More than 167,000 m of mixed waste, waste that contains both chemically hazardous and radioactive components, are in the known inventory at DOE sites that formarly produced nuclear defense materials. The inventory contains both mixed low level wastes (MLLW) and mixed transuranic wastes (MTRU). Site cleanup and decommissioning activities during the coming years are expected to nearly double this...

Introduction: Today, the infectious wastes of hospitals are considered as a public health problem. Considering the huge amounts of hazardous wastes and the disadvantages of incinerators, we need to investigate the non-combustible devices involved in biochemical treatment. This study was carried out with the aim of evaluating the cost-effectiveness of infectious wastes devices. Materials and Me...

Between 1996 and 2002, the Swedish import of so-called yellow waste for energy recovery increased. The import mainly consisted of separated wood waste and mixes of used wood and paper and/or plastics that was combusted in district heat production plants (DHPPs). Some mixed waste was imported to waste incineration plants for energy recovery (10% of the import of yellow waste for energy recovery ...

olid waste” refers to the refuse , the solid and semi solid waste matters of a community except the night soil . Solid waste contains organic as well as inorganic matters . Solid waste management includes the entire process of dealing with solid waste ,starting from the collection from the primary source to ultimately disposing off it hygienically, so that it may not be a nuisance or create any...

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 disposal and treatment of wastes generated in the leather industry has been the focus of several studies around the world. They intend to meet environmental legislation and make the process environmentally and economically viable. The anaerobic digestion process, which occurs in steps that involve acid and methane forming bacteria, can be an alternative since it turns the waste into renewab...

Many scholars have argued that systems for treating waste impede organizations from preventing waste in the first place. They theorize that “end-of-pipe” (EOP) treatment diminishes the incentive to avoid creating waste in the production process and obscures the information necessary to devise prevention techniques. This prediction has been accepted widely, influencing both policy and practice, ...

As the generation of industrial wastes increases, waste treatment is steadily becoming a serious economic and environmental issue. Existing waste has mainly been treated by landfilling after incineration. A shortage of landfill sites necessitates waste management alternatives other than traditional incineration and landfill. This paper focuses on a cost-benefit analysis that evaluates the econo...

France’s policy on waste, like its environmental policy in general, is strongly influenced by Community policy. It has progressively diversified its objectives: public hygiene, security, reduction in the environmental impact of different treatments and, more recently, prevention and recycling. These main orientations are contained in the July 15 1975 law amended by the July 13 1992 law on elimi...

Laboratory scale biological trickling filters and three-phase airlift bioreactors have been studied for the elimination of methylene chloride (or dichloromethane) vapors from waste air, and the results used herein for the design of small industrial-scale reactors. The conditions chosen for scale-up were an air flow rate of 100 m3 h-1, a methylene chloride inlet concentration of 2 g m-3, and a t...
