Electrochemical and Environmental Engineering Resource Recovery: There is increasing economic and public pressure on industries to reduce the amount of waste being sent to landfill.rejected solids and liquids. The technology for treating these complex wastesmaterial streams does not often exist and requires fundamental research to characterize the chemical and physical properties of the wasterejected material before suitable unit operations can be designed. Wastes that have been studied include flyash, steel flue dusts, sulphite scrubbing solids and aqueous phenolic and cyanide effluents, tailings ponds residues and biomaterial residues. Hydrometallurgical research involves the study of extraction, separation and recovery of metal values from ores, by-products and wastes. The driving force for this work is the increasing emphasis, because of environmental regulations, on waste reduction and recycling. Electroorganic work requires the activation of weakly or nonpolar species through the use of imposed potential fields and relies on the use of specific very high surface area electrodes, typically in a packed bed configuration for uniform potential distribution. Electrochemical oxidations often mirror organic degradation processes in the environment but have the advantage of much more rapid initiation, ease of control and immunity to bacteriocidal action. With all electrochemical and environmental research, the electrolyte-electrode interface is of fundamental importance, since this is the region of electron transfer. Significant advances to electrochemical processing are being made through the use of chemically modified electrode surfaces, the control of electrode composition and by the design of the surface structure and configuration. Thus the research conducted is multidisciplinary and combines engineering with fundamental science.
