Chinese Environmental Law For Foreign Invested Enterprises

Chinese foreign investment law requires the issuance of an Environmental Impact Assessment (EIA) in before many types of projects are commenced,particularly construction and renovation projects (this requirement applies to both new and existing enterprises). The EIA is used to evaluate whether proper and effective protective measures have been taken with respect to the project’s potential environmental impact. The trend in China is towards stricter environmental standards and more consistent enforcement.

Since certain Foreign Invested Enterprises may be exempted from the EIA, it would be wise to submit a brief but thorough environment impact self-assessment in the feasibility study report, addressing the following issues:

* Raw materials and chemicals stored or in use * Technical aspects of the production process * Types and discharged volume of pollutants, including sewage, solid wastes and atmospheric emissions * Discharge of liquid waste (sewage), and volume and concentration of key parameters * Measures for prevention and control of environmental impact.

In the event that an Environmental Impact Assessment is nevertheless deemed necessary, its scope will be decided by the Environmental Protection Bureau at the level of government (township, local, provincial, national) that supervises your project, but will likely be more extensive. In general, an Environmental Impact Assessment must cover water pollution (sewage), atmospheric pollution, solid wastes discharge and noise pollution. If, for example, only one type of atmospheric pollutant is assessed likely to pose environmental problems, the scope of the Environmental Impact Assessment may focus only on this type of pollutant. If pollutants must be discharged, a permit will often be required. Failure to obtain an approved EIA and the necessary permits can result in various penalties including the shut-down of your project.

Although the time taken to complete an Environmental Impact Assessment depends on its scope, it usually takes 2-3 months. There is no fixed tariff system for Environmental Impact Assessment reports, but the regulations provide for 5 fee-based components: research, supervised sampling, laboratory experiments, testing, evaluation and reporting.

Cleaning Up – If you are purchasing a site with existing environmental contamination, be aware that the Chinese law usually attributes liability for clean-up to the party that caused the contamination. However, the environmental regulatory regime is rapidly developing, and future regulations may require current Land Use Rights holders or occupants to clean up environmental contamination. Accordingly, due diligence should include a thorough environmental survey before land use rights are acquired.

Cincinnati Schools’ Environmentally Sound Building Featured In National Education Magazine

Cincinnati Schools’ Green Renovation

Cincinnati School’s has in effect a long term $1 billion building project that will help to renovate and rebuild many of its older buildings. One Cincinnati School ‘s elementary school, Pleasant Ridge Elementary School, has been recently featured in District Administration. This national magazine focuses on issues in K-12 education. The article from the August issue discusses the growing concern and interest in green building and environmentally friendly construction. The article states that even though the upfront cost can be more the long term benefits of green construction are quite clear. The construction of Cincinnati Schools’ Pleasant Ridge Elementary School is not only a gain for green construction strategies but it also teaches the students important lessons about the environment and responsibility.

Cincinnati Schools’ Pleasant Ridge Elementary School will be the first LEED School in Cincinnati Schools upon its completion. The LEED Green Building Rating System was devised by the U.S. Green Building Council which has helped Cincinnati Schools write its new building plans and codes. The article refers to the work of Ginny Frazier as one of the major influences on the Pleasant Ridge Elementary School project. A private citizen who lives in the area, Frazier is the head of a local group that advocates environmentally friendly building. She went to the Cincinnati Schools’ authorities and administrators with proposals on how the school in her neighborhood could be rebuilt using green materials and environmentally friendly tactics. Some of the ideas she proposed included according to the article, “geothermal heating so the new building uses the earth’s temperature for cooling and heating, using natural building materials, noxious-free cleaning products and art supplies, as well as natural water filtration systems.”

