Thermal technologies for the treatment of waste are once again attracting interest, particularly in Europe and North Amerca, as landfill space becomes scarcer and landfill regulations become more stringent. Plasma technologies can be used to destroy waste at high temperatures, using electricity to convert waste into a fuel gas and an inert rock. The Plasma Arc Waste Destruction System’s (PAWDS)...

Measuring or predicting the distribution of oxygen concentration in waste rock underneath a soil cover is an important aspect of cover performance evaluation. The oxygen decay coefficient is a key parameter in the prediction. In the present study, a method calculating oxygen decay coefficient from oxygen consumption rate is developed. The decrease in oxygen concentration over time measured abov...

This study explores whether information disclosure can cause cooperation in a social dilemma, even when people can disseminate false information. In the past, illegal dumping increased in Japan despite the strengthening of penalties and surveillance laws, due to practical limitations in monitoring and surveillance. To resolve this, the tracking sheet used to trace the trading and processing of ...

Integrated management of solid waste is nowadays a requirement and, at the same time, a challenge for the conservation of civilization and life on the planet. The material and energy exploitation of solid waste already contributes to a great extent to the resolution of environmental issues in the advanced countries of the planet. Unfortunately, a signifi cant delay in the treatment of waste is ...

The integrated disposal of surface subsidence pits and surface solid waste can be realized by backfilling a surface subsidence area with a paste made from the solid wastes of mines, such as tailings and waste rock. The microstructures of these wastes determine the macroscopic properties of a paste backfill. This paper presents an experimental study on the internal structure evolution of pasty f...

The risk associated with waste exposure depends on the level of emissions arising from waste disposal and from the effects of these emissions on human health (dose-response). In 2007 an epidemiological study was conducted in two Italian provinces of the Campania Region, namely Naples and Caserta, with the aim of assessing the health effects deriving from exposure to waste. In these studies, the...

Introduction During the Cold War, the United States and the former Soviet Union amassed extensive nuclear arsenals in a race of intimidation. Rapid manufacture of nuclear weapons produced large amounts of radioactive waste, and both sides sought the easiest means for waste removal. Russia generally disposed of its nuclear waste by a convenient and expeditious method: dumping it into the Arctic ...

In developing countries, little information is available about solid-waste characteristics, determinants for adoption and performance-evaluation of municipal-waste management systems in Municipals. This study aimed: to characterize the municipal solid-wastes, collection, dumping evaluate efficiency reliability Municipal system. A total 200 households were randomly sampled interviewed. Data was ...

It has been a long since problem of waste treatment and their disposal. Waste management does create a major problem if it is not properly performed. Various problems including different side effects occur to the people where untreated or partially treated waste is disposed, thus care should be taken while waste management and disposal. It becomes more difficult a job to perform radionuclide th...
