Hierarchically porous zeolites can mitigate this problem. In this review, the catalytic pyrolysis of non-edible lipids for aromatic hydrocarbons and the mechanism of aromatization are comprehensively summarized. First, the synthesis of hierarchically porous zeolite catalysts, including hard template methods, soft template methods, and postprocessing methods, which are necessary for further discussion of catalyst applications and aromatization mechanisms, is discussed. Hierarchically porous zeolite catalysts, which retain the excellent catalytic activity and selectivity of microporous zeolites, can essentially and substantially improve mass transfer and diffusion efficiency in zeolites to avoid fast deactivation of catalysts due to coking. Second, the application of hierarchically porous zeolites in aromatic hydrocarbon production is summarized. The loading of metal oxides in hierarchically porous zeolites can largely improve the deoxygenation performance of oxygen-containing lipid feedstocks. This review also discusses the aromatization mechanism used during catalytic pyrolysis to produce renewable liquid products. The formation of olefins or unsaturated groups and dehydrogenation are the critical steps for aromatization. Future research can prioritize the synergistic interaction between micropores and mesopores in hierarchically porous zeolite catalysts. Efforts can also be directed towards rational modification of the acidity of catalysts through methods such as surface modification and support optimization. This review provides necessary information about technologies for the sustainable transformation from fossil fuel-based aromatic hydrocarbons to bio-based aromatic hydrocarbons.</div></div>","PeriodicalId":100245,"journal":{"name":"Circular Economy","volume":"4 1","pages":"Article 100128"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143562254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the launch of the “Zero Waste City” initiative in Hengshui, China, the city has continuously promoted waste reduction at the source and resource utilization. Business models and institutional mechanisms for the utilization of various types of solid waste have been actively explored, and a model for reducing pollution and carbon emissions through the production of “gas, electricity, heat, and fertilizer” in the agricultural sector has been established. In this study, an analysis of pollution and carbon emission reduction in the Hengshui “Zero Waste City” construction is conducted on the basis of the “driving force–pressure–state–impact–response” (DPSIR) model, and the entropy weight-TOPSIS method is used to standardize the data from 2020 to 2023. In addition, this study uses the approved clean development mechanism (CDM) method (AMS.Ⅲ.D.ver.21) to analyze the greenhouse gas emission reduction effect of the comprehensive biogas project in Anping County, Hengshui City. The results revealed that the reduction in pollution and carbon emissions of the Hengshui “Zero Waste City” construction from 2020 to 2023 was significant. The core factor affecting the “Zero Waste City” construction in Hengshui is the development of social and economic activities; the increase in fixed asset investment in agriculture, forestry, animal husbandry, and fisheries; the improvement in residents’ income; and the increase in the employment rate. Hengshui has driven the construction of a “Zero Waste City” through industrial development, forming a comprehensive utilization model of livestock manure that combines the production of gas, electricity, heat, and fertilizer. This is in line with the demand for the construction of a “Zero Waste City” in Hengshui. Moreover, the case project can reduce greenhouse gas emissions by 87,208.5 tons of CO₂ equivalent per year, with a reduction rate of over 64%.</div></div>","PeriodicalId":100245,"journal":{"name":"Circular Economy","volume":"4 1","pages":"Article 100130"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143643959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reduce the environmental impacts related to plastic production and consumption, European policies call for increased plastic recycling. Polystyrene is a main commodity plastic with good recyclability; however, today, recycling levels for polystyrene are lower than those for other commodity plastics. To promote plastic circularity and increase polystyrene recycling, this study investigates feedstock availability for polystyrene recycling, using Finland as a case study. Key waste streams containing polystyrene are explored: municipal solid waste, plastic packaging waste, construction and demolition waste, as well as waste from electrical and electronic equipment. A spreadsheet-based material flow model was developed to estimate the extraction of polystyrene from waste streams in different scenario simulations. Data entered into the model was collected via literature review supported by expert interviews. This model can be applied to other regions by tailoring the input data. The results show significant potential for polystyrene recycling by implementing collection schemes for polystyrene at construction sites and by extracting polystyrene from separately collected plastic packaging waste and waste electronics, as well as by introducing industrial post-sorting of residual municipal solid waste. The findings indicate the potential of more than 10 thousand tonnes of polystyrene as feedstock for recycling, of which up to 5.2 thousand tonnes originate from the construction sector, 2.6 thousand tonnes from separately collected plastic packaging waste, 1.8 thousand tonnes from waste from electrical and electronic equipment, and 3.2 thousand tonnes from residual municipal solid waste. It can be concluded that there is significant potential for polystyrene recycling in Finland, which is partly driven by European recycling targets.

In the 2021–2022 season alone, Bangladesh produced 52.25 million tons of rice straw, with an energy potential of 189.52 × 10⁹ MJ. This study provided tangible information on various aspects of rice straw, including its availability, distribution, energy potential, common uses, and causes and impact as waste. Moreover, it is a comparative analysis of traditional uses alongside recent innovation utilization of straw. Suggested management options incorporating multifaceted conversion strategies are explored to encourage alternative utilization, which requires policies and diverse initiatives with financial support. Innovative approaches, such as the conversion of straw to renewable energy, along with alternative application strategies, are highlighted as promising technologies that can enhance flexibility and efficiency in utilization. Moreover, a comparative analysis has been carried out on traditional straw uses alongside recent innovations in its utilization, such as biogas production, biofuel generation, biochar creation, and composting, alongside value-added applications such as papermaking and industrial materials. A strategic approach to overcoming challenges and leveraging opportunities in rice straw utilization through technological advancements is proposed, aiming for sustainable and environmentally friendly practices.
