Not relevant to microplastics — this study develops biodegradable hydrogels from fruit waste (pectin and starch) to reduce water loss and slow herbicide migration in sandy agricultural soils, without any connection to plastic pollution.
Structurally engineered cellulose-based mulch film with enhanced hydrophobicity and strength for green agriculture
This paper develops a cellulose-based mulch film coated with starch and a silane compound to mimic the strength and water resistance of conventional plastic agricultural film, achieving a water contact angle of 128 degrees (up from 16 degrees for untreated cellulose) and complete biodegradation in soil within 56 days. Unlike polyethylene mulch films that fragment into persistent microplastics in farmland, this material decomposes within a crop growing cycle, offering a practical biodegradable alternative for agriculture.

Not relevant to microplastics — this paper develops and tests bio-based superabsorbent gels made from carboxymethyl cellulose as sustainable alternatives to petroleum-based superabsorbent polymers for water retention applications.
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.
Development of bio-based, biodegradable geotextiles for the revegetation of stabilized landslide-prone areas
Researchers developed bio-based, biodegradable geotextile materials from natural fibers for revegetating landslide-prone slopes as an alternative to synthetic plastic geotextiles. The natural fiber materials supported plant growth and degraded over time without leaving persistent plastic in the soil. Replacing synthetic geotextiles with biodegradable alternatives could reduce microplastic contamination of soil and nearby waterways.
