Managing municipal solid waste correctly is critical to the success of a society. Many regions and countries in the world are behind others in the context of solid waste management. In order to compare three such regions within this context, a meta-analysis was conducted in order to develop a decision matrix. Within this decision matrix, the United States, Europe, and Asia were compared to determine which region is managing municipal solid waste the best. This research design allowed for compiling information from many sources to increase the accuracy of data used in the justifications for the decision matrix. Purposive sampling was used to select and evaluate sources that discuss solid waste management to discern which region’s processes are most favorable in many parameters. The decision matrix consists of nine parameters: main management techniques; finances; landfill taxes; jobs created; waste generation; waste composition; waste storage, collection, and transportation; energy recovery; and environmental health. Each was scored on a scale from zero to ten, ten being the best score and zero being the worst. The final score from the decision matrix suggested that Europe had the most favorable municipal solid waste management (MSWM) system, and the United States had a notably close yet lower score. Asia had the lowest score that was hardly comparable to the other two regions.

Currently, the amount of solid waste is increasing in the world, especially in developing countries. Although Solid Waste Management (SWM) involves and collaborates with many stakeholders, management is still flawed. SWM in the urban and suburbs of Phnom Penh has encountered a number of obstacles and challenges. Seeing these problems, the government has decided to reform the solid waste management in Phnom Penh in 2019. After the reform, the provision of waste collection, transportation, and cleaning services in urban and peri-urban has changed significantly, while the urban and peri-urban receive collection services 95% and 80%, respectively. To be more precise one study on the current situation of SWM in urban and peri-urban Phnom Penh was conducted to understand the current situation and to identify challenges of SWM for the urban and the peri-urban in Phnom Penh. Two kinds of data were collected 1) preliminary data was collected from interviewing people in target areas by using structured questionnaires, and 2) secondary data was obtained from existing various sources. 330 respondents were selected with qualitative and quantitative analysis by using SPPS 28.0.1.1 and Microsoft Excel 2019. People use plastic bags instead of bins, triggers, and bags to store the waste.79.5% of the people are willing to pay the collection fee. It was found that the situation of SWM is better, however, the collection time is still blurred. SWM in Phnom Penh has faced four main challenges: financial, road infrastructure, landfill, and people's participation. SWM in urban and peri-urban, still have some problems such as the packaging and storage of the waste. and the problem of scavengers tearing the waste bags makes the garbage clutter.
