Analysis of Potential Methane Gas Emissions from Final Processing Site (TPA) Waste: Case Study at Namo Bintang TPA, Medan, North Sumatra

Global Warming and Greenhouse Gas Emissions: A Growing Concern

Global warming has become an increasingly serious issue in various parts of the world, with greenhouse gas (GHG) as one of the main causes that contribute to this phenomenon. Each country is now required to commit to reducing the GHG emissions produced and inventorying GHG and sources of gas formation. GHG emission inventory is an important step to understand how much emissions are produced in an area within a certain period of time. In the Indonesian context, one of the activities included in the National GHG Emission Inventory Program is to review GHG emissions from a solid waste pile managed at the Final Processing Site (TPA).

The Role of Waste in GHG Emissions

Waste piled up in the TPA is the main source of GHG emissions, especially methane gas (CH4) which is produced from the anaerobic decomposition process. The GHK emission inventory of the garbage pile in the TPA not only calculates the CH4 gas produced, but also strives to take into account the potential for reducing GHG emissions by utilizing the gas as an energy source. The estimated GHG emission potential in the TPA is carried out based on guidelines from the 2006 Guidelines (IPCC) intergovernmental panel (IPCC), which require data related to landfill activities, the amount of waste, and the composition of waste is discarded.

Case Study: TPA Namo Bintang, Medan, North Sumatra

TPA Namo Bintang, with an area of 176,392 m², functions as a final processing place for the people of Medan. Operating since 1987 with an open dumping system, this TPA is located in Namo Bintang Village, Pancur Batu District, Deli Serdang Regency. In the management of TPA that still uses an open dumping system and the limited gas control facilities, the result is that there is less than optimal waste management. This has implications for the potential for the formation of methane gas (CH4) which contributes significantly to increasing GHG concentrations in the atmosphere.

The Impact of Methane Gas Emissions on the Environment

Methane gas emissions from the TPA have a significant impact on the environment, contributing to climate change and air pollution. The methane gas produced from the anaerobic decomposition process is a potent greenhouse gas, with a global warming potential 28 times higher than carbon dioxide over a 100-year time frame. The emissions from the TPA not only contribute to climate change but also have negative impacts on human health and the environment.

Efforts to Reduce Methane Gas Emissions

Efforts to reduce methane gas emissions can be done by implementing a more integrated waste management system, one of which is through the 3R (Reduce, Recycle, Reuse) approach. This approach aims to reduce the amount of waste that enters the landfill, optimizing recycling, and re -utilizing existing materials, so as to minimize the formation of CH4 gas. In the long run, the application of this method will not only reduce GHG emissions, but also has a positive impact on overall waste management and maintain environmental sustainability.

The Importance of Sustainable Waste Management

Through this analysis, it is important for related parties to understand the potential of methane gas emissions from the TPA and find a more sustainable solution in waste management. With more systematic efforts, it is expected to create a cleaner and healthier environment for the community, and contribute to the prevention of climate change. Sustainable waste management is essential for reducing GHG emissions, conserving natural resources, and protecting the environment.

Conclusion

In conclusion, the analysis of potential methane gas emissions from the TPA waste is crucial for understanding the impact of waste management on the environment. The case study of TPA Namo Bintang, Medan, North Sumatra, highlights the importance of implementing a more integrated waste management system, such as the 3R approach, to reduce methane gas emissions and promote environmental sustainability. By working together, we can create a cleaner and healthier environment for the community and contribute to the prevention of climate change.

Recommendations

Based on the analysis, the following recommendations are made:

Evaluating the effectiveness of the 3R approach: The effectiveness of the 3R approach should be evaluated to understand its impact on GHG emissions and the environment.

Limitations of the Study

The study has several limitations, including:

Limited data availability: The study was limited by the availability of data on GHG emissions and waste management practices in the TPA.
Small sample size: The study was limited by the small sample size of the TPA.
Limited scope: The study was limited in scope to the TPA and did not consider other factors that may impact GHG emissions and the environment.
