“…During the waste incineration, the acidification potential will be increased due to converting the sulfur and nitrogen content of incinerated waste to acidic gases (SOx and NOx) (Khandelwal et al., 2019). An LCA study reported that the NOx emission had a major contribution because of characteristic properties of MSW such as the presence of mineral fertilizers (Rana, Ganguly, & Gupta, 2019). The landfilling and composting processes have also potential to emissions acidic gases like NOx and NH 3 and increase the acidification potential.…”

Life cycle assessment was used to estimate the environmental impact of different municipal solid waste management strategies. Four scenarios (S1–S4) were considered, and the life cycle inventory of each scenario was performed using the integrated waste management (IWM) model. Scenario S1 in which all wastes are landfilled without processing and recovery of gas showed the highest negative impact on the environment. In scenario S2, where the organic portion of the waste is composted the environmental burden is greatly reduced compared to the first scenario. Scenarios S3 and S4, which are based on recycling and generation of energy, have a low environmental burden on the environment in addition to energy generation and conservation of nonrenewable resources. Therefore, increasing the use of waste processing and recovery options like composting, recycling, and energy generation base strategies is extremely recommended to reduce the adverse environmental impact of landfills.

“…In Panchkula, India, research conducted with SimaPro 8.3 determined the impact of MSWM scenarios. Among the proposed alternative scenarios, the combination of recycling, composting and sanitary landfill showed lower environmental impacts, with significant environmental savings achieved through energy recovery (Rana et al, 2019). In Hangzhou, China, using GaBi 8.0 software, a study found that incineration is better for the environment than landfill, whereas SC of recyclable waste can reduce the negative effects on the environment.…”

Application of a life cycle assessment for assessing municipal solid waste management systems in Bolivia in an international cooperative framework

Using a life cycle assessment (LCA) to evaluate municipal solid waste management (MSWM) systems is strongly recommended and the approach has been used in high-income contexts. However, stakeholders in low to middle income countries are not aware of the potential of this approach, mainly due to a lack of financial resources and technical ability. The present work introduces a LCA of MSWM system scenarios into a developing city using an academic licence for the LCA software that is available for use exclusively by researchers. The MSWM system in place in 2018 in La Paz (Bolivia) was assessed according to seven scenarios. The novelty of the research is twofold: the use of LCA academic licensing in a low to middle income region where LCA is unknown as planning tool; and discussing the potential of the approach in conjunction with local and international stakeholders with a view to starting MSWM projects. The results of the analysis allow for the consideration of energy recovery and materials recycling as the main methods by which the environmental impact of MSW can be reduced, as has also been reported by other LCA studies conducted with full licensing of the relevant software. Moreover, the research is the basis for cooperative development projects that will adopt the LCA approach as the main assessment tool. The study discusses the importance of cooperation between universities and local governments for implementing new strategies for MSWM assessment and planning. The research is a contribution towards improving technical knowledge in developing countries for boosting sustainable development.

“…Another implication of the study is that it will make the Kabul multiplicity recognize the importance of recycling approaches from results obtained based on environmental and economic assessments, which has dramatically diminished GHG emissions and costs through recycling materials. Recycling of waste materials can make an important contribution by reducing environmental impacts and generating revenues in some developing countries [33,43]. Similarly, findings obtained for source-separated systems can be expected to encourage officials to launch this program and develop effective policies.…”

Analyzing Waste Management System Alternatives for Kabul City, Afghanistan: Considering Social, Environmental, and Economic Aspects

2020

Our earlier work identified social issues of stakeholders who are highly exposed to poor social performance in the current waste management system (WMS) of Kabul city, Afghanistan. The present work builds on earlier findings to elaborate four alternative scenarios with better social outcomes. For each scenario of the current system, greenhouse gas (GHG) and economic assessments were conducted. Results show that Scenario 2, considering increase waste collection coverage, recycling, unsanitary landfilling, and integration of informal workers, was found as the best alternative. Scenario 3, which added a source-separated system to Scenario 2, was the second-best alternative. These two scenarios address social issues and can reduce GHG emissions, save costs, and provide more jobs than the current system. In contrast, the absence of recycling in Scenario 1, and the conversion of unsanitary landfill into sanitary landfill in scenario 4 result in higher costs and GHG emissions, even though they deal with social issues and generate higher jobs to the existing waste management practice.
