| The process is carried out in a tunnel oven that reduces costs and contributes to environmental sustainability | Researchers from the Polytechnic University of Cartagena have developed a novel microwave technology to dehydrate and sterilize fish waste from farmed farms and turn it into fish meal.

This is the first experience in Spain for the treatment of SANDACH (Animal By-products Not Intended for Human Consumption).

This development uses clean energy, reduces costs and contributes to environmental sustainability. The development has been carried out in the doctoral thesis of the Telecommunications engineer, Juan David Reverte Ors, "Design and implementation of a sandach sterilization and drying system with multimode, microwave technology and its transfer to industry livestock " Directed by Professor Juan Luis Pedreño and Professor Jos Fayos, from the Electromagnetism and Matter group of the UPCT. The trials have been carried out in the last four years within the framework of the research project of the former Ministry of Economy and Competitiveness (reference DPI2014-61857).

Reverte has processed the fish discards through a 12 kW tunnel furnace located in the spaces that the research group occupies in the UPCT Technology Park. Currently, fishing discards are either incinerated or are far from the port, which means transport and unsustainable, explains Reverte, manager of the Official College of Telecommunication Engineers of the Region of Murcia.

Microwave processing through a tunnel oven makes it possible for the fish farm to have that benefit: inactivate microbes and dehydrate it.

At the same time, it allows it to be reused in the same activity and in the facilities themselves. The application of the new technology complies with current regulations and contributes to reducing the environmental impact.
