    Abstract: Potential CO2 leakages from CCS storage sites and accidental chemical spills change the pH of the seawater decreasing it to extreme pH values in specific sea areas for a limited period of time. These acidic pH values cause the release of pollutants from sediment and provoke toxic effects to receptor organisms.

    Abstract: The main pollutant release of stabilised electric arc furnace dust has been studied using column leaching tests at field-scale. The pH value and the concentration of Cd, Mo, Pb and Sb have been analysed in the leachates. Two mathematical models have been used to explain the experimental results. A model based on continuous stirred tank reactor (CSTR) considering that the leaching behavior is mainly due to variations in the chemical conditions; and a second model based on the advection-dispersion procedure. The best results have been obtained taking into account not only the mass transport of the pollutants from the solid to the liquid phase but also the resistance of the mass transfer into the solid phase.

    Abstract: The contribution shows the approaches to valorize the main compounds of the spent sulfite liquor from digestion process: (i) improving delignification step of the wood chips avoiding sugar denaturalization and the inhibitor compounds for the next fermentation processes, and (ii) completing the depolymerization of the carbohydrate polymers, obtaining the same quality of dissolving pulp.

    Abstract: The main objective of this work is the development of the model which predicts the mobility of Pb and Zn under different scenarios of contaminated sediment-CO2 acidified seawater contact. The equilibrium results are fit to Freundlich isotherms and the adjusted parameters have been calculated. A porosity kinetic model of the evolution of Pb and Zn concentrations with L/S is proposed; the model allows to estimate the superficial diffusivity of the intra-particle Zn and Pb parameter as 5.43·10-12 cm2/s and 1.05·10-12 cm2/s, respectively.

    Abstract: The aim of this work is the study of acid hydrolysis of the spent sulfite liquor at different conditions at laboratory scale in order to obtain fermentable sugars. The kind and concentration of acid, temperature and time of the process have been studied as process variables in the reactors based on previous studies. The obtained results give the optimal conditions of the acid hydrolysis for the valorization of this kind of lignocellulosic waste in bioethanol.
