    Ficha Evaluación y validación de sistemas de desinfección alternativos al hipoclorito de sodio en industrias de IV Gamma

    La creciente demanda del consumidor de productos convenientes, de alto valor nutricional y seguros, ha impulsado los últimos años el aumento del consumo de alimentos de IV gama, listos para consumir o cocinar, que mantengan sus propiedades nutricionales y de frescura. Durante el procesado de estos productos, no existe ninguna etapa que garantice la eliminación total de los microorganismos presentes, siendo la etapa de desinfección la única en la que se puede reducir la contaminación microbiológica y garantizar su seguridad. Actualmente, el desinfectante más utilizado es el cloro, en forma de hipoclorito de sodio. La eficacia del cloro en el material vegetal está limitada entre 1 y 2 reducciones logarítmicas incluso a altas dosis. Además, es muy reactivo, reaccionando rápidamente con la materia orgánica, el aire y la luz. Por eso, el agua se suele hiperclorar (entre 50 y 200 ppm), lo que puede causar la generación de cloro gas en las instalaciones y, en contacto con la materia orgánica, puede llevar a la producción de cantidades excesivas de subproductos no deseables y potencialmente tóxicos (principalmente compuestos trihalogenados). Es por ello que en algunos países de la UE ya se ha prohibido su uso. Los últimos años, se están investigando otras alternativas a su utilización, por ejemplo, el ozono, el dióxido de cloro y el ácido peracético, entre otros.

    A Bio-inspired Multilayer Drainage System

    Document

    Agricultural run-off and subsurface drainage tiles transport a significant amount of nitrogen and phosphorus leached after fertilization. alchemia-nova GmbH in collaboration with University of Natural Resources and Life Sciences, Vienna developed two multi-layer vertical filter systems to address the agricultural run-off issue, which has been installed on the slope of an agricultural field in Mistelbach, Austria. While another multi-layer addressing subsurface drainage water is implemented in Gleisdorf, Austria. The goal is to develop a drainage filter system to retain water and nutrients. Both multi-layer filter systems contain biochar and other substrates with adsorption properties of nutrients (nitrogen, phosphorus). The filter system can be of practical use if an excess of nutrients being washed out is of concern in the fields of the practitioner by keeping the surrounding waters clean. This approach may result in economic value by re-using the saturated biochar as fertilizer and improving the soil structure, thus increasing long-term soil fertility.

    NANOCELLULOSE MEMBRANES FOR NUTRIENT RECOVERY

    Document

    This project has received funding from the European Union’s Horizon 2020 research and innovation program under Grant Agreement No 858735This project has received funding from the European Union’s Horizon 2020 research and innovation program under Grant Agreement No 858735. FACTSHEET NANOCELLULOSE MEMBRANES FOR NUTRIENT RECOVERY Key information Functionalized nanocellulose membranes can take up nitrate and phosphate. These membranes can be put in a water treatment unit. As the membranes are biobased, degradable materials, they can after use be added to the soil, thus returning the leached nutrients back for their original purpose providing fertilizers (nutrient recycling).

    Environmental monitoring within greenhouse crops using wireless sensors

    Document

    Because variables such as temperature and humidity have a profound effect on the activity of crop pests, diseases and natural enemies, the ability to monitor environmental conditions within a crop has always been important for crop protection.
