Biodegradable cellulose microsphere for controlled release of micronutrients
Naturbeads offers a sustainable solution for agriculture with its biodegradable cellulose microspheres designed for the controlled release of micronutrients, enhancing plant growth while minimizing environmental impact.
Overview
Naturbeads has developed an innovative solution for the agricultural industry with its biodegradable cellulose microspheres. These microspheres, ranging from 10 to 1,000 micrometers, are designed to adsorb and gradually release micronutrients essential for plant growth. This controlled release mechanism not only optimizes nutrient uptake by plants but also ensures that no residue is left behind, as the cellulose fully degrades over time. This technology stands out due to its environmentally friendly nature, offering a sustainable alternative to traditional fertilizers.
Technical specifications
Key features:
- Biodegradable material: 100% cellulose microspheres ensure complete degradation without environmental harm.
- Controlled release: Unique hydrogel formation allows for high nutrient adsorption and gradual release over time.
- Versatile application: Effective for a range of micronutrients, demonstrated in various conditions.
- Manufacturing readiness: The process is at TRL8 with the first manufacturing plant operational.
Technology readiness level
The biodegradable cellulose microsphere technology is at TRL5 for nutrient uptake and release processes. It has been validated in relevant conditions, with ongoing trials and feasibility studies to optimize and scale up the process further. The first phase of controlled trials is planned to refine the nutrient release mechanisms, with collaborative opportunities available for further development.
About Naturbeads
Naturbeads is a sustainable materials startup that specializes in producing biodegradable cellulose-based microspheres to replace harmful microplastics. The company utilizes a patented, continuous, and closed-loop manufacturing process that transforms cellulose—derived from natural sources like trees—into perfectly spherical, uniform particles. By using a unique green-solvent system and membrane emulsification, Naturbeads can precisely control particle characteristics such as size, porosity, and surface texture without altering the chemical structure of the cellulose. This innovative technology allows for the creation of high-performance beads that maintain the functionality and cost-effectiveness of traditional plastic particles while ensuring full biodegradability.
The company's solutions serve a diverse range of industries, including cosmetics, life sciences, paints, coatings, and various industrial applications where microplastics are traditionally used as sensory enhancers, thickeners, carriers, or separators. By providing a sustainable, 100% bio-based alternative, Naturbeads helps partners meet evolving environmental regulations and reduce their ecological footprint. Having transitioned from its origins at the University of Bath to scaling up industrial production, the company has successfully established its first commercial manufacturing plant in Italy to meet growing global demand for eco-friendly, circular-economy materials.
