FOREWORD Plans for disposing of radioactive waste have raised a number of unique and mostly philosophical problems, mainly due to the very long timescales which have to be considered. While there is general agreement on disposal concepts and on the approach to establishing that disposal facilities are safe, consensus on a number of issues remains to be achieved. To assist in promoting discussio...

The liquid wastes produced during the processing of radioactive materials at the Savannah River Site were initially stored in large underground tanks constructed of carbon steel. These liquid wastes were generated from the Purex process (for producing plutonium) and the HM process (for producing tritium). The liquid wastes were designated as high-level wastes and lowlevel wastes. As the product...

On behalf of the International Solid Waste and Public Cleansing Association (lSWA), it is a pleasure to open this First Annual North American Waste-to-Energy Conference. Solid waste management has moved to the forefront of the environmental agenda. The level of activity and concern by citizens and governments worldwide has reached unprecedented levels. Nations are considering restrictions on pa...

in vietnam, municipal solid waste (msw) has being become increasing complex due to variety of reasons as the increasing quantity, changing composition of msw, rising public awareness and municipal administration policies among different cities and surrounding communities. there is not currently an efficient management system in place for facilities such as storage, collection, transfer, transpo...

The development and testing of a Web-based GIS e-learning resource is described. This focuses on the application of GIS for siting a nuclear waste disposal facility and the associated principles of spatial decision-making using Boolean and weighted overlay methods. Initial student experiences in using the system are analysed as part of a research project on teaching GIS concepts to large number...

Waste transfer-stations play an important role in a community’s waste management system, serving as the link between a community’s solid waste collection program and a final waste disposal facility. This study aims to estimate economic values of externalities related to waste transfer-stations in Israel. Most externalities are associated with local disamenities experienced by residents living i...

This study concentrates on designing a medical waste management system with a hierarchical structure, including a local government and a waste management planner. The upper-level seeks to design and control the waste management facilities by minimizing the environmental risks related to the disposal of medical waste. While the lower-level model is to determine the waste collection plans by only...

Every year, 4 billion pounds of waste are produced by health care facilities, and the amount continues to increase annually. In response, a movement toward greening health care has been building, with a particular focus on the operating room. Between 20% and 70% of health care waste originates from a hospital's operating room, and up to 90% of operating room waste is improperly sorted and sent ...

Shortage of land for waste disposal is a serious and growing potential problem in most large urban regions. However, no practical studies have been reported in the literature that incorporate the process of consumption and depletion of landfill space in urban regions over time and analyse its implications for the management of waste. An evaluation of existing models of waste management indicate...
