PhD Studentship: Food Waste Valorisation

University of Reading - Department of Food and Nutritional Sciences

Supervisors:  Professor Charalampopoulos, Dr Afroditi Chatzifragkou, Dr Steve Elmore

Project Overview: 

Among vegetables, onion is the second most widely consumed crop, providing a relatively high value raw material for food industries. There are very large quantities of onion waste across current value chain (>6M tons in the Europe) which currently remain under exploited. The substantial amount of waste thus reduces the economic efficiency of the onion supply chain while also increasing the carbon footprint and environmental impact. The efficient food production with total usage of agricultural raw materials offers a wealth of opportunities for developing a smart circular economy. This proposal aims to develop technical understanding towards valorising onion side-streams using novel process technologies in order to create structuring ingredients and natural flavours, with the view to improve sustainability and create economic value for the food sector.

Major Skills/Techniques PhD student will be trained on:

  • Separation science & technology
  • Biotransformation of vegetable waste stream (enzymology/fermentation)
  • Bio-refinery concept including LCA modelling
  • General food chemistry/biochemistry


  • Applicants should hold or expect to gain a minimum of a 2:1 Bachelor Degree or equivalent in Food Science / Biotechnology or relevant subject.
  • Due to restrictions on the funding this studentship is open to UK applicants and EU applicants that are ‘ordinarily resident’ in the UK for 3 years continuously prior to the start of the grant.

Funding Details:   

  • The project is funded by the BBSRC Collaborative Training Partnerships (CTP) scheme and will be conducted in collaboration with Unilever as the industrial partner.
  • The PhD studentship covers a stipend of £16,553 per annum, research costs and tuition fees at UK/EU rate.
