Norddeutsche to expand copper scrap recycling by 2011 - 0 views

Norddeutsche Affinerie AG (NA) said it is expecting at least EUR40 million of synergies each year from the takeover of Cumerio which was completed in March this year. The company said that it will benefit from the transfer of best practice between the two companies while cost savings mainly come from logistics and process optimization. NA also plans to increase production at its Cumerio smelters. The company expects further acquisition opportunities in Europe and in other parts of the world, including Asia. NA plans to expand its operations in southeastern Europe and the Black Sea region to capitalize on its strong economic growth before looking for growth opportunities outside Europe. In Bulgaria, the company currently expands copper cathode production capacity of its Pirdop smelter to 180,000 tonnes per year. -
Norddeutsche Affinerie is to invest €62.5M to increase by 60% its copper scrap recycling capacity in Lünen, Germany by 2011. The investment will double the firm's capacity to process complex copper-bearing scrap such as shreddings, powders and electrical scrap to 140,000t/y, bringing total scrap recycling capacity up to 350,000t/y from 220,000t/y currently. The scrap will be processed into copper cathode. The investment will see the installation of a second smelting furnace, and a waste gas purification plant in Lünen. Norddeutsche's current secondary smelter in Lünen uses a range of scrap, whilst its Hamburg plant uses copper concentrate and a small percentage of high-grade scrap. Electronic scrap availability has increased in Europe as end-of-life regulations have been introduced for its disposal.
A Silver Lining for India's Housing Market - 0 views

But today the scenario is different, with builders getting a mix of mid end and affordable housing into their portfolio. Raminder Grover, CEO-Homebay Residential, Jones Lang LaSalle Meghraj, says the revival in sales has been, conservatively speaking, to the tune of around 25% across the mid-to-high income segments, according to his company's sales records. Rohtas Goel, CMD of Delhi-based Omaxe too says there has been a 30% increase in sales thanks to factors such as a reversal in general economic sentiment after the elections and more options available in affordable housing. Statistics too would appear to bear this out. India's largest real estate developer DLF says it has sold almost 1,500 flats in various cities since April, notably some 400 flats in its mainstay market Gurgaon, 700 in Bangalore, 100 plots in Indore, 200 flats in Hyderabad and 50 in Cochin. Rival Unitech has managed to sell more than 4,000 units in the last two and a half months in the National Capital Region, Chennai and Mumbai. Omaxe has also sold almost 500 apartments in its Omaxe Eternity project in Vrindavan.
Solar industry fights utility's big solar project - 1 views
-
When Southern California Edison unveiled plans to install 250 megawatts' worth of solar panels on warehouse roofs back in March, it was hailed as a ground-breaking move. In one fell swoop, the giant utility would cut the cost of photovoltaic power, expand the solar market and kick-start efforts to transform untold acres of sun-baked commercial roof space into mini-power plants. There's just one problem: the solar industry is fighting the billion-dollar plan. In briefs filed with the California Public Utilities Commission, solar companies, industry trade groups and consumer advocates argue that allowing a utility to own and operate such massive green megawattage will crowd out competitors who can't hope to compete with a project financed by Edison's ratepayers. (In California, shareholders of investor-owned utilities are guaranteed a rate of return for approved projects, while utility customers bear a portion of the costs in the form of higher rates.) The five-year plan "would establish SCE as the monopoly developer of commercial-scale distributed solar in its service territory," wrote Arno Harris, CEO of Recurrent Energy, a San Francisco company that sells solar electricity to commercial customers. "This would irreparably impair the development of a competitive solar industry."

Turbulence in the Markets: How Speculators Are Crippling the Copper Industry - SPIEGEL ... - 0 views

This is, in fact, the crux of the argument: It isn't enough to simply establish clear rules in a trading center. Governments can only successfully combat speculators if they coordinate their efforts worldwide and remove the cloak of secrecy from their commodities transactions. As long as this fails to happen, the price of copper will remain unpredictable and industry will be at the mercy of speculators. Companies will no longer be able to assume that copper will be expensive when it's scarce and cheap when it's available in abundance. Speculation destroys the basic signaling function that prices have in a market economy, says Heiner Flassbeck, chief economist at the United Nations Conference on Trade and Development (UNCTAD). Although a lot of money moves around as a result of price distortions, speculation doesn't create any real value, says Flassbeck. "The only thing that's created is an illusion of value." Making Life Difficult for Everyone In the end, the popular assessment that speculators are the purest of capitalists is by no means correct. In truth, they are the biggest enemies of the market, because they undermine its central mechanism, the efficient balancing of supply and demand. In doing so, they make life difficult for everyone: for industry, which can no longer predict how expensive its raw materials will be; for consumers, who are forced to bear the costs; and, finally, for copper producers, who face more risk when planning ahead. When the executives at CODELCO in Santiago make investment decisions today, it will be another three to five years before the results become visible. That's how long it takes to develop a new mine or expand an existing mine. The company plans to invest about $15 billion by 2015, but its executives have never been so uncertain about whether their predictions are correct. One thing is clear: Production costs will continue to rise. Now that deposits near the surface, which are easier to mine, are becoming depleted, mining companies are forced to dig deeper and deeper pits.
Counterfeit communications cabling infrastructure - 0 views

“CCCA is raising the alarm again and cautioning by citing real-life failures with copper clad aluminum (CCA) communication cables offered by low cost, online suppliers,” comments Frank Peri, CCCA executive director. “These suppliers promote and advertise CMR or CMP cables that bear counterfeit certification marks or have no listing or verification marks from independent third-party testing laboratories. Using the lure of low price, some online suppliers can entice customers unaware of the true nature and quality of their cables. ”
