Probabilistic modelling of calcium leaching in a tunnel for nuclear waste disposal

Probabilistic modelling of calcium leaching in a tunnel for nuclear waste disposal

The structure which we study is a tunnel for radioactive waste disposal. The objective is to confine the waste in a deep geological formation to protect the environment from the radionuclides they contain. This confinement has to be guaranteed over large time scales (up to several hundreds of thousands years) without requiring maintenance. The waste is contained in packages of metal or concrete, depending on the nature of the waste. These packages are arranged in cells, being disposal cavities in the rock. Under the hypothesis of reversible storage, packages are simply stored in the cells. If the option of underground disposal is finally adopted, the cells, and the tunnels leading to them, will be sealed.

A study of Various Methods of Waste Disposal and Management in India

A study of Various Methods of Waste Disposal and Management in India

potentially useful materials, reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution (from incineration) and water pollution (from land filling) by reducing the need for "conventional" waste disposal, and lower greenhouse gas emissions as compared to plastic production. Recycling is a key component of modern waste reduction and is the third component of the "Reduce, Reuse and Recycle" waste hierarchy. Industries like glass, lumber, rubber tyres and paper manufacturers benefit greatly from recycled products. Shipbuilding industry also reclaims steel of old ships and vessels. E-waste is a growing problem, accounting for 20-50 million metric tons of global waste per year according to the EPA. TVs, monitors, mobile phones and computers are typically tested for reuse and repaired. If broken, they may be disassembled for parts still having high value. Other e- waste is shredded to ~100 mm pieces and manually checked to separate out toxic batteries and capacitors which contain poisonous metals. The remaining pieces are further shredded to ~10 mm and passed under a magnet to remove ferrous metals. Next an eddy current ejects non-ferrous metals, which are sorted by density either by centrifuge or vibrating plates. Precious metals can be dissolved in acid, sorted, and smelted into ingots. The remaining glass and plastic fractions are separated by density and sold to reprocesses. Plastic recycling is an irreplaceable way of reducing the burden of the ever increasing quantities of plastic waste in today’s world.

Solid Waste Disposal: A Choice Experiment Experience in Malaysia

Solid Waste Disposal: A Choice Experiment Experience in Malaysia

These findings may supply some direction in strategizing government policies related to solid waste management and disposal that are implementable and acceptable by all stakeholders in the country. The strong NIMBY syndrome and willingness to accept sanitary landfill at the expense of more land use identified in this study suggest that the authorities have to relook at the procedures on location choice to site the disposal facilities and that these sites should be further away from townships. However, the transportation costs have to be factored in as well in order to make the site location a feasible one for the waste disposal service providers at the same time. The study also reveals some form of labeling effect where the public chooses to shy away from incineration than sanitary landfill. Hence, the authorities may have to use more greener or neutral names for disposal technologies that might be brought into the country in the future.

ENVIRONMENTALLY RESPONSIBLE REPAIR AND WASTE DISPOSAL INVENTORY MODELS

ENVIRONMENTALLY RESPONSIBLE REPAIR AND WASTE DISPOSAL INVENTORY MODELS

Traditional inventory models involve different decisions that attempt to optimize material lot sizes by minimizing total annual switching costs. However, the increasing concern on environmental issues stresses the need to treat inventory management decisions as a whole, by integrating economic and environmental objectives. Recent studies have underlined the need to incorporate additional criteria in traditional inventory models in order to design "responsible inventory systems". This paper explores the problem of determining the optimal batch sizes for production and recovery in an EOQ (economic order/production quantity) repair and waste disposal model context. This paper assumes that a first shop is manufacturing new products as well as repairing products used by a second shop. The used products can either be stored in the second shop and then be brought back to the first shop in an approach used to reduce inventory costs, or be disposed outside the system. The works available in the literature assumed a general time interval and ignored the very first time interval where no repair runs are performed. This assumption resulted in an over estimation of the average inventory level and subsequently the holding cost. These works also have not accounted for switching costs when alternating between production and recovery runs, which are common when switching among products or jobs in a manufacturing facility. This paper addresses these two limitations. Mathematical models are developed with numerical examples presented and results discussed.

