R2EM - Resource Recovery and Environmental Management
R2EM group is developing research activity on development of sustainable urban and industrial waste management cycles based on resource recovery approaches promoting circular solutions of waste to product and waste to energy. Research also involves efforts on developing environmental remediation solutions for soils and ground water remediation, process and environmental monitoring and environmental risk assessment on ports.

Boron removal from aqueous solutions by using a novel alginate-based sorbent: Comparison with Al2O3 particles
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-09-01)
Article
Open AccessBoron removal was evaluated in the present work by using calcium alginate beads (CA) and a novel composite based on alginate–alumina (CAAl) as sorbents in a batch system. The effects of different parameters such as pH, ... -
Strategies for surface modification with Ag-shaped nanoparticles: electrocatalytic enhancement of screen-printed electrodes for the detection of heavy metals
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-09-30)
Article
Open AccessScreen-printed carbon nanofiber electrodes (SPCNFEs) represent an alternative with great acceptance due to their results, as well as their low impact on the environment. In order to improve their performance, in the present ... -
Metal recovery by ion-exchange resins from municipal incinerated bottom ash
(2019)
Conference lecture
Open AccessMunicipal waste incineration plants produce large amounts of bottom ashes, being higher year over year. In order to follow the circular economy scheme proposed by the EU, a recovery step is required to valorise the high ... -
Recovery and separation of valuable metals (copper and zinc) from acidic mine waters by ion-exchange resins
(2019)
Conference report
Open AccessMining wastewaters, containing heavy metals such as copper (Cu) and zinc (Zn), have a huge impact on the environment due to they are not biodegradable and tend to bioaccumulate in plants or living organisms. Therefore, in ... -
Ion-exchange resins for metals recovery (Cu and Zn) from acidic mine waters
(2019)
Conference lecture
Open AccessEnvironmental and economic concerns over the last decades have introduced new research opportunities for the application of several techniques in order to improve the removal of contaminants, as well as to explore methods ... -
Recovery of sulphuric acid and valuable metals (Zn, Cu and REE) from acidic mine waters using nanofiltration
(2019)
Conference lecture
Open AccessAcidic mine waters (AMWs) contains moderate concentrations of sulphuricacid, relatively high concentrations of metals (Al, Fe, Cu and Zn) and minor amounts or rare earth elements (REE). The established management routes ... -
Non-dispersive extraction of ge(IV) from aqueous solutions by cyanex 923: Transport and modeling studies
(Multidisciplinary Digital Publishing Institute (MDPI), 2019-06-11)
Article
Open AccessTransport process of germanium from an aqueous solution containing oxalic acid and 100 mg/L Ge was studied. Cyanex 923 immobilized in a polytetrafluoroethylene membrane was employed as a carrier in a flat-sheet supported ... -
Transient membrane potential after concentration step: A new method for advanced characterization of ion-exchange membranes
(2019-09-01)
Article
Restricted access - publisher's policyA better understanding of ion-transport mechanisms requires separate information on the equilibrium (partitioning) and kinetic (diffusivity) properties of the membranes with respect to ions. This work presents a novel ... -

Increasing sustainability on the metallurgical industry by integration of membrane nanofiltration processes: acid recovery
(2019-11-01)
Article
Restricted access - publisher's policyThe metallurgical industry generates large volumes of toxic effluents characterised, generally, by high acidity and a noticeable content of metals (Fe, Cu and Zn) and non-metals (As, Sb, Bi). The toxicity of these streams ... -
Selective separation of Germanium(IV) from simulated industrial leachates containing heavy metals by non-dispersive ionic extraction
(2019-06-15)
Article
Restricted access - publisher's policyGermanium can be found in industrial leachates of coal gasification fly ashes or zinc plant residues, containing various heavy metals. In this research, the selective separation of germanium from simulated water coal ...
