A sustainable society will use manufacturing processes that satisfy the key criteria of resolving societal needs in the ways that do not deplete resources and do not harm the environment.
In order to understand implications of a given technology (or a manufacturing process) on resources and on the environment we need to place it within the context of a wider system. Thus, if we are considering a single reaction step, we need to understand also the complete process, including any separation requirements and sources/destinations of feedstocks and products/byproducts. If we are considering whether a given chemical product is better sourced from a renewable biofeedstocks, or from a petrochemical source, then we need to understand the supply chain and life cycle environmental implications of such a substitution.
Sustainable Reaction Engineering group is developing new reactor concepts based on intensive reaction conditions, novel materials, sensor and control strategies. We are working with both, petrochemical and renewable biofeedstocks supply chains, and are interested in whole process design and sustainability assessment.
In the light of growing sustainability concerns the possibility of deriving many of the end-use molecules from biomass is receiving increasing attention. One of the key challenges encountered here is the choice of starting materials, of target molecules and of processing routes, making treatment very expensive computationally and highly uncertain from the point of view of business and technology development.
Within the EPSRC funded collaborative project on the terpene-based supply chain, let by University of Bath and involving University of Bristol and Institute for Manufacturing at Cambridge, we are looking at methods of optimising different process scenarios based on several potential synthetic pathways. Here we began exploiting tools of data-mining, automatic evaluation of process routes and global multi-objective optimisation using non-gradient methods.
Together with Dr Andrew Flewitt and Prof. Richard Prager (Engineering), and Dr Cate Ducati (Materials and Metallurgy) we are involved in Horizon 2020 project "RECOBA" (www.spire2030.eu/recoba). The project is developing new control strategies for batch processes in several process industries sectors: polymers, steel and silicon. Our team is involved in developing and testing sensors for detection of soft particles morphology under process conditions. As project develops we established a new collaboration with Dr Alessio Zaccone in this Department to develop a fundamental theory of Raman scattering from polymer particles.
Within Catalysis@Cambridge research network we are working together with Prof. Matthew Gaunt group (Chemistry @ Cambridge) on developing scalable continuous flow C-H activation reactions. For this collaboration we exploit the broad range of operating conditions accessible in continuous flow reactors, as well as the tools of computational chemistry, model-based design of experiments and statistical DoE.
We continue work on Design of Experiments algorithms for developing complex organic syntheses. This is a collaboration with Dr Lucy Colwell and Prof. Jonathan Goodman (Chemistry) and is supported by industry.
Our group is involved in C4T project of CARES (http://www.cares.cam.ac.uk). The work package IRP1 of C4T project is concerned with developing catalytic technologies for de-carbonisation of chemical industries. Specifically we are concerned with replacing conventional feedstocks with C1 and bio-waste based feedstocks.
