As such, the need for material diversification in pavement construction is essential to conserve the non-renewable natural resource deposits. This study assessed the use of Polyethylene Terephthalate (PET) waste and grounded tyre combined in varying proportions with aged bitumen modifier, and wax as a rejuvenator in the production of asphaltic concrete. A 10% polymer replacement level was maintained for all modified mix batches with three distinct proportions: 6%-PET:4%-GWT, 5%-PET:5%-GWT, and 4%PET:6%-GWT. The rejuvenator was added in percentages 1, 2, and 3 by the total mass of modified bitumen mix. Results showed that the penetration values of the modified bitumen mixes with wax fall between bitumen grades 20–60, indicating suitability in warmer climates. Ductility results indicate an increase in ductility upon modification compared to the control mix. The 6%PET/4%GWT samples obtained the highest ductility values (M2 = 23.5 cm, M5 = 12.5 cm, M8 = 22 cm, M11 = 24.25 cm). The highest softening point value (84.5°C) was obtained with M3 (5%PET/5%GWT/0%wax). The inclusion of wax as a rejuvenator led to massive increases in viscosity values compared to both the control mix and the mixes without wax. Flash and fire point results fell within the same range, implying that the modification and rejuvenation did not yield significant impact on the flash and fire point properties. Marshall stability results showed that no modified bitumen batch obtained stability up to the control mix. The highest flow value (5.9 mm) was obtained with the M12 (5%PET/5%GWT/3%wax) mix. This was about 47.45% higher than that of the control mix and 23.7% higher than that of the corresponding mix without wax. The study recommends material diversification as well as dosage variation as essential in the drive towards achieving optimum stability in asphaltic composites.","PeriodicalId":22919,"journal":{"name":"The Journal of Solid Waste Technology and Management","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135084049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a consistent and steep growth in India's dairy sector in the last few decades and now India is one of the major milk-producing countries in the world. Highstrength dairy wastewaters, if discharged without proper treatment, severely pollute the receiving water bodies. In this scenario 'Waste as a resource' concept has been gaining the interest of researchers. The present review delineates different technological advancements for treating dairy wastewater and compares which is the better option in terms of sustainability. In the aerobic process, advanced bioaugmented systems which use bacterial and fungal consortia were found to be effective and sustainable with biological oxygen demand removal of 78.7% and 74.7%. Physio-chemical methods using natural coagulants like Moringa oleifera (MO) and pomegranate peel powder were also found to be effective with 81.8 % nitrogen removal from dairy wastewater treatment. Phytoremediation using water fern (Azolla pinnata R. Br.) was found to be efficient with dissolved solids reduction efficiency of 71.56 %. The fluidized bed anaerobic reactor unit was found to generate a biohydrogen content of 35.72±9.43% when the OLR was 53.25± 7.81 kg. COD m– 3 d–1. Microbial fuel cells treatment of real dairy wastewater (RDW) using Shewanella algae (MTCC-10608) has generated maximum current density and power density of 141 mA/m2 and 50 mW/m2 respectively. These two technologies are better sustainable options for dairy wastewater treatment since waste to energy aspect is satisfied.","PeriodicalId":22919,"journal":{"name":"The Journal of Solid Waste Technology and Management","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135084184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, such a situation must be accompanied by the development of well-established management systems starting with the knowledge of MSW quantities, its quality and characterization and ending with a suitable landfilling technique. This work aims to characterize Egyptian municipal solid waste generated from two cities in Great Cairo, where 45 samples were collected regularly. The research was carried out by researchers in the Chemical Engineering Department at Cairo University and selected undergraduate students from October to December 2020. The collected MSW was characterized by evaluating the quality and quantity of generated waste. Selected properties considered were: composition (including the organic fraction, papers, plastics, textiles, metals, glass, and others), density, moisture content, calorific value, and Carbon Hydrogen Nitrogen Sulfer (CHNS) chemical elemental analysis. The results obtained showed that the organic fraction was dominant to other fractions (4287%) and the carbon content was more than 47% and the calorific values to range between 4360-12277 kJ/kg. The results obtained were used as a base for a waste management proposal, either from mass recovery for highrecyclable samples or energy recovery for high calorific value waste. In other circumstances, waste-to-energy WTE processes were recommended as a promising solution to developing countries in the world where the energy demand is essential for the life.","PeriodicalId":22919,"journal":{"name":"The Journal of Solid Waste Technology and Management","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135084036","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A vital tool for evaluating waste management options and planning sustainable approaches is life cycle assessment (LCA). LCA provides an effective means of assessing system expansion, encompassing the environmental effects of primary production, recycling processes, and waste management. Recent years have witnessed extensive utilization of LCA to evaluate the environmental performance of thermal waste-to-energy (WtE) technologies, such as incineration, co-combustion, pyrolysis, and gasification. These studies have primarily focused on key elements, including goal and scope definitions, technology parameters, and modeling principles. Furthermore, these investigations have explored the intricate interactions among various factors, including functional units, system boundaries, temporal and geographic scopes, waste composition, technology specifics, gas cleaning, energy recovery, residue management, inventory data, energy/mass calculations, as well as energy substitution and capital goods. This comprehensive review offers a comprehensive overview of the assumptions and modeling techniques employed in existing literature on waste-to-energy LCA. It also provides valuable recommendations to enhance future LCA studies on waste-to-energy. In summary, this review paper provides a comprehensive overview of the assumptions and modeling techniques employed in waste-to-energy LCA studies. It emphasizes the significance of LCA in evaluating the environmental impacts of waste management and offers valuable insights to advance research in waste-to-energy LCA.","PeriodicalId":22919,"journal":{"name":"The Journal of Solid Waste Technology and Management","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135084165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Secondary data on sanitary status of the region was collected followed by collection of primary data on structure of toilets constructed and sanitary practices from households and village level institutions through a questionnaire-based survey. Ground water samples used for drinking in the surveyed villages were tested for presence of E-coli using Compartment Bag Test kit following WHO norms. It was found that even after reaching near universal coverage of toilets, there have remained many pathways to contaminate the ground water. The findings have important implications on proper implementation of sanitation and drinking water supply programmes and steps to be taken to avoid contamination of ground water with faecal coliform even after an area has been declared as open defecation free. This will also help to identify the risk factors for designing water & sanitation safety plan to ensure water quality and improving public health and nutrition.","PeriodicalId":22919,"journal":{"name":"The Journal of Solid Waste Technology and Management","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135084169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
