“…The squares in dotted lines in Figure 1 indicate the activities carried out by the inhabitants. Since the separation of all MSWs has not yet been achieved, a part of them is collected mixed; it is shown in the figure that there are two different types of storage, mixed and buried [10]. In Mexico City, there are 1888 colonies or towns distributed in the 16 municipalities that make up the city, and each of them is served by a collection route.…”

“…The management of MSW is a challenge for the mayors in charge of the collection due to traffic density. According to current environmental regulations, the city government is in charge of the treatment and final disposal of the MSW for the amount generated and the lack of adequate areas within its territory [10]. Three different groups carry out the integral management of the MSW in Mexico City: the public cleaning service that performs the sweeping, collection, transport, and final disposal and treatment; the informal workers that carry out the manual separation of the MSW for recycling; and the private companies in charge of the industrial collection and recycling centers [9].…”

With 19 million inhabitants, Mexico City is the most populated agglomeration in Latin America, concentrating 30% of the national population. More than 61% of municipal solid waste (MSW) is sent to landfills, and 13% of MSW is recovered by Informal Sector Recyclers (ISRs) for recycling, which is the most crucial treatment option in the city. This article adopts a systemic approach to addressing the problem of the operationalization of relationships between ISRs and public services in Mexico City to design a recursive organizational structure with the identification of the critical roles and functions of management and governance in multi-level and multi-stakeholder relationships to integrate ISRs into MSW management. Using the Viable System Model (VSM) recursive structure to propose functional organizational structures in Mexico City is a new route for the study and application of systemic thinking in ISR integration. The VSM of the recycling system in Mexico City considers the recycling activities and characteristics of the territory at each recursion level. The authorities of the corresponding hierarchical level, who have sufficient knowledge of the physical and socioeconomic characteristics of the territory, are responsible for the design and operations.

“…Managing solid waste presents significant challenges for local governments in developing countries. Despite increasing volumes of solid waste, the majority of these countries lack adequate labor, money, equipment, knowledge, public services and other resources to manage waste in an environmentally safe manner [1]. A study of global MSWM found that service coverage was poor in low-income nations, and that in middle income countries there was a significant volume of garbage in open-dump sites with little or no environmental protection [2].…”

“…Wasteaware indicators can be applied in any city to assess MSWM performance. Galicia et al applied the indicator to obtain a desired profile for comprehensive MSWM in Mexico City which helped in addressing the weaknesses and strengths of its MSWM [1]. Azevedo et al [17] applied WABIs to case studies to do cross-case analysis to find drivers and governance strategies and for feasibility discussions and improvement possibilities.…”

Utilizing Wasteaware Benchmark Indicators to Improve Municipal Solid Waste Management in Northern Thailand

et al. 2023

Primarily responsible for waste collection and disposal, local governments in northern Thailand face significant obstacles in managing waste. Mixing infectious, hazardous and general waste, over-utilizing incinerators and implementing environmentally improper disposal methods all contribute to burgeoning volumes of waste with adverse environmental and health impacts. The objectives of this study are to use the Wasteaware benchmark indicators (WABIs) to assess the effectiveness and sustainability of the waste management of Wiengthoeng Sub-district Municipality (WSM), to identify advantages and disadvantages of its system and offer fact-based recommendations for improvement. Pertinent data was obtained through interviews of governmental authorities, community members and private sector employees between October, 2020 and May, 2021 using designed questionnaires and through review of official governmental records. It was found that with the help of village leaders, increased public participation in MSWM and working with local governments resulted in more widespread involvement in the 3Rs practices. Economic measures facilitated the objectives. Assessing ‘pay-as-you-throw’ fees resulted in a focus on lowering household costs through waste separation and reduction. The financial benefits of the program were not significant, but the source waste required for final disposal was reduced. The findings suggest that to increase the sustainability of municipal solid waste management, source reduction and segregation should be promoted to minimize the volume of refuse sent to landfills. Source reduction and collaboration between residents and village leaders can provide more long-term benefits than positive short-term economic impacts. Moreover, to improve the sustainability of its physical assets, WSM must better address the environmental impact of waste treatment and disposal.

“…Global population growth, economic development and urbanization have led to an increase in resource consumption and, consequently, in waste production, the management of such waste being a universally important issue [1]. As an example, 2010 million tons of municipal solid waste were generated worldwide in 2016, and at least 33% was inadequately managed [2]. In 2050, waste generation is expected to increase to 3400 million tons if no change occurs [3].…”

Over the last several years, the models for organic waste management have changed to implement circular economy in the productive cycle. In this context, new scenarios have emerged, where the management of different organic waste streams by composting is conducted with decentralized models that manage organic wastes in a more local way. However, in these new models, the standardization of the process control and of the end-product characteristics is necessary to guarantee the quality and agronomic value of the compost obtained, avoiding potential risks for human health and the environment. Thus, the aim of this work was to study two different scenarios of community composting of the organic fraction of municipal solid waste separately collected in order to guarantee the effectiveness and reproducibility of the composting processes and the quality of the composts obtained. For this, the development of the process and the characteristics of the composts at agronomic, hygienic–sanitary and environmental levels were assessed in real conditions and during three cycles of the process. The results obtained show high similarity among the different composting cycles, indicating an important degree of reproducibility among the processes. In addition, the composts obtained showed a good sanitary quality, absence of phytotoxicity and low contents of potentially toxic elements, which guarantee their use in agriculture without posing any risk to human health and to the environment.
