摘要

The Management of Construction and demolition (C&D) waste sector in Delhi is one of the extensive approaches in India that implements circular economy principles in urban waste management. The Comprehensive analysis of government data in the year 2020–2023 is done from which this study evaluates the effectiveness and efficiency of C&D waste management systems in Delhi. The outcomes of circular economy, utilization of infrastructure capacity, spatial distribution patterns are analyzed across administration zones in Delhi using the secondary data obtained from municipal corporation performance data, central pollution control board records and Delhi pollution control committee annual reports. The study says that North DMC generates 35.9%, South DMC generates 32,7% and East DMC generates 29.2% of total C&D waste (1,237.96 TPD) resulting in significant spatial inequities in waste generation. The theoretical processing capacity is of 5,150 TPD across 5 facilities but due to substantial infrastructure underutilization, the actual operational capacity is of 3,150 TPD. The market demand exceeds the processing capacity rather than utilization of product being the primary constraint stating that the exceptional offtake efficiency is of 93.72% while the processing efficiency is of 80.39%. The study finds the differences between operational implementation and policy frameworks wherein the economic cycles influence the generation patterns significantly (± 27% variation in NDMC data). The contribution to the sustainable development goals 11 and 12 is attained by the Delhi’s model demonstrating the successful partial circular economy through strong public-private partnerships and high material recovery rates (97%). However, the impact of sustainability is limited widely by the regional fragmentation across NCR. The policy-practice integration strengthening, enhancement of inter-regional coordination and optimization of infrastructure utilization to achieve sustainable urban development objectives is done from the findings which provides evidence-based recommendations.
