However, PB from lightweight packaging (LWP) waste is currently not comprehensively reintegrated into the paper value stream. To develop an adapted recycling process for PB from LWP, PB quantities, qualities, and fluctuations ranges in LWP are required. Currently, no sufficient database is available. Therefore, we developed a methodical approach and conducted a case study to access the PB potential in LWP sorting plants using manual analysis and sensor-based material flow monitoring. Differences resulting from seasonal variations, materials from different settlement structures, and fluctuation ranges in LWP composition over two weeks have been investigated. PB contents in the input of 6.5 wt% (ww) and 5.9 wt% (ww) were determined for winter and summer sampling campaigns, respectively. The PB product stream amounted to 5.7 wt% (ww, winter) and 4.8 wt% (ww, summer). Around 45 wt% (ww) of PB from the PB product stream was classified as misplaced by the consumer and should have been discarded in separate paper collections. Based on the determined PB quantities and qualities, a potential of usable and in the PB product stream available PB in LWP was determined. The technically available and usable PB potential in German LWP waste amounts to 89,000 to 100,000tons per year (average PB yield of around 65 wt% (ww)). The methodical approach can be adapted for sorting plant balances. The results can contribute to developing an adapted recycling process for PB from LWP.</p>","PeriodicalId":23969,"journal":{"name":"Waste management","volume":"189 ","pages":"196-210"},"PeriodicalIF":7.1,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142112755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

To this end, firstly, the percentages of AHP existing in the mixed waste bin (MWB) before and after the campaign were determined. A significant decrease in these materials was observed in the MWB (from 5 % to 3 % before-after the campaign). Secondly, the composition of AHP in the two types of selective collection bins (small red bins [SRB] located at the curbside and big red bins [BRB] for door-to-door collection in high-generation establishments such as nursing homes, kindergartens, etc.) was verified. Adults' diapers were the most abundant fraction (46 %-63 %), especially in door-to-door collection. The generation rate of this type of waste (17 kg/inhab-year) and the efficiency of each type of collection were also determined. Finally, the chemical properties (humidity, heating value, volatile solids, ashes, chlorides, bromides, metals, carbon, sulfur, oxygen, nitrogen, and hydrogen) of the AHP collected in the three types of containers (MWB, SRB, and BRB) were determined with the aim of proposing the possible recycling of this waste or energy recovery from it.

