Analysis for Cleanliness
You cannot control that which you do not measure.
In more and more industries, the exact knowledge of particle contamination is gaining in importance. Contamination of materials in dimensions of a few micrometers was mainly of concern for the pharmaceutical and semiconductor industries. However, not only manufacturers of circuit board components, but also traditional car parts suppliers face new demands on particle recognition and contamination source identification.
Cleanliness for the automotive parts manufacturers has become a huge topic in today’s ever challenging continuous improvement world. The need to define, measure and control the levels of particulate contamination on product is the new norm for suppliers and automotive OEM’s.
Cleanliness directly relates to product warranties, reliability, performance and safety issues. It has long been known that a dirty product gives us poor quality and low life expectancy. The dirtier the transmission from new, the less time it will last.
It is crucial now to identify particles and their source so that effective elimination can be achieved. Residual contamination consists of particles that persist on the component’s surface after the final step in manufacturing. Such contaminants are introduced via parts from suppliers or arise during processing. After vehicle assembly, the contaminant particles can cause severe damage, loss of function or reduce the lifetime of the product.
Cleanliness is defined as the contamination level of a component surface. Common measures to quantify the cleanliness are mass of the contaminants as well as number, size of the dirt particles. In general, the customer will specify contamination limits. The supplier then has to maintain these levels and document them regularly by means of contamination analysis.
The analysis of the contamination has to be proven to not affect the result and to be effective in evaluating all the contamination present. Methods of extraction and evaluation are specified in the international standard ISO 16232. Particular attention must be paid to the extraction method to ensure no contributing factors are introduced to the evaluation. There are different methods of counting the resulting extracted particles but by far the most accurate, repeatable and cost effective is automated microscope analysis. The microscope with software can scan the filter membrane; sort the particles by size class and even determine basic material composition (metal, non-metal, fiber). Once the data is gathered a custom report can be generated based on the customer requirements.

Water’s Role in Global Warming
Water’s Role in Global Warming
Last week, we introduced you to the Resource Matrix, which is everywhere, it is all around us. It is the world that has been pulled over your eyes to blind you from the truth.
We showed you how economics leads to people maximizing their benefits in “win-lose” propositions: you want diamonds and gold for nothing and they want to give you useless junk for a king’s ransom. And how we’ve been hypnotized in believing what they want is also what we want.
But the scales have been falling from our eyes, we’re beginning to see the truth, and the power has been shifting away from the “I want your goodies for nothing” crowd:
- Do-gooders have increased our awareness and worked to change deals from “win-lose” to “win-win”
- There is no “free lunch:” finite energy resources will run out; actions have consequences, and the consequences of our actions are already visible, rather scary, and quite irreversible; and that the “I want your goodies for nothing” crowd hasn’t been telling the truth
We now realize we’re all in this together: we have greater awareness of our actions and the desire to change, and have ways to change.
Hallelujah and Praise the Collective!
Today, we introduce the resource called water, its parallels with fossil fuels, and its role in global warming.
None of this is to dismiss or diminish the contribution of fossil fuels in global warming. Hey, just like the Special Olympics, if you participate, you get a medal. We just think that gold-medal winner Fossil Fuels has stolen the spotlight, letting silver-medalist Water Use keep us hypnotized in believing that water is a free lunch, and that nature will clear up polluted waters while getting away with breaking the rules.
Water, water, everywhere,
not a drop to drink.
According to our friends at How Stuff Works, who I wrote about sarcastically for their oxymoronic clean coal article in discussing how true public relations stuff really works, gives us this data:
- 98% of the planet’s water is in the oceans. It’s salt water – we can’t drink it or irrigate our crops with it.
- 2% is usable. Of that 2%:
- 80% is locked up in polar ice caps and glaciers
- 18% is underground in aquifers and wells
- 1.8% is in lakes and rivers
- 0.2% is elsewhere: either floating in the air as clouds and water vapor, locked up in plants and animals (and your body), and in foods and beverages.
Okay, so 20% of the usable water (only 0.4% of all water on Earth) is accessible, right?
Well . . . no. Many of the aquifers, wells, lakes, and rivers have been sucked dry like a once-juicy fly carcass in a spider’s web. (The 18% and 1.8% you see above is like the money in the Social Security Fund: there actually is nothing there.)
And many of those water sources that do still have a drop to drink are worse than the ocean’s salt water. Drink salt water and you’ll need to yawn into a bucket. Drink this water and you’ll kick the bucket.
