The effective application of EPS is impeded by restrictions imposed by using conventional polymer-based synthetic geomembrane insulation ought for protection. Meanwhile, the production process of the geomembrane has detrimental environmental impacts, incurs high costs, and limits the utilization of EPS blocks in various applications. This research aims to create an innovative nanocoating substance using nanocellulose derived from agricultural residues to provide an eco-friendly alternative to geomembranes. The nanocellulose was extracted from four agricultural waste materials; sugarcane bagasse, banana fibers, rice straw, and spent-ground coffee; where each had a local percentage yield of 35 %, 25 %, 19 %, and 10 %, respectively. Based upon a technical criterion provided by the transmission electron microscopy (TEM) micrographs, the TOPSIS multi-criteria decision-making method was used to rank the sustainability of waste materials. It was found that sugarcane bagasse (SCB) is the most sustainable type with the smallest nano particle size. Nanocellulose extracted from SCB was characterized using X-ray diffraction (XRD), energy dispersive X-ray (EDX), nuclear magnetic resonance (NMR), and Fourier transform infrared spectroscopy (FTIR). The innovative nanocellulose coating primarily consisted of a nanocellulose mixture (SCB + water), polyvinyl acetate (PVA), and zinc oxide. Fourteen distinct formulas were obtained to identify the optimal proportions suitable for application on EPS surface with respect to the nano particle size, purity, and binding energy between the elements. It was found that the optimum formula consists of 42 % SCB, 50 % PVA, and 8 % zinc oxide.</div></div>","PeriodicalId":23969,"journal":{"name":"Waste management","volume":"191 ","pages":"Pages 135-146"},"PeriodicalIF":7.1,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142629309","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}

Insect-mediated bioconversion, particularly using black soldier fly (BSF) larvae, can offer a promising opportunity to convert the organic fraction of municipal solid waste (OFMSW) into protein-rich biomass. However, current regulatory restrictions do not allow the use of this substrate to obtain insect proteins for animal feed, prompting the exploration of other applications, such as the production of bioplastics. Here, we explored at laboratory scale an innovative and integrated circular supply chain which aims to valorize the OFMSW through BSF larvae for the production of biobased materials with high technological value. BSF larvae reared on this organic waste showed excellent growth performance and bioconversion rate of the substrate. The use of well-suited extraction methods allowed the isolation of high-purity lipids, proteins, and chitin fractions, which are building blocks to produce biobased materials. In particular, the protein fraction was used to develop biodegradable plastic films which showed potential for replacing traditional petroleum-based materials, with the possibility to be fully recycled back to amino acids. Socioeconomic analysis highlighted values generated along the entire supply chain, and life cycle assessment pointed out that lipid extraction was the most challenging step: implementation of more sustainable methods is thus needed to reduce the overall environmental impact of the proposed chain. In conclusion, this study represents a proof of concept gathering evidence to support the feasibility of an alternative supply chain that can promote circular economy while valorising organic waste.</div></div>","PeriodicalId":23969,"journal":{"name":"Waste management","volume":"191 ","pages":"Pages 123-134"},"PeriodicalIF":7.1,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142629311","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}

Here, we compared the short-term degradation of seven single-use items (e.g., shopping bags, take-away boxes), made from plastic and biodegradable materials, in both marine and terrestrial environments. Biodegradable items tended to degrade faster than their plastic counterparts, but this advantage occurred in less than half of the situations tested (6 out of 14 situations). Notably, biodegradable items degraded faster than plastic counterparts more often in the terrestrial (5 out of 7 items) compared to the marine (1 out of 7 items). Interestingly, biodegradable items made of plant-based materials, such as bagasse and cellulose, generally degraded more rapidly than plastic, while those made of polylactic acid rarely degraded faster than plastic.

Greenhouse gas emissions is the most commonly used environmental indicator in optimization, followed by the endpoint single-score indicator. A static deterministic model is often employed to formulate an LCO problem, while uncertainty and dynamic models are less frequently applied but cause concerns. To deal with multi-objective optimization, the ε-constraint method and non-dominated sorting genetic algorithm are popular. Waste LCO has been mainly applied to macro system planning, such as integrated municipal solid waste management systems, biowaste supply chains, waste-to-energy systems, and waste-to-resource networks, aiming to determine optimal waste allocation, facility capacity/location, technology choice, etc. It is occasionally used in optimizing process structure, operating conditions, blending ratio of feedstocks, and product development.

Crumb rubber, derived from end-of-life tires, has potential for various applications where resilience and elasticity are required. However, as highlighted by the upcoming ban on using crumb rubber granulate as infill for artificial turf in the EU, one of the most prominent issues, zinc leaching, urgently requires an effective solution. We studied a range of commercial polymer coatings as a zinc leaching barrier through batch and column leaching tests. This study demonstrates that coatings can reduce the leaching down to 1 % of that of uncoated rubber, reducing environmental risks while improving the prospects for continued use of crumb rubber in various applications. The physico-chemical relation between the coating structure and zinc leaching is elucidated for the most promising coatings by comparing the leaching results with FTIR, GPC and ¹H NMR analyses. The use of certain additives shows a cumulative effect to further reduce zinc leaching, while improving UV- and moisture stability. Thermal stability is controlled by the stability of the polymer base. These findings allow us to tailor the mechanical properties to various applications requiring specific elasticity and durability, while retaining the versatility and adaptability of crumb rubber in a range of scenarios. Additionally, the use of additives, typically cheaper than the polymer matrix, enhances the economic viability.

Results indicate that 31.7 % of sulfur migrates to the gas phase due to the thermal decomposition of organic-S and the reduction of high-valent sulfur to SO₂ by H₂ and CO. The total sulfur (TS) content in tailing slag (TSL) (1.96 %) is significantly higher than that in the roasted product (RP) (0.84 %), suggesting a tendency for sulfur migration into TSL. This migration is attributed to reactions between H₂S/COS and Fe₂O₃/Fe₃O₄, resulting in the formation of non-magnetic byproduct FeS.
