Particulate materials account for over 60% of all the industrial products and are of significant importance to the global economy, society and environments. Examples of these materials include dusts, pollutants, catalysts, protective coatings, composites, photocopy and printer toners, cosmetic pastes, pharmaceutical drugs, fertilizers, cement, solids fuels, and foodstuff. However, manufacturing, handling and processing of such materials still face numerous challenges. Both UK and China have developed large communities in particle science & technology in the past few decades for addressing these challenges. In order to facilitate communications and to foster collaborations between the communities in the two countries, the UK-China Particle Technology forum, which is a non-profit event series and is run every two years in rotation between UK and China, was initiated in 2006. The forum aims at1) Enhancing communications between scientists and engineers from both academic institutions and industrial companies of the two countries;2) Establishing a platform to foster new and substantial collaborations to identify and address common challenges in particle technology.The UK-China Particle Technology Forum III continues the primary objective of the two previous forums, which were successfully held in Leeds, UK (2007) and Guiyang, China (2009), to provide opportunities for scientists and engineers to discuss recent advances, to share knowledge and to identify future collaborative research directions in the field of particle science & technology and their roles in environment, energy, healthcare and other emerging applications. It also aims at consolidating the collaborations established through the two previous forums and fostering new collaborations between UK and China.

Meeting the Paris climate change commitments will be extraordinarily challenging, and even if they are met, may require extensive global deployment of greenhouse gas removal (GGR) technologies resulting in net negative emissions. If certain major emitters do not meet their Paris commitments and/or wider international cooperation is reduced then the trajectory needed to reduce emissions to Paris levels after a delay will be even more severe, potentially leading to the need for even greater reliance on such net negative emissions technologies. At present, the technical feasibility, economics, implementation mechanisms and wider social and environmental implications of GGR technologies remain relatively poorly understood. It is highly uncertain that GGR technologies can be implemented at the scales likely to be required to avoid dangerous climate change and without causing significant co-disbenefits or unintended consequences. Our GGR proposal presents a unique combination of a multi-scale assessment of the technical performance of GGR technologies with an analysis of their political economy and social license to operate, with a particular focus on how these elements vary around the world and how such considerations impact region-specific GGR technology portfolios. Currently, some portray GGR technologies as a panacea and virtually the only way of meeting aggressive climate targets - an essential backstop technology or a 'bridge' to a low-carbon future. One part of our project is to work with the models of the global economy (integrated assessment models) and better reflect these technologies within those models but also to use models at different scales (global, regional, national, laboratory scales) to understand the technologies better. We also seek to better understand how deployment of these technologies interact with the climate system and the carbon cycle and what the implications are for the timings of wide-scale rollout. By contrast, sceptics have expressed concerns over moral hazard, the idea that pursuing these options may divert public and political attention from options. Some critics have even invoked terms such 'unicorns', or 'magical thinking' to describe the view that many GGR technologies may be illusory. We will seek to understand these divergent framings and explicitly capture what could emerge as important social and political constraints on wide-scale deployment. As with nuclear power, will many environmentalists come to view GGR technologies as an unacceptable option? Understanding the potential scaling up of GGR technologies requires an understanding of social and political concerns as well as technical and resource constraints and incorporating them in engineering, economic and climate models. This aspect of our proposal necessarily brings together social science, engineering and environmental sciences. What is the biggest challenge to scaling up BECCS for example? Is it the creation of the sustainable biomass supply chain, the deployment of CO2 capture technology or the transport and storage infrastructure that is rate limiting? Or is it more likely the social acceptability of this technology? Further, we will provide insight into the value of international and inter-regional cooperation in coordinating GGR efforts. For e.g., would it make more sense for the UK to import biomass, convert it to electricity and sequester the CO2, or would it be preferable pay for this to happen elsewhere? Conversely, how might the UK benefit from utilising our relatively well characterised and extensive CO2 storage infrastructure in the North Sea to store CO2 on behalf of both the UK and others? More generally, we will explore how stakeholders in key regions view the suite of GGR technologies. Finally, we will quantify the option value of GGR - what is the value in early deployment of GGR technologies? How does it provide flexibility in meeting our near term carbon targets?

Sustainability is defined as "the ability to meet the needs of the present without compromising the ability of future generations to meet their own needs". Achieving sustainable development is the key global challenge of the 21st Century. It can only be met with the adoption of a range of new sustainable technologies. Sustainable chemical technologies are those involving chemistry as the central science. They span a wide range of areas, many of which make major impacts on society. Key sustainable chemical technologies include: use of renewable resources and biotechnology (e.g., making fuels, chemicals and products from biomass rather than petrochemicals); clean energy conversion and storage (e.g., solar energy, the hydrogen economy and advanced battery technologies); sustainable use of water (e.g., membrane technologies for water purification and upcycling of nutrients in waste water); developing sustainable processes and manufacturing (e.g., making production of chemicals, pharmaceuticals and plastics more energy-efficient and less wasteful through developing sustainable supply chains as well as through technological advances); and developing advanced healthcare technologies (e.g., developing new drugs, medical treatments and devices). To address these needs, we propose a Centre for Doctoral Training (CDT) in Sustainable Chemical Technologies. The £5.08m requested from the EPSRC will be supplemented by £2.0m from the University and a £4.13m industrial contribution. The CDT will place fundamental concepts of sustainability at the core of a broad spectrum of research and training at the interfaces of chemistry, chemical engineering, biotechnology and manufacturing. This will respond to a national and global need for highly skilled and talented scientists and engineers in the area as well as training tomorrow's leaders as advocates for sustainable innovation. All students will receive foundation training to supplement their undergraduate knowledge, in addition to training in Sustainable Chemical Technologies. Broader training and practice in public engagement and creativity will encourage responsible innovation and attention to ethical, societal, and business aspects of research. They will all conduct high quality and challenging research directed by supervisory teams comprising joint supervisors from at least two of the disciplines of chemistry, chemical engineering, biotechnology and management as well as an industrial and/or international advisor. The broad research themes encompass the areas of: Renewable Resources and Biotechnology, Energy and Water, Processes and Manufacturing and Healthcare Technologies. Participation from key industry partners will address stakeholder needs, and partner institutions in the USA, Germany, Australia, and South Korea will provide world-leading international input, along with exciting opportunities for student placements and internships. The CDT will utilize dedicated physical and virtual space for the students as well as a supervisory base of more than fifty academics. Building on the success of the current Doctoral Training Centre and evolving to keep pace with the growing importance of biotechnology and manufacturing to UK industry, the centre will provide a dynamic and truly multidisciplinary environment for innovative PhD research and training.
