Conflict Minerals

Nowadays, it is the mobile terminals are so popular with various sizes ranging from tabloid to smartphone. Many mineralsare in great demand because they are the essential to the opponents of those popular electronics. “Conflict minerals”, mostly in the eastern provinces ofthe Democratic Republic of the Congo, are mined in conditions of armed conflictand human rights abuses, located from populated areas in remote and dangerous regions. Blood Diamonds filmed by Leonardo DiCaprio, can well exemplify the phenomenon of the mining conditions in some African district.

Those minerals would pass through the hands of numerous middlemen as they are shipped out of Congo, through neighboring countries such as Rwanda or Burundi, to East Asian processing plants.

The US and the Securities and ExchangeCommission (SEC) passed a set of strict rules which require manufacturers toreport from where they get its tantalum, tin, gold or tungsten in an attempt curb the import of tainted minerals. However, there are critics who hold that the root of the conflict is left out by the regulations.

Congo refutes NGO accusations against Chinese miners

Congolese authorities sprang to defend Chinese miners operating in the country, after a report published last week by Amnesty International singled them as the main cause of human rights abuses in the African country.

The document Profits and Loss: Mining and human rights in Katanga, highlighted serious abuses by local and foreign mining companies, singling out Chinese companies as the ones that have gone as far as violating locals’ basic rights.

However, the Democratic Republic of the Congo’s government has questioned the “underlying reasons” of why the global NGO devoted so much time to scrutinize Chinese firms.

After a media briefing this weekend, Minister Lambert Mende was quoted by AP as saying that mining companies in Katanga, Congo's copper belt province, were are of 30 different nationalities, and none of them offered “their employees and clients different conditions to the Chinese companies.”

He added Asian companies have played a key role in extracting the country’s minerals and acknowledged that China also imports significant amounts of cobalt and copper from the country, much of which continues to be extracted by small-scale miners.

But Amnesty argues that small operations, also known as artisanal miners, tend to use handheld tools, and often working in "terrible" conditions.

“Mining operations in the DRC have resulted in decades of abuse against artisanal miners and the neighbouring communities,” said Audrey Gaughran, Director of Global Issues at Amnesty International in a statement.

“The DRC authorities have not only failed to prevent mining companies and traders abusing rights, they have themselves violated human rights to facilitate mining operations."

When questioned by Amnesty International, several of the companies included in the report attempted to absolve themselves of any responsibility by highlighting the authorities’ involvement in the abuse.

“The failure of the DRC authorities to protect human rights does not let the companies off the hook for their own actions and omissions. Disturbingly, some companies pointed to police involvement in an attempt to legitimize their own contribution to human rights violations,” said Gaughran.

The DRC was the eighth largest copper producer in 2012, with an output of about 500,000 tonnes per year. The African country was also the largest cobalt producer during the same period, according to data from the US. Geological Survey.

New East Harbour to Boost Esbjerg Port Growth Potential

The Port of Esbjerg’s new Østhavn (“East Harbour”) was opened on Friday, 21 June.

This 650,000 square metre expansion of the harbour will consolidate Esbjerg’s position as the leading North Sea port for the wind turbine industry and increase its potential to develop and grow other business areas.

The opening ceremony was attended by the Danish Minister for Transport and followed by a harbour festival with fun and entertainment for the entire city of Esbjerg.

This new section of the harbour covers 650,000 square metres, the equivalent of about 100 football pitches. It has taken two years to build and represents an investment of more than DKK 500m.

The Ralated Article:  Mumbai to Host “Dredging in India” Conference

The mission of the conference is to highlight the key trends and opportunities in the dredging sector. The conference will focus on strategies and solutions to meet the future dredging requirements and address the key challenges. It will also showcase some of the noteworthy dredging projects.

The demand for dredging in India continues to remain strong, driven not only by the dredging requirement at ports, but also those of inland waterways, oil and gas, etc.

The Twelfth Plan targets reflect this growing demand. The dredging requirements of Indian ports are assessed at over 1,100 million cubic metres with plans to Increase draught levels at major ports to at least 14 metres. Major ports alone are targeting an investment of over Rs 88 billion in dredging during the plan period. Slurry pump and Gravel pump will plan an important roles in dredging.

There have been several positive developments In the past year. New guidelines for granting security clearance to bidders have been released. New types of contracts and funding sources are being explored. The industry profile has changed with a number of foreign players entering the sector. Also, public-private partnerships for dredging projects are being planned.

However, the actual achievement in dredging has not kept pace with demand growth. In the Eleventh Plan, only 50 per cent of the dredging target was met and draught levels continue to be low. 

This is because the dredging capacity is inadequate to meet the demand. The Dredging Corporation of India is operating over the optimal level of capacity utilisation. Both domestic and foreign private players are plugging the gap.

