Hazardous waste disposal in Germany: a case study of the site in Billigheim, Baden-Wurttemberg
The disposal of hazardous waste is a very critical issue. It is associated with many risks. Efforts are made to minimise these by consistent legislation and by proper treatment of the waste. The goal of a hazardous waste disposal site, as described in this paper, is to ensure that hazardous waste is treated and disposed of in a way that does not harm human beings or the environment. To assure ...

The impact of an open waste disposal site on soil and groundwater pollution
A study has been carried out of a waste disposal site, located in the valley of a small creek, 3 km south of Canakkale city centre. The surface area of the site was around 101000 square metres, and the total amount of waste deposited at the site since 1990 was approximately 1001000 tons. The major risks of the dump are its closeness to the university campus area to the south, the airport to the ...

Hazard assessment of waste disposal sites. Part 1: literature review
A review of the literature and computer models from the perspective of hazard assessment approaches, particularly relating to the risk analysis of waste disposal sites, has been carried out. It was found that a comprehensive hazard assessment procedure covering all modules and sub-modules for landfill leachate does not exist. The same deduction also applies to landfill gas and degraded landfill ...

Role of final cover soil in regulating volatile organic compounds: emissions from solid waste disposal sites in developing countries
The objective of this study was to investigate the emission of Volatile Organic Compounds (VOCs) from solid waste disposal sites and their remediation at final cover soil. This research was conducted using field cover soil lysimeters placed at the surface of a solid waste dumping area and batch experiments in the laboratory. It was found that benzene, toluene, chloroform and perchloroethylene ...

Reduction of economic risks associated with the disposal of hazardous wastes in Hungary
Environmental risks are a growing public concern in Hungary. The threat of contaminated drinking water from abandoned and illegal hazardous waste disposal sites is receiving increased attention from citizens and from the environmental authorities. In respect to the problems of hazardous waste disposal, one of the most important objectives of Hungarian environmental policy is the enhancement of ...

Emission of volatile organic compounds from solid waste disposal sites
The emission of volatile organic compounds (VOCs) from a solid waste disposal site for municipal solid wastes was quantified. The VOCs contained in the landfill gas taken at the site were benzene, toluene, xylenes, ethyl benzenes, and trimethyl benzenes, while the concentrations of chlorinated compounds were very low. The concentration of benzene in the landfill gas samples ranged from below the ...

Special purpose mapping for waste disposal sites: Report of IAEG Commission 1: Engineering Geological Maps
This report results from work that was first proposed to a meeting of the International Association of Engineering Geology (IAEG), Commission No.1 held in Bratislava (Slovakia) in 1992. Following the publication of the Commissions report on Engineering Geological Maps (Engineering geological maps (1976) and reports on the description and classification of rock and soil and on recommended symbols ...

Field scale longitudinal dispersivities estimation in a karstic aquifer
To simulate contaminant advective transport it is required to provide dispersivity values to the models, values that are unknown in many cases. In this paper a methodology is presented to estimate longitudinal dispersivities at field scale, based on the monitoring of groundwater quality at an unconfined aquifer that is below a waste disposal site with no liners for groundwater protection, and by ...

An investigation of the surface and groundwater leachate from an old waste disposal site at Mamak, Ankara, Turkey
Mamak solid waste disposal site covers an area of approximately 0.5 square kilometre and the amount of waste it holds is around 13 × 106 m?. The amount of leachate measured through a weir at the toe of the body of waste is 164,000 m3? per annum. It is calculated that approximately 130,000 m? of this amount directly comes from the waste. Owing to the retention of precipitation by wastes, it takes ...

Identifying potential repositories for radioactive waste: multiple criteria decision analysis and critical infrastructure systems
An approach for the analysis and management of multiple criteria critical infrastructure problems is put forth. Nuclear waste management involves complex tradeoffs under uncertainty. Among all waste either generated by nature or human activities, radioactive nuclear waste is the most toxic to human health and difficult to manage: it is known that some nuclear waste material will be radioactive ...

Estimating national landfill methane emissions
This paper estimates national methane emissions from solid waste disposal sites in Panama over the time period 1990–2020 using both the 2006 Intergovernmental Panel on Climate Change (IPCC) Waste Model spreadsheet and the default emissions estimate approach presented in the 1996 IPCC Good Practice Guidelines. The IPCC Waste Model has the ability to calculate emissions from a variety of solid ...

Hazard assessment of waste disposal sites. Part 2: a holistic approach for landfill leachates
The review of literature and computer models described in Part 1 of this paper led the authors to conclude that a quantitative hazard assessment methodology does not exist, in holistic terms, for landfill leachate. Although there are various reports and models addressing different aspects of the methodology, they are not integrated and show different degrees of completion. This part of the paper ...

GHG emissions: an assessment at municipal solid waste disposal site in Indore, India
After ratifying the Kyoto protocol the assessment of anthropogenic greenhouse gases (GHG) inventories has become crucial for India. Municipal solid waste management system for city of Indore, India, has been evaluated for GHG emissions over a period of 41 years. Corresponding assessment of CO2, methane and N2O has been done on the basis of waste quantity and composition assessed for various waste ...

Greenhouse gas emission potential of the municipal solid waste disposal sites in Thailand
Open dumping and landfilling are the prevalent solid waste disposal practices in Thailand. Surveys on the disposal sites revealed the presence of 95 landfills and 330 open dumps. Methane emission potential at these sites was estimated by three methods. Results of the Intergovernmental Panel on Climate Change (IPCC) method, Landfill Gas Emission model (LandGEM), and closed flux chamber technique ...

A simple method to check for natural attenuation downstream of abandoned waste disposal sites
Evaluations of waste sites are based on the assessment of whether conditions for Natural Attenuation (NA) processes are favourable. A method is proposed as a first check for effects of NA in the groundwater emissions. For the application of the method, concentrations of the concerned substance and of a tracer must be available at observation wells at different distances from the source, ...

Installing a bottom liner in Lelystad Project - Case Study
Trisoplast is suitable for a wide range of subsurfaces, however huge, endlessly long or bumpy! The project at Zeeasterweg in Lelystad was all of the above. We laid a bottom liner under a waste disposal site of no less than 95,000 m2. Phase 2, another 51,000 m2, was completed in 2018. Slopes The refuse station at Zeeasterweg is where Lelystad’s businesses and residents go to dump their ...

A legal framework of financial liability of the nuclear power reactor industry in the field of waste management in Sweden and proposals for improvements
According to the nuclear legislation in Sweden, companies licensed to operate nuclear power plants have overall responsibility for safely managing all nuclear waste and to pay all expenses regarding final disposal. A committee was set up by the Government to explore the requirements in the present legislation, and if necessary, make proposals for improvements. The committee proposed that the ...

Clean production in stone cutting industries
The stone cutting industry uses high volume of water for cooling purposes and produces large volume of sludge. The disposal of both the wastewater and the sludge to a solid waste disposal site is costly and environmentally unacceptable. Wastewater and sludge from stone cutting industries in Jordan has been characterised and reused in various processes. Stone cutting industries can be modified to ...
