However, the role of digitalization in waste management (WM) is underexplored, and the literature remains fragmented. This study explores the synergy between CE principles in tourism and decarbonization in the waste sector through digitalization, using case studies from Taipei (Republic of China) and Sukunan (Indonesia). By examining the integration of digital tools in WM systems, the study highlights how these cities leverage technology to promote net-zero emissions and sustainable practices, particularly in the context of tourism. The research employs a mixed-methods approach, combining qualitative data from focus group discussions, semi-structured interviews and secondary data analysis. The findings reveal that digitalization has significantly improved WM efficiency, resource recovery (RR) and carbon footprint reduction in both study areas. Notably, the study demonstrates that tourism plays a role in driving these digitalization efforts, particularly through the adoption of CE practices in WM. The results suggest that digital solutions, when tailored to local contexts, can accelerate decarbonization and enhance sustainability. In Sukunan, technological adoption generated 780 new jobs and raised average household incomes by USD 45 monthly. These initiatives reduced landfill waste by 30% and cut CO₂-equivalent emissions by about 0.3 million metric tonnes annually. Taiwan's 'Pay-As-You-Throw' (PAYT) system is a benchmark, showcasing effective WM and resource recovery practices. Digitalization is projected to trim WM costs by 35%, reduce annual expenses by 3.6%, generate USD 493 billion in revenue over decades and subdue global CO₂ emissions by 15% by 2030. Overall, this work emphasizes the potential for replicating such strategies in other cities, with consideration for local conditions, to achieve sustainability and decarbonization goals in the tourism and WM sectors.</p>","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"734242X251326268"},"PeriodicalIF":3.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143754771","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}

The oil transport through oil tankers and pipelines has further aggravated the risk of the oil spill. This has led to the necessity to develop an effective, environment-friendly, versatile oil spill clean-up strategy. The current review article analyses various nanotechnology-based methods for marine oil spill clean-up, focusing on their recovery rate, reusability and cost. The authors weighed the three primary factors recovery, reusability and cost distinctively for the analysis based on their significance in various contexts. The findings and analysis suggest that magnetic nanomaterials and nano-sorbent have been the most effective nanotechnology-based marine oil spill remediation techniques, with the magnetic paper based on ultralong hydroxyapatite nanowires standing out with a recovery rate of over 99%. The chitosan-silica hybrid nano-sorbent and multi-wall carbon nanotubes are also promising options with high recovery rates of up to 95-98% and the ability to be reused multiple times. Although the photocatalytic biodegradation approach and the nano-dispersion method do not offer benefits for recovery or reusability, they can nevertheless help lessen the negative ecological effects of marine oil spills. Therefore, careful evaluation and selection of the most appropriate method for each marine oil spill situation is crucial. The current review article provides valuable insights into the current state of nanotechnology-based marine oil spill clean-up methods and their potential applications.</p>","PeriodicalId":23671,"journal":{"name":"Waste Management & Research","volume":" ","pages":"507-521"},"PeriodicalIF":3.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141447107","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}

The results showed disaggregate and unbalanced research distribution on the impacts of FLW among the countries, with China and the United States having the highest contributions. The identified major research themes relating to sustainable agri-food systems are food waste and sustainable systems, food waste management and food waste impact assessment. Moreover, the circular economy was found to be a relatively new approach being explored in agri-food systems to promote FLW reduction and ensure sustainability of resource use.

It is reported that textile materials are discarded daily, representing approximately 1.5% of the generated waste around the world. Over the past few decades, special attention has been given to the used clothes in all regions globally, which can reduce energy costs by 80% and also represent a source of raw materials economically profitable and environmentally responsible. This review article attempted to address different topics including: source of solid textile waste, environmental impact of textile waste as a result of massive consumption of clothing, textile waste management processes such as recycling, reuse of textile waste, landfill and incineration and energy recovery from textile waste. Narrative review with collection of recent quantitative information was carried to reflect the status of textile solid waste. In this article, the possibilities of bio-ethanol production from textile waste as valuable cellulosic raw material are investigated and presented. Results show that developing countries lack of systematic waste management. On another side of the globe, some countries are trying to recover energy these days by incineration. The heat and power that recovered from this process can be used instead of other energy sources. Throughout the incineration process, flue gases (CO₂, H₂O, O₂, N₂) are generated so it should be properly designed to avoid pollution.

This study aims to assess the suitability of a grape stem-based ingredient for rabbit feeding. The stem was dried using flash drying technology to prevent rapid spoilage and stabilise the ingredient. Then, its nutritional value was evaluated resulting in a high fibre (>40%) and polyphenol (>6%) content ingredient with antioxidant and antimicrobial activity against <i>Staphylococcus aureus</i>. A feed efficiency trial was conducted and inclusion rates of up to 10% of grape stem-based ingredient did not affect animals' mortality, average daily feed intake, daily gain or feed conversion ratio. In conclusion, grape stem-based ingredient arises as a secondary feedstuff for cuniculture reducing the dependence on other fibre sources, such as cereals or sunflower hulls.