The article discusses the five key areas that the Cincinnati Schools’ Pleasant Ridge Elementary School project uses innovative techniques or old-fashioned common sense to improve the building design. The Cincinnati Schools’ Pleasant Ridge Elementary School project will improve the lighting of the schools in several ways. The lights will feature sensors that will automatically turn off lights in unoccupied rooms. Currently Cincinnati’s City Hall is using a similar system that has greatly reduced energy costs. The Cincinnati Schools’ Pleasant Ridge Elementary School will also have photovoltaic panels, which convert solar energy into electricity. Saving energy with heating and cooling systems is also a concern. All the new and renovated Cincinnati Schools will have central air systems. The article states that, “Air conditioned classrooms prevent pollution from outside, and in the end, help asthmatic children breathe easier, he says. And moisture from hot, humid days can also cause ceiling pads to buckle or gym floors to sag”

Another area the article talks about is indoor air pollution. Cincinnati Schools’ Pleasant Ridge Elementary School project is using less carpet in the design in order to help reduce pollutants indoors. Plans for reducing the amount of water use in the Cincinnati Schools’ would also be based on sensors that detect movement around sinks and toilets. The article comments on the concerns that the Cincinnati Schools’ Pleasant Ridge Elementary School project has in this area. The main concern is in using faucets that have an automatic shut off system or a push button system.

Computer Recycling – Switch To Environmental Friendly Mode

Computer recycling refers to the practice of salvaging useable components from obsolete electronic devices or safely disposing off electronic devices. It is a practice that each one of us must inculcate because inappropriate handling of discarded computers and other electronic devices can cause environmental hazards.

Studies estimate that over 40 million electronic pieces become obsolete annually. These pieces have constituents such as lead, cadmium, barium, and mercury, which are hazardous to the environment. In a landfill, these materials seep into the ground and then into our food and water supplies. This can cause serious health concerns over a long period.

Obsolete Computers: Environmental Threats Obsolete computers that are simply dumped in the garbage drums are the biggest threat to the environment. The computer monitors have cathode ray tubes containing four to five pounds of lead that contaminates the environment acutely. Besides lead, the computers have many other hazardous elements such as mercury, cadmium, and hexavalent chromium. When inhaled over a long period, these elements cause high blood pressure, liver and nerve disease, blood with poor iron, and even brain damage to the exposed group. This causes great concern, considering several million computers become obsolete annually.

Therefore, we must handle the obsolete electronic devices carefully. Moreover, different Environmental Laws have banned the illegal landfills by the disposals of computers and other electronic equipment. These laws necessitate sending the un-functional computers to a reputable recycler for harmless recycling. The laws also specify the need for regular recycling to avoid such computers from piling up.

There are several methods to deal with old computers. Some of them are as follows:

Give It For Reuse: If your computer is in a decent condition, you can sell it to a company or an individual so that it can be used further, or simply donate it to someone needy.

Trade It In: There are many computer dealers (e.g. HP) who offer trade-in promotions on computers and peripherals.

Auction It: You can sell the computer on eBay or any other auction site. You can also organize a quick garage sale and see if any of your friends or neighbors wants the computer.

Set up a Server: You can continue using the old computer as a server to store and share data.

Salvage Some Parts: You can see which parts of your computers are in good working condition. You can salvage those parts and use them in your new computer.

Go for computer recycling and safe the planet earth!

An Environmental Science Degree: An Investment In The Future

The world is changing faster now than at any time since the last ice-age 10,000 years ago and the major cause of that change is man. To allow the changes to continue unchecked is reckless at the least. Monitoring those changes and being able to convince others that we have to do or not do activities that affect the environment will take well qualified people with the relevant environmental science degree.

It has often been said that the education offered in colleges and universities are a direct response to the job market and the trends therein. If this is so then the future for professionals with an environmental science degree could not be much brighter.

After the industrial and the informational age, we are quickly entering the environmental age, where the environment and its characteristics are of paramount importance.

Never before, as a society, have we paid real attention to the environment and many would argue we still do not pay enough attention. Continuous exploitation of the earths natural resources and constant generation of heat and waste products have caused significant damage to the environment.

We live in an age where knowing, understanding and adapting to the environment is no longer a choice – it is the only way ahead. This age demands qualified professionals, especially those with professional environmental science degrees.

A number of allied degrees find their place alongside conventional environmental science degrees. Big business has, for a long time, been required to comply with safety and industrial security requirements. In industries like biotechnology, due to the nature of the products, there are numerous opportunities for disaster.

