My research in sustainability are in two key areas: Food Wastes and Supply Chain for Circular Economy.
Food Waste

It is estimated that as much as 50% of global food may be lost or wasted before and after it reaches the consumer. This includes losses and wastes resulting from inefficiencies in harvesting, transport, storage and packaging, food processing, wholesale, retail, preparation and consumption.

Reducing waste in food supply chain and in our homes will have many direct and indirect benefits to the environment, to individuals and to the companies involved in food supply chains. An obvious benefit of reducing food waste is that it will save food that would otherwise be lost thereby bringing about significant cost savings to people and to companies. This means that as more and more food is saved from going to waste, we will progressively need less food to be grown or produced. This will lead to reduction in the resources required for food production such as land, water, equipment, transportation and distribution thereby reducing greenhouse gas emissions. The knock-on effect of these, is that the need for landfilling would be reduced which would in turn reduce greenhouse gas emissions. And generally, all these would help to improve food security.

My research interest in this area focuses on three targets - final consumers, hospitality industry and retailers. Some of the research topics can be seen on the right side of this web page.

Supply Chain for Circular Economy

The main idea of circular economy is that linear (or open) production systems – in which raw materials are extracted, utilised to manufacture products that are used by consumers and then disposed of as waste – should be replaced by circular production systems that reuse the products thereby closing the material loop (CE reference below).

There are strong arguments for businesses to transition to the circular model not only the resource efficiency and sustainability aspects but also the exposure to risks such as resource price volatility and supply disruptions that are inherent in the linear model (CE reference below).

It is recognised that supply chains and supply chain management plays a central role in enabling circular production systems and there are huge opportunities for research into methodologies, systems and techniques for reconfiguring and optimising the forward and reverse material flows to facilitate reuse and remanufacturing.

I am interested in collaborative research in this area and also very keen for PhD students that are would like to carry out doctoral research in this area.
