Prof. Dr. PAUL A. BINGHAM
Glasses And Ceramics
Sheffield Hallam University, UK
Professor Paul A. Bingham gained a BEng (Hons) degree in Materials Science and Engineering from the University of Sheffield in 1995. He then pursued PhD studies, also at the University of Sheffield, on the topic of glass science and technology, and was awarded his PhD in 2000. In 1999 Paul joined Glass Technology Services Ltd as a Glass Technologist, and was promoted to Senior Glass Technologist in 2002. In this role Paul carried out industrially-focused R&D and problem-solving, ranging from development of new environmentally-friendly glasses to forensic examination and glass plant production problems. In 2004 Paul returned to academia, joining the Immobilisation Science Laboratory (ISL) at the University of Sheffield as a Postdoctoral Research Associate. In this role Paul worked on glasses and ceramics for the safe immobilisation of radioactive and toxic wastes, and also on energy-friendly materials development and waste management. Paul joined Sheffield Hallam University in January 2012 as a Senior Lecturer in Materials Engineering, and became a Reader in Materials Engineering in 2015 and Professor of Glasses and Ceramics in 2018. He contributes to teaching of Materials Engineering, with specific focus on materials composition / structure / property relations; and ceramic and glass technology. To date Paul has published over 90 research papers in the fields of glasses; glass-ceramics; energy and the environment; waste management and nuclear and toxic waste treatment; advanced spectroscopy; and manufacturing technologies. He has co-edited and co-authored a book on the subject of low-energy, environmentally-friendly glass manufacture and he has a strong track record in attracting research funding from bodies as diverse as UK Research Councils, Innovate UK, BEIS, European Union, US Department of Energy and industry. He currently holds a number of active research grants. He is Director of Studies for several PhD students and line manages many postdoctoral researchers, visiting academics and interns. Paul is a Fellow of the Society of Glass Technology and sits on its Basic Science and Technology Committee. He is a Fellow of the Higher Education Academy and is also a member of the Institute of Physics and the Association for the History of Glass. He is a reviewer for over 10 international journals, the US DoE Nuclear Energy Universities Programme and EU H2020 funding bids. Paul sits on several international and national committees. He is a member of the International Commission on Glass Technical Committee 5: Waste Vitrification and the RAL-ISIS Neutron User Committee. He was elected onto the Sector Decarbonisation Roadmap Committee for the ceramics industry, which directly advises the UK Government in this area. He is also a lead Academic Advisor to Glass Futures, which aims to develop a state-of-the-art training and R&D facility in glass. Paul also carries out a wide range of consultancy activities. He has consulted for the UK Government's Committee on Climate Change and for the ceramics, optoelectronics and glass industries. He also acts as an international expert witness and has worked with some of the world's largest and most well-known companies in his field. He has organised multiple conferences and was Chair of the Local Organising Committee for the highly successful Centenary Conference of the Society of Glass Technology in 2016. He has given many Invited Presentations at international conferences, and actively engages with the international academic and industrial communities.
Towards More Sustainable Glass Manufacture: Balancing Economic, Energy and Environmental Factors
Glass is a material that is fundamental to human society and its technological developments, from architectural and container applications to smart devices and optics. The global glass and glass products market set to reach $250BN by 2020, yet, with 1% of the entire global energy demand, the glass industry is a major industrial source of CO2 emissions.
Many efforts are underway globally to reduce CO2 emissions and the glass industry is playing a role in achieving the strict CO2 emissions limits placed upon it by legislation. However, much remains to be done and scientific and technological developments must be developed and implemented, to help manufacturers meet these demanding targets.
Our research, over many years, and working closely with international glass industry partners, has aimed to help the glass industry meet these CO2 reduction targets, both through reduced fuel (=CO2) and reduced carbonate (=CO2) raw materials, through 3 main routes, each of which will be discussed here:
1. Compositional reformulation. This consists of reformulating the final glass composition in order to reduce the high-temperature viscosity whilst retaining all of the properties and characteristics that make the glass easy to manufacture and use. Our research includes compositional reformulation in order to achieve this and examples from our work will be discussed.
2. Raw materials reformulation. This involves introducing new and alternative raw materials (including by-products from other processes) to augment or partially replace existing raw materials. Our current research includes the use of biomass ashes as glassmaking raw materials and this will be discussed here.
3. Raw materials consolidation. This consists of pelletisation or briquetting of raw materials, or a selection thereof, to enhance melting rates and thus reduce specific energy consumption. A specific example of briquetting of cullet fine particles will be presented here.
Balancing the economic-, energy-, technical-, scientific- and environmental-considerations is highly challenging. Here the author will illustrate the relevant factors and considerations, with the aim of stimulating ideas, debate and discussions around this interesting and vitally-important area of glass science and technology.
