Current high density energy storage options on the market rely heavily on lithium (Li)-based technologies. A projected increase in energy storage technology demand has sounded the alarm on a need to develop suitable approaches for the recovery of the various constituent metals from spent Li-ion batteries (LIBs). This, coupled with urgent consideration for the environment has necessitated the investigation of various LIB metal recovery techniques. In this work, we explore the novel application of the hydrohalic acids, hydrobromic (HBr) and hydroiodic (HI) acid, as lixiviants in a series of leaching experimental investigations on LIB cathode powder. A methodology for battery disassembly and cell cathode material recovery is presented leading up to the metal leaching. Our results indicate that the lixiviants can be utilized in the absence of a reducing agent which is typically present in conventional LIB leaching systems. The highest recoveries of the constituent metals, Co, Li, Mn and Ni in the HI system were 92.9 %, 93.6 %, 93.1 % and 94.5 % respectively, at an operating temperature of 60 ℃ and with a 1.5 M HI concentration. The HBr system achieved metal recoveries of 90.6 %, 89.1 %, 83.1 % and 96.4 % for Co, Li, Mn and Ni respectively, at 60 ℃ and using 2 M HBr. Kinetic studies showed that the leaching mechanism for both acids follow a chemical reaction-controlled model.</p></div>","PeriodicalId":101276,"journal":{"name":"Waste Management Bulletin","volume":"2 3","pages":"Pages 275-288"},"PeriodicalIF":0.0,"publicationDate":"2024-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949750724000750/pdfft?md5=fdac8fccc087d3e8cf59f314021300e8&pid=1-s2.0-S2949750724000750-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142122325","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}

PVC flex banners used for advertising or marketing purposes have a short-term use [average up to 45 days]. PVC flex banners are usually annihilated, piled in landfills, incinerated, or buried under the soil, thus causing severe damage to the environment. This systematic literature review highlights the research carried out on this topic over the last two decades and discusses industry practices in producing PVC flex banners, the environmental impact of PVC flex banners due to annihilation, and reuse and recycling methods for PVC flex banners. One of these opportunities is upcycling, which is an important part of the reuse strategy. These flex banners can be reused in the fashion industry as upcycled products [high-value functional and aesthetic products] and accessories through zero-waste fashion production processes [especially used in pattern designing and cutting stages]. These include primarily bags and luggage, apparel, footwear, worker uniforms, and accessory upcycle products. Based on findings from the systematic review, it recommends a conceptual framework that emphasises the impact of end-of-life PVC flex banners and offers ways for reuse that avoid piling in landfills, incineration, and burying these wastes under the soil, reducing the impact on the environment. The studies suggesting the production of upcycling products from end-of-life PVC flex banners by the zero-waste fashion production process have not been sufficiently researched and reported, and they are a novel method of reusing resources.</p></div>","PeriodicalId":101276,"journal":{"name":"Waste Management Bulletin","volume":"2 3","pages":"Pages 249-265"},"PeriodicalIF":0.0,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949750724000762/pdfft?md5=d0daf3e1f9086d3c0f9f2e868906b02a&pid=1-s2.0-S2949750724000762-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142088412","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}

This study explores the potential of fruit and vegetable waste and by-products valorization using green and novel technology such as supercritical, microwave, ultrasound, high hydrostatic pressure and cold plasma technology for developing sustainable food packaging solutions. By utilizing components such as pectin from citrus peels, starch from potato skins, and fibers from banana peels, innovative biodegradable and compostable packaging materials can be produced. These materials not only reduce reliance on petroleum-based plastics but also enhance the circular economy by repurposing waste that would otherwise contribute to environmental pollution. The research highlights various processing methods, including extraction, blending with biopolymers, and composite formation, to convert by-products into films, coatings, and moulded packaging. The resulting products exhibit desirable properties such as biodegradability, flexibility, mechanical strength, and, in some cases, antimicrobial and antioxidant activities, which can extend the shelf life of food products. Moreover, nanotechnology application in fruits and vegetables-based packaging is also discussed. Despite the promising benefits, challenges such as cost, scalability, and consumer acceptance remain. Addressing these issues through continued research, supportive policies, and industry collaboration is crucial for the widespread adoption of these sustainable packaging solutions.

The performance of UASB was able to remove 154.75 g/L of chemical oxygen demand (COD) content of the leachate originally anticipated to emit 2.99 L of CH₄ production into the atmosphere.

The rate-limiting step of CH₄ desorption was controlled by IMT at the beginning and then by EMT after 30 days of the experiment. The strongly decreased EMT factor was counterbalanced by an increased value of the IMT factor at before 5 days of the experiment. It would be of interest to predict the methanogenesis kinetics of CH₄ desorption using the Generalized Fulazzaky equations, which cannot be evaluated using other models.
