Comparing The Gaps Between Policy Making and Implementation in Solid Waste Management: Cases of Germany, Japan, India, Usa, Kenya and Singapore

Solid waste management is essentially one of the most pressing problems in today's world; It increases its importance every day as both an environmental and social issue. Rapid population growth, urban accumulation, and unbridled consumption habits not only increase the amount of waste but also create a multi-layered crisis ranging from pollution to public health and from there to economic losses. This is exactly why governments are under serious pressure to produce ambitious and solution-oriented policies. But the point is, the gap between those theoretical goals on paper and the hard realities on the ground never closes. While this state of disconnection reduces the efficiency of policies, it also, unfortunately, disrupts dreams of sustainable development. The main axis of this article is the wide gaps between policy design and implementation practices. Why are there these gaps? What are the consequences? While pursuing these questions, we examine the practices of countries with very different administrative and economic structures, from Germany to Japan, from India to Kenya and Singapore, through comparative case studies. At the centre of our discussion is the heavy burden of these disruptions on social justice and economic efficiency. The point we have reached is clear: Failure in waste management is not just a technical deficiency; on the contrary, it is a phenomenon that is linked to the quality of governance, political determination, and institutional flexibility. Therefore, to improve the processes, not only a technical solution but also a more holistic perspective is required. Methodologically, this study employs a multi-layered qualitative comparative case analysis (QCA), utilizing thematic analysis and data triangulation to systematically decipher the structural policy-implementation gaps across six diverse national contexts.