Disaster management and hazardous material management are fields of study that are very much in demand by today’s high technology industries. While often these studies are not comprehensive enough to be offered as science degrees by themselves, these courses are more often than not partnered with environmental science degrees as part of a package deal.

For the environmental science degree student, it can be an advantage. While pursuing their main course of study, they can get qualifications in a number of allied fields. This makes them thorough professionals and capable of entering a wide range of industries when they graduate with their environmental science degree.

As a result of the long-standing lobbying activities, the United States is home to some of the worlds largest and best funded environmental groups and many professionals, working for these groups, have environmental science degrees.

Jobs exist with government bodies, lobbying positions with political groups and corporate organizations, research positions with foundations and other research organizations. More opportunities exist in the environmental safety departments of leading oil majors and even faculty positions at colleges offering environmental science degrees. They all offer lucrative positions that professionals with an environmental science degree can hope to secure.

An environmental science degree does not deal with environmental topics alone. Due to the very nature of their work, professionals who acquire an environmental science degree need to be equipped with allied subjects like compliance, law, criminal justice, and public communication.

The courses of study that ultimately lead to a environmental science degree are varied and interesting. Someone with an environmental science degree is likely to be tasked with protecting our environment as a result we need the very best!

If you have a concern about the World we live in or a desire and determination to do something to improve a steadily deteriorating habitat, then an environmental science degree would be an excellent place to start.

Anyone aspiring to be an environmental professional would typically need to go in for a BS Environmental Science Degree before going for an MS or a PhD in Environmental Studies.

Environment science degrees are offered in all major colleges and universities across the United States and the Western World. An environmental science degree can be taken full-time, part-time or by distance learning so whatever your circumstances you can contribute.

Automotive Salvage And Environmental Safety

Environment awareness has increased around the world together with the necessity for better regulations that will allow automotive salvage become a safe environmental occupation. Under law enforcement, automakers should take care of their products from cradle to grave. Carmakers are subjects to great international pressure and urging that all dismantled car pieces, wrecks and carcasses should no longer pile up in waste metal yards, but be reused or recycled.

Is it just metal piling up in salvage yards, which has brought automotive salvage into the spot light? Only partially; as there remains the risk of chemical pollution and infestation due to all the vehicle fluids that pollute the soil, should there be any leakage. Those company owners that deal in car dismantling should follow some general basic environmental security rules when fragmenting cars to pieces.

The best way to minimize spill-over during automotive salvage operations is by evacuating fluids before dismantling and depositing these fluids to safe tanks or containers. Fluids should be immediately removed from all the constituents of the vehicle. If this were not possible, check for leaks, and in case you find any, isolate them and reduce the risk of contamination.

The fluids that result from dismantling automotive salvage should be kept in safe containers or tanks. These should be labeled and inspected on a regular basis in order to prevent alterations or leaks. In case they are deposited outside the salvage yard, they must be equipped with a double protection system from the external environment.

One great advantage that automotive salvage has is that it makes possible the reduction of the production price per component in big vehicle companies that can invest in recycling items or reconditioning them for reuse. Some automakers are also talking about increasing the number of recycling points, where automotive salvage might become the starting point for alternative building materials.

The question that has brought much heated debate is: “To whose expense?” Who pays for automotive salvage that is for dismantling, for reusing, for recycling? The answer to this may be the answer to a whole bunch of environment issues that originate in careless automotive salvage in junkyards.

Managing the automotive salvage yards would dramatically reduce the amount of scrap that fills the land. There are thousands of independent automotive salvage yards owners who need a efficient recycling system as they see the pile growing on their property, as not all of it can be sold or re-used without reconditioning.

Asbestos: A Deadly Environmental & Health Hazard

Asbestos is a term used for some naturally occurring minerals that form long thin fibers and fiber bundles on crystallization. Most commonly found group is the serpentine group that includes Chrysotile (white asbestos). It is also the most frequently mined form of Asbestos. Another very important asbestos group is known as the amphiboles, which includes Crocidolite (blue asbestos) and Amosite (brown asbestos). The asbestos fibers have high tensile strength, and chemical, electrical and heat resistance properties and so are extremely useful as a building/insulation material. Asbestos has been used extensively all over the world.

