This project deals with curating a new methodology for disposing e-waste containing lead through a deep geological repository. The lead waste would be buried few meters below the ground level in an enclosed container, thereby preventing interaction between its surroundings. This particular idea was derived from the disposal of nuclear waste through a similar procedure using deep geological repository. The procedure is also suggested to be one of the safest methods for disposing nuclear wastes. Lead waste from electronics tend to contain harmful acids which can contaminate the environment leaving behind harmful residue. The various steps needed for the establishment of a deep geological repository have been studied. The conventional method for disposing e-waste containing lead was to dump it in a landfill which could result in an environmental threat. This indicates that the successful implementation of the current project can be of great advantage for developing countries to have a method of safe e-waste disposal for lead which may cause lesser environmental damage.","PeriodicalId":14393,"journal":{"name":"International Journal of Waste Resources","volume":"9 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79093912","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}

During 1961-2011, the urban population was increased from 18 to 31.2% (Census of India, 2011b). India which is an agriculture-based economy is shifting towards service-oriented country as more of the population is shifting towards urban areas. Due to diverse geographical and climatic regions the people living here have different consumption and waste generation patterns. Towards sustainable urban development efficient municipal solid waste management is a vital constituent. Municipal solid waste management includes source segregation of waste, storage, collection, relocation, carry-age, processing, and disposal of solid waste for lessening its harmful impact on environment. Unplanned and short-term developmental plans increases industrialization and urbanization in the Indian Himalayan Region (IHR) and have led to tons of solid waste being sent to dump-yards and remained untreated. Due to this, solid waste management is becoming challenging issue in the IHR. In this review, various challenges and issues of solid waste management and probable solutions are suggested, particularly for the IHR.","PeriodicalId":14393,"journal":{"name":"International Journal of Waste Resources","volume":"10 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85315790","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}

Excessive growth of filamentous bacteria may cause, less dense floc structure, poor sludge compaction, slow settling, and wash-out solids from the final clarifiers. Sludge volume index (SVI) is an unknown method and the most appropriate parameter to express and estimate the settling characteristics of the sludge. The use of chemical materials to increase the volume of sludge is custom, but these methods are expensive and are not a green process. In recent years, the use of integrated treatment methods such as the use of magnetic fields (MFs) with biological methods, to accelerate the growth of microorganisms has become common. Methods: In this case and control study use of MFs (from 0.19 to 3.21mT) to decrease SVI (30 minutes time to settling) or enhancement of sludge, considered. Results: Based on the result of this study by increased the intensity of MFs, a decrease in SVI (0.03 to 53 percent) happened statistically. Conclusion: One of the main, physical, and practical methods to reduce the huge volume of sludge by decrease SVI in WWTPs can be used by applying MFs.","PeriodicalId":14393,"journal":{"name":"International Journal of Waste Resources","volume":"32 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78014229","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}

The specific objectives were to identify the socio-economic differentials of poultry waste users on the management pattern of poultry waste in the study area, examining poultry waste management and utilization techniques and their determinants in Afijio Local Government Area of Oyo State, Nigeria, Analyzed the impact of poultry waste utilization on yield and revenue of the respondents in the study area. A random sampling technique was used in selection of respondents. A total number of 104 respondents were randomly selected for this study through the use of structured questionnaire. Description statistics, Gross Margin analysis and cobb-Douglas production function were used as analytical techniques. The socio-economic characteristics of the respondents revealed that an average poultry farmer in the enterprises were between 41-50 years which means most of the farmers were in their active age and majority of the poultry farmers were male (52.90%). Majority of the poultry farmers had formal education (96.2%) while few had non-formal education (3.8%) this implies that majority of the respondents were literate 62.50% claimed they remove waste between 2-3 days interval. The variable that have significant relationship with poultry waste impact of respondents include: waste removal day interval significant at 5% level but had a negative relationship with poultry waste impact which implies that as the period for waste removal extends, there was a negative impact on the environment and performance on the poultry birds thus resulting to low output, purpose of rearing birds, years of experience and ingredient that increase/ decrease waste smell are all significant at 1% level of significance respectively. The enterprise in the study area is not a bias one because ratio of male to female is 1:1. The following are recommended: farmers should be encourage to increase hygiene by doing frequent sanitation so as to reduce the chances of diseases infestation, the farmers should be advised to attend waste management and health programme to support year of experience.","PeriodicalId":14393,"journal":{"name":"International Journal of Waste Resources","volume":"3 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78439360","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}

The presence of waste and municipal waste from industrial areas raises environmental concerns. Therefore, there is a need for new and optimal tools and methods to reduce the negative environmental and economic consequences. This research presents a new and optimal method to support industrial producers in various fields, especially food, to manage industrial waste as much as possible. The approach of this research is to provide an optimal structure of circular economics based on game theory that determines an adaptive decision structure based on fixed risk assessment and current knowledge. Adaptive decision-making structure based on game theory in the structure of the circular economy is a structural process for learning, improving understanding and finally adapting management decisions in a regular and efficient manner with the aim of reducing uncertainty during the management period. This research, by explicitly recognizing situational developments and improving decisions through learning, has great potential to meet future challenges in managing industrial risk and waste. This approach has been proposed as a way to re-evaluate risks and provide more adaptive and flexible management measures to strengthen infrastructure in the face of change. Sequential and adaptive updating of game theory is considered to reduce uncertainty and provide a decision management system. Finally, the proposed comparative decision-making method with a criterion based on a residential community as an industrial project in Tehran is shown to examine its feasibility and effectiveness in managing evolving risks. The results of this study show that changes in risk and vulnerability increase future risks for society and such risks can be managed with adaptive decision management system.","PeriodicalId":14393,"journal":{"name":"International Journal of Waste Resources","volume":"95 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76724688","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}

In animals including humans, there are different processes such as ingestion, absorption, etc through which they enter into the body. When heavy metal accumulates at a higher rate than the discharge then they become harmful for the animal. Anthropogenic activities of humans are the major cause of contamination of the environment and of medium-size cities. Burning of the fossil fuels, mining, and use of the chemical substances in the crop, etc. are the parts of anthropogenic activities that contribute pollutants in the environment. Toxic metal elements like cadmium along with the nutrients also uptake by the plant and accumulates in over time resulting in infections. The production and quality of crops and atmospheric conditions can be influence by high concentration of heavy metals. To avoid the toxic effects of heavy metals, plants developed several mechanisms due to which severe toxic elements excluded, retained inside the root, and change into the physiological tolerant forms. The contamination by the heavy metal elements is the major concern due to raising the demand for food safety. In this review, we have discussed the severe effect of heavy metal on productivity and interference of metal elements with a particular biochemical process inside the various crop plants that make unable to plant for the tolerance of high level of heavy metals present in environmental soil.","PeriodicalId":14393,"journal":{"name":"International Journal of Waste Resources","volume":"12 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91542917","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}
