Recycling process planning for the End-of-Life management of waste from electrical and electronic equipment

The ever-increasing amount of waste from electrical and electronic equipment (WEEE) has become a common problem due to the significant environmental and health impacts associated with inappropriate End-of-Life (EoL) management. The current ad hoc applications of WEEE recycling are often based on limited knowledge and cannot cope with the complex range of materials and products in such waste. A knowledge-based approach has been utilised to investigate the realisation of a recycling process planner which aims to determine the most suitable EoL options for WEEE. A number of case studies have been used to show that a 20-30% improvement on economical and environmental performance could be achieved through adoption of such a systematic approach to recycling process planning.

Self-assembling organomodified Co/Al based layered double hydroxides （LDH） via one-step route

The preparation of self-assembling organomodified Co/Al-layered double hydroxide (LDH) via one-step route was studied. A common surfactant, sodium dodecylbenzenesulfonate (DBS), was employed as an organic modifier. The behavior and structure of self-assembled intercalated organic Co/Al-LDH were investigated by FTIR, SEM, WAXS, element analysis and TGA. Based upon the WAXS results and calculation by Bragg equation, the interlayer distance (d value) for organic Co/Al-LDH is enlarged from 0.75 nm to 3.10 nm, showing that the self-assembling behavior has been carried out successfully. Considering the observation from SEM, the product shows the morphology of organic Co/Al-LDH of a layered structure. In addition, FTIR, element analysis and TGA analysis show that the modifier is intercalated into the gallery of the Co/Al-LDH. Since organic modification for nanofiller is deemed to be necessary before applying it into polymer, the successful preparation of organomodified Co/Al-LDH will be significantly beneficial to the preparation and investigation of novel polymer/LDH nanocomposite.     

Application of Plasma Technology in Iron and Steelmaking

The potential for the application of plasma technology in metal oxide reduction and in iron and steelmaking is outlined and discussed. Recent evolution and developments in the plasma-based reactors employed in the production of iron, steel, and ferroalloys have been reviewed; the current status is outlined in terms of process control, flexibility in the raw materials consumed, product quality, and energy conservation. The advantages and limitations of thermal plasma-based reactors have been critically outlined and their potential to seriously challenge the blast furnace/basic oxygen furnace steelmaking route is considered.     

Mechanofused powders for thermal spray

Mechanofusion is a novel powder processing technique, in which raw powdered materials are fed into the apparatus, and through mechanical-thermal interactions, the powder characteristics are changed, e.g., shape, size, and composition distribution. Mechanofusion has been used in this study to produce intermetallic nickel aluminide compounds and composite powders as feedstock for vacuum plasma spraying. Significant effects of the mechanofusion production route on the powder characteristics and spray deposition features have been observed.     

Corrosion behaviour of powder metallurgical and cast Al-Zn-Mg base alloys

The behaviour of Al-Zn-Mg base alloys produced by powder metallurgy and casting has been studied using potentiodynamic polarisation in 0.3% and 3% NaCl solutions. The influence of alloy production route on microstructure has been examined by scanning electron microscopy, Auger electron spectroscopy and secondary ion mass spectrometry. An improvement in performance of powder metallurgy (PM) materials, compared with the cast alloy, was evident in solutions of low chloride concentration; less striking differences were revealed in high chloride concentration. Both powder metallurgy and cast alloys show two main types of precipitates, which were identified as Zn-Mg and Zr-Sc base intermetallic phases. The microstructure of the PM alloys is refined compared with the cast material, which assists understanding of the corrosion performance. The corrosion process commences with dissolution of the Zn-Mg base phases, with the relatively coarse phases present in the cast alloy showing ready development of corrosion.
