Bioplastic polymers based on aromatic dicarboxylic acids derived from lignin

Lead Research Organisation: University of Leeds
Department Name: Sch of Chemistry

Abstract

Aromatic chemicals are crucial in bioplastics to convey functionality, including strength and flexibility. Currently, these aromatic chemicals can only be sourced from fossil based inputs, limiting applications, increasing the cost and environmental impact. Lignin, the 2nd most abundant organic polymer in plants, is one of the few potential natural sources of aromatic chemicals. Building on a successful feasibility study that proved that the aromatic diacids inherent within lignin could be extracted and substituted in polyester based plastics, this project aims to demonstrate that these metabolites can be produced in a commercially viable manner by the innovative use of modified bacteria to selectively control lignin disintegration when matched with novel chemical processes in scalable batch/continuous reactors. Larger trials will convert the resultant kg quantities of diacids into novel block copolyesters, for evaluation in a high value global bioplastics market of value >£150m.

Description A continuous flow process to produce kilograms of DFF and FDCA from lignin and metabolic precursors has been developed and scaled-up. This has involved a new reactor design used with multiple enzymes based on the procedure we published in doi.org/10.1002/anie.201803675.
Exploitation Route The processes being developed at Leeds are being adopted by collaborators at University of Manchester and in industry..

Title Laboratory scale continuous flow stirred tank reactors 
Description The ability to carry out continuous flow reactions in the laboratory with multi-phasic systems has been limited. A new magnetically stirred reactor (CSTR) with 2mL volume has been developed partly as a result of the chiral amine project. The Freactor is a multi-stage or cascade CSTR able to use and make mixtures of solids-gases and liquids to do chemical reactions that are useful in developing production processes. 
Type Of Material Improvements to research infrastructure 
Year Produced 2016 
Provided To Others? Yes  
Impact The Freactor is being used by more than a dozen other chemical labs in academia and industry, enabling them to evaluate reactions that were hitherto not possible. Talks are on-going with an equipment supplier to exploit this system and make it more widely available.

PI Contribution The Molecule to product CDT, about to start and run by the University of Leeds, is establishing collaborations with international institutions to both host PhD students, to enhance their training, establish research links, and to invite their experts to provide workshop training in Leeds. In this regard we are taking steps at establishing a formal arrangement where our collaborators at Mendeleev University can provide expertise in modelling and simulation that will continue to develop the research we have already started through the British Council Award, and also to deliver expert lectures and workshop to train PhD students in aspects of multi-scale modelling.

Title PROCESS FOR OXIDISING A SUBSTRATE 
Description A process for oxidising a substrate selected from hydroxymethylfurfural (HMF), diformylfuran (DFF), hydroxymethylfurancarboxylic acid (HMFCA) and formylfurancarboxylic acid (FFCA). Said process comprises mixing said substrate with catalase, one or more further enzymes and hydrogen peroxide to form a reaction mixture. Said one or more further enzymes have the ability to catalyse oxidation of said substrate. Said hydrogen peroxide is provided at a total molar ratio of at least about 0.1:1 hydrogen peroxide to substrate.
