“…Furthermore, Koester et al (2018) concluded that costs incurred by the measure itself, namely the costs for implementing a measure, are rarely considered. Cristóbal et al (2018) further conclude there is only "limited knowledge on the evaluation of food waste prevention and management strategies including both economic and environmental dimensions" and that data on performance of measures is scarce.…”

“…To our best knowledge, no reviews currently exist assessing the extent to which ecological impacts, monetary costs or savings, and efficiency of food waste measures are considered. Several authors have however stressed that, in case monetary aspects are taken into account, these tend to be restricted to the costs embodied in the food itself (based on for example retail prices), whereas disposal related costs are neglected (Rutten et al, 2013;Teuber and Jensen, 2016;Cristóbal et al, 2018;Koester et al, 2018). Furthermore, Koester et al (2018) concluded that costs incurred by the measure itself, namely the costs for implementing a measure, are rarely considered.…”

The last few years, a lot of measures addressing food waste have been proposed and implemented. Recent literature reviews call for more evidence on the effectiveness or food waste reduction potential of these measures. Furthermore, very few information is available on the extent to which food waste measures have been evaluated based on their economic, environmental and social performance. This review closes this knowledge gap by looking at the methodologies currently used in literature to evaluate food waste prevention measures, using a pre-defined assessment framework with quantitative evaluation criteria. In total, evaluations were examined for 25 implemented measures with measured outcomes and 23 proposed measures with projected outcomes. The paper concludes that there is a great variety in how an evaluation is performed. Additionally, in many cases, economic, environmental, or social assessments are incomplete or missing, and efficiency is only seldom calculated. This is particularly true for implemented measures whereas proposed measures with projected outcomes tend to have a more thorough evaluation. This hampers practitioners and decision-makers to see which measures have worked in the past, and which ones to prioritize in the future. Moreover, more complete information on the effectiveness and efficiency of measures would make incentives for reducing food waste at various levels along the food chain more visible. At European level, work is ongoing on the development of a reporting framework to evaluate food waste actions. This paper complements these efforts by providing an overview of the current gaps in evaluation methodologies found in literature regarding food waste prevention measures within EU and beyond.

“…The stakeholders showed a great interest in pointing out all sorts of difficulties that farmers, wholesalers, and supermarkets, as well as social entities, face when improving redistribution in the metropolitan region. Although the issue of food redistribution, as an acceptable alternative to food waste prevention and reduction, has been treated extensively in the literature [49,72,76,87,88], no previous study has referred to such difficulties (see Table 6).…”

A Sum of Incidentals or a Structural Problem? The True Nature of Food Waste in the Metropolitan Region of Barcelona

et al. 2018

Addressing the generation of food waste is a major challenge nowadays. An increasing interest in studying food waste generation has emerged over the last decade. However, little attention has been devoted to understanding the root of the problem by carrying out a whole-supply-chain analysis and applying multidimensional approaches. The aim of this paper was to identify the causes of food waste in the metropolitan region of Barcelona along the food supply chain, considering the relevant stakeholders’ perceptions. Moreover, we examined the circumstantial or structural nature of the identified causes. We conducted a qualitative study consisting of 24 in-depth interviews of key stakeholders in the region along the food supply chain from October 2014 to January 2015. The interviews were analyzed by content analysis, and the main results are presented here. We used a conceptual framework that differentiates among micro, meso, and macro causes to disentangle the nature of the causes. The results from this study show the great interest of regional stakeholders in the issue of the generation of food waste and provide a complete map of the causes of food waste in the metropolitan region. From our study, we advocate that food waste is not only a sum of incidentals but it a structural problem.

“…Cristóbal et al in Europe addressed the situation where a decision maker has to design a food waste prevention programme considering the limited economic resources and the results highlighted that to set the targets at the level of environmental impact is of importance instead of setting the targets at the level of avoided food waste generation (in mass) when FW prevention strategy requires planning [16]. While in China, Wen et al studied a case on evaluation of a sensor-based Internet of Things (IoT) network technology for restaurant food waste management.…”

Abstract.Since a large amount of food supplying is provided as a basic line measuring increasing residents' life standard, food waste has become progressively numeral considerable. Much attention has been drawn to this problem. This work gave an overview on latest researches about anaerobic digestion, composting, generalized management and other developments on management of food waste. Different technologies were introduced and evaluated. Further views on future research in such a field were proposed. IntroductionFood waste (FW) is composed of household food waste, food-processing waste, canteen and restaurant waste, which is one of the components of municipal solid waste [1]. The accumulation of FW cannot be neglected because of tremendous environmental and sanitary problems with it. FW amount is estimated to quickly increase from 2.78 billion tons to 4.16 billion tons in Asian countries by 2025[1]. About 1.3billion tons of food, fully one-third of all food produced is lost along the food supply chain every year [7]. While economy is still accelerated, FW grows larger at the same time. However, it is significant to see that FW management also takes an important role in the renewable energy and sustainable development for values like Biomethane potential(BMP) of FW. With rising attention being moved on this field, technologies developments for this have been made continually.Anaerobic digestion (AD) has always been the hot research trend for its relatively costeffectiveness, renewable energy production and waste treatment of high-moisture and energy-rich material [2]. During AD process, biomass and organic fraction of municipal solid waste (OFMSW) can be converted into combustible biogas (mainly methane, and other gases like hydrogen and hydrogen sulfide) [2]. Parameters such as methane yield and volatile solids reduction or so were used to assess experiment performance. In order to enhance methane generation performance, various aspects of AD were researched. Additive supplementation, operational alternations, parameters optimization and microbial actions have been discussed by researchers. In addition to AD, composting, co-pyrolysis and other FW managements pathways also have been conducted to research results. At the same time, investigations and sorting systems were made for governments to implement better decisions on FW management. This paper aims to critically give an overview on latest research progress and novel developments of FW management in 2018. Further views on future research needs in such a field were proposed simultaneously.