Asbestos: General Information

Although Asbestos is a hazardous material, it poses a health risk only if the Asbestos fibers become airborne and subsequently inhaled. Therefore, most Asbestos materials pose little health risk unless they are disturbed in a way that allows the fibers to be released into the atmosphere. Inhalation of asbestos fibers can lead to serious diseases such as lung cancer, Mesothelioma (a cancer of the lining of the lungs or lower digestive tract) and asbestosis (a chronic fibrosis of the lungs).

Many industries used Asbestos extensively in the past, exposing their workers to this deadly materials. As a result, many new cases of Asbestos caused ailments are occurring now. However, the fact that Asbestos was also installed in many buildings means that a wider range of people still have the potential to be exposed – particularly building and maintenance workers. For this reason, the latest revision of the Control of Asbestos at Work Regulations introduces (from May 2004) a new responsibility on those responsible for non-domestic premises to manage the asbestos contained in them.

Asbestos Caused Diseases

Mesothelioma is a cancer of the pleural and peritoneal lining. It exclusively related to asbestos exposure. By the time it is diagnosed, it is usually fatal. Mesothelioma has a long latency period (time between exposure and onset of disease) of at least 15 years and sometimes as long as 60 years.

Asbestosis is a scarring of the lung tissue. This scarring impairs the elasticity of the lung and hampers its ability to exchange gases. This leads to inadequate oxygen intake to the blood. Asbestosis restricts breathing leading to decreased lung volume and increased resistance in the airways. It is a slowly progressive disease with a latency period of 15 to 30 years.

Lung Cancer is a malignant tumor of the bronchi covering. The tumor grows through surrounding tissue, invading and often obstructing air passages. Again, the disease has a long latency period of at least 20 years.

The victims of all these asbestos related diseases are eligible to file lawsuits for compensation against the persons and organizations responsible for causing asbestos exposure. They can take the help of mesothelioma and asbestos attorneys to fight their compensation claims.

Bamboo Flooring – A Sensible, Environmentally Friendly Alternative To Hardwood

There are many different flooring materials available today including one of the most beautiful and environmentally friendly, a bamboo floor. No, this isn’t taking round bamboo stalks and lashing them together to make a floor for your home. Bamboo flooring in one of the most durable and unique flooring materials you can get for your home today.

Many hardwood floors feature a nice grain and wood look that is very pretty especially in the various colors and patterns. Bamboo flooring however features a much more subtle graining pattern and because of the way it’s manufactured, features more of a pronounced ring like pattern. So you have a grain that suggests a direction and every so often a uniquely bamboo ring pattern. Bamboo can also be stained and finished just like regular hardwood flooring.

Bamboo is actually a grass like plant that grows quickly and is usually considered an aggressive plant. That is, it tends to grow rapidly, overwhelming many of the other plant life in it’s immediate area. This makes for a very sustainable resources as a full bamboo crop can be harvested in less than 7 years. This is a much better alternative to hardwood trees that can take upwards of over 20 plus years to mature.

Bamboo, traditionally thought of as an Asian but specifically Chinese plant has found a new home in products for the west. As bamboo has gained in popularity, many more people are protecting bamboo forest areas and are much more concerned about conservation. The growth of bamboo use for furniture, blinds, many home decor products, and bamboo flooring has created a robust economic incentive to grow natural products instead of clear cutting to make way for farming.

Bamboo flooring is comparable to hardwood floors in durability, looks, and installation. It has broad appeal and beauty that will not easily go out of style. Due to the interest in bamboo flooring, you can now find it in commercial buildings, hotels, restaurants, offices and many high traffic areas.

Another great benefit of bamboo flooring is price. Due to the rapid growth rate, the cost of fully stained and sealed bamboo floor material can be found for less than half the cost of planked hardwood. Bamboo floor can be installed using any of the usual hardwood flooring installation methods. These include a floating floor where the floor is simply glued together to form a single piece, straight gluing to the old floor material and a basic nailing method.

If you’re looking for a uniquely beautiful flooring material that will provide years of ambiance and warmth to your home, look no farther than a high quality bamboo floor.

Solar Introduce: How Does Solar Power Function?

Basic principles of solar energy.

Solar Power is most likely the cleanest, most practical type of renewable energy obtainable and also it can be used in a number of forms to help power your home. Numerous gardens today use solar lights or solar garden water features. The accessibility as well as wide use of solar energy in gardens shows just how versatile it is as a source of power. The technology and the systems have become smaller, more compact and also better looking compared to when they were first developed and utilized. Early samples of solar energy systems can be observed in California where, in the 1980s, enough solar energy panels were installed to power over 10 million homes.

Just how do photovoltaic tiles function?

Simply put photovoltaic tiles and other types of solar energy function by transforming some of the energy in sunlight into a clean kind of electricity which you can use in our houses. The PV cells consist of a positive along with a negative slice of silicon placed under a thin slice of glass. Since the protons of the sunlight beat down onto the PV cell they knock the neutrons off the silicon. The negatively charged free neutrons tend to be attracted to the silicon but they are trapped by the magnetic field that’s created from the opposing fields. Small wires on the silicon capture these types of neutrons and when linked in a circuit an electric current is formed.

This reaction provides Direct Current electricity though, and it should be passed via an inverter to be transformed in to an Alternating Current used in our homes to power any kind of electric items. A few of the power is lost with this part of the process as the inverter is only close to 95% efficient however it is a a lot higher efficiency than was once available.

The nature of the PV cell means there is minimum maintenance required and there aren’t any moving elements; which means that a typical Photovoltaic cell can last up to 40 years with no work besides an annual clean.

How to use them to power my house?

There are many methods to make use of solar energy around the house and not only for powering. You can use this to heat your hot water, heat your swimming pool or even your own central heating or even if you have lots of roof space and a reasonable quantity of sunlight you may get a grid tie system; a grid tie system indicates that not only can you power your whole house but during those times when you produce an excess of electrical power you are able to sell it back to the grid. An efficiently solar powered house can reasonably produce between 75 and 100% of their own power and because of the grid tie system this implies you may well not need to pay for electrical power ever again.

What You Must Know About Solar Water Heating Systems For Your Home

Solar water heating systems for homes have been around for some time. The increasing cost for energy, and growing concerns for the environment have motivated more and more homeowners to consider installing a solar water heating system. Advances in technology, which make the collectors much more efficient, have resulted in reduced cost of these systems. It also helps that, federal tax credits are available to help with some of the cost, provided your solar hot water system supplies 50% or more of the domestic hot water demand.

Two kinds of solar hot water heating systems are used for homes: open loop systems or closed loop systems. Open loop systems are installed in climates where temperatures stay above freezing and where the water is soft. In an open loop system, the incoming cold water is circulated through the solar collectors, and then stored in the solar hot water storage tank from where it goes to the water heater. In the closed loop system, a heat exchanger isolates the domestic water from the solar collector loop. The fluid running through the loop is usually a freeze-proof glycol solution. Because of the added heat exchanger and a bit more piping, the cost of a closed loop system is higher than that of a comparable open loop system.

Size and number of collectors depend on the type of collector you decide to use, for a given hot water requirement. Flat plate collectors and evacuated tube collectors are the two most frequently used types. Evacuated tube collectors have a higher efficiency than the flat plates, especially in colder or foggy weather and climates. It is generally ok to use flat plate collectors in sunny and warm climates, as long as your water is soft. The more expensive, but also more efficient, evacuated tube collectors are a better option in colder, cloudy or foggy regions.

You will need to keep your domestic water heater, or add one in your new home, even with the solar water heating system. It is a must to have this back-up full-sized water heater to ascertain that you have enoughsufficient hot water, even in the event of numerous days of overcast or snowy weather. A solar hot water storage tank is also installed, in addition to the standard water heater mentioned above. Consider the solar water heating system as a system that PRE-heats the incoming cold water on most days. It will be heated to the required temperature in the regular water heater. With a correctly designed system, enough hot water will be made in the solar collectors on sunny days to not require the regular water heater to be used. When you have several days of overcast weather however, that is when the regular water heater kicks in.

