Our analysis reveals that material extraction and processing contribute 30 % of the total value added while generating 56 % of upstream employment. Furthermore, LNMO cells exhibit 20–25 % lower greenhouse gas emissions compared to NMC-811 cells. Shifting anode sourcing to Norway further reduces these emissions to levels comparable to LFP cells, while decreasing job creation in the mining industry.

This study conducts a systematic literature review of PET-related research published between 2000 and 2024, utilizing the Web of Science (WoS) Core Collection database's Advanced Search function to retrieve relevant literature. The searching strategy employed predefined inclusion and exclusion criteria to ensure the selection of studies specifically related to PET recycling and reuse, ultimately identifying 4847 key research sources after manual screening. To systematically analyze the selected literature, a bibliometric clustering approach using VOSviewer was applied, revealing four dominant research areas: environmental impacts and economic performance, recycling technologies, waste management, and sector-specific applications. A conceptual framework was developed to synthesize key research trends, methodological approaches, and limitations across these domains.&lt;/div&gt;&lt;div&gt;This study revealed that while PET recycling technologies have advanced significantly, challenges persist in terms of energy efficiency, cost competitiveness, and scalability. Life Cycle Assessment (LCA) studies often overlook the end-of-life phase, limiting the accuracy of environmental impact evaluations, particularly in construction applications. Additionally, economic analyses of PET circularity remain fragmented, often failing to capture regional cost variations, market fluctuations, and the economic feasibility of emerging recycling methods. The study also identifies a lack of spatial-temporal research on PET material flows, limiting the ability to design adaptive and region-specific waste management strategies.&lt;/div&gt;&lt;div&gt;Consequently, several promising research opportunities have been identified: (1) improving end-of-life lifecycle assessments for PET applications, particularly in construction; (2) optimizing chemical recycling methods; (3) enhancing enzyme catalytic efficiency, thermal stability, and scalability; (4) leveraging artificial intelligence (AI) for precise PET sorting and waste flow optimization; (5) developing PET-specific data frameworks that incorporate spatial-temporal dimensions for tracking production, consumption, and recycling trends; (6) integrating informal and formal PET recycling systems in emerging economies; (7) exploring consumer perceptions, trust, and willingness to pay for recycled PET products; and (8) examining the interaction between recycling habits and infrastructure to optimize recycling system adoption and efficiency.&lt;/div&gt;&lt;div&gt;Previous reviews predominately focused on technological advancements, environmental impacts, or specific industries.

Although refrigeration significantly enhances food preservation conditions, our findings indicate that it may paradoxically increase household food waste. Specifically, refrigerator usage is associated with a 24.35 % rise in food waste and a 29.29 % increase in calorie loss among refrigerating households. This effect diminishes over time and is moderated by higher household income, greater dietary knowledge, and increased education levels of food decision-maker. The quantity of stored food at home serves as a mediating factor: refrigerators encourage greater storage, thereby increasing food waste.
