ポルトガル・セトゥーバルにおける家庭有機廃棄物の3つの分別収集戦略（ドアツードア、持参方式（グリーンバッグなし）、持参方式（グリーンバッグあり））をLCAとLCCで評価。持参方式（グリーンバッグなし）が最も低い環境・経済影響を示し、グリーンバッグを含む方式が最大の影響を示した。EU指令遵守のための実践的示唆を提供。
English
This study assesses three selective collection strategies for household organic waste (door-to-door, bring-point without green bags, bring-point with green bags) in Setúbal, Portugal using LCA and LCC. The bring-point strategy without green bags had the lowest environmental and economic impacts, while the one with green bags had the highest. Provides practical insights for municipalities to comply with EU waste directives.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の自治体にとって、家庭有機廃棄物の収集方式の環境・経済比較は参考になる。EUの循環経済指令に基づくが、日本でも食品廃棄物削減やバイオマス利用が進む中、実践的な知見を提供する。
In the global GX context
This study provides a comparative LCA/LCC of organic waste collection strategies, offering evidence for municipalities transitioning to circular waste management. While focused on Portugal, the methodology and findings are applicable to other urban contexts.

📄 Abstract（原文）
As of January 2024, under Directive 2018/851, European Union Member States are required to implement selective collection and treatment of household organic waste, targeting landfill reduction and transition towards a circular economy. Different strategies within the reverse supply chain present distinct environmental and economic implications. This study assesses three selective collection strategies in Setúbal, Portugal: (1) door‐to‐door, with containers placed at property entrances for scheduled collection; (2) bring‐point system (excluding green bags); and (3) bring‐point system (including green bags). In both bring‐point strategies, users deposit waste in public containers periodically emptied by municipal lorries. Life Cycle Assessment (LCA) was applied to quantify environmental impacts, following ISO 14040 and the Product Environmental Footprint methodology. Primary data from Setúbal's operations were modelled in SimaPro 9.5.0.2, complemented with secondary data from Ecoinvent. Economic impacts were assessed using Life Cycle Costing (LCC), considering container manufacture and transport, washing of household containers, selective collection and transport to treatment and production and distribution of green bags. Results indicate that the bring‐point strategy excluding green bags had the lowest environmental and economic impacts. The bring‐point strategy including green bags exhibited the highest impacts, while door‐to‐door showed intermediate performance. Recommendations include expanding the bring‐point strategy excluding green bags, standardising 10 L containers to reduce washing‐related impacts, optimising collection routes and progressively adopting low‐emission vehicles. Despite geographical and data‐related limitations, the results provide practical insights for municipalities aiming to comply with EU legislation and support the transition towards efficient circular management of household organic waste.
