“…In recent years, municipal solid waste (MSW) management has become increasingly urgent in emerging countries due to economic growth, and the acceleration of consumption has caused an expansion in waste generation. The rise in waste creation has caused a severe shortage of landfills and higher costs for waste management [1]. MSW is also one of the public management aspects that plays a vital role in grasping opportunities and minimizing municipal and rural difficulties in relation to the negative aspects of increasing urbanization.…”

According to decision no. 491/QD-TTg signed in 2018 by the Vietnamese Prime Minister approving adjustments to the national strategy for the general management of solid waste until 2025 with a vision toward 2050, Vietnam has committed itself to move toward collecting, transporting, and treating 100% of non-household waste by 2025 and 85% of waste discharged by households by 2025. This paper aims to determine which is the best sustainable solid waste management system out of those that have been formulated by World Bank experts for Hanoi until 2030 for implementing the national strategy. The paper compares four distinct solid waste management enhancement alternatives, namely, “Improving the current system for waste collection and transportation”; “Reducing, reusing, and recycling waste at source”; “Mechanical–biological treatment (MBT) plants for classifying, composting, and refuse-derived fuel (RDF) for the cement industry”; and “MBT plants for classifying, composting, and RDF for waste-to-energy/incineration plants”. The comparison was made using an analytic hierarchy process. As a result, the research indicated that “MBT plants for classifying, composting, and RDF for waste-to-energy/incineration plants” has the highest ranking in terms of a sustainable solution for the municipal solid waste management system. Therefore, it should be applied for managing the current situation in Hanoi. At the same time, the sustainable development of the system must seek to decrease the waste-to-energy ratio continuously and significantly through the planned reuse of materials that can be recycled to industry. According to the literature, in major cities in Asia and Africa, development programs are moving toward waste-to-energy solutions. The EU’s circular innovation programs and action plan may be in the opposite direction to this trend.

“…Likewise, electricity prices, grid interconnection, fuel production, and high capital start-up cost may present financial barriers, thus necessitating the maintenance of valuable materials and products within a sustainable circular economy (European Parliament, 2017;Velenturf and Jopson, 2019). A guideline on separate waste collection was adopted with new waste regulations in July 2017 and is expected to increase the amount of reused or recycled waste and decrease the amount of illegal waste disposal (Tsydenova et al, 2018). Policy regulations and instruments, such as subsidies from the National Council of Science and Technology of Mexico that support participation in the Horizon 2020 program (European Commission, 2017), are needed to enable waste valorization through the implementation of environmental technologies.…”

“…Therefore, an energy transition from fossil fuel to renewable energy is urgent (Cancino et al, 2016). In this context, transitioning the waste management system to more sustainably harvest and provide bioenergy will allow Mexico to reduce the environmental impacts associated with the waste and energy sector (Tsydenova et al, 2018).…”

Environmental Assessment of Alternatives for Biowaste Treatment in Mexico City

This paper aims to determine the environmental performance of the current landfill gas management system (based on flaring) in Mexico City (Bordo Poniente) in comparison to the collection of biogas generated from solid waste through one of the most innovative technology implemented in Denmark (Aikan Technology), which produces biogas and digestate from waste. Two alternative scenarios are proposed in which the Aikan Technology is implemented in Bordo Poniente to replace the existing system (reference scenario) that involves landfilling inorganic waste and composting organic waste in Bordo Poniente with no biogas recovery. The biogas recovered through Aikan Technology is exploited to provide heat and electricity (Scenario 1) or biofuel for the transportation sector (Scenario 2). A comparative life cycle assessment (LCA) was performed to evaluate the environmental performances associated with all scenarios by evaluating the impact categories Climate Change, Fossil Depletion, and Cumulative Energy Demand. According to the waste capacity of Bordo Poniente, the implementation of the Aikan Technology would result in a total annual reduction of 0.14 and 0.08 Mt of CO 2 eq for Scenario 1 and Scenario 2, respectively. Scenario 1 was also the best performing scenario with respect to fossil depletion (−52 kg oil eq ton −1 of organic waste) and cumulative energy demand (−3,557 MJ ton −1 of organic waste). The implementation of Aikan Technology in Mexico City represents an important challenge and requires further research into its economic and political feasibility. When it comes to tackling global environmental problems, international agreements ascribe high importance to environmental technology transfer. This study represents a preliminary step in terms of environmental assessment and thus provides important information for policymakers attempting to achieve more sustainable management of solid waste in Mexico.

“…Currently, Mexico City needs to increase the MSW recycling rate, since most of its MSWs are send to private landfills in neighboring states [21]. For treatments with better efficiency than separation and compost plants, such as heat treatment, Tsydenova et al indicated the importance of introducing waste incineration is sustainable from the environmental, economic, and social aspects of waste that cannot be sent to organic treatments and/or recycled [23].…”

“…Indicator 6L is a measure of the institutional strength and coherence that exists between the different functions related to the MSWM, by reviewing the organizational structure, capacity and ability of inter-institutional cooperation as shown in Table 10. In 2017, Mexico City published official standards NADF-024-AMBT-2013 on the separation and recovery of Municipal Solid Waste (MSW) and on Special Management (SW), to increase the amount of collected recyclable materials and thereby decrease the quantity of landfilled material [23]. Through these instruments, it was the first entity in the country to establish the separation of MSW [56].…”

A Study and Factor Identification of Municipal Solid Waste Management in Mexico City

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.
