The UK chemical sector has an annual turnover of over £32 billion with 99,000 direct jobs in 2016. The Centre's vision is to transform the UK's chemical industry into a fossil-independent, climate-positive and environmentally-friendly circular chemical economy. The overall novelty of our programme is the development of a sector-wide solution with deep circularity interventions, by creating a circular resources flow of olefin-the raw material for 70% of all organic chemical production. Our whole system approach will include key sectors of production, transportation/distribution, refinery/downstream, use and waste recycling, to reduce fossil reliance and improve productivity and sustainability of the whole process industry. The Centre will generate a cross-disciplinary platform combining synergistic innovations in science/engineering with social scientists to comprehend the whole system industrial symbiosis and market/policy/incentive design. The Core Research Programme is organised around three interconnected themes: (1) Key technologies to enable olefin production from alternative/recycling wastes streams and design more reusable chemicals via advanced catalytic processes; (2) Process integration, whole system analysis and value chain evaluation, and (3) Policy, society and finance. Through detailed process modelling, economic analysis and environmental assessment of technology solutions along the supply chain, accelerated understanding, opportunities and optimum solutions to achieve circularity of olefin-derived resources flow will be attained. These activities are embedded with stakeholders involving all affected groups, including local SMEs and downstream users, and will provide evidence and data for policymakers. The Centre will engage with users through social studies and organised events, and exploit consumer/business behavioural change related to chemical systems enabling a sustainable community and society with innovative technologies.

Carbon nanotubes (CNTs) are one of the most widely studied and commercially attractive nanoparticles studied to date. Their commercial success is best quantified by the production volume of CNTs, which is growing exponentially, and is currently estimated at 5000 ton/yr. In part, this success can be attributed to the physical properties of CNTs, some of which are unlike any other engineering material (e.g. Young's Modulus of 1 TPa, a tensile strength of 100 GPa, thermal conductivities up to 3500 Wm-1K-1). However, these off-the-chart properties only apply to high quality individual nanotubes whereas most commercial applications require tens to millions of carbon nanoparticles to be assembled into one device. Unfortunately, the mechanical and electronic figures of merit typically drop by at least an order of magnitude in comparison to the constituent nanoparticles once integrated into an assembly. It is therefore critical to develop new manufacturing processes which enable assembling CNTs in a controlled fashion and to integrate these CNT aggregates in devices. These devices are extremely challenging to manufacture reliably, not only because of challenges in the synthesis and assembly of CNTs but also because these fragile CNT structures need to be interfaced with electrodes for electrical read-out, and often need to be in contact with gases or liquids for sensing, microfluidic, biomedical and energy storage applications. In this EPSRC Adventurous Manufacturing grant, we demonstrate a multi-scale manufacturing approach that allows to individually optimise different device length scales in an approach that has never been attempted previously. Bringing these manufacturing methods together is challenging because they rely on different alignment processes and have different thermal budgets, but when integrated correctly, phase 1 of the project demonstrated that they enable the manufacturing of radically new nanomaterial based devices. Ultimately, this new set of manufacturing techniques form a platform technology that can be used to solve a multitude of engineering problems and find applications in chemical sensors, biomedical applications, microfluidics and actuators. This project is partnering with UK based manufacturing companies to ensure that the processes developed in this project are embedded in the UK industry and become easily accessible to both academic and industrial stakeholders.