And I know you aren’t asking this burning question:
“So . . . global warming to release fresh water from ice caps and glaciers is a good thing, no?”
Percentage this, percentage that.
Talk my language, will you?
I know I’m pulling the disgusting old government trick: drowning you in an ocean of water statistics.
So let’s make it plain and simple:
You bring in $10,000 a month. You’re also living high on the hog and doing your personal best to outshine every bling-bling Hip Hopster Musical Artist in materially conspicuous consumption:
- $9800 goes to the McMansion mortgage and gold-plated Rolls Royce lease
- $160.00 goes to investments in clothing and accessories
- $0.40 has been lost in the sofa cushions
- $39.60 a month is for everything else: food, phone and electric bills, income taxes, and all the other non-essentials: Don’t spend it all in one place!
Aquifers and wells and lakes and rivers:
Dry or polluted, oh my!
Fred Pearce, author of When the Rivers Run Dry, helps us quickly understand it:
We can all save water in the home. But as laudable as it is to take a shower rather than a bath and turn off the faucet while brushing our teeth, we shouldn’t get hold of the idea that regular domestic water use is what is really emptying the world’s rivers. Manufacturing goods … consumes a certain amount, but that’s not the real story either. It is only when we add in the water needed to grow what we eat and drink that the numbers really begin to soar. (emphasis mine.) (Fred Pearce, When the Rivers Run Dry, Boston: Beacon Press, 2006. p 3)
Here are a few numbers he gives:
- to grow a pound of rice: 250 to 650 gallons of water
- to grow a pound of wheat: 130 gallons
- to produce a quart of milk: 500 to 1000 gallons
- to produce a pound of cheese: 650 gallons
- to produce a 1/4 pound of burger: 3000 gallons
He kindly puts water use into perspective in annual terms:
- 1 ton (265 gallons) for drinking
- 50 to 100 tons (13,250 to 26,500 gallons) around the house
- 1500 to 2000 tons (397,500 to 530,000 gallons) for food and clothing

How Many Gallons to Produce One Pound of Beef?
Lies, damned lies, and statistics
US Beef industry’s Cattlemen’s Association: 441 gallons
Fred Pearce: 12,000 gallons
Water Footprint Network: 1854 gallons (calculations: 15500 litres of water per kg; 4079 gallons per kg; 1854 gallons per pound)
In an industrial beef production system, it takes an average three years before the animal is slaughtered to produce about 200 kg of boneless beef.
The animal consumes nearly 1300 kg of grains (wheat, oats, barley, corn, dry peas, soybean meal and other small grains), 7200 kg of roughages (pasture, dry hay, silage and other roughages), 24 cubic meter of water for drinking and 7 cubic meter of water for servicing.
This means that to produce one kilogram of boneless beef, we use about 6.5 kg of grain, 36 kg of roughages, and 155 litres of water (only for drinking and servicing).
Producing the volume of feed requires about 15300 litres of water on average.
—————————————–
Where does all that water come from?
From virtually everywhere
If it comes from imported goods (Thai rice or Egyptian cotton), the water comes from those countries.
When the water is collected from rivers or pumped from underground, as it is in much of the world, it’s:
- increasingly expensive
- increasingly likely to deprive someone of water (nothing to drink)
- increasingly likely to empty rivers and underground water reserves
And when the rivers are running low, as they are more frequently, there is less water to grow anything at all.
The water used in growing and producing goods around the world is known as “virtual water” and the trade of these goods is known as “virtual water transfers.”
And who’s the biggest water exporting Mouseketeer of them all? The United States.
When you drink coffee from Central America, you are influencing the hydrology of the region, virtually taking a share of the Costa Rican rains. The same is true within a national and regional boundaries. The Colorado River is drained so Californians can eat their Big Macs and have friends over for a Sunday afternoon barbecue.
In the same way that your use of fossil fuel is measured as a “carbon footprint,” your water use, actual and through virtual water transfer, is measured as a “water footprint.”
How big is my water footprint?
