日本語
台湾の医療機関2施設と連携し、使用済み点滴バッグを回収・洗浄・再ペレット化して針廃棄容器へと再生する循環システムを構築した。容器はISO 14021とISO 23907-1に適合し、病院に戻されて素材循環を成立させた。クレードル・トゥ・ゲートの炭素原単位は1容器あたり1.852 kg CO2-eqと算出された。経済性は定性評価に留まり、環境優位性の定量証明には至っていない。
English
A circular system was built in Taiwan with two hospitals to collect, clean, and reprocess used IV infusion bags into recycled pellets, then into sharps containers returned to the hospitals. Containers met ISO 14021 and ISO 23907-1, and cradle-to-gate footprint was 1.852 kg CO2-eq per container (1.587 raw material, 0.265 manufacturing). Economics were assessed only qualitatively, so environmental superiority and viability remain unproven.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
医療系プラスチックの再資源化と製品炭素原単位の算定は、Scope 3や循環経済開示を進める日本企業・医療機関にとって参考になる実装例。ただしSSBJ・有報との直接接続はなく、定量比較の不足が課題。
In the global GX context
Offers a traceable, ISO-verified case of healthcare-plastic circularity with a product-level carbon baseline, relevant to Scope 3 and circular-economy disclosure under CSRD/ISSB, though it lacks a virgin-plastic benchmark and quantified economics.

📄 Abstract（原文）
In 2024, Taiwan generated approximately 130,000 metric tons (MT) of medical waste, including about 42,000 MT of hazardous waste. Despite the implementation of circular economy initiatives, most of the medical waste is still incinerated and landfilled, thereby increasing the environmental burden through dioxin emissions and secondary pollution. Current recycling practices are aimed at converting medical plastics into secondary products but face logistical and operational challenges. This study developed a circular recycling system for medical intravenous (IV) infusion bags in Taiwan. In collaboration with two medical institutions, used IV bags were collected, sorted, cleaned, and reprocessed into recycled plastic pellets via a patented recycling-and-pelletization process. The pellets were incorporated into sharps containers, which were returned to participating hospitals, thus establishing a circular material pathway within the healthcare sector. The entire process was independently verified for traceability and regulatory compliance. The containers were assessed for recycled content, safety performance, and cradle-to-gate carbon footprint. The containers complied with ISO 14021 and ISO 23907-1 and were adopted by two hospitals in northern Taiwan. The carbon footprint was estimated as 1.852 kg CO 2 -eq per container, comprising 1.587 kg CO 2 -eq from raw-material acquisition and 0.265 kg CO 2 -eq from manufacturing. The economic dimension was discussed qualitatively through major cost components and potential avoided-cost mechanisms. The interpretation was limited by the unavailability of process data, financial and subsidy information, a quantitative base-case model, and a functionally equivalent virgin-plastic benchmark. The findings demonstrate practical implementation and provide a case-specific carbon-footprint baseline without establishing quantified environmental superiority or economic viability.
