Jason Hallett

Prof Jason Hallett performs research involving the solution behaviour of ionic liquids and the use of ionic liquids in the production of lignocellulosic biofuels, sustainable chemical feedstocks, vaccine manufacturing and waste recycling (particularly for metal-contaminated solid materials). This research is supported by both the UKRI and industry.

Prof Hallett currently serves as a core member of the Supergen Bioenergy Hub and the Future Vaccines Manufacturing Research Hub.

He is also co-founder of 6 spin-out companies based on the group's research:

Lixea, a circular bioeconomy company which uses low-cost ionic liquids to fractionate waste biomass for biofuel, chemical and material production from cellulose and lignin. Lixea operates a pilot plant in Sweden for the Dendronic process, which is the commercial version of teh group's ionoSolv process.

Nanomox, which produces advanced materials, especially metal oxides, from metallic waste streams using the ionic-liquid based technology Oxidative Ionothermal Synthesis (OIS), developed in the group.

EcoSAF, which produces bio-derived furan-based surfactants for detergent and personal care applications. The surfactants demonstarte superior performance to petrochemical surfactants but are fully biodegradable, non-toxic and renewable. They have a similar cost point to market detergents.

DyeRecycle, which extracts dyes from waste textiles and transfers them to new fabrics, enabling easier textile recycling and creating the first circular dyeing process. DyeRecycle uses ionic liquids to achieve a waterless dyeing solution.

CO2Co, which is a recently launched direct air capture company developing extremely large-scale CO2 removal solutions.

Ionic Recovery, which is a circular economy company that de-metallizes a wide range of waste bio-based feedstocks, such as sewage sludge.

A very special company was also founded by one of the group's PhD studnts:

Oorja (Dr Clementine Chambon) is a social enterprise dedicated to changing teh lives of rural farmers i nIndia by bring solar electricity for irrigation, commercial and home use to communities without adequate access to power.

Prof Hallett received his PhD in Chemical Engineering from the Georgia Institute of Technology. He joined Imperial College, first with a Marshall-Sherfield Postdoctoral Fellowship in Sustainable Chemistry and in 2014 was appointed a Senior Lecturer in the Department of Chemical Engineering, before promotion to Reader in 2016 and Professor in 2018. He has authored over 150 articles and holds 10 patents.
