The generation of contaminated leachate remains an inevitable consequence of the practice of solid waste disposal in landfills. The collection and treatment of leachate have become common practice in order to prevent environmental pollution. Leachate treatment is highly dependent on the quality of leachate, which in turn is influenced by various factors including waste composition and operation...

The construction of the Project for High-intensity Proton Accelerator Facility(Figure 1). in Japan has been started this year. The Japan Hadron Facility of KEK1 and the Neutron Science Project of JAERI2 merged to this project. The purpose of this Joint Project is to pursue frontier science in particle physics, nuclear physics, materials science, life science and nuclear technology. Accelerators...

Landfill disposal and waste-to-energy (WTE) incineration remain the two principal options for managing municipal solid waste (MSW). One critical determinant of the acceptability of these options is the different health risks associated with each. In this analysis relying on published data and exposure modeling, we have performed health risk assessments for landfill disposal versus WTE treatment...

There is a substantial literature that examines trade-offs between money and health risks. This literature has shown that estimates of marginal willingness-to-pay (MWTP) for changes in risk can be inferred from a wide variety of market situations. Much of the work has focused on mortality risks in the labor market (W. Kip Viscusi and Joseph E. Aldy, 2003), but substantial work has also looked f...

Heat is a primary byproduct of landfilling of municipal solid waste. Long-term elevated temperatures have been reported for MSW landfills under different operational conditions and climatic regions around the world. A conceptual framework is presented for management of the heat generated in MSW landfills. Three main strategies are outlined: extraction, regulation, and supplementation. Heat extr...
