Results show that CHPP significantly reduces CEI and SEI. Four mediating variables, including total and average levels of government environmental attention and clean energy consumption, play key roles in the effectiveness of the policy. The effect is more notable in cities with higher temperatures, lower resource dependence, lower energy consumption, classification in the second pilot wave, key governance regions, and dispersed spatial layouts.

However, the lack of validated large-scale inventory data and limited use of uncertainty/statistical analysis cast doubts on the findings. This study aims to investigate the validity of these conclusions by modelling LCA for pyrolysis (PYR) and gasification (GASI) using two data sources: Aspen-generated data (ASP) and aggregated literature data (LIT). The novelty of this study lies in applying uncertainty propagation tailored to each source, enabling systematic evaluation of result variability. Using a functional unit of 1 kg mixed polyolefin (MPO) waste treated, our results show that Aspen-based scenarios exhibit narrower uncertainty ranges than their literature-based counterparts. For instance, the variability in terms of global warming potential for PYRO (ASP) ranged from 0.751 to 1.53 kg CO₂ eq/kg MPO waste treated, whereas that of PYRO (LIT) ranged from 1.24 to 6.51 kg CO₂ eq/kg MPO waste treated. Similarly, GASI (ASP) had a more constrained 95 % confidence interval (from 2.56 to 4.97 kg CO₂ eq/kg MPO waste treated) compared to that of GASI (LIT), which spanned from 2.20 to 15.58 kg CO₂ eq/kg MPO waste treated. Other impact categories, including acidification, freshwater eutrophication, freshwater ecotoxicity, and resource depletion, also showed considerably varied results. These disparities largely stem from many underlying assumptions and simplification during Aspen modelling, leading to reduced number of variables. Conversely, literature-based LCA models are constrained by repeated reuse of data and by inconsistencies in system boundaries, which exacerbate result variability. These issues suggest that the consensus in support of chemical recycling rests on a narrower data foundation than often assumed. As such, we recommend that LCA findings be used as policy reference only when supported by robust case-specific data, and transparent uncertainty analysis. While these findings provide crucial perspective for stakeholders and decision-makers, it is important to note that the methodology applied in this study is limited by various practical factors, including simplification of Aspen modelling and LCA system boundaries, as well as inherent limitations related to data gathering protocol.</div></div>","PeriodicalId":21153,"journal":{"name":"Resources Conservation and Recycling","volume":"227 ","pages":"Article 108764"},"PeriodicalIF":10.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145823270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
