Waste Food

Food waste is a relevant global problem due to its consequences on food security, economy, and environmental sustainability. This study focuses, in detail, on finding the main motivation for food waste among the young and the principal actions to prevent it. The paper focuses on Italian reality, since Western countries are partly accountable for wasting large amounts of food. What is more, the focus has been shifted specifically on to the youths and young adults, as they are the portion of the population that are most inclined to waste food. Data were collected using a questionnaire survey performed on a sample of n = 904 Italian consumers. In line with previous research, the results of this study confirm that avoidable food waste comes from three main behavioural antecedents: over preparation, excessive purchase, and inappropriate conservation. The research shows that food waste cannot be reduced by just one-way from the consumers; rather, it goes both ways, between consumers and retailers. Therefore, only holding the consumers accountable and expecting them to solve it will not solve the problem of food waste; marketing and retailers should also consider ethics when it comes to food distribution.

Waste Food

Food production and consumption have remarkable negative environmental effects, in particular food waste. Food waste occurs throughout the entire food system, but households make the largest contribution. Reducing unnecessary waste of food represents a crucial step toward overcoming global issues of food waste, hunger, and climate change. Identifying barriers in reducing food waste is important not only to government and policymakers, but also to food producers, retailers, and marketers. Therefore, the objective of this research was to find out how consumer behavior in daily food provisioning affects food waste. An online survey was set up to question Dutch consumers (partly) in charge of the household’s food management. A total of 211 consumers participated in answering questions on household composition, food management behavior (e.g., food purchase planning) and food waste awareness (i.e., concern about wasting food and intention not to waste food). Results show that purchase behavior in-store was the main driver of food waste. Specifically, participants indicated that buying more food than needed often had led to food waste. In addition, intention not to waste food acted as a moderator in the relationship between planning behavior and food waste. Age appears to have a diminishing impact on wasting food.

Abstract The objective of this study was to determine methane yields (MY) of organic wastes in biogasification facilities according to the mixing ratio of food waste/food waste leachate and sewage sludge. One biogasification facility that treated sewage sludge only was compared with three biogasification facilities treating sewage sludge and food waste. The theoretical MY was derived based on analyses of carbohydrate, fat, and protein to examine the efficiency of the biogasification facility. The average actual MY was 0.424 Sm3CH4/kg volatile solids, which corresponded to 83.7% of theoretical MY. In the case of combined anaerobic digestion (CD) mixing with food waste/food waste leachate, inhibitory factors (volatile fatty acids [VFAs], total nitrogen [TN], and organic matter contents) showed the tendency to have relatively higher values in CD facilities than in the biogasification facility treating sewage sludge only. Mean concentrations of VFAs and TN in the anaerobic digester effluent, and the organic loading rate were 406 mg/L, 3,721 mg/L, and 1.62 kg volatile solids/m3 day, respectively. The influence of anaerobic digester effluent was in charge of 10% within the influent environmental loading rate from the sewage treatment plants associated with the biogasification facilities. Analyses of the microbial community showed that a remarkable change in the structure of methanogens was directly related to different MY in each plant. In particular, Methanoculleus and Methanosaeta increased with an increasing ratio of food waste/food waste leachate to sludge, while Methanococcus and Methanosarcina decreased. In conclusion, CD showed steady operational conditions and high efficiency of MY by injecting food waste/food waste leachate into the anaerobic digester. It met the current criteria for integrated treatment of organic waste in biogasification facilities in South Korea.

Waste Food

Each year around 1.3 billion tons of food goes to trash out of which 22 million pounds is generated from educational institutions. The purpose of this study is to understand the food waste pattern among college students to help minimize waste. The focus is on two food categories - deli and desserts to understand the influence of portion size on plate waste. The data is collected at a dining hall at a large state university in Midwest. Waste audit is conducted using waste stream analysis, which is the gold standard to measure waste. Food waste was collected, segregated, and weighed at the source, which leaves no space for mistake in waste assessment. Results reveal that the size of the served portion does not positively impact the amount of overall food waste. The study is unique as it is the first to provide insight on the influence of relaxed environment on food waste.

With resources becoming scarcer, waste of food is something to be avoided. Food waste must be minimized by using various ways to avoid waste in terms of food loss and food waste. In Indonesia itself, without realizing it, the issue of leftover food becomes very big. According to the Head of Representative of the United Nations Food Agency (FAO), Mark Smulders, of the approximately 1.3 trillion tons of food that was lost or wasted, Indonesia contributed around 13 million tons of food waste (food loss and food waste). This study will explore Generation Z's level of awareness of leftover food in Indonesia, especially in the Tangerang and surrounding areas. This research is exploratory in nature. The method is used to research something (which attracts attention) that is not yet known, not understood, or not well recognized. The date is collected using questionnaire that were distributed to respondents, namely Generation Z in Tangerang and its surrounding areas. From the results of data processing and tests carried out in this study, it can be concluded that the current awareness of Generation Z on the issue of leftover food must be raised, because the issue of leftover food itself is one of the issues of environmental preservation. The level of awareness of the issue of leftover food from Generation Z as the next generation must be increased, because only less than half of respondents are aware of this issue of leftovers.
