Mexico City generates 12 thousand tons of Municipal Solid Waste (MSW) per day, which places it as one of the cities that produces the most MSW in the world. However, the treatments used in the city are not enough for recycling materials and organics valorization of at least 45% of the MSW, which is the minimum for a medium-high-income city. To put in a global context the deficiency in Municipal Solid Waste Management (MSWM) in Mexico City and evaluate the policies that have been implemented thus far, Wasteaware benchmark Indicators for Integrated Sustainable Waste Management (ISWM) were used to obtain a desired profile for the comprehensive MSWM in Mexico City. The Wasteaware Benchmark Indicators have been tested in more than 50 cities around the world. The results showed that in Mexico City, certain aspects of governance present the most considerable delay and, at the same time, that there are certain areas of opportunity to improve the efficiency of MSWM in its physical aspects, such as collection systems or treatment services.

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.

This research aims to compare, from a technical and financial perspective, the application of biological (methane-capture) and thermal (incineration) treatments of waste in Mexico City in order to generate clean energy. For each alternative, pessimist (50%), realistic (80%), and optimistic (100%) scenarios were considered in terms of the efficiency collection rates of methane and the efficiency of the capacity conversion factor for incineration. For the methane project, the LandGEM model was used to evaluate the potential generation of methane. In order to calculate the electricity output that could be generated through incineration, we relied on two key factors: the total amount of heat that could be generated by burning the waste and the average level of moisture in the waste material. The evaluation resulted in an annual energy generation of 206.09 GWh for methane and 4183.39 GWh for incineration, both in the realistic scenario. Both projects reported positive financial indicators with a discount rate of 12%. Incineration resulted in a net present value of USD 706,377,303 and an internal rate of return of 23% versus USD 4,975,369 and 24% for the methane project. However, the incineration project only became feasible by omitting financing. Incineration resulted in a payback period that was lower by a ratio of 2:1 compared to methane, but the levelized cost of energy resulted in higher figures (USD 216.92). The aim of these findings is to support the decision-making process for the creation and implementation of sustainable energy strategies based on circular economy principles in Mexico and other similar regions across the globe.

This manuscript presents the development and testing of a novel model designed to help organizations, particularly small and medium-sized enterprises (SMEs), address the challenges of integrating new technologies within the frameworks of Industry 4.0 and 5.0. The proposed model is a metamodel that evaluates organizational and contextual vulnerabilities concerning both existing technologies and potential external technologies under consideration for adoption. It synthesizes three foundational frameworks: the Viable System Model (VSM), the principles of viable and sustainable systems, and the Technology, Organization, and Environment (TOE) Model. The findings demonstrate the practical applicability of this model in an SME context, showcasing its ability to facilitate the gradual and sustainable adoption of new technologies. By aligning business needs with technological solutions and leveraging insights from computer science and organizational cybernetics, the model adapts to varying levels of technological adoption, integrating organizational dynamics and business evolution to support the implementation of emerging technologies.

The purpose of this research is to show the way in which the integrated coastal management concept in Mexican coastal policy has had an impact on inter-institutional integration. In addition, the influence of local participation on the formation and activation of clean beaches committees integrated by the government, the private sector, and the society is studied. Due to the need for regional studies to evaluate this policy, it is considered Puerto Escondido as an example of change, based on the modifications made to the Mexican coastal policy. The soft systems methodology was used to integrate the vision of the clean beaches committees in a diagnosis. As a result, it is observed that coastal policy is moving towards the government and society integration. However, there is still a need for mechanisms to increase social participation. This work is limited to interpret the perspective of the involved clean beaches committees.