Where are you planning to install the solar collectors? I guesson the roof somewhere. The “somewhere” is critical. You have to make sure that the location you decide on receives enough direct sunlight, all year. Numerous tools are available online to help you determine this. Some of these tools are free. Be aware however, that some of these tools might not include the shading from trees. You can also contact a local solar heating system installer. Many will do a free analysis for you and they will include trees and tall buildings next door.

Now on to the roof itself. Will it need strengthening? How exactly will the collector support system be anchored to the roof? What about the pipe penetrations? What will be required to make sure that the roof is still totally waterproof after the solar system has been installed. Talk to a trusted contractor.

More things to investigate. Is there space in the basement or closet, next to the water heater, for the new solar storage tank, pump and possibly expansion tank (closed system only)? For initial planning purposes, you will need at least 2 1/2 times as much space as you use now for your water heater. More is better, so you will have easy access for maintenance.

Almost done. One more thing. The pipes. Where and how can you run them between the solar storage tank and the solar collectors on the roof? You have to find either two locations that can each accommodate a 1″ pipe with 1″ insulation, or put them next to each other in the same chase. Hint: closets or walls behind toilets, if the first floor powder room is below the second floor bathroom. Avoid having to build pipe enclosures in the living room or dining room. Expensive and not very nice looking, unless you are creative and hide the pipes behind a shelf.

That’s it. You have done a lot of the important up-front work. Hopefully you now know enough to be dangerous, can make educated decisions and ask the right questions about how to plan, design, purchase and install, or have installed, a solar water heating system for your home.

Don’t make the same mistakes others have made before you when they were designing and installing a solar hot water system. Get educated and learn how to plan and prepare for a successful system.

Converting Your Home Into A Solar Home

When it comes to converting your home into a solar home, there are several alternatives, because not all homes have the same problems, the same requirements or the same potential sustainable power sources. Therefore, if you are going to try a total conversion or even get off the grid entirely, you will either need to do some research or call in an expert to make a report for you.

If you call in an expert, try to get an independent one, so that you can work out the costs of satisfying your energy needs yourself. You will have to pay for such a survey, naturally, but you could carry out a survey yourself with a bit of work on your part. In order to create a solar home, you may find the rest of this piece interesting.

There are fundamentally two kinds of solar design: passive and active solar energy. Passive solar energy can be used to provide heating, cooling and natural light for your home. Active solar energy is used for powering home appliances, tools and lighting. It is the perfect blend of these two types of solar energy that you will attempt to accomplish, if you are trying to convert your home into a solar home.

You can use passive solar energy techniques in many ways, although they are more easily built in during the actual construction phase of a new home. The largest area of glass should face south or be within 30 degrees of due south. This will catch the maximum amount of heat. This heat can then be distributed around the house by stone floors and stone walls.

The central heating ducting and furnace fan can be used to assist, if necessary. If the house becomes too hot in the summer, awnings or even solar panels could be dropped down in order to put the windows in shadow. When thinking of passive solar energy, you should try to think of means of supplying warmth and coolness without using electricity. For instance, a skylight at the top of the stairs will permit the warmest air in the house to escape, since hot air rises. This will result in cooler air to be sucked into the house at lower levels.

The other aspect of a solar house is the creation of electricity by the deployment of solar panels grouped into solar arrays. Solar panels make use of photovoltaic cells to convert light into energy. This energy can then be used to power everyday electrical appliances of all kinds or some or all of it can be stored in batteries for later use. Conversion from AC (alternating current) to DC (direct current) and back again, if needed, is a straightforward affair.

Solar energy can also be used to warm up water for the pool or for the home. The most common type of system uses pipes filled with a type of anti-freeze to collect the sun’s heat and pass it on to tanks of water by means of a heat exchanger.

A solar home uses energy efficiency to minimize the necessity for heating, cooling and electricity. The use of higher grade lagging, more energy efficient windows, kitchen appliances and lighting than those utilized in traditional homes, will save you a lot of money and energy. As you can see, some of these changes, particularly the passive ones are structural, so hard to apply in many homes, but there is always something you can do to reduce your energy bills and gradually convert your home into a solar home.
