prevents efficient disposal or recycling.