Biomedical waste disposal systems of health facilities in Ethiopia

Biomedical waste disposal systems of health facilities in Ethiopia

In this study, the result of bivariate analysis shown in Table 3 indicates that at a 1% level of significance, the status of using safe medical waste disposal method was significantly associated with facility type, managing authority, region, urban/rural, and availability of guidelines for waste management in the service area. This finding is in agreement with a study conducted in India which revealed that biomedical waste management practices were better among hospital staff in comparison with private medical practitioners and marginally higher among those in urban areas in comparison with those in rural areas (18). The management of healthcare waste is an integral part of a national healthcare system. The waste management system consists of all activities related to the handling, treatment, disposal, or recycling of waste materials. The purpose of a waste management system is to make sure that waste materials are removed from the source or location where they are generated and treated, disposed of, or recycled in a safe and proper manner (19). However, in this study, the multivariate logistic regression analysis revealed that general hospitals were 7.537 times more likely to use safe medical waste disposal methods than referral hospitals. Furthermore, primary hospitals, health centers, health posts, and medium clinics were 5.914, 4.335, 4.639, and 8.227 times more likely, respectively, to use safe medical waste disposal methods than referral hospitals (Table 4). As a result, a holistic approach to healthcare

solid waste disposal-unit 5

solid waste disposal-unit 5

(i) Waste disposal is as much a technical issue as a political one. For example, an elected representative, called a Corporator, administers a municipal ward, and is responsible for the general upliftment of the ward. But, generally, waste disposal is not considered a priority issue. However, our locality, and indeed, Bangalore is just awakening to the importance of waste disposal, and the Bangalore Agenda Task Force appointed by the State government has introduced a programme called the Swachha Bangalore. This programme involves door-to-door collection of solid waste. But, this is merely a temporary solution as the city, requires an integrated waste management system. In the main, for any programme to be successful, sufficient political and governmental backing is necessary.

Rural waste disposal issues within urban borders

Rural waste disposal issues within urban borders

The paper examines the waste management issues in the villages annexed to administrative-territorial units of the Romanian cities which have been frequently neglected by urban waste operators. The lack of waste collection services in such peri- urban communities favored the illegal waste disposal practices particularly prior to EU accession. The extension of waste collection services from main cities to such areas is compulsory in order to mitigate the environmental risks and the public health threats. The paper estimates the amounts of household waste susceptible to be uncontrolled disposed of by peri-urban villages in different geographical areas of North-East region with a particular focus on Neamt county. The paper points out that these rural settlements should receive the same attention concerning the municipal waste management services as the main urban areas. Traditional recovery of waste fractions at the household level (e.g., home composting) should be further promoted in such areas in order to avoid illegal dumping issue and to prevent the landfill of biodegradable waste as requested by EU regulations.

HAZARDOUS WASTE DISPOSAL GUIDELINES

HAZARDOUS WASTE DISPOSAL GUIDELINES

Purdue University is committed to providing a healthy and safe work environment for the campus community. The Purdue University Hazardous Waste Disposal Guidelines (HWDG) establishes a formal written program for the safe and compliant collection, storage, and disposal of hazardous waste. The term “hazardous waste” refers to any material designated as a hazardous waste by the Environmental Protection Agency (EPA). Hazardous waste may include, but is not limited to, undesired or outdated chemicals, spent chemical solutions, chemically contaminated debris or media, electronics devices, fluorescent lamps, and batteries. Determining if a chemical waste meets the regulatory definition of a hazardous waste can be difficult and requires specific training. Therefore, it is Purdue’s policy that all staff assumes that all chemical wastes are hazardous and must be managed by the Radiological and Environmental Management Department. Because of the technical nature of hazardous waste determination, the terms “chemical waste” and “hazardous waste” are used synonymously throughout this document.

