Opis:
The viability of partial replacement of biomass feedstock by the refuse derived fuel (RDF) produced from the local municipal waste management facility was investigated. Therefore, over two years, several samples of the rejected fractions from the selective collection operations and the mechanical and biological treatment were collected at the waste management facility. These samples were characterized to evaluate the physical composition, proximate analysis, ultimate analysis, alkali metal and trace metal content, calorific, and chlorine contents. All data were statistically analyzed. Several important differences were found between the rejected fractions and biomass, namely moisture, volatile matter, and fixed carbon content. However, the calorific value is like the expected from common wood or forest wastes. Trace and hazardous elements were found to be below the standard for RDF. After the statistical analysis, it was found that not all parameters had a normal distribution. Non-parametric tests were performed and for all the parameters analyzed only moisture content, nitrogen, and hydrogen show to be dependent on the waste source. Overall, the results point out the feasibility to prepare RDF from rejected fractions to use as co-fuel in a biomass power plant.

Opis:
Khulna is the third largest metropolitan city in Bangladesh and a centre with intensive commercial and industrial activities. Rapid urbanization and increased migration of people from rural and coastal areas has put tremendous pressure on its existing solid waste management. The status of the existing municipal solid waste (MSW) management tiers such as generation, source storage, collection, on-site storage, transportation, and open dumping has been identified in this study. The daily generation of MSW is estimated as 520 Mg, of which food and vegetable wastes are the main components (79% on average). The major source of generated MSW is residential areas, which is 85.87% of total generation, whereas 11.60% in commercial areas, 1.02% in institutional areas, 0.55% in street sweeps and 0.96% in other areas. About 50% of total generated waste is disposed daily to the dumping site and the rest remains uncollected and unmanaged. Non-governmental organizations and community based organizations play an important role in primary collection, composting of organic wastes and medical waste management.

Opis:
One of the major problems human beings are confronted with in urban setting is the removal of urban waste. This problem has persuaded the urban authorities to use various tools such as Geographic Information System (GIS) to locate landfills. To do that, Sloan Digital Sky Survey (SDSS) has been used in which or multi-criteria decision making (MCDM) methods and GIS are combined. The selection of the burial place and landfill has great importance and different criteria must be considered. SDSS, using MCDM is able to investigate locating landfill using various criteria simultaneously and it determines its importance. This research aims at presenting suitable solution through using computer and GIS related to solid urban waste and their locating in Hamadan based on standard criteria. A comprehensive model based on GIS, to get the suitable burial place and landfill can help to save time and cost. The model of locating burial place of urban solid waste has been presented.