Landfill cover is vital for reducing leachate generation through reducing rainwater infiltration. Yet, the traditional cover with capillary barrier effects (CCBE) is only applicable in reducing rainwater percolation at its base in arid or semi-arid region. To solve this problem, a novel capillary barrier cover is proposed, which adds multiple gravel-segments to the traditional CCBE to form the zipper-shape interface between fine- and coarse-grained soils. Hydraulic response of this zippered CCBE is numerically investigated considering different gravel-segment sizes, drainage-ditch widths and climate conditions. It is found that the zippered CCBE has a lower water percolation than the traditional one by up to 57 %. It is because the capillary barrier effects along the right side-wall of gravel-segment leads to water accumulation and hence water percolation near its base, facilitating reducing water percolation using drainage ditch below the gravel-segment. Moreover, water percolation increases when the gravel-segment height exceeds 0.3 times thickness of fine-grained soil or the gravel-segment width increases, due to reduction of water storage in fine-grained soil. Under the recorded annual precipitation of 1235 mm in the semi-humid region in China, the annual percolation of the traditional and zippered CCBEs are 84 mm/year and 36 mm/year, respectively. Thus, the zippered CCBE might extent the applicability of the traditional CCBE from arid or semi-arid region to semi-humid region.</p>","PeriodicalId":23969,"journal":{"name":"Waste management","volume":"191 ","pages":"220-229"},"PeriodicalIF":7.1,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142677076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Integrating Hydrothermal Liquefaction (HTL) with anaerobic digestion (AD) can improve biomass efficiency and recovery of both energy (liquid fuels) and valuable nutrients, essential for achieving circular bioeconomy. Biogas digestate is rich in nutrients, and the HTL process can concentrate these nutrients in the solid phase, making the resulting product well-suited for agricultural applications. In this study, HTL solids were produced from biogas digestate using a continuous bench-scale HTL pilot plant to assess their potential as direct-use fertilizers. The optimal conditions for keeping contaminants within allowable limits in mineral products were identified by testing various reaction temperatures, with and without the use of a catalyst. The elemental composition of mineral products (2179 and 2181) showed high carbon varying from 51.61 and 48.41 wt%, phosphorus varying from 3.46 to 3.07 wt% and sufficient nitrogen contents varying from 1.19 to 1.13 wt%. Furthermore, carbon stability of 2179 and 2181 was measured to be 1.2 and 0.3, respectively, which indicated good quality of HTL mineral products. Organic contaminants and heavy metals in HTL mineral products obtained after biocrude recirculation cycles using the HTL pilot plant were found to be close to or below the allowed limits set by Danish legislation. Avoidance (EC50 1.62 %) and seed germination (EC50 21.37 %) tests of the mineral product indicated a moderate level of biotoxicity and a substantial plant growth stimulation potential. A maximum amount of 39 kg/ha for 2179 and 55 kg/ha for 2181 is suitable for field use without harming soil organisms. The phosphates recovery from mineral products into phosphorus-based fertilizers like struvite and hydroxyapatite using mild acids and bases as leaching agents showed around 90 % phosphates recovery and 70 % bioavailability. The synthesized fertilizers were characterized using X-ray diffraction (XRD) spectroscopy. Overall, HTL mineral products present a sustainable alternative for enhancing soil fertility, reducing reliance on harmful chemical fertilizers, and supporting both environmental and economic stability, thereby contributing to a circular economy.</div></div>","PeriodicalId":23969,"journal":{"name":"Waste management","volume":"191 ","pages":"Pages 203-211"},"PeriodicalIF":7.1,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142649062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Due to their high toxicity and carcinogenicity, effective treatment of BERs and BFRs is the key to achieve the environmental-friendly recycling of WPCBs. Recently, catalysis pyrolysis has proven an efficient and promising approach to removing and recovering bromides from WPCBs. The selection of catalysts and pyrolysis parameters mutually affect the debromination of WPCBs including products and mechanisms. However, there are few studies that focus on analyzing and summarizing the above aspects. Herein, this review first introduces types of catalysts (metals, oxides, hydroxides, molecular sieve, etc.) and figures out that metals are regarded as the most suitable catalysts for WPCBs debromination due to their high efficiency and easy to recycle. Then, the interactive effects of catalyst types and pyrolysis parameters on the debromination efficiency are analyzed, and it was found that temperature ranging from 500 to 600 °C, rapid heating rates, small-size samples and in-situ metals were more suitable for debromination. Moreover, a new idea of in-situ catalysis pyrolysis using self-compositions in WPCBs is highlighted, which point out that the defects of catalysts during the reaction process could promote debromination performance. This review summarizes the key knowledge about catalysis pyrolysis debromination from WPCBs, which will devote to the recycle WPCBs more efficiently and environmental-friendly.</div></div>","PeriodicalId":23969,"journal":{"name":"Waste management","volume":"191 ","pages":"Pages 191-202"},"PeriodicalIF":7.1,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142645070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

In the process of recycling waste photovoltaic laminated modules, decapsulation is a key step. Pyrolysis was considered as the common decapsulation technology, but it would cause problems such as loss of organic resources, producing pyrolytic carbon black and toxic gases. This paper reported a wet decapsulation technology. It employed the combined treatment of thermal field and the solvent of N-methyl-2-pyrrolidone to swell ethylene vinyl acetate for liberating the materials of waste photovoltaic laminated modules. Under the conditions of 170 °C and 30 min, the 3 cm × 3 cm-sized waste photovoltaic laminated module was completely decapsulated. The analysis of Fourier transform infrared spectroscopy indicated that N-methyl-2-pyrrolidone was grafted to ethylene vinyl acetate structure, and some new groups were generated, such as N–H and C = O. Calculation results of density functional theory showed that N atom and methylene were active sites in N-methyl-2-pyrrolidone. They could react with the cross-linked bridge and side chain of ethylene vinyl acetate to form N–H and C = O groups, which made ethylene vinyl acetate lose its viscosity and produce decapsulation effect.
