Introduction

This patented hydrogel is biodegradable and biocompatible. It can absorb large quantities of water and other compounds. In agriculture it could be useful to improve the germination rate of seed, or as a substrate for the release of nutrients and microorganisms. This material does not create polluting residue when dispersed in the environment.

Technical features

This biocompatible and biodegradable hydrogel is made of raw materials normally present in soil, that are convenient and easy to find. Its specific composition is designed to absorb and release elements and compounds of interest in a controlled manner, by transmitting and withholding them in the soil. This characteristic could be useful for the decontamination of water and soil or other applications that require massive or selective absorption. Further developments may lead to the use of the hydrogel in the sanitary or medical field. This material is therefore useful for all environmental applications since it does not leave polluting residue: it is quickly degraded by microorganisms, and decomposes into elements that are already present in soil.
