Resumen:
Una universidad española ha desarrollado un nuevo sistema basado en nanopartículas para eliminar microcontaminantes orgánicos en efluentes industriales o efluentes de tratamiento de aguas residuales. El sistema basado en enzimas ligninolíticas inmovilizadas utilizando nanopartículas magnéticas ha demostrado buenos resultados en un reactor a escala banco. Sus principales ventajas incluyen el alto porcentaje de eliminación de contaminantes orgánicos (BPA, MG, etc.), alta estabilidad del sistema y pocos requerimientos de limpieza. La universidad busca socios interesados en licenciar la tecnología o colaborar en su desarrollo.

Tittle:
System based on nanoparticles to remove organic recalcitrant pollutant.
Summary:
A Spanish university has developed a new system based on nanoparticles to remove organic micropollutants from industrial efluents or wastewater treatment efluents. The system based on ligninolytic enzymes immobilized using magnetic nanoparticles has shown very good results in a bench scale reactor. The university is looking for partners interested in licensing the technology or working together in the development of the technology.
Description:
The discharge into the aquatic environment of organic recalcitrant pollutants from wastewater treatment plants is a major environmental problem due to the possible adverse effects that these chemicals have on animals, plants and people. Among these, a group of micropollutants of natural and anthropogenic sources (e.g. pharmaceuticals, pesticides, cosmetics and personal care products, flame retardants, hormones and other industrial chemicals) may potentially alter the functions of endocrine system and therefore, cause adverse effects on an organism or its progeny. On the other hand, the use of synthetic chemical dyes in various industrial processes, including paper and pulp manufacturing, plastics, dyeing of clothes, leather treatment and printing, results in the release of dye-containing industrial effluents with recalcitrant nature.

Conventional systems of wastewater treatment are not designed to remove these compounds, and their removal is only partial. The technology developed by the Spanish university was adapted to remove these kinds of pollutants.

The invention comprises an organic recalcitrant pollutant removal system based on the use of ligninolytic enzymes. The enzymes are immobilized using magnetic nanoparticles. The system was tested in a bench scale reactor, where bisphenol A (BPA) and methyl green (MG) were present in the influent. The experiments carried out have shown very good results as more than 90% of bisphenol A (BPA) and 80% of the dye methyl green (MG) present in the influent were removed.

The university is looking for industrial partners willing to license the technology or further develop the technology.
Advantages and Innovations:
· High elimination percentage rate of organic pollutants (i.e. BPA, MG,...)
· High stability of the system
· Low cleaning requirements
Stage of Development:
Under development/lab tested
IPs:
Patents granted
CommeR Statunts Regarding IPR Status:
