The calculated calorific value and chlorine content of the water-washed pyrolysis residue satisfied the quality standards for refuse paper and plastic fuel. Furthermore, the pyrolysis residue was heated in an inert gas atmosphere over 500 °C for 2 h. When the heating temperature was above 800 °C, the surface functional groups and the oxygen content were decreased significantly. In addition, the calculated calorific value of these heat-treated residues exceeded 20 MJ/kg. Therefore, although the quality of the solid fuel was lower than that of the waste tires, the heat-treated residues were comparable to the refuse-derived fuel obtained from combustible general waste. The hygroscopicity and surface hydrophobicity of the water-washed pyrolysis residue were decreased by heating above 800 °C.

Continuous awareness creation, training, repeated short presentations at staff meetings and staff inductions, and quality checks are cardinal to implementing an effective medical waste collection system. The average daily weight for the IV bag and syringe were about 0.5 kg and 0.3 kg, respectively. This translates to 0.8 kg of total raw material daily and about 4 kilograms weekly.

Employing a methodical survey, data will be gathered from a representative sample of rural households in Chhattisgarh. For data analysis, the structural equation modeling (SEM) method was used. These factors include perceived behavioral control (PC) (<i>p</i> = 0.045), subjective norms (SN) (<i>p</i> = 0.001), habitual behavior (HB) (<i>p</i> = 0.034), situational factors (SF) (<i>p</i> = 0.000), awareness (AW) (<i>p</i> = 0.000), and knowledge (KN) (<i>p</i> = 0.035). In addition, households’ intentions strongly influence their actual behavior in separating plastic waste (<i>p</i> = 0.000). However, attitude (AT) (<i>p</i> = 0.228) does not significantly affect these intentions. Overall, the results highlight that subjective norms, habitual behaviors, situational factors, perceived control, awareness, and knowledge play key roles in shaping household intentions, which then impact their waste separation practices. To guide policymakers, environmentalists, and community stakeholders in developing targeted interventions that enhance plastic waste separation practices at the grassroots level, promoting a more sustainable and eco-friendly living environment is important.

The disposal of fly ash is one of the challenges thermal power plants face, even though a part has been utilized in cement production. The current study is undertaken to address the issues mentioned above. The novelty of this study is the use of i) high-volume fly ash (Class F) as a replacement for fine sand up to 100% and ii) foam generated using a natural and environment-friendly plant species in foam concrete for design densities ranging from 900 kg/m<sup>3</sup> to 1500 kg/m<sup>3</sup>. The foam was generated using soapnut, a plant-based foaming agent. The paper reports the effectiveness of large-volume fly ash as a replacement for sand in terms of workability, dry density, compressive strength, pore-size distribution, water absorption, sorptivity, and drying shrinkage of foam concrete. The inclusion of fly ash in foam concrete prevented the coalescence of bubbles by providing a protective layer around bubbles and enhanced the concrete properties. Using fly ash as a sand replacement at a constant foam volume enhanced the compressive strength through pore-refinement, which was confirmed through microscopic studies. An increase in the fly-ash replacement leads to an increase in sorptivity and shrinkage due to the rise in paste volume, consequent to the reduction in the requirement of foam volume.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"27 3","pages":"1339 - 1353"},"PeriodicalIF":2.7,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143861130","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}

This study examines the evolution of waste generation and treatment in South Korea from 1997 to 2022, aiming to propose strategies for future waste management. By assessing the proportion of waste treated through incineration, landfill, and recycling, this research utilizes a ternary diagram for an intuitive visualization of the data. The ternary diagram method proves effective for regional comparisons of waste management practices and for tracking historical shifts. The study offers a detailed regional and temporal analysis of waste flows, also benchmarking South Korea’s waste management efforts against EU and OECD standards. Notably, South Korea’s approach to waste management has evolved markedly, shifting from 63.85% landfill, 7.12% incineration, and 29.04% recycling in 1997, to 10.23% landfill, 24.00% incineration, and 65.77% recycling in 2022.
