Environmentalists worry that hazardous wastes produced in industrialized nations are being dumped in cash-starved developing countries--the countries with the least political or economic clout to resist and the fewest resources for managing these toxic imports. Imported waste can pose a serious threat to the health of human populations and ecosystems if not managed appropriately. In 1989, the i...

Survey results describing the levels and prevalences of zoonotic agents in 1,549 livestock waste samples were analyzed for significance with livestock husbandry and farm waste management practices. Statistical analyses of survey data showed that livestock groups containing calves of <3 months of age, piglets, or lambs had higher prevalences and levels of Campylobacter spp. and Escherichia coli ...

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...

This study was conducted to evaluate the quantities of medical waste generated and the factors associated with the generation rate at medical establishments in Taiwan. Data on medical waste generation at 150 health care establishments were collected for analysis in 2003. General medical waste and infectious waste production at these establishments were examined statistically with the potential ...

INTRODUCTION Above 150 mln. m 3 (~37.5 mln. tonnes taking into account of density coefficient as 0.25) of municipal solid wastes (MSW) are annually produced in Russia (Cherp and Vinichenko (1996; Korneev & Bukreev, 2001). Landfilling is still the most common way for disposal of MSW in our country (Table 1). However, nowadays, MSW management in Russia is undergoing drastic changes (closure of ol...

The solid waste materials in cities are the natural outcome of human activities. Most of our cities and municipalities in third world countries like India is a major concern of the government due to the health problems associated with improper disposal of waste. Several factors are considered in site selection for waste disposal. Provision of such system appears to be a major problem due to the...

Supercritical water oxidation provides a powerful means to transform toxic organic materials into simple, relatively inert oxides. Over the past decade, our understanding of the fundamental chemistry of this process has increased markedly. Many fascinating research papers are appearing from laboratories around the world, on the use of the technique for the decomposition of a variety of organic ...

health care wastes, which produce in most hospitals, laboratories and clinics, causes spread of dangerous and contagious diseases and are a serious threat to human health and the environment due to contamination and the losses caused by the lack of health care waste management. now days there are 4 common technologies for the disposal of hospital waste which is taken into consideration by the m...

1.0 Problem Statement The disposal of municipal solid wastes is one of the most serious problems facing Waste generation is on the increasing trend due to exponentially renders waste management as a significant problem. The solid waste generation (lb/capita/day) has been on increasing trend since 1980, with the curr New York State alone generates 8.4 million tons of municipal solid waste per ye...
