This paper presents an umbrella review of 47 previous reviews published from 2008 to 2021, covering papers from 1949 to 2021. As a result, bases were set to clarify the full life cycle of recycled plastic fiber-reinforced concrete (RP-FRC), including circularity strategies, to strengthen consistent contributions to the area in the future. The review compares and discusses the types of plastic waste suitable for producing plastic fibers, the effects of recycled plastic fibers on concrete properties and the sustainability of this recycling alternative.

However, there is still a huge unexplored potential for P-recovery specially in the regional framework from the four main P-rich waste resources: food waste, manure, mining waste, and sewage sludge. This study reviews recovery methods of P from these secondary resources comprehensively. Additionally, it analyzes the Nordic viewpoint of P-cycle by evaluating Nordic reserves, demands, and secondary resources to gain a systematic assessment of how Nordic countries could move toward circular economy of P. Results of this study show that secondary resources of P in Nordic countries have the potential of replacing mineral fertilizer in these countries to a considerable extent.

The common strengths presented are the quality of cores (used parts) received and the strategic location of the case companies to optimize the reverse logistic network. The highlighted weaknesses are lack of established standard operating procedures, low employee specialization skills, and poor adoption of Industry 4.0 enabling technologies. The identified opportunity includes specific market demand from targeted customers, while the most prevalent threats are supply uncertainty in quantities of cores, no ELV policy in Malaysia, an inadequate subsidy system, customer misconceptions, and a market acceptance barrier for ELV products.

Encouraging sustainable clothing disposal methods that extend the useful life of products is an effective way to deal with textile waste. One of the most sustainable clothing disposal methods is social recycling, which entails giving away unused products by allowing other consumers to obtain them for free. Thus, this study aims to investigate the motivations affecting the consumers’ social recycling behaviors in Turkey. In this context, online and offline surveys were conducted on 478 participants and analyzed utilizing structural equation modeling. The findings show that altruism, the warm glow of giving, and social benefits influenced social recycling behavior, while environmentalism had no effect. These results support the social exchange theory which proposes that both other-oriented and self-serving motivations affect behavior. One of the most crucial findings of the study is that the warm glow of giving has a mediating effect between altruism and social recycling behavior. This research is also important in terms of revealing that women engage in more social recycling behavior than men. The findings have important implications for practitioners and researchers interested in sustainable clothing disposal.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"25 5","pages":"3021 - 3032"},"PeriodicalIF":3.1,"publicationDate":"2023-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4211996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}
