Solidificación / Estabilización de residuos orgánicos mediante granulación con sepiolita

Abstract

[ES] Se estudia un proceso de solidificación/estabilización con sepiolita, de diversos tipos de residuos industriales conteniendo contaminantes orgánicos considerados tóxicos y peligrosos (pinturas, cosméticos, tensioactivos, resinas...). El proceso se realiza mezclando el residuo y la arcilla hasta obtener un material granulado, de baja humedad y punto de inflamación próximo a 100ºC. El tratamiento individualizado con sepiolita de cada uno de los residuos estudiados, indica que puede obtenerse un material adecuado para su almacenamiento en un depósito de residuos, o bien, un combustible de residuo (CDR) apto para su revalorización energética en hornos de fabricación de clinker. En el caso de un tratamiento conjunto de todos los residuos con la arcilla, se obtiene un material cuyo destino más adecuado sería su revalorización energética. La cantidad de arcilla utilizada varía según el tipo de residuo y está comprendida entre 0.3 y 0.6 kg/kg de inerte final. Se estudian y caracterizan químicamente cada uno de los materiales obtenidos. Finalmente, algunos de ellos se estudian mediante mediante microscopía de barrido a –190 ºC.

[EN] A solidification/stabilization process of different toxic and hazardous organic industrial wastes with sepiolite was studied. Wastes coming from, among other, paint, cosmetic, resin, liquid detergent industries were mixed with the clay. The process yielded granulated solids with low moistness and ignition point close to 100ºC. The materials so obtained can be stored into a waste deposit or used as a combustible to cement klin. This last option involves an energy recovery and accordingly allows the complete utilisation of a waste's calorific value. Clay/inert product mass rates ranged between 0.3-0.6, depending on the type of waste. Chemical characterisations of final materials were performed and crio-scanning electron microscopy (at –190ºC) were employed to study the sorption process.
