Biography

Research Groups: Advanced Materials Engineering and  Sustainable Environments. BIOGRAPHY - Research in Advanced Materials Engineering: Hadj has been the principal investigator of over 20 EPSRC research awards since 1980 and has published over 100 papers in learned journals and conferences in the area of coating flows, viscous mixing and polymer processing. He leads with Professor Coates the University of Bradford Advanced Materials Engineering Research & Knowledge transfer Group integrated within the IRC in Polymer Science and Technology. This international research Centre is equipped with some of the most advanced experimental and computer modelling facilities to be found anywhere in the world. Some 50 researchers supported by EPSRC, DTI and 45 collaborating companies are presently involved in research in polymer rheology, process measurements, analysis and control, new process development and computer modelling of polymer processing operations and thin film coating science and technology. Professor Benkreira's research focuses on developing new processes to manufacture materials with advanced properties such as coatings, nanocomposites and other structured materials. Linked to this theme is his fundamental research on applied rheology in polymer processing operations and coating flows where these materials are produced. Research in Sustainability: Professor Benkreira's interest in Sustainability stems from his research to develop new acoustic and thermal insulation products using polymeric wastes residues that are normally dumped in landfills as the starting material. He has collaborated with European scientists in the multi-millions euros HOSANNA EU project (see www.greener-cities.eu) which resulted in the development of a toolbox for the reduction of road and rail traffic noise in the outdoor environment throughout Europe. Professor Benkreira's contribution was to design acoustic and thermal insulation materials structures using elastomeric waste such as those produced by the car industry (rubber residues of tyres, bumpers, upholstery), waste carpets, tiles, etc. Current Senior Research Associates: Professors Phil Coates, Martin Gale,  Adrian Kelly, Ben Whiteside, Dr Raj Patel, Amir Khan, Michael Martyn.  Doctoral Research Associates:  Yusuke Shibata: High Speed Reverse Roll Coating: Toyobo, Japan; Sreedhara Sarma: High Speed Deformable Roll Coating, Tata Steel; Richard Alpin: Fluid mechanics of multilayer coating dies, EPSRC/Tata Steel;  Sararat Mahasaranon: Foaming of Polymer Composites, Thai Government; Atif Khan: Polymer Nanocomposite, EPSRC ; Abdelrahim Elgadafi: Wax Deposition in Pipeline Flow of Waxy Crude Oils, Libya National Oil Corporation;  Miss Mohamed Fathia: Rheology of Inhibitor of Waxy Crude Oils, Libya Petroleum Institute; Abukader Fakroun: Wax Deposition in Pipeline Flow of Waxy Crude Oils,  Libya National Oil Corporation, Naeem Al-Hilo: Acoustic and heat insulation materials, Irak Government, Khalid Nasir, Acoustic and heat insulation materials with fire retardancy, KTP.

Over 300 million tonnes of plastic is produced annually and this is expected to double over the next 20 years. Plastics have become vital materials in many aspects of everyday life but the generation of plastics solid waste (PSW) is becoming an increasing problem, for example 8 million tonnes of plastic waste finds its way into the oceans each year, having a huge impact on marine ecosystems. Some relatively clean and easy to separate types of waste plastics can be recycled economically, such as drinks bottles, and levels of recycling are increasing but many polymeric materials are much more difficult to recycle, for example composites containing different materials of polymers which cannot be re-melted such as rubber tyres and printed circuit boards. As such there is an urgent need worldwide to develop new technically and economically feasible methods to recycle these types of materials. This aligns with the concept of a circular economy which seeks to keep products and materials in use and design out waste and pollution. Our joint UK-China team aims to develop an industrial scale continuous process to successfully recycle and re-manufacture currently difficult to recycle bulk waste streams, with high efficiency. A continuous milling process will be developed to break down solid polymeric waste into fine powders with controlled properties, which can then be reprocessed into value-added products. We will perform experiments to understand the mechanisms of the milling process and how these can be opitimised for particular waste streams. We will characterise the materials produced and examine different ways of turning these powders into useful, value-added products. We combine unique skills and strengths of our Chinese and UK groups to address key issues facing both of our countries - effectively reducing the significant amount of plastic waste with efficient routes to re-use. This proposal builds on the highly successful research collaborations over the last decade between the world-class research laboratories of the Polymer IRC at Bradford and Sichuan University State Key Laboratory for Polymer Materials Engineering (SKLPME), an important and international award-winning part of our RCUK Bradford Science Bridges China platform.