Medical Waste Disposal (#22)

Medical Waste Disposal (#22)

Generally, medical waste treatment techniques fall into three categories: thermal, chemical, or irradiation. Traditional treatment methods discussed include steam sterilization and incineration. Incineration, a common and widely used method for medical waste disposal, has been impacted by the release, last year, of the EPA's final rules governing national standards for hospital incinerators and other incinerators of hospital, medical, and/or infectious waste. Stringent emission standards have been defined for nine specific pollutants and a mandated training and qualifications program for incinerator operators has been established. Current and innovative treatment methods will be discussed with emphasis on practical, cost-effective solutions.

Household Demand for Solid Waste Disposal Options in Malaysia

Household Demand for Solid Waste Disposal Options in Malaysia

Abstract— This paper estimates the economic values of household preference for enhanced solid waste disposal services in Malaysia. The contingent valuation (CV) method estimates an average additional monthly willingness-to-pay (WTP) in solid waste management charges of €0.77 to 0.80 for improved waste disposal services quality. The finding of a slightly higher WTP from the generic CV question than that of label-specific, further reveals a higher WTP for sanitary landfill, at €0.90, than incineration, at €0.63. This suggests that sanitary landfill is a more preferred alternative. The logistic regression estimation procedure reveals that household’s concern of where their rubbish is disposed, age, ownership of house, household income and format of CV question are significant factors in influencing WTP.

THE RADIOACTIVE WASTE DISPOSAL: THE CONTRIBUTION  OF ECONOMIC ANALYSIS

THE RADIOACTIVE WASTE DISPOSAL: THE CONTRIBUTION OF ECONOMIC ANALYSIS

We should consider here an aggregated indicator of the retrieval value of the radioactive waste at each date t . This indicator, denoted with W t is a function of three variables, all affected by significant uncertainty: W t = f ( P t , M t , Q t ) . For instance, P t represents the market value of radioactive materials contained in the radioactive waste, which is determined by changes in general economic parameters or in the nuclear industry. M t represents the state of the art in relevant technologies (the technological progress may be different when considering a radical or incremental innovation in the nuclear waste field). The last term, Q t describes the social and political factors that may also influence the value of the project, like public perception of nuclear risk, changing political climate, citizens trust in technological expertise, etc.

Waste Disposal in DOGEE

Waste Disposal in DOGEE

1. All waste chemicals must be identified by specific name or CAS number, the laboratory disposing of the waste, the principal investigator, and a contact person's name and phone number. All too often, students list only the chemical(s) they’re studying– and forget to include the solvent. This is especially important in non-aqueous solutions or in solvent-water mixtures (e.g., HPLC eluent) – the toxic risk posed by the solvent may outweigh that of the (minor) constituents of interest to the researcher. Label all bags, boxes or bottles with an indelible ink marker using a label provided by HSE. Make certain that the labels are securely fastened to the container. Mixtures should be identified as to chemical composition and concentration, using a designation such as “Nonhalogenated solvent waste: mixed organic liquids in primarily n-hexane Class 1A (flash point below 22.8C and

Informal Sector of Waste Disposal Management: Desirable or Redundant?

Informal Sector of Waste Disposal Management: Desirable or Redundant?

There is a need of incentivizing the informal sector to integrate with the formal sector. Two difficulties with incentive systems were pointed out by Terazono et al (2006), first, when the profit generated by remaining informal is larger than the incentive to become formal, the incentive system does not work; second, if illegally imported wastes are satisfactorily profitable, there is no need to collect domestic wastes. This means that international material cycles could create obstacles to the proper management of domestic E-waste. Despite these difficulties, subsidization seems to be a strong candidate solution, and all participants agreed that proper subsidies should be provided (Terazono et al., 2006).
