• #### Sustainability within the polyester value chain ﻿

(Department of Chemical Engineering and Biotechnology, University of Cambridge, 2015-06-30)
Polyethylene terephthalate (PET) is used to make textile fibres, bottles and packaging films. The global production in 2013 was 65 Mt, growing at 5-7% per year over the last decade. PET is manufactured by the continuous ...
• #### Fundamental studies of heap leaching hydrology using magnetic resonance imaging ﻿

(Department of Chemical Engineering and Biotechnology, University of Cambridge, 2013-10-08)
The recovery of mineral from ore in the heap leaching process requires the mineral to come into contact with the leaching solution. However, heap hydrology is prone to non-uniform behaviour due to the inhomogeneity of the ...
• #### Improved production of poly(hydroxybutyrate) and related enzymes ﻿

(Department of Chemical Engineering and Biotechnology, University of Cambridge, 2013-02-05)
Polyhydroxyalkanoates (PHAs) are biodegradable, thermoplastic polymers that are produced by a wide range of bacteria in response to nutrient limitation and function as carbon and energy storage molecules. They have a wide ...
• #### Development and characterisation of a copper-based oxygen carrier for chemical-looping with oxygen uncoupling (CLOU) ﻿

(2016-02-02)
In chemical-looping, a fuel is oxidised by a solid metal oxide, MeO, in one reactor: (2$n+m$)MeO+C$_{n}$H$_{2m}\rightarrow$(2$n+m$)Me+$m$H$_{2}$O+$n$CO$_{2}$. The exit gas yields pure CO$_{2}$ after the steam has been ...
