Carbon-supported catalysts for sustainable biorefinery in water
A solvent-free ball milling protocol was investigated for synthesizing sustainable Sn-functionalized biochars for glucose isomerization to fructose. Raw wood biomass and its derived biochars pyrolyzed at low and high temperatures were investigated as catalyst supports. This study emphasized that the interactions between Sn and the carbonaceous supports were related to the surface chemistry of the catalysts. Functional group-enriched surfaces provide more active sites for anchoring Sn, resulting in a high loading on the biochar support. The annealing temperature was another critical factor that affected the concentrations and nature of the species of loaded Sn. The catalytic activity was correlated to the amount and nature of active Sn sites. This study elucidated the roles of the carbon support and annealing temperature for synthesizing biochar-supported catalysts, highlighting a simple and green approach for designing effective solid catalysts for sustainable biorefineries.

‘Pinching’ Eco Industrial Park: Maximising resource savings and minimising waste and emissions
Industries play a key role in providing continuous supply of human’s essential needs including food, chemicals, pharmaceuticals, building materials and equipment. Rapid population as well as industrial growth have been accompanied by rising demands for utility resources and widespread environmental pollution. Eco-industrial park (EIP) is the concept of industrial symbiosis between industries which are located within an industrial site. The concept of EIP became increasingly popular in the 1990s. It is reported by World Bank that there are already 250 EIP worldwide. The first modern EIP is Kalundborg in Denmark and is a reference for planners and industrial estates’ leaders. An EIP network of linkages leads to high levels of environmental benefits and economic efficiency apart from many other less tangible benefits. Major economic factors that influence the successfulness of eco-industrial networking are cost savings and enhanced competitiveness; reduced infrastructure costs; improved revenue generation; improved opportunity for investment (new businesses); job creation; improved human resources; and access to and development of new technologies. All these factors improve the competitiveness, attract investments, business retention, and community wellbeing. As many foreign companies are growing environmentally conscious, well developed and managed industries park such as Eco-Industrial Park (EIP) should be established to attract the foreign direct investment to foster the economic competitive development. Over the last four decades, Process Integration (PI) has emerged as a holistic approach for the optimal planning, design and retrofit of minimum resource utilisation networks. PI promotes symbiosis and synergy by maximising resource utilisation efficiency and minimising wastes among interacting processes, industry and systems. In this lecture, PI techniques are discussed in the context of Eco-Industrial Park planning and management.

Considering the ageing of membrane processes in water and wastewater treatment and recycling
Conventional membranes processes such as micro-, ultra-, nano-filtration, reverse osmosis and membrane bioreactors are now considered as options-of-choice for treatment of water and wastewater. Notwithstanding all the important process improvements and optimisations obtained through recent academic and industry research activities, the full maturity of those membrane processes is expected to be reached only after the development of standardised strategies for design, operation, maintenance and replacement. In particular, it is critical to appropriately understand and integrate the impact of membrane ageing and gradual degradation on the hydraulic and rejection performances of the processes. The talk will especially focus on recent study at UNSW to validate membrane bioreactors for water recycling and to demonstrate its reliability of rejecting viruses within the lifetime of the membrane. The talk will also demonstrate the need to better assess the relative impact of fouling over ageing of RO membranes and how new approaches in the management of online conductivity could result in significant financial savings for full-scale RO processes employed in water recycling schemes.
