Repositioning Animal By-products into Food Loss and Waste: From Environmental and Nutritional Perspective

Food loss and waste (FLW) has become a significant environmental issue in recent years. However, definitions of FLW remain a subject of ongoing debate which lead to many foods not being classified as FLW due to regional disparities, customs, and religious practices. Chicken by-products are considered delicious ingredients in many countries, but not include the UK. Instead, they are rendered to produce poultry meal or biofuel, or processed into petfood. Only 1% of total chicken by-products are consumed by people, which is a great waste saying from food perspective. Moreover, the nutritional value of chicken by-products is not significantly lower than that of commonly consumed chicken meat. Additionally, the by-products contain higher levels of trace elements such as iron, zinc, and copper which are all essential micronutrients for the human body, which play a vital role in human health. This is a waste as well saying from nutritional perspective.


I graduated from Qingdao University in 2018 with dual degrees in Bachelor of Science and Bachelor of Management. In 2021, I earned a Master's degree in Engineering from the Ocean University of China. During my master's program, I focused on utilising a novel low-intensity electric field for the co-extraction of proteins and lipids from Greenland Halibut by-products.

Currently, my Ph.D. research centres on FLW produced from poultry industry in the UK, figuring out the most environmentally friendly option for poultry by-products disposal, finding out suitable methods for cooking poultry by-products in an environmental and nutritional way, trying to change people's perspective of poultry by-products, and finally build a novel framework focusing on the classification and definition of poultry by-products on a global scale.
