Superabsorbent Hydrogels in the Agriculture and Reclamation of Degraded Areas
This review examines superabsorbent hydrogels, polymer materials that can absorb hundreds of times their weight in water, and their use in agriculture and land restoration. Researchers found that while these materials can significantly improve soil water retention and crop yields, concerns remain about chemical leaching and potential microplastic generation as they degrade. The study suggests that more research is needed on the long-term environmental safety of synthetic hydrogels in soil.
Cellulose-Based Aerogels for Environmentally Sustainable Applications: A Review of the Production, Modification, and Sorption of Environmental Contaminants
This review explores how aerogels made from cellulose, a natural plant-based material, can be used to filter pollutants including microplastics from water and soil. While cellulose aerogels are promising because they are biodegradable and come from renewable sources, they need chemical modifications to work effectively in water treatment applications.

Cellulose-Based Materials as a Sustainable Alternative to Plastics: Mitigating Environmental Pollution Through Biodegradability and Reduced Toxicity
This research review shows that materials made from cellulose (the stuff in plant cell walls) could replace regular plastics and help protect human health. Unlike regular plastics that break down into tiny harmful pieces called microplastics that get into our food and water, cellulose materials naturally break down into safe, non-toxic compounds. Making the switch could reduce the plastic pollution that's contaminating our environment and potentially harming our health.
