Dr Jannie S.J van Deventer (Zeobond Pty Ltd), Dr Mark Cooksey (CSIRO), Dr Alistair Woodard (TPC Solutions)
President's Room, 21 Bedford Street North Melbourne
This seminar will focus on low emissions innovations in the building and construction industry from three perspectives.
Alkali-activated cement (AAC) made from fly ash, metallurgical slags and natural pozzolans could reduce such CO2 emissions by at least 80% compared with Portland cement. However, the uptake of these materials is impeded by established practice and specifications based on Portland cement. There is also a scarcity of supply of source materials including fly ash, granulated blast furnace slag and alkaline activators.

Metals mining and production must achieve significant improvement in energy productivity, with attendant emission reduction to remain competitive in a carbon constrained world. . Process improvement opportunities in iron, steel and Aluminium may save these industries in Australia.

Timber as a Low Energy/Emissions Construction Material.Timber is being around the world as a major structural material in mid-rise commercial construction. Cross laminated timber (CLT), pre-tensioned timber beams, post-tensioned timber frames, and prefabricated timber systems offer low energy/emissions with a renewable construction material. Life cycle assessment and current requirements are barriers that Engineers can assist in overcoming.

Jannie S.J van Deventer is the Chief Executive Officer of Zeobond Pty Ltd in Melbourne. He holds doctorates in chemical engineering, mineral processing and business economics and served as Dean of Engineering from 2003 to 2007 at the University of Melbourne, where he is currently Honorary Professorial Fellow. He remains active in both mineral processing and cementitious materials, and has commercialised several technologies in the mining and construction industries. He has received several awards, including INNOVIC’s national “The Next Big Thing Award” for geopolymer technology in 2008.
Dr Mark Cooksey leads CSIRO’s process design research program. He has a PhD in Chemical and materials Engineering , BEng in Materials and BSc information technology. His work is in development and optimisation of new processes. This includes energy use and emissions in Aluminium, Iron & steel industries
He is responsible for 70 staff in a number of research areas supporting the minerals and process industries including:
- process development and optimisation, including flowsheet development, technoeconomic evaluation and life cycle assessment
- online analysis for control
- materials characterisation.
Mark will speak on energy productivity and emissions reduction through process improvement in metals industry.
Dr Alastair Woodard is a structural engineer and director of TPC Solutions (Aust) Pty Ltd, a consultancy specialising in advice on the use and impact of building and construction materials. He delivers a range of programs for Wood Products Victoria and Wood Solutions – a timber industry initiative, resourced by Forest & Wood Products Australia, designed to provide information on timber and wood products to professionals and companies involved in building design and construction. He has extensive experience in the design of timber structures and a particular interest in the use of sustainable building materials from a Life Cycle Assessment perspective
