Environment conservation is the common concern at all levels from local to global. Most of the recent environment problems and ill effects stem from ecological misappropriation and neglect to recognize the limits of ecosystem, its. Rapid population growth, low income, lowest health facilities, poor sanitation, lack of education. Personal and community hygiene poverty has enhanced the incidence ...

We study favoritism in public procurement of cleaning service contracts in Sweden 1990-1998. Cleaning services are a low-tech, clearly defined product with easy entry and no ex-ante quality differences. We study a period where the law allowed municipalities high degrees of freedom in choosing the winner. In our data, the lowest bid does not win 61% of the time, and municipalities pay on average...

Plastics wastes from a municipal solid waste (MSW) plant have a high-energy content and are suitable for fuel generation. Thermal cracking is one of the possible ways to obtain petrochemical feedstock from polymer wastes. Municipal waste plastic of LDPE conversion to kerosene grade fuel experiments were carried out under atmospheric conditions at temperatures between 150 ̊C and 420 ̊C. Low densit...

The aim of the study was to investigate the impact of municipal solid waste incinerator (MSWI) bottom ash (BA) codisposed with municipal solid waste (MSW) on landfill stabilization according to the leachate quality in terms of organic matter and nitrogen contents. Six simulated landfills, that is, three conventional and three recirculated, were employed with different ratios of MSWI BA to MSW. ...

Nineteen bottled water products were purchased from stores in Potsdam and Wappingers Falls, New York and analyzed for 71 inorganic elements by inductively coupled plasma - mass spectrometry (ICP-MS). The wide range in elemental concentrations observed suggests considerable variation in source water composition, processing, and treatment. Comparison with samples from a typical small municipal wa...

A nutritional requirement for the lipase production by Pseudomonas aeruginosa strain was investigated. The bacterial strain was isolated from municipal sewage and it was culture with different nutritional composition. The maximum lipase activity was obtained with maltose as the sole carbon source 6.5 Uml, followed by lactose 4.6Uml . The various salts used the best results were observed with ca...
