About the difficulties of classifying waste (and counting it) About the difficulties of classifying waste (and counting it)
A multitude of approaches exists to classify the various categories of waste. Waste can be sorted either by its origin (what activity has created it?), by its composition (what is it made of?), by the level of danger it poses to humans and the environment, or by the way it is managed and treated. Each of these approaches will lead to a list of wastes, and often those definitions are overlapping – yet another fact that complicates the collection ...

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...

Shipbreakers of Asia Shipbreakers of Asia
A few recent changes in national and international regulations provoked a massive drop in the tonnage of ships being broken up and major shifts in the shipbreaking market. Bangladeshi shipbreaking yards are, for example, gradually gaining ground on their Indian counterparts because Bangladesh does not enforce mandatory “gas-free for hot work” certification for oil tankers (Greenpeace).

BedZED (Beddington Zero energy development), location BedZED (Beddington Zero energy development), location
At Beddington, south of London, a housing development known as BedZED (Beddington Zero energy development) was designed from the start to produce little waste of any sort. It was built on a depolluted plot of land, previously used by industry, and recycled materials were used in its construction.

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...

Oil pollution in Azerbaijan Oil pollution in Azerbaijan
There are hundreds of abandoned oil wells in Azerbaijan, and thousands in Kazakhstan, many of which have been submerged by the rising sea. There are reports of big leaks into the water, killing waterfowl and fish. Thousands of hectares of soil on Azerbaijan’s Apsheron peninsula are unsuitable for agricultural use.

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...

Oil spill off the coast of Apsheron peninsula Oil spill off the coast of Apsheron peninsula
Thousands of hectares of soil on Azerbaijan’s Apsheron peninsula are unsuitable for agricultural use due to oil spills. The largest of these oil spills happened in May 1996. Oil extraction is happening off shore, in the Caspian Sea, and the oil is transported by pipelines.

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).

Conflicts and disasters - potential powder kegs (landmines and other explosives) Conflicts and disasters - potential powder kegs (landmines and other explosives)
The planet is scattered with hazardous or explosive leftovers from a succession of technical breakthroughs – be they military or industrial – just waiting to be washed away by a flood or mudslide or carried off by a hurricane. If disaster strikes these “powder kegs” multiply the danger to people and the environment (posing a particularly acute threat to already scarce water resources).

The graphic shows an outline of the areas within the Ferghana Valley which are subjects to disputes over water resources and borders, disputes between private and collective farmers, deforestation and overuse of pasture. The map also show areas of industrial pollution and chemical risks caused by badly maintained radioactive dumps, tailing containments and several working industrial facilities.

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 ...

Renewable energy production in Europe and Central Asia 2004 (heat production and electricity generation) Renewable energy production in Europe and Central Asia 2004 (heat production and electricity generation)
Hydropower, generation of electricity from dams in rivers, represents the majority of the energy produced, so far, with waste incineration - both from municipal and industrial sources, as a distant second. Other energy sources, such as biomass, windpower and solar power represents a very little share of the renewable energy produced so far. Energy consumption has been increasing in the region, since the 1990s, and with it the emissions of greenho...
