Waste at every stage Waste at every stage
The squares are proportionnal to the estimated amounts of waste generated by sector in 2002, in the OECD countries (in million tonnes). Waste is produced from the very beginning of the life cycle of a product, long before we as consumers are aware of it.

Mining and ore waste Mining and ore waste
Mining waste takes up a great deal of space, blights the landscape and often affects local habitats. By its very nature it can constitute a serious safety hazard. Poor management may allow acidic and metals containing drainage to the environmnent, it can result in contaminated dusts be spread by the wind, and can also pose a physical risk. Indeed, the failure of structures such as dams built to contain mining waste has lead to many accidental sp...

Mining waste generated from aluminium production Mining waste generated from aluminium production
The production of aluminium involves three main stages: mining bauxite ore, refining bauxite to alumina (Al2O3), and then smelting alumina to produce aluminium. Bauxite comes from open mines mainly located in tropical and subtropical regions. On average it takes 4 to 5 tonnes of bauxite to produce 2 tonnes of alumina, yielding 1 tonne of aluminium. The main solid by-product of the alumina extraction (Bayer process) is red mud and roughly 3 tonnes...

Energy production waste in selected European countries Energy production waste in selected European countries
Waste is a major environmental concern for the energy sector. Depending on the type of energy, the production process itself will generate substantial quantities of waste. The energy sector generates specific types of waste: waste from mining and upgrading coal and lignite (tailing); waste from oil and gas refining; combustion waste from thermal power stations; waste from air-pollution abatement devices and fi nally the components of the power st...

Mine and industrial site in Koshkar-Ata, Kazakhstan Mine and industrial site in Koshkar-Ata, Kazakhstan
Much of the area near Koshkar-Ata Lake in Kazakhstan, just off the shore of the Caspian Sea, has been severely polluted due to mining activities of uranium phosphate. The area is also affected from chemical plants and metallurgic industries. The pollutants are quickly making there way to the Caspian Sea.

Potential environmental hazards in the Caspian Sea Region Potential environmental hazards in the Caspian Sea Region
Oil slicks glittering on the surface of the sea and thousands of hectares of soil penetrated by oil leaking from abandoned wells are just part of the pollution that people living around the Caspian Sea must endure. In addition there are various industries, particularly chemicals and mining, large-scale irrigated farming and untreated household waste. Combined with the effects of the oil, all these forms of pollution have a serious impact on the w...

Ok Tedi mine Ok Tedi mine
The Ok Tedi mine is located high in the rain forest covered Star Mountains of Papua New Guinea. Prior to 1981 the local Wopkaimin people lived a subsistence existence in one of the most isolated places on earth. That was before the 10 000 strong town of Tabubil suddenly appeared in the middle of their community. The Ok Tedi mine was built on the world’s largest gold and copper deposit (gold ore capping the main copper deposit).

Mining in the Democratic Republic of Congo Mining in the Democratic Republic of Congo
In the DCR, thousands people earn their living from digging with bare hands and simple shovels to extract ore. They live with the constant risk of exposure to toxic and radioactive substances. Moreover they run a high risk of being buried by a collapsing tunnel, security measures being almost non-existent.

Radioactive, chemical and biological hazards in Central Asia Radioactive, chemical and biological hazards in Central Asia
The Soviet development model for Central Asia was based on building large-scale irrigation schemes enabling the region to become a major cotton producer and expanding the mining and processing industry. Industrial operations in the region paid little attention to the environment and public health, resulting in the accumulation of pollutants in the local environment. Today, not only active industrial facilities constitute a threat to environment, ...

Radioactive waste in Taboshar Radioactive waste in Taboshar
The Taboshar uranium mining site stands on the southern edge of the Kuramin Mountains close the Uzbek - Tajik border. The site consists of a non - rehabilitated open mine, dismantled production buildings, and three tailing sites storing 10 m tones of low grade processed uranium ore. The town of Taboshar with its 12000 inhabitants is only a few kilometers away.

Metal production in the South Kyrgyz mines of the Ferghana Valley Metal production in the South Kyrgyz mines of the Ferghana Valley
In the soviet period the industrial operations paid little attention to environment or public health, resulting in the accumulation of pollutants in the local environment. Because of their vulnerability to natural hazards, previous history of accidents, and their position along water courses and in the vicinity of towns and cities in transboundary areas, tailing dumps at both active and closed mining enterprises constitute an environmental as wel...

Mercury mining, uranium mining, chemical and textile industries, oil facilities and processing plants which contribute to the contamination of the soil with highly toxic heavy metals are recognized as environmental challenges in the region. Even though past spills and contaminations have caused tensions between the different countries of the region, officials do not consistently regard environmental pollution by existing facilities as a security ...

There is 1.5 million small-scale miners estimated to work within whole SADC region. Main countries for small-scale mining activities are Tanzania miners and Zimbabwe, where more people are involved in the small-scale, rather than in the large- and medium-scale mining industry.

Government revenues from diamond exports in Sierra Leone Government revenues from diamond exports in Sierra Leone
The government of Sierra Leone saw a total of USD 5.2 million (2004) in revenues from diamond related activities. This comes in the form of mining, dealer and export license fees and from export taxes. To feed some of the revenues back to poor communities, the Diamond Areas Community Development Fund (DACDF) has been set up, with an annual commitment of 25% of revenue from export taxes. The intention is that this money will be dedicated to commun...

Fossil fuel resources and oil and gas production in the Arctic Fossil fuel resources and oil and gas production in the Arctic
The Arctic has been opened up for increased exploration of petroleum, gas and mining activities. The Barents Sea, the Mackenzie Valley in Canada and the Alaskan North Slope, are the areas of chief interest at the moment. With increased temperatures and climate change, it is expected that the commercial intrest for more extraction and exploration will increase, as well as shipping of the products. As sea ice decreases, the shipping lanes will beco...

Unsustainable water withdrawals for irrigation Unsustainable water withdrawals for irrigation
The imbalance in long-term water budgets necessitates diversion of surface water or the tapping of groundwater resources. The areas shown with moderate-to-high levels of unsustainable use occur over each continent and are known to be areas of aquifer mining or major water transfer schemes.
