The waste water treatment plants are very unstable and the waters to be treated are ill defined. The command of those processes needs to be done with advanced methods of control and supervision. They have to take into account the bad knowledge of the processes. The most important situations that imply problems for the plant are listed. Parameters for comparison between crisis and normal situati...

Membrane assisted liquid extraction(MALE) technologies are gaining an important role as an extraction /separation technique for actinides and are being deployed as a  promising tool for remediation of nuclear waste generated in the reprocessing plant and other radioactive wastes containing a trace level of radionuclides. The present contribution outlines the classification of membrane assisted ...

This article examines the EU Waste Directive and the implications of recent European case law for its implementation at national level. In particular, we consider how the directive has been implemented in the United Kingdom and the potential effects this may have on the use of forestry by-products as a bio-energy source. The analysis reveals that it is still unclear whether bio-energy materials...

Municipalities introduced unit-based pricing (UBP) with the aim of achieving a decrease in household waste generation and for the replacement of unsorted waste with recycling. Although many studies have shown that UBP has a short-run effect on recycling, few works have tackled the long-run effect on waste generation and recycling. By using panel data for 665 Japanese cities over 8 years, we exa...

Waste management is a complex and detailed process that involves evaluation of certain important factors, such as a geological, geotechnical, hydrological, hydrogeological, climate, urban management, environmental, along with social, cultural, and psychological parameters. Unfortunately, in Iran, there is minimal evaluation of initial parameters and in some cases even don’t exist. The purpose o...

As the largest solid waste (SW) generator in the world, China is facing serious pollution issues induced by increasing quantities of SW. The sustainability assessment of SW management is very important for designing relevant policy for further improving the overall efficiency of solid waste management (SWM). By focusing on industrial solid waste (ISW) and municipal solid waste (MSW), the paper ...

background: we aimed to extract the histogram features for text analysis and, to classify the types of bio medical waste (bmw) for garbage disposal and management. methods: the given bmw was preprocessed by using the median filtering technique that efficiently reduced the noise in the image. after that, the histogram features of the filtered image were extracted with the help of proposed modifi...
