Research on Innovative Models of Waste Recycling in Urban Infrastructure

Abstract

As urbanization accelerates, waste management has increasingly become a critical factor constraining sustainable urban development. Facing the growing urban population and continuous waste generation, traditional waste treatment methods such as landfill and incineration are unable to meet the modern city's demands for environmental protection and resource recycling. These methods often focus on the end stages of waste management—clearance and disposal—neglecting the importance of waste reduction at the source and resource recovery. To address this challenge, urban infrastructure must shift its approach and explore innovative models of waste recycling. These innovative models emphasize reducing waste generation at the source, improving resource recovery rates, and achieving waste minimization, resource recovery, and harmlessness. By shifting from the traditional linear economic model and viewing waste as a renewable resource, these models leverage scientific and effective means for recycling, thus achieving a win-win for economic and environmental benefits and contributing to the sustainable development of cities.