I’ll show you mine if you show me yours
Arjen Y. Hoekstra, professor at the University of Twente, the Netherlands, introduced the water-footprint concept in 2002. It “shows water use related to consumption within a nation, while the traditional indicator shows water use in relation to production within a nation.” (Hoekstra and Chapagain, Globalization of Water, Malden: Blackwell Publishing, 2008, p. 3)
With Hoekstra and Chapagain’s water footprint calculator (waterfootprint.org), you select your country, input food, domestic water use, and industrial goods consumption, press a button, and you get your:
- total water footprint for the year
- bar charts for the three components
- bar charts for individual food categories
For example, you’re in the US, eat only 1 pound of cereal a week (.4545 kg) and have a low-fat, low-sugar diet, use a low-flow showerhead, use a no-flush eco-toilet, and never run the tap while brushing your teeth. Two extremes:
- You’re the hippiest of the hip: making $10,000 a year: Your water footprint: 245 cubic meters (65,170 gallons)
- You’re the hippiest of the Yuppies: making $120,000: Your water footprint: 2979 cubic meters (792,414 gallons). Difference due to your income’s effect on industrial production.
Three notes on the calculations, because Professor Hoekstra is European and lives in the social welfare country that started birthing hippies in Amsterdam decades before they showed up in the US at Woodstock:
- You input kilograms for food:
- 1 kilogram = 2.2 pounds = 35.2 ounces
- 1 ounce = 0.028 kilograms. 1 pound = 0.454545 kilograms
- Your water footprint is in cubic meters per year:
- 1 cubic meter = 35.3 cubic feet = 266 gallons
- The higher your income, the greater your water footprint, even if you don’t personally consume anything: you’re a capitalist pig supporting the Establishment Regime, I guess
So how is Cinnamon’s capitalist water footprint? Answer: 650 cubic meters (172,900 gallons)
I showed you mine. Now you show me yours:
Get the naked truth: Calculate your waterfootprint now:
Water’s running out:
I get the fossil fuel analogy so far.
And what about climate change?
We return to Fred Pearce’s book to find an example, of which he has oceans:
China’s Yellow River: The fifth longest in the world, it begins high in the mountains of eastern Tibet and journeys more than 3000 miles. Almost half a billion people depend on it for drinking and crop irrigation, and it’s made China the world’s largest wheat producer and second largest corn producer. Yet more than half of the lakes it feeds have disappeared over the last 20 years, and a third of pastures have turned to desert. This desertification generates huge dust storms that choke lungs in Beijing, close schools in Koreas, dust cars in Japan, and rain dust on mountains across the Pacific and Western Canada.
State irrigation projects along the Yellow River soak up the majority of its water – the total official allocations are greater than the actual flow.
The resulting drought could be an early warning sign of global warming.
Much of the declines in moisture reaching rivers is in line with prediction of climate researchers. So how does this global warming happen?
Higher air temperatures from desertification increase evaporation from oceans and intensify the water cycle. This increases atmospheric water vapor – 8 to 10% more than today. This increases global rainfall, but the rain is being redistributed: middle latitudes (read: the US) are becoming drier. Higher temperatures increase evaporation on land, meaning soil dries out faster, meaning less rainfall is reaching rivers.
The higher temperatures melt glaciers and snowpacks. At first, this leads to unpredecented floods. After the glaciers disappear, meltwaters that feed rivers disappear. The combined decreasing rainfall and increasing evaporation will lower moisture by 40% in the southern and western states.
The Sierra Nevada snowpack could diminish by 70 to 80 percent over the next 50 years. And some of the world’s most productive agricultural regions could dry up.
Global climate is becoming more extreme: the dry areas become drier, and the wet areas become wetter. And more areas are becoming dry deserts. Loss of habitat and agricultural lands. It’s a vicious cycle.
So what can you do?
Navigating through the Resource Matrix
As Fred Pearce points out, your drinking and bathing account for 0.05% of your total water consumption. Your food and clothing weigh in at 95.00%, although I find his 12,000 gallons needed to produce a pound of burger rather wild.
As Professor Arjen Y. Joekstra shows with his Water Footprint Calculator, your consumption of meats accounts for a lot, as does your guilt by association of being in an industrialized country.
The obvious solution: eat fewer e-coli burgers from your neighborhood Salt and Fat Slop Bucket restaurant.
The wiser solution: like your choices in energy use, become more aware of the resources needed to produce anything and the consequences. Such as luxurious cotton grown in the Egyptian desert.

How an illiterate, lice-infested, foul-mouthed
peasant on some other side of the globe affects you
We continue going with the flow of water, when we show the parallel between the current hot Oil Wars and in the future cold Water Wars.
And all of this is for one purpose:

Green Tip – Buy Used
A lot goes into making new products; energy, fuel, non organic materials and more. If we buy more items used, we will use less of the things that contribute to hurting God’s planet. Plus, we are being good stewards by making the most of everything we buy and use!
Some things we can buy used:
* movies. what’s the difference, really. used is cheaper, the same and better for the planet.
* music. see above.
* clothes. thrift stores can save you tons of money as well.
* books. buy them used or go to the library.
* cars. how used is up to you.
* furniture and appliances. garage sales and eBay are great places to start.
* homes. old houses are cool anyway.
* household items. there are many items you can pick up at a local good will or garage sale that are just as nice as going to the store and buying new.
* electronics. just be careful and always try it our before you buy.
* bikes. have you ever seen the price tag for a new bike recently. yikes! buy used and ride the bike as often as you can instead of driving. Double green for your trouble! lol.
* video games and systems. places like game stop are great. you can buy used, beat the game and then trade it in for another used game. too cool, right?
* toys. obviously clean and good condition are key here. if you look you can find some goodies. i have found a lot of cute items that my kids love.
As you can see, there are many ways we can help contribute to being good stewards of God’s planet. Including, buying used and spending our money wisely!

Green Computing
Green Computing
Green and Clean Computing
Little thought may be given to the energy consumption of computers, but as more and more computers are purchased each year, it is not just the number of computers that forces increased energy consumption but the way in which computers are being used that adds to the building energy burden. Research has shown that most computer desktops are not being used a great deal of the time they are running and are left on for long periods of time. As with other forms of energy consumption, electricity is wasted when it is not being used and this burns fossil fuels that emit carbon dioxide into the air and cause smog, acid rain and other detrimental environmental side effects.
The typical desktop computer consists of a system unit which houses the central processing unit (CPU), a monitor and a printer. The CPU may require 100 watts of electrical power; the monitor, which may be 15 to 17 inches, may require another 50-100 watts; a laser printer can use as much as 100 watts or more while ink printers use as little as 12 watts while printing. The cost for operating a 200 watt system all day and night, everyday, would be $125 annually, while the cost of operation for normal business hours of 40 hours per week would range around $30 annually. Considering the tremendous benefits derived from using computers, this figure may not appear extensive, but when multiplied by the many computers used on a daily basis in this country, the total grows phenomenally.
There are many ways to reduce personal computer energy consumption. Computers, printers and monitors can be turned off when not in use. Many years ago, it was considered harmful to the computer if it were turned on and off periodically during the course of a day. However, the internal circuitry of personal computers is designed to be protected from power damages that might result from on and off switching. Doing so will not substantially affect the computer’s useful life.
The use of screen savers wastes energy and should not be used. They go back to the days when, if not used, images would be ingrained on screens if they remained on too long, but updates in technology have long made the use of screen savers unnecessary.
The United States Environmental Protection Agency has also developed technology for computers and monitors that can be programmed to automatically power down to a lower power state when not in use. This “sleep mode” can reduce energy consumption by 60% to 70% and these “Energy Star” computers serve to gain efficiency without any loss in computing performance.
Green computing extends beyond the personal computer to the use of related devices and materials. For example, paper waste can be reduced by printing as little as possible and only when necessary, recycling waster paper, using electronic mail instead of faxing to eliminate the need to produce a hard copy, and trying to print on both sides of the page when possible. In addition, printer and toner cartridges can be recycled. Although this is a practice that has been discouraged in the past by printer and toner cartridge manufacturers, such recycled cartridges save resources and reduce pollution and solid waste. Disposing of electronics as well can be done through recycling agencies to reduce waste and provide for recycling of functional equipment.
Finally, green computing also means not buying new equipment unless there is a real need for it. Close investigations can be made regarding upgrading hardware or software before purchasing a new computer. However, if the determination is made that a new computer system should be purchased, there are “Energy Star” computers, monitors and printers on the market. In addition, ink jet printers use 80% to 90% less energy than laser printers and soon, even “Green Computers” will reach the marketplace for sale.

Homemade Biodiesel Kits Are Used to Make Biodiesel Fuel by First Timers
Homemade Biodiesel Kits Are Used to Make Biodiesel Fuel by First Timers
The cost of fuel has gone up again that people are thinking of alternative ways to save up on other things just so they can still continue to make use of their vehicles. Actually, there is a better way by which we can save up on fuel without having to let go of other necessities or luxuries that we have in our life. Sometimes we need all this to keep us going. When you take away one or two, you may take away your only source of happiness. So think twice before cutting off hobbies or things that you are already accustomed to.
