The reuse of mineral wastes is one of the most suitable solid wastes solutions. Throughout the world, the large of the granular aggregates used in constructions exploit natural mountain resources and rivers. Using mineral waste as a part of concrete, it can be helped to create a green environment and also contribute to sustainable development. Since the copper production process in the Sarchesh...

The basic characteristic of thermal power plants in the Republic of Serbia is that they use low-grade brown coal (lignite) as a fuel. Depending on the location of coal mines, lignite may have different properties such as heating value, moisture, and mineral content, resulting in different residue upon combustion. Because of several million tonnes of ash and slag generated every year, their gran...

London has traditionally exported most of its waste to former mineral workings in surrounding counties for landfill. Many of these sites are being filled and opportunities for new sites are limited. Virtually all waste reprocessing and recycling facilities, with the exception of textile sorting and some facilities for glass and organic waste composting, are outside London. The Mayor of London’s...

A solid phase extraction method for removing polar tritiated contaminants from tritium-containing waste oils has been developed. The composition of the degradation products present in the waste oil was determined. The results indicated that upon exposure to tritium gas, fragment methyl ketones, carboxylic acids, and lactones were the main polar products of the mineral-based oil oxidation. The n...

Researchers at the Geoengineering and Mineral Processing Study Centre of the Italian Research Council, have developed a database system integrated with a GIS (Geographical Information System),jor data collection on operational or closed waste disposal sites. This paper describes the objectives of the system, the data organisation, the structure of the database, the characteristics and functiona...

Mechanical behaviour of the waste body controls many aspects of landfill lining system design and performance, including stability issues and integrity of the geosynthetic and mineral lining components. Knowledge of the likely ranges of waste mechanical properties is required to assess potential modes of failure and hence to design the landfill engineering measures. This paper provides a summar...

The expansion of oil palm cultivation in Indonesia has been driven by a strong world demand for food especially fats and oils. Commencing in the island of Sumatra, it spread out to other island like Kalimantan, Sulawesi and Irian but not to the island of Bali which was already well developed. The role of palm oil in developing remote inland regions and improving the standard of living of rural ...

A synthetic Topopah Spring Tuff water representative of one type of pore water at Yucca Mountain, NV was evaporated at 95 °C in a series of experiments to determine the geochemical controls for brines that may form on, and possibly impact upon the long-term integrity of waste containers and drip shields at the designated high-level, nuclear-waste repository. Solution chemistry, condensed vapor ...

Evaluation of water quality of nine boreholes and three open hand-dug wells in a rural community in North Central Nigeria revealed relative abundance of cations Na > k > Ca > Mg > Zn > Pb and anions Cl(-) > PO4(2-) > SO4(2-) > NO3(-) in the boreholes and cations Ca > Na > K > Mg > Pb and anions NO3(-)  > PO4(2-)  > SO4(2-) > Cl(-) in the wells. The major contaminants exceeding SON and WHO permi...
