A sustainable society will be built upon manufacturing processes that satisfy 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, target molecules and 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.
The group recently completed the Horizon 2020 project "MEASURE" (www.spire2030.eu/measure). This was a coordination and support action (CSA) project, which aimed to develop a roadmap towards harmonised cross-sectorial sustainability assessment in the European process industries. The project was coordinated by Friedrich-Schiller-Universität Jena (Dr Dana Kralisch) and also included Universities of Manchester and Ghent, Technische Universität Berlin, Evonik Industries, Procter & Gamble Services Company and ThyssenKrupp Steel Europe. The roadmap is now available on the project web page.
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). This project is coordinated by BASF. 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.
Within Catalysis@Cambridge research network we are working together with Prof. Matthew Gaunt group on developing scalable continuous flow C-H activation reactions. We are also continuing the work on Design of Experiments algorithms for developing complex organic syntheses.
