Calculation of chemical and phase equilibria
… from flash calculations to distillation and pyrometallurgy. Despite the firm theoretical foundations on which the theory of chemical equilibrium is based there are two major difficulties that prevent the equilibrium state from being accurately determined. The first of these hindrances is the …

Bio-engineered gas diffusion electrodes (GDEs) for proton exchange membrane fuel cells (PEMFCs)
… costs per unit. Current hydrometallurgy and pyrometallurgy techniques do not provide a ‘clean’ or economically viable solution to PGM recovery when compared to bio-hydrometallurgy. Bio-catalysts can be manufactured by coupling the oxidation of hydrogen to the reduction of soluble metallic …

Design and evaluation of a novel process for the recovery of Cu and Au from waste printed circuit boards
… conventional processing plants which use various pyrometallurgy and physical separation techniques. The primary aim of this project was to contribute knowledge to the development of a hydrometallurgical processing plant for Au recovery from WPCBs, which can be applied in real-life industrial-scale …

The recovery of valuable base metals from electronic waste using a biological matrix extracted from Black soldier flies
… health hazards. E-waste metal recycling using pyrometallurgy is limited to secondary smelter feed and there are limited industrial plants dedicated solely for this purpose. While in hydrometallurgy, research in e-waste metal recycling has been largely focused on metal extraction whilst …

Employing heat pumps to recover low grade industrial thermal resources for space heating and cooling
The use of heat pumps to upgrade and recover low grade industrial thermal resources is an opportunity for industry to deliver low cost space heating at a reduced carbon footprint. Heat pumps also offer the potential to provide space heating and space cooling from a single unit. To facilitate rapid …
