“…Moreover, approximately 33% of the world’s edible food is lost or wasted, approximately 56% of which occurs in developed countries [113]. Global food waste is not only related to the reduction in supply but also has a direct impact on the environment, such as greenhouse gas emissions, surface and underground water consumption, and land occupation [124]. Given the above findings, plastic use and food wastage should be afforded sufficient attention in the future, with a focus on usage behavior avoidance, usage behavior reduction, and plastic recycling behavior, as well as food saving and waste reduction behavior.…”

Since the theory of planned behavior (TPB) was proposed by Ajzen in 1985, it has attracted extensive interest and been widely applied worldwide. Although an increasing number of studies have employed the TPB in the domain of environmental science, there have been no attempts to retrospectively analyze existing articles. The current study aimed to holistically understand the application status of the TPB in environmental science from a knowledge domain visualization perspective. A total of 531 journal articles were obtained through the Scopus database to perform a bibliometric analysis and content analysis. The results showed that waste management, green consumption, climate and environment, saving and conservation, and sustainable transportation are the primary research topics; the United States (U.S.), Mainland China, the United Kingdom (UK), and Malaysia are the most productive countries/regions. Moreover, the cross-disciplinary situations, main source journals, and key articles were revealed. Furthermore, the extended factors, integrated theories, major methods, specific groups, and control variables of environmental science research using the TPB were elaborated and integrated into a comprehensive application framework. Constructive criticisms were ultimately discussed. The findings contribute in several ways to help relevant researchers learn about the application of TPB to environmental science and provide new insights and holistic references for further research on environment-related behavior.

“…Additionally, harvesting, storage, transportation and processing losses that are not avoidable with best available technologies and reasonable extra costs are also classified as unavoidable. Some authors do not impose a specific FLW definition losses (Beausang et al, 2017), and others propose their own definition according to the context of study (Barco et al, 2019;Chaboud and Daviron, 2017;Chaboud, 2017;Barth et al, 2019;Willersinn et al, 2017) without distinguishing between supply chain stages or FLW concepts.…”

PurposeThe purpose of this paper is to systematically review and critically examine food losses and waste quantification in supply chain, especially in studies that tackle all the supply chain activities in a real context.Design/methodology/approachThis work employed a systematic literature review methodology on the extant literature focusing on peer-reviewed journal articles published from 2000 to 2019.FindingsA systematic analysis of 117 articles reveals that downstream supply chains are studied to a greater extent than upstream supply chains, with an emphasis on consumer waste. The findings also highlight more than half of the articles focus on only one supply chain activity. In terms of the methodologies, surveys and modelling methods are the most used to measure food losses and wastes, adopt monetary, carbon emission and calorific metrics. This study highlights that while food losses and waste research remains a relevant field of study, it has yet to been fully explored.Research limitations/implicationsThe main limit is the adoption of a systematic review method for food losses and waste quantification in supply chain.Practical implicationsThe results suggest that supply chain managers should invest in acquiring more knowledge about food losses in the global network. Upstream supply chains should be more studied and integrated with the downstream supply chains. Using combined direct and indirect methods has the potential to deal with the contradictions of quantification, the lack of data and reduce losses over time and space.Originality/valueBased on this review as the first one focusing exclusively on quantification of food losses and waste in supply chain context, the authors develop an aspiring research agenda that proposes opportunities for future research.HeadingsWe analyse 117 studies addressing food losses and waste quantification.Downstream food supply chains are more studied than upstream food supply chains.Case studies of food supply chains in developed countries are more prolific.The main metric to quantify food losses and waste is weight.

“…Recently, food waste has received increasing interest from policymakers in various fields worldwide. There are enough studies that note that a reduction in FLW can positively influence food security and mitigation of climate change (Wunderlich & Martinez, 2018), and thus, studies carried out in countries with advanced economies have focused on quantifying and characterizing FLW (Broekmeulen & Van Donselaar, 2019), and related proposed quantification methodologies (Barco et al, 2019;Corrado et al, 2019), although this is an expensive process that countries with middle-and low-income economies cannot afford. Additionally, it is estimated that approximately one-third of the food for human consumption is lost or wasted from the farm to the table (Food and Agriculture Organization of the United Nations, 2011a).…”

An exploratory study of possible food waste risks in supermarket fruit and vegetable sections

2021

View full text Add to dashboard Cite

Food waste is an emerging issue in terms of food policy; the most common cause of fruit and vegetable waste at a retailer, in addition to excess stock and consumer behaviour, is the lack of employees certified in food handling. Fruits and vegetables require specific handling and storing to avoid waste. The objective of this work was to survey the employees of fruit and vegetable sections in supermarkets to understand their experience and the reasons they believe products are wasted. The results show that most employees have secondary educations; the average age of these employees is 33 with at least one year working for the company; and no significant correlation was found between age and seniority in the company. In comparison to international supermarkets, national supermarkets train their employees less. Employees perceived the best-selling fruits to be bananas, apples, papayas, melons and pineapples and the vegetables to be tomatoes, onions, green peppers (serrano), and potatoes, which are essential in Mexican cuisine, and their perceptions of best-selling produce were related to waste, probably due to the widespread availability of these types of produce. One of the strategies to avoid wasting fruits and vegetables in good condition is donating them to food banks.
