The management of liquid manure generated by livestock farming is an environmental problem that affects soil, water and air when there is a high concentration. The [Solid State Chemistry Group](http://www.uji.es/serveis/ocit/base/grupsinvestigacio/detall?codi=019) at the Universitat Jaume I in Castelló, coordinated by Professor Juan Bautista Carda, has created an innovative method for treating and recovering liquid manure using laser technology.

The new system involves separating the solid and liquid parts using laser irradiation according to specific parameters to obtain high value-added products. The liquid part is then treated again with laser irradiation to adapt it for agricultural or industrial use.

This invention, applicable to the environmental and circular economy sectors, offers a number of advantages, including mitigating the risks associated with slurry saturation; purifying water and protecting available water sources; improving the quality of soils treated with slurry; and promoting the circular economy in line with the Sustainable Development Goals (SDGs) of the 2030 Agenda.

The process, validated on an experimental scale in a laboratory environment and protected by a Spanish patent application, seeks collaboration with companies for the development and adaptation of the technology in specific applications through specific agreements and subsequent licensing agreements.

The Solid State Chemistry research group maintains close collaborations with prestigious national and international research groups, especially with the Aragón Materials Science Institute, a joint center of the CSIC and the University of Zaragoza, in the field of laser technology and through the Associated Unit of Chemistry of Materials Processed by REMO (electromagnetic radiation).

The Universitat Jaume I, through the Office for Cooperation in Research and Technological Development and the Vice-Rector's Office for Innovation, Transfer and Science Outreach, facilitates the scientific and technological transfer of its research staff with the aim of advancing its vocation for the transmission and dissemination of scientific, technical, social and humanistic knowledge.

The research carried out to achieve this new system has been funded by the Strategic Subsidy Plan of the Provincial Council of Castelló (2020-2022); the MCIN/AEI and the European Union NextGenerationEU/PPTR (CLUSCERM: TED2021-130963B-C22; FOTOCER: PID2020-116149GB-I00 and MATER-ONE: PID2020-116719RB-C43); the CLUSKER project: INNEST/2024/420 funded by IVACE (2024-2026) and the Chair in Ceramic Innovation “Ciutat de Vila-real” at the Universitat Jaume I in Castelló.
