Two flux compositions MnO<sub>2</sub>-SiO<sub>2</sub>-Al<sub>2</sub>O<sub>3</sub> and SiO<sub>2</sub>-Al<sub>2</sub>O<sub>3</sub> were systematically evaluated. The SiO<sub>2</sub>-Al<sub>2</sub>O<sub>3</sub> flux system exhibited superior performance, yielding a cobalt-rich alloy containing 95.1 wt% Co and 3.2 wt% Ni, with only trace amounts of copper and iron.

Phase and compositional analyses using X-ray diffraction (XRD), inductively coupled plasma optical emission spectroscopy (ICP-OES), and field-emission scanning electron microscopy (FESEM) confirmed the formation of Co-Ni alloy phases. Lithium and aluminum were preferentially partitioned into the slag phase, enabling clean metal-slag separation.

This study integrated research results from both domestic and international sources to clarify the sources, occurrence characteristics, detection methods, and removal strategies of MPs in leachate, and discussed the complex pollutants on the surface of MPs. The research results show that 30% hydrogen peroxide has the best digestion effect in the pretreatment process of MPs. Fourier transform infrared spectroscopy is the preferred characterization method for MPs due to its cost-effectiveness and high efficiency; in addition, emerging technologies such as laser direct infrared spectroscopy can rapidly quantify MPs smaller than 20 micrometers. The removal of MPs is mainly achieved through physical separation processes, particularly membrane filtration. MPs have a large specific surface area, which can accumulate antibiotic-resistant bacteria and subsequently form biofilms. Aging further enhances surface roughness, increases the number of oxygen-containing functional groups, and enhances the carrier capacity of MPs for various environmental pollutants. Biofilms can promote the spread of pollutants through selective enrichment. Current research efforts face several limitations, including the lack of standardized detection methods, the scarcity of long-term monitoring studies, and the focus on single pollutants. It is necessary to establish standardized analytical methods, conduct in-depth research on the combined effects of multiple pollutants, and explore innovative strategies to utilize the unique properties of MPs to target the removal of environmental pollutants, such as through the engineering modification of biofilm microorganisms to turn waste into wealth in future.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"28 4","pages":"2753 - 2773"},"PeriodicalIF":3.8,"publicationDate":"2026-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148532281","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}

With increasing global use of biodegradable packaging, developing sustainable recycling methods such as pyrolysis has become a key priority. In this study, analytical pyrolysis hyphenated with gas chromatograph/mass spectrometry (Py-GC/MS) is used to assess the resource recovery potential of two biodegradable plastics, polylactic acid (PLA) and polybutylene adipate terephthalate (PBAT)-PLA blend. These packaging materials were characterized for their elemental composition, thermal stability and structure using different techniques. The efficacy of HZSM-5 in the selective recovery of specific chemicals from the plastics was studied at 400 °C, 500 °C and 600 °C. Acetaldehyde, 1,4-dioxane-2,5-dione, and 3,6-dimethyl- (<span>D</span>-, <span>L</span>-lactide-) were identified as major products from non-catalytic pyrolysis of PLA. At 500 °C acetaldehyde was enhanced compared to 400 °C and 600 °C, whereas ester compounds were the dominant products at 400 °C. The primary products from non-catalytic pyrolysis of PBAT-PLA blend included 1,3-butadiene, 3-butenyl adipate, bis-(butenyl) adipate esters and cyclopentanone. This showed that C – C bond fission and further free radical reactions play key roles in PBAT pyrolysis. In situ catalytic pyrolysis using HZSM-5 predominantly promoted the formation of monocyclic and bicyclic aromatic compounds across all investigated temperatures, while a more diverse product distribution was observed at 600 °C. Notably, catalytic pyrolysis of the PBAT/PLA blend produced mainly C₆–C₁₂ gasoline-range hydrocarbons, due to the shape selective activity of HZSM-5.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"28 4","pages":"3157 - 3176"},"PeriodicalIF":3.8,"publicationDate":"2026-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10163-026-02602-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148532275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We detail VOC sampling and analysis methodologies across wet, dry, and mixed plastic incorporation methods, critically evaluating their suitability for PMA’s complex emission profiles. Our synthesis identifies contradictory findings in the limited literature, with studies reporting emission reduction, increased toxicity or irritants, and negligible or compound-specific changes; inconsistencies largely attributable to methodological variabilities. Certain polymers (particularly polyolefins like PE and PP) are well-studied, while more hazardous but common waste plastics (PVC, ABS, PS) are conspicuously underrepresented. PMA construction may generate elevated hazardous fumes with potential novel toxicants from polymer decomposition, yet comprehensive occupational exposure data and field validation remain absent. Critical knowledge gaps include systematic emission inventories by plastic type and method, field monitoring studies, long-term emission behavior, and standardized testing protocols. Though landfill reduction and enhanced durability are acknowledged advantages, resolving these emission-related uncertainties is imperative.
