Reduce household food waste by using intelligent technology

   Electronic and Electrical Engineering

  Dr Ruiheng Wu, Dr Lu Gan  Applications accepted all year round  Self-Funded PhD Students Only

About the Project

Households are responsible for about 40 to 50 percent of total food waste. Reduction of household food waste would save the global economy over £190 billion and significantly reduce carbon emissions. In this project, a low-cost, efficient system will be developed by combining new sensor technology and advanced artificial intelligence (AI) software on mobile devices. Most existing works on AI-enabled food waste reduction are mainly for retailers.

The proposal here focuses on domestic household food waste. The basic idea is to attach a cheap, AI-enabled lightweight electronic device to a user's fridge that can detect whether food is going bad and the “best before” date. AI-based software on smartphones will create smart recipes and shopping lists.

The proposed project holds great potential for a low-cost solution to reduce household food waste. It is expected the candidate who is interested in this project has a Master's degree in Electronic and Electrical Engineering and BEng degree in Electronic and Electrical Engineering with upper second or first class.

Research journey

Doctoral research programmes (PhDs) take a proud place in the world-class research environment and community at Brunel. PhD students are recognised and valued by their supervisors as an essential part of their departments and a key component of the university's overall strategy to develop and deliver world-class research.

A PhD programme is expected to take 3 years full-time or 6 years part-time, with intakes starting in January, April or October.

The general University entrance requirement for registration for a research degree is normally a First or Upper Second Class Honours degree (1st or 2:1) or an international equivalent. A Masters degree is a welcome, but not required, qualification for entry.
