“…The amount of food waste in the EU reached 88 million tons per year, which is equivalent to 173 kilograms per person (Stenmarck et al, 2016). Food waste has become the largest portion of post-harvest loss (PHL) and waste in China, and 17-18 million tons of food are wasted in the catering industry alone in China annually (Xu et al, 2020).…”

Economic development has improved people’s daily diets in China, but food waste has increased significantly. China faces severe natural resource constraints, and reducing food waste is important for ensuring national food security. Based on 1634 survey samples from 28 provinces in China, this study assessed food waste in rural China and empirically analyzed the main factors affecting rural household food waste. The results showed that, on average, 1.67% of food is wasted per household each day in rural China. Food waste is greater in economically developed areas, such as East China. Empirical analysis showed that cooking utensils, preparing the right amount of food, religious beliefs, number of family members, average weight of family members, percentage of purchased grain in the total food consumption in 1 year, and total grain output are significantly related to rural household food waste.

“…Second, most studies have focused on food waste in developed countries or food waste in the catering industry have given insufficient attention to rural household food waste (e.g. Liu and Chen, 2020;Xu et al, 2020). Hence, previous results on food waste may be unreliable.…”

“…The existing literature suggests that human decision-making is highly complicated. The subjective and objective characteristics, including demographic and economic factors [18], diet culture [6,36], social rules [37], perceptions [19], attitudes [38,39], dining factors [40], information intervention [9,11], and other factors can affect food-wasting behavior. However, it was found that the impact of the above-listed factors is not consistent under different circumstances.…”

“…Although studies on food wastage are now abundant, previous studies are primarily about developed countries [5]. Similar studies in emerging countries, such as China, are relatively scarce [40]. China now ranks second worldwide in terms of GDP, and food wastage is becoming a growing concern in China with its rapid economic progress [4].…”

Are the Slimmer More Wasteful? The Correlation between Body Mass Index and Food Wastage among Chinese Youth

et al. 2022

With the economic growth and living standard improvement, food waste has become increasingly common among Chinese youth. To test whether body size affects the food waste performance of youth, we examined university students as representative of the Chinese youth and conducted a large-sample survey in 29 universities across 29 provinces. Based on 9192 questionnaires collected from Chinese college canteens, we found that body size was correlated with food waste. The smaller the body mass index (BMI) value, the higher the likelihood of plate waste, the higher the amount of waste, and the higher the ratio of food waste. Heterogeneity analyses revealed that BMI exerted a more significant impact on males than females, as well as a more substantial impact on northerners than southerners. Robust tests using other proxies to measure body size, robust regressions based on the new adjusted samples, and robust tests with an instrumental variable to overcome the endogenous issue suggested that the slimmer participants tended to be more wasteful. Hence, this study confirms that the slimmer youth tend to leave plate waste and waste more food per capita per meal. This study is the first attempt to analyze food wastage from the perspective of BMI in China to our best knowledge, and it provides a unique viewpoint for understanding young people’s food wastage.

“…Energies 2021, 14, 5907 2 of 16 Internationally, researches on the phenomenon of food waste in the food supply chain have their own focuses. In the consumption link, scholars have focused on waste on the dining table, that is, food surplus on the plate [11,12]. In developed countries, researches mainly focus on restaurants [13], households [14], hospitals [15], and schools [16].…”

Food waste has caused double waste of resources in the food itself and the food supply chain of production, transportation, cooking, and processing, resulting in unnecessary greenhouse gas emissions and economic losses. This paper first conducted the quantification of students’ food waste and the collection of canteens operation data in the three canteens at Taiyuan University of Technology (China) in 2019 through the weighing method and interview. Then an integration of Life Cycle Assessment and Life Cycle Costing was used to quantify the impact of food waste in university canteens on the environment and costs. The study found that the total amount of food waste in the university canteens with 22,000 students was 246.75 t/a, the carbon footprint caused by food waste was 539.28 t CO2-eq, and the cost was 4,729,900 yuan. Most of the impact of canteen meals on the environment comes from the use of energy in food cooking and the consumption of animal food types. The innovative integration of life cycle cost calculations highlights the key role of the labor required for cooking. The research results answer the basic scientific questions of how much food is wasted in the university canteens, and the carbon emissions and cost ratios of these wasted food in all links of the supply chain. The research results can provide a policy-making basis and data support for reducing food waste in universities and realizing carbon emission reduction in university canteens.
