India’s compound annual growth of plastic consumption has been around 7% for a decade. Despite this significant growth, there has not been a comprehensive study of Indian plastic flows since 2000. This work presents a 20-year update, detailing plastic production, consumption by all plastic types and sectors, and the overall material flow for 2018–19 to fill the gap in the data on post-consumer plastic flows. The analysis reveals a total plastic production of 19.3 Mt, 22% of which is Polyethylene as the most wildly used plastic. The total mass of plastic in products distributed in various applications is 23.9 Mt. Key sectors for plastic consumption are Packaging (30%), Textiles (17%), and Buildings and Construction (16%). Plastic waste generation is 15.5 Mt, primarily from packaging and textiles. Only 13% of this plastic gets recycled, 46% is mismanaged, and the rest incinerated or dumped. The study’s unique nationwide, mass-balanced, transparent approach offers a rigorous reference point for decision-makers. Yet, the lack of reliable data is the main barrier to design, implement, and monitor of policy interventions.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"26 6","pages":"3584 - 3595"},"PeriodicalIF":2.7,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10163-024-02060-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142193051","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}

This study optimizes heat treatment conditions for NCMs focusing on cathode materials and the current collector. The optimal parameters of 280 °C, 2 h, and 60 s were identified through systematic discharge, disassembly, crushing, and sorting processes. Precious metal recovery rates exceeded 90%. Thermogravimetric-thermal differential analysis at 400 °C revealed the complete removal of bonding agents between the electrode materials. A comprehensive cost analysis was conducted using a mathematical model for retired power batteries revenue, scrutinizing the consumption costs and benefits of pyrometallurgical, hydrometallurgical, and physical recovery processes for NCMs. The input–output efficiencies were 6.56%, 28%, and 23%, respectively. This study supports the viability of physical recycling for a future mechanical–chemical combination approach to reduce production costs and environmental impacts.

Accurately estimating the types, quantities, and distribution of solid waste is essential for effective waste management. The methods and processes for managing waste in any city, including collection, transportation, treatment, and disposal, rely heavily on accurate estimations of waste quantities. These estimates are in turn influenced by various factors, including socio-cultural, economic, environmental, political, and technological factors. The research aims to identify specific social and spatial factors that influence solid waste generation in municipal cities of the present times through a literature study. It then undertakes the study of a selected area in the city of Cuttack, Orissa, India, as a case study and formulates a model for quantifying solid waste based on the measurements of derived indicators. The research utilizes both primary and secondary data to achieve its objectives. The analysis revealed that factors such as monthly family income, house occupancy, and occupation have a strong positive correlation with the quantity of solid waste. Conversely, factors such as educational qualification and the incentive system provided to citizens exhibit a negative correlation with the amount of solid waste generated. Based on these factors, the model derived will facilitate the accurate estimation of solid waste generated in similar contexts, thereby aiding efficient waste management. By conducting this case study in Cuttack City, we aim to contribute to the existing body of knowledge on solid waste management in India and provide a comprehensive understanding of the factors affecting waste quantity.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"26 6","pages":"3495 - 3508"},"PeriodicalIF":2.7,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142193082","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 aims to evaluate the applicability of traditional chemical characterization methods for banana pseudostem, guava seed, and orange bagasse. An analysis of extractives removal time and sugar solubilization during this process was performed. The residues were evaluated based on the cellulose, hemicellulose, lignin, extractives, and ash contents, in addition to the holocellulose and α-cellulose fractions, followed by FTIR spectroscopy. Acid-soluble lignin was evaluated by UV–visible spectrophotometry with different extinction coefficients and wavelengths. The results showed that extractives’ removal for 4 h was sufficient for all materials, and a varied composition was observed among the biomasses. The guava seed had the highest lignin content, 41.66%, banana pseudostem had 33.97% cellulose, and orange bagasse had a high extractive content, 60.78%. The mass balance for all biomasses was above 92%, which suggests the applicability of such chemical characterization methods for fruit residues. A significant influence of different parameters in the determination of soluble lignin was observed. Thus, the present study serves as a basis for future research on the use and application of fruit residues, since there are no specific and complete studies on its characterization; including the evaluation of a greater number of plant varieties to obtain more representative results.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"26 6","pages":"3554 - 3570"},"PeriodicalIF":2.7,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142193083","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}

A comprehensive understanding of current practices and perceptions of solid-waste management at this level is crucial for making informed decisions and establishing an integrated, sustainable waste-management system. Rawalpindi, the fourth most populous city in Pakistan, faces obstacles in infrastructure development and the effective delivery of utility services, including solid-waste management, due to its rapidly growing population and unplanned expansion of peri-urban areas. While limited studies have explored household solid-waste-management practices in urban centers, peri-urban zones have been largely overlooked. This study focuses on comprehensive assessment and comparison of household waste management under both public and private sector systems in the peri-urban areas of Rawalpindi. The data collection was done employing a household survey and cross-sectional questionnaire, utilizing a simple random sampling technique. Analysis involved cross-tabulation and chi-square tests. The results indicate that the private sector outperforms the public sector in waste management operations. However, there is a minimal difference in waste segregation activities between households under public (46%) and private (54%) sector waste-management systems. Residents generally perceive waste, under both waste-management systems, as esthetically unpleasant and harmful to health, with 21.7% considering waste negatively compared to 11.7% who hold a different view. Our findings suggest that socio-demographic characteristics significantly influence household waste practices and perceptions in peri-urban areas of Rawalpindi, particularly under different waste-management systems. There is an opportunity for improvement in waste segregation at the household level through targeted awareness programs, aiming to foster the development of a sustainable waste-management system.</p></div>","PeriodicalId":643,"journal":{"name":"Journal of Material Cycles and Waste Management","volume":"26 6","pages":"3535 - 3553"},"PeriodicalIF":2.7,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142193084","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}

In the 2-year application, the effect on CO₂ respiration disappeared after 30 days, with no significant change in microbial biomass. Initial applications of LD stimulated microbial activity, but high dosages in prolonged applications tended to increase stress factors on microbial communities.

This paper aims to study the mechanical behavior, petrography and microstructural analysis of mining waste recycled bricks produced in a full-scale research on sustainability in civil construction. Mechanical tests (compaction, compressive, and tensile strengths) were carried out. A petrographic examination according to international standards was conducted. Complementary scanning electron microscopy and energy-dispersive X-ray spectroscopy analysis were performed. Mechanical tests showed that the addition of red mud can improve compressive strength by over 10% while the addition of fly ash does not show any improvement on the compressive strength. The petrographic characterization showed minerals thermally altered due to the temperatures reached in the brick manufacturing process and isotropic matrix showing glassy materials. The textural homogeneity (well-dispersed grains in a compact matrix) in the thin sections studied could explain the improvement on the geotechnical behavior of the bricks.
