Bio-based aerogel beads for drought mitigation in soil
Introducing biodegradable aerogel beads made from cellulose and chitosan to enhance soil moisture retention and nutrient delivery, improving drought resistance in plants. Ideal for residential lawns and gardens, they reduce water use and support plant health.
Overview
Bio-based aerogel beads offer a revolutionary solution for enhancing drought resilience in residential lawns and gardens. These biodegradable beads, made from nanofibrillated cellulose (NFC) and chitosan, act as a smart soil additive. They absorb water during rainfall and irrigation, releasing it slowly to maintain root-zone moisture, thereby supporting plant survival during droughts and reducing overall water usage. Additionally, they deliver nutrients and biostimulants, promoting healthy root systems and a thriving soil microbiome.
Technical specifications
The aerogel beads are manufactured through alkaline gelation of NFC and chitosan, followed by freeze-drying, resulting in a robust and porous 3D structure. Key features include:
- High water absorption: Beads can absorb 8–13.5 times their dry weight in water.
- pH-responsive nutrient release: Chitosan enables controlled release of NPK nutrients.
- Biostimulant enhancement: Post-loaded with algae to supply micronutrients and amino acids.
- Environmentally friendly: Biodegradable and enhances soil health.
Technology readiness level
Currently at TRL 4, the technology has undergone initial validation and plans are in place for further development. Upcoming phases include greenhouse trials, field validation, and scale-up efforts, aiming for regulatory certification and commercial readiness.
About University of Georgia
The University of Georgia is a comprehensive public land‑grant research university serving a large student body across multiple campuses, known for applied scholarship and community partnership. Industry partners access core facilities and pilot‑scale capabilities—including the Food Product Innovation and Commercialization Center—for prototyping, scale‑up, and product validation. A downtown Innovation District and a statewide Cooperative Extension network link campus expertise to companies across Georgia, while proximity to Atlanta’s corporate and logistics hubs lowers barriers to engagement. Research is supported by competitive federal funding from agencies such as NIH, NSF, USDA, and DOE. A dedicated technology transfer office provides IP services, licensing, startup support, and incubator space to accelerate commercialization.
