“…In Latin America and the Caribbean (LAC) countries, there is a growing interest in the research, promotion and implementation of various waste management alternatives, such as sorted waste collection, recycling and WtE approaches. Research and policy initiatives on sustainable and circular production models (SCPMs) prioritize bioenergy and biofuels as leading possibilities for the valorization of the organic fraction of municipal solid waste (OFMSW) such as FW ( Ulloa-Murillo et al, 2022 ). One of the major priorities in LAC was reflected in the circular economy (CE) and bioeconomy as the primary drivers of waste recovery and/or valorization.…”

“…Garcia-Peña et al (2011) studied the practicality of hydrogen (H 2 ) generation under batch circumstances using fruit and vegetable waste (FVW) supplied from local markets in the Mexican context and discovered that H 2 production from FVW is a novel and feasible energy technology. Research has noted that these countries have made progress in implementing public policies for integrated MSW management based on SCPMs (Duque-Acevedo et al, 2020a;Duque-Acevedo et al, 2020b;Ulloa-Murillo et al, 2022) enhanced the conversion of waste into valuable goods (organic amendments, animal feed, bioenergy and biofuels), contributing to the establishment of new markets (Schröder et al, 2020;Ulloa-Murillo et al, 2022). In Mexico, a study by Garca-Pea et al (2011) focused on the feasibility of using FVW from a food distribution market as a substrate for AD and discovered that pH control and nitrogen addition improved AD performance and co-digestion with meat residues allowed for better results (Garca-Pea et al, 2011).…”

The management and prevention of food losses and waste in low- and middle-income countries: A mini-review in the Africa region

2023

View full text Add to dashboard Cite

This mini-review analyses food losses and waste (FLW) management in low- and middle-income countries (LMICs) and identifies potential strategies to improve FLW management efficiency on the African continent. To achieve this aim, a search of grey and published scientific literature-case studies, feasibility studies, theses, peer-reviewed journals, governments and technical reports was performed. Food waste (FW) per capita in sub-Saharan Africa (SSA) was determined to be between 6 and 11 kg capita−1 year−1. Factors militating against FLW management include a lack of infrastructure, waste reduction and mandatory waste management plans, financial support for food redistribution programmes, awareness and a lack of knowledge of FW management and effective approaches. Poor recovery systems, a lack of incentives in FW recycling programmes, a lack of a regulatory and policy framework and institutional weaknesses as well as a lack of sufficient and appropriate education programmes to improve FW source separation and collection rates are all significant challenges in the African region, with negative consequences for the environment and public health. Except for fuel conversion and food scraps for digestion to recover energy, there is a huge potential for composting and using FW as a digestate, which could eventually lead to a reduction in the amount of FW being landfilled or incinerated. The study explores potential interventions to reduce amount of FLW and form a basis for future research in this field and improving FW management efficiency in LMCs, especially on the continent of Africa. It also provides information that could assist researchers, policymakers and decision-makers reduce amount of FLW, aid in the utilization of FW for energy production, and reduce greenhouse gas emissions in the continent, as well as support the achievement of other sustainable development goals, such as 12.3, which is particularly important in the context of the African continent, which is dependent on food imports.

“…The final sample included 81 studies for Spain and 9 for the Czech Republic. Then, from the CSV files with the metadata of the last samples obtained from Scopus, a scientometric analysis was carried out, one of the most widely used methods to evaluate the structure and evolution of scientific production ( de Sousa, 2021 ; Murillo et al, 2021 ; Ulloa-Murillo et al, 2022 ). Using VOSviewer, version 1.6.16, specialized software for scientific mapping ( Wang et al, 2021 ; Wong, 2018 ), keyword co-occurrence network with an overlay visualization was constructed.…”

Sustainable and circular production models, such as the circular economy and circular bioeconomy, have become key mechanisms to leave behind the traditional linear model of food production. Under this approach and considering the waste biomass potential available in Spain and the Czech Republic, the main objective of this study is to analyse the most relevant aspects of the generation, use and regulation of agricultural waste biomass (AWB) in both countries. For this purpose, a scientometric analysis and systematic review of published research in the Scopus database were carried out. A complementary analysis of AWB management policies and regulations was also part of the methodology. The results show that Spain has published almost twice as much research as the Czech Republic. Furthermore, 91% of the retrieved research prioritizes the characterization and estimation of the potential of more than 15 AWB types. Among the main ones are olive residues, horticultural residues and wheat straw, which are used for producing organic amendments, bioenergy and biofuels. The results confirm that the reduction and valorization of AWB is an issue that has become more important in the last 13 years, mainly due to the policies and strategies for circular economy and circular bioeconomy. With this in mind, this study provides relevant information for governments on the aspects that need to be improved to advance in the valorization of AWB. This study also provides guidance to farmers on the reduction and/or recovery alternatives that they can implement to move towards sustainable and circular agriculture.

“…Review studies on WM in developing countries’ context considered different levels such as regions, continents, nations, cities and communities to individuals. For instance, some studies covered WM in Asian developing countries (Ali and Sion, 2014; Dhokhikah and Trihadiningrum, 2012), in South Africa (Godfrey and Oelofse, 2017), in Latin America and the Caribbean (Ulloa-Murillo et al, 2022) and cities in developing countries (Guerrero et al, 2013; Wilson et al, 2013). Other studies have focused in their reviews on the assessment methods (i.e.…”

This review provides the history and current paradigms of waste management (WM) practices in developing nations during the last five decades. It explores the evolution of the challenges, complexities, and trends during this period. This paper, for the first time, presents an estimation of the amount of municipal solid waste (MSW) generated in developing nations in the last five decades based on the material flow analysis approach. Overall, the amount of MSW in developing countries has increased from about 0.64 billion Mt in 1970 to 2 billion Mt in 2019. This review demonstrates the importance of finding new WM approaches in developing nations in the context of formulating policies, strategies, and highlights the major trends that re-define WM in developing countries. It also aims to present the holistic changes in technology, economic and environmental feasibility aspects to attain an integrated sustainable WM system in developing countries. Specific focus on open-burning, open-dumping, informal recycling, food waste, plastic pollution, and waste collection with reference to Sustainable Development Goals are explained. Drivers for the way forward including circular economy are investigated.
