Summary: With a population of over 9 million, waste management system (WMS) challenges in Tehran can serve as lessons for other middle-income cities. Despite efforts and investments, the recycling rate has remained constant at around 18% over the past decade. Short-sighted decisions, lack of understanding of different aspects of the system, and lack of involvement from stakeholders are the main weaknesses in the governance of Tehran's WMS. Inclusivity and financial sustainability prove to be the most challenging aspects. Inadequate waste management framework is a national challenge. Although some improvements have been made in disposal methods and composting plant capacity, the quality of the 3Rs (reduce, reuse, and recycle) remains poor, with controlled landfill being the main disposal method for approximately 50% of generated waste.

Summary: The development of controlled-release fertilizer formulation is important for preventing environmental pollution caused by nutrient leaching and volatilization. This study combined biochar-based fertilizer with encapsulation technology to improve the nutrient release mechanism. Optimal conditions for synthesizing urea-impregnated biochar (UIB) were determined using central composite design, and the release of nitrogen was described by mathematical models. Results showed that encapsulated UIB (EUIB) achieved complete release of nitrogen in water and exhibited improved water retention in sandy-textural soil. Therefore, EUIB derived from peppercorn waste has the potential to be used as a sustainable controlled-release fertilizer for agriculture.
