Background: The production of waste pollutants has become a major problem for many food and oil industries. However, oil wastes can provide alternative substrates for industry, which could help to solve environmental pollution problems. Furthermore, oil wastes can be used as substrates to produce unsaturated fatty acids, which are important for health. Objectives: The production of fatty acids ...

Almost all major nuclear operations produce residues containing radioactive materials; in reactor operations, for example, the fission products, new elements (such as plutonium) produced by neutron irradiation and the unfissioned nuclear fuel are all radioactive. Some of this material can be put to further use: useful radioisotopes, for instance, can be extracted from the fission products and p...

This paper discusses the present hazardous waste program of 3M Company (Minnesota Mining and Manufacturing Company). 3M's definition of hazardous waste and the company's position on hazardous waste disposal are first considered. The company position is that wherever and whenever the disposal of a waste material threatens the environment or public safety, then that waste should be considered a h...

wastes management law as a turning point in the view of iran's legal system towards the issue of wastes was approved by legislator authorities on 5/09/2004, with a two-starred agency, as a comprehensive law against harmful effects of pollution and problems due to wastes for their optimal management. in this paper, in addition to evaluating of the legal system governing on wastes management...

in turkey, it is known that, wastes of fisheries processing plants released to the environment and only a bit of that assessed as fish meal or fish feed by a few plant. it is expected that with the evaluation of these wastes which rich in nutrient content by converted to the various commercial products (chitin, protein hydrolyzate, carotenoprotein and pıgment extraction etc.) to be beneficial i...

Thallium is a highly toxic element and very rarely studied in the context of environmental hazards connected with zinc and non-ferrous metal industry. Microorganisms naturally existing in post-flotation and smelt wastes can participate in thallium release from waste deposits and can contribute to its dispersion in the environment. Twenty-one isolates were obtained from wastes of a non-ferrous s...

BACKGROUND Animal wastes are of particular environmental concern due to greenhouse gases emissions, odor problem, and potential water contamination. Anaerobic digestion (AD) is an effective and widely used technology to treat them for bioenergy production. However, the sustainability of AD is compromised by two by-products of the nutrient-rich liquid digestate and the fiber-rich solid digestate...

This study was conducted to evaluate temperature, gas, and leachate data at two landfills in similar climatic regions (Detroit, Michigan, USA and Asahikawa, Hokkaido, Japan) to determine the interrelations between heat production and resulting waste temperatures and gas and leachate levels in landfills under variable decomposition conditions. Significant temperature increases occurred under lon...
