Household Waste Management And Urban Supply Chains Practices In Batna, Algeria: Toward An Integrated Circular Economy Model
Authors : Bennecer Afaf . Bouguelaa Mohammed .
Abstract
This study examines how household waste behaviors in Batna (Algeria) disrupt the municipal supply chain for recyclables and organics, and how circular economy policies might mitigate these disruptions. We integrate mixed methods – a stratified household survey (n=735), waste composition audits across income-level districts, stakeholder interviews, material flow analysis, and system dynamics simulation – to link micro-level behaviors to macro-system outcomes. Batna households generate waste rich in organics (avg.~61%) and have low segregation rates: only ~9% consistently separate recyclables, ~37% sometimes, and ~54% not at all. Despite ~71% of homes having bins, only ~40% of households demonstrate moderate recycling awareness. Contaminated waste streams greatly reduce recovery rates and raise unit costs of transport and processing. Baseline simulation shows ~27% recycling recovery, with transport and processing costs of 7000–96000 DZD/ton. Under moderate and high participation scenarios, recovery rises to 45% and 61%, while per-ton costs fall by ~20–30%. These results confirm that poor household sorting cascades into supply chain bottlenecks and costs, undermining local circularity. We propose an integrated model linking households to supply chains via policy levers
