In an effort to curb solid waste pollution, China banned the import of scrap polysilicon at the beginning of August, an effort supported by its current environmental laws according to its Environmental Protection Ministry. Scrap polysilicon is a low-grade form of silicon not pure enough to use in microchips. However, it can be used as a component of solar wafers, which contain a variety of types of silicon, including up to 30% scrap polysilicon.
The new ban significantly impacts a number of facets of the silicon industry, particularly scrap polysilicon trading and supplying. It will undoubtedly financially threaten Chinese traders as well as smaller solar manufacturers who rely on the prevalence of the cheap material. KK Chan, chief executive of the investment management firm Nature Elements Capital, which specializes in clean energies and technologies, speculated to Reuters that the ban was intended to protect China’s emerging polysilicon industry, which “needs all the help it can get given a supply glut of the material.”
Thursday, the Standing Committee of the National People’s Congress, the inner council of China’s parliament, issued a resolution calling for increased measures and more legislation to fight climate change, saying China will “strive to control greenhouse gas emissions.” Ironically, in their statement they also blatantly rejected the idea of trade protection raised by certain U.S. lawmakers, who have proposed tariffs and other adjustment measures on imported products should China and other big emitters not do more to combat climate change.
Due to the credit crunch and the ensuing worldwide recession, a great deal of funding for emerging energy technologies, including solar power, disappeared. As a result, the demand for solar wafers and solar panels fell drastically, and the price of polysilicon plummeted, dropping over $330 per kilogram since its peak last year. Nonetheless, Chinese production of polysilicon continues to increase, jumping to 86,000 tons by the end of this year.
China currently produces more than 60% of the world’s solar panels. It is one of the most significant users of both high- and low-grade polysilicon worldwide. Since the ban was enforced at the beginning of August, the price of polysilicon in China rose from $67 to $72 per kilogram.

Dear colleagues, the situation today with the rare earth metals has
put manufacturers of electronics and equipment for green energy,
depending on the political leadership of China. Major corporations are
forced to seek alternative suppliers. We consider all the options from
the recovery of previously closed due to non-profitability of plants
to develop new fields.
For example, such plans in Canada and the USA.
Often the content of rare earth metals in the ore of new deposits is
lower than in the industrial waste of metallurgical plants accumulated
in the first half and middle of 20 century in the mills of the former
Soviet Union. Not a perfect technology that existed in the enterprises
are not allowed to extract rare earth metals from ore, and all of them
remained in the waste. In fact, today these wastes – “concentrate”
rare earth metal. The volume of this waste – tens of millions of tons.
It is also important that:
• Wastes are readily available they do not need to extract and transport.
• Plants that would not pay huge fines for environmental damage and
not to fund work on recycling the waste transferred to the ownership
of municipalities. In the municipalities do not have funds for
disposal of these wastes and they are ready to cooperate with the
proposers of decommissioning projects. This allows you to cheap raw
materials for a long time.
Our company’s specialists have developed technology that allows
processing of industrial waste and get rare metals.
We appeal to interested investors – we need venture capital financing
in the amount – $ 2.5 million. Funding necessary to complete work on
the technology and manufacturing pilot plant. Investment we are
attracting the term – 1 6 months.
All those interested in providing financing, please contact by e-mail

GENERAL INFORMATION ABOUT OUR TECHNOLOGY – The technology incorporated
most successful in the world today the decision of the production of
ferrous, nonferrous, rare metals and preparation of nuclear fuel as
pyrometallurgical and hydrometallurgical processing, and
and our radically new method.
On our technology
extracted all the metals that are in the raw material for one cycle in the form
individual metal powders. According to the known technology today –
only one metal or more.
Even the processing of “poor” (% contents of individual metals in raw
materials), but the “rich” (in terms of different metals in the feed)
for this technology – it
to super production.
For example, aluminum production (in
Compared with the conventional technology on the principle of Faraday) in our
technology more attractive than from the salt melt.Aluminum can
receive from any aluminum-containing raw materials (including industrial waste)
with much less energy consumption, multifunctional.
On our technology cleaner production – no
fluoride emissions, degradation products of anode paste and dusting
supply of raw materials in the cell, causing severe disease.
Technology saves electrical energy and resources, all reagents are
regenerated and
reused, virtually no emissions and waste.
In some cases, depending on geological conditions of occurrence
natural resources, possibly underground leaching (extraction)
metals without excavation and rock material breach of integrity
earth’s surface. After many years of accumulated research and
systematized information on reserves of ore, silica,
chemistry of natural and man-made regional raw materials
using data geolkomov Kuzbass, Khakassia, Tuva, a number of
institutions and others from the standpoint of business. Brief essence
technology – selective non-waste production of a comprehensive
kinds of metals from raw materials for one cycle in the form of individual
energy-ultrafine metal crystals with a purity
more than 99,9%. Cost not more than $ 270 per ton, regardless of the form
allocated to the metal. Possible options for the production of filamentous
crystals and so-called “small particles” with special
properties, as well as metals of high purity. Any mineral
metal-containing raw materials consist of metals and nonmetals
(Metalloids), various minerals, soluble and insoluble
various solvents. In our case, all the metals are transferred to
solution in any sequence are extracted, and from the insoluble
Conventional acids silicate residue (sand) in the form of silicon dioxide,
diopside, etc. depending on the feedstock used, after washing
Produced commercial powder. Silicate residue feedstock in the form of commodity
powder at a cost of $ 4 per ton can be used in concrete,
glass, ceramics, production of semiconductor silicon, etc.
Thus, the raw material (ore, industrial waste) can be used
non-waste.
APPLICATION – in metallurgy total and low-temperature powder with

Whiskers and small metal particles “(used for example in aircraft
stealth-type” Stels “) may be used in
Spetstekhnologia. This nanotechnology. Metals in high purity

high-purity silicon metal with a lower cost for
solar panels. For example, it is advantageous to obtain a direct separation of
metals from two commercial concentrates our neighbors Sora
Molybdenum Combine Khakassia, avoiding complex and expensive
production stages in Chelyabinsk – molybdenum, copper, tin,

There are prerequisites for applying the method in studies on
the hydrogen motor fuel.
The technology – the project is recommended as an alternative
highly profitable model of balanced use of mineral
