日本語
飲料用PET包装システムを対象に、エネルギー源・再生材料比率・廃棄物管理の変更がライフサイクル環境影響に与える効果をLCAで評価した。将来シナリオでは総合環境スコアが70.8%減、気候変動54.3%減、化石資源使用63.8%減となった。一方、再エネ移行に伴い鉱物・金属使用がわずかに増加するトレードオフも示された。
English
An LCA of a beverage PET packaging system assessed how shifting energy sources, raising recycled content, and changing waste management affect life-cycle impacts. The future scenario cut the total environmental score by 70.8%, climate change by 54.3%, and fossil resource use by 63.8%. A slight rise in mineral and metal use signals a trade-off of decarbonizing energy.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では容器包装リサイクル法やプラスチック資源循環戦略、飲料・食品企業のScope 3排出削減とリサイクル材調達の両立が課題。本LCAは再エネ・再生材・廃棄物管理の組合せ効果を定量化し、SSBJ開示における製品ライフサイクル排出の裏付けデータとして活用余地がある。
In the global GX context
Aligns with global packaging circularity and EPR trends under CSRD/PPWR and Scope 3 disclosure. It offers a quantified, scenario-based method for linking renewable energy, recycled content, and waste management to life-cycle climate outcomes, useful for transition-plan and product-footprint reporting.

📄 Abstract（原文）
Renewable energy sources and circular economy principles play a significant role in reducing the environmental impact of the food industry. Implementing low-emission energy sources, using recycled materials, and properly managing packaging at the end of its life can contribute to reducing the environmental impact of products throughout their life cycle. The aim of this study was to assess the impact of changes in energy sources, the share of recycled materials in packaging materials, and packaging waste management methods on the potential environmental impact of a beverage packaging system throughout its life cycle. The study conducted a life cycle analysis of three packaging system scenarios consisting of a 1.5 L PET bottle with a cap and label, a secondary packaging unit, and a shipping container. The functional unit involved the packaging, transportation, and storage of 12,000 L of beverage. Under the conditions assumed in the study, the future scenario resulted in a 70.8% reduction in the total environmental score compared to the baseline scenario, including a 54.3% reduction in climate change and a 63.8% reduction in fossil resource use. This improvement was due to the combined effect of a higher share of renewable energy, a higher share of recycled materials, and changes in waste management. At the same time, the transition towards renewable energy was accompanied by a slight increase in the use of minerals and metals compared to the actual scenario, indicating a possible environmental trade-off associated with decarbonizing the energy system.