Moreover, there are lingering issues such as slow project implementation, lack of standardised documents, delays in policy formulation, absence of a level playing field, financial constraints, and delays in procuring environmental and security clearances.

That said, the opportunities in the next few years are substantial, driven by a focus on the development of ports, inland waterways, etc. The sector offers significant potential for the introduction of new technologies and equipment.  

Slurry pump and Sand pump will plan an important roles in dredging.

What's the environmental influence of geothermal heat pumps?

A Geothermal Heat Pump can be a pump which makes use of all organic resources to heat and cool a property. The distinction amongst a Geothermal Heat Pump and an actual heater can be a Geothermal Heat Pump draws its supply of heat from the ground, even though an actual heater creates heat from utilizing electricity which may be costly.

Geothermal Heat Pumps may also be identified under the names of; Geoexchange, Earthcoupled, or Water Source Heat Pumps.

How does a Geothermal Heat Pump get the heat from the ground?

The heat pump utilizes a loop of refrigerant sucked by way of a vapor compressed refrigeration cycle moving heat either in or out. The source of heat is actually considerably far more stable and continuing then air based heat which tends to be less controlled. The other benefit is the fact that Geothermal Heat pumps may also be utilised to pump the heat out of the property for instant cooling for the duration of hot climate.

Geothermal heat pumps may also be far more economically friendly and can lessen the effects of pollution, electricity, and global warming.

What would be the diverse types of Geothermal Heat Pumps?

So far several of the diverse forms of geothermal heat pumps in existence are; Ground Exchange, Direct Exchange, closed loop, vertical, horizontal, pond, open loop, and lastly standing column properly.

? Ground Exchange ¡§C This sort of heat pump makes use of the grounds present heat and exchanges it together with the temperatures within your property. In case you program to have a ground sourced heat pump then you may need to have a heat exchanger which sits against either ground or ground water to generate the pump function appropriately.

? Direct Exchange ¡§C As an alternative to employing a circulating refrigerant the direct exchange geothermal heat pump performs by using a SINGLE loop refrigerant in direct thermal speak to together with the ground.

? Closed loop ¡§C The standard technique utilizes two loops on the ground side and one particular loop positioned inside the appliance cabinet which exchanges temperatures together with the loop that's pulling the temperatures from the ground. Closed loop systems have considerably longer and more substantial pipes implemented into the ground for greater accuracy and also have an added loop located in amongst the refrigerant loop along with the water loop, pumping in each loops. Closed loops are available in two diverse varieties themselves one particular becoming the vertical closed loop along with the other would be the horizontal closed loop. The difference amongst the two becoming the vertical closed pump has pipes which run vertical by way of the ground even though the horizontal closed loops have pipes running horizontally by way of the ground.

? Pond ¡§C Pond based heat pumps will not be frequently utilised on account of the must be close to an external supply of water. Pond based heat pumps are far more preferred and encouraged for men and women who desire to use a pump but have undesirable good quality water, or possibly a low heat source at the moment containable by a common heat pump. The Pond based heat pump gets its name from the fact that the loop dragging within the heat is located underneath a sizable physique of water, by way of example a pond.

? Open Loop ¡§C An open loop can be a heat pump which draws in water from an external supply outlets it within the major refrigerant where heat is extracted from the water source along with the water is then returned to the external supply.

? Standing column properly ¡§C A standing column properly heat pump is considerably like an open loop heat pump except it truly is made to pull in water from deep inside a properly and exchange it for heat in the major refrigerant where it truly is then returned back in to the properly even though traveling down it exchanges heat together with the bedrock.

How does a geothermal heat pump operate in significant buildings?A geothermal heat pump performs in all diverse approaches every single make varying determined by its finest function for what it truly is replacing. By way of example a heat pump moves anyplace in amongst 3 and five times more quickly than the heat or electricity in which it consumes it truly is truly outputting far more power than it truly is inputting this causes the efficiency of thermals to exceed anyplace amongst one hundred and 200 percent. Even though your typical electric device will generally never ever exceed 100%. This proving that a geothermal heat pump will constantly exceed the efficiency on the electric device it truly is equivalently made against for any precise constructing or structures size.

What's the environmental influence of geothermal heat pumps?

The influence is usually to be frank quite positive, making much less greenhouse gases, and built to be biodegradable and non toxic inside the external sources. However the negative side is that the refrigerant technique makes use of a variety of refrigerant that's truly a lead to of depleting the ozone layer. This refrigerant is called chlorodiflouromethane, it truly is harmless when utilised appropriately but leaks may cause the ozone layer to deplete. But don?¡¥t be concerned this product has been favored out and is getting replaced using a far more environmentally risk-free product.
