The impact of solid waste on climate change is considerable, as emissions from landfills and dumps are a major source of emissions of methane. Strong greenhouse gas methane is one of the main causes of climate change, is generated through the breakdown of organic waste in anaerobic environments. Proper waste management is essential in order to mitigate these emissions and minimize the environmental impact. Waste prevention, composting, and recycling all play crucial roles in reducing greenhouse gas emissions associated with solid waste. By implementing strategies such as composting organic waste and capturing methane from landfills, significant reductions in emissions can be achieved. Municipal solid waste management has the ability to significantly aid in the mitigation of climate change by reducing global solid waste emissions towards a future of net-zero warming. By addressing the issue of solid waste management, we can actively combat climate change and safeguard the environment for future.