One thing by which we can save gas is if we make it ourselves. It is possible since homemade biodiesel kits are available for consumers to buy them. There are instructions online and there are even step-by-step videos on how to make biodiesel fuel. These are especially useful for people who prefer to see it than reading about it. The great thing about seeing how it is made is you can actually see the equipments that are being used. So you can always pattern your equipment with what is being shown.
Since you will be doing it yourself, there are a couple of things you have to watch out for. You have to watch out for methanol and lye because it is dangerous. Aside from that, since you will be making use of heat and vegetable oils, fire is always a possibility. First time makers of biodiesel fuel should be extra careful when proceeding and like any other endeavor it takes practice to perfect it.

LEED Schools In Houston Get More Than an E For Effort
LEED Schools In Houston Get More Than an E For Effort
We send our children to school every day and ask them to learn. They are, after all, the future of our world; and so we ask them to learn about right and wrong, learn about the world, and learn how to take care of each other. But do we want them to learn how to take care of the world, too?
That is what LEED Green Building schools in Houston and around the nation are doing. They are teaching the children, through example, what it means truly to earn an A for awareness of the environment’s needs. They stand for the future of America as a benchmark of creation care.
LEED Green Building schools are K-12 schools that are tailor-made to produce an environment safe and healthy for children, comfortable for teachers, cost-effective for the taxpayers, and easy on the environment. By addressing the uniqueness of school spaces and children’s health issues, LEED for Schools provides a unique, comprehensive tool for schools that wish to build green with measurable results. The rating system addresses issues such as classroom acoustics, daylight and views, mold prevention, and environmental site assessment.
In addition, Green schools cost less to operate, freeing up resources to truly improve students’ education. Their carefully planned acoustics and abundant daylight make it easier and more comfortable for students to learn. Their clean indoor air cuts down sick days and gives our children a head start for a healthy, prosperous future. And their innovative design provides a wealth of hands-on learning opportunities.
No longer must they learn through books about environmental safety and/or green projects around the world. Instead, they can learn hands-on at school – through observation and through practice.
Houston has taken the lead around the nation in building green schools. The Houston chapter is dedicated to showing school district leaders how the LEED FOR SCHOOLS process can benefit them. Other leading organizations in the area are also committed. Earlier this year, the Houston-Galveston Area Council joined with the Houston chapter to produce a year-long symposia to educate the public and educators about the facts and costs for LEED FOR SCHOOLS.
They ideally will have all their schools “Go Green” over the course of the next 10 years.
Other cities are following their lead. Salt Lake City, Grand Rapids and Seattle are all among the top cities with at least three green schools. And more are being built monthly. Both students and parents, teachers and administrators see the need and the benefits for green schools, and are lobbying for all school to change their ways.
For students and teachers, green schools mean reduced incidence of asthma, decreased absenteeism, improved academic performance and increased teacher satisfaction. For parents, green schools offer the confidence that comes with knowing their children spend their days in an environment that is both healthy and conducive to learning.
Green Schools get more than an E for effort. They are the bright and healthy future for our children.

How Can Technology Help the Environment?
How Can Technology Help the Environment?
How can technology help improve the environment? Are we promoting a more singular existence, where individualism is the force that is driving us along? We are now living in a world that is in an accelerated mode of change and innovation. Is this rate of change detrimental to our existence? Think about this for a moment. On the one hand we have improvements in all areas of our lives some are greater than others. On the other hand we are looking at the effects of the harmful destruction of our planet earth.
The first computers started to emerge around the 1940’s, now we have computer processors in a lot of the electronic equipment we use every day. We even have computers that can fit in your hand that have more power than the first computers.The first Television and television transmission appeared in 1925 and now we are watching gigantic flat screens, some as big as buildings and others screens as small as wrist watches. In the past 80 years the medical field has also grown in leaps and bounds in the areas of IVF, genetic research, cloning, stem cell research, along with the progress in the prevention, cure and management of various diseases. Other fields such as astronomy, environmental science, weapons/warfare and engineering have also had their fair share of extraordinary development achievements.
Looking at the issues of Global warming and human environment interaction we are currently facing within our natural environment. Should we really be in a race to ruin the land where we live? We cannot keep up with the current technology, just look at all the equipment you have taken to the recycle tip in just the last 12-24 months. Consider how many Televisions, Videos, DVD players, Computers, Laptops, Hi-fi’s and Home entertainment systems you have changed or bought recently, the list is endless. When an improvement is made to a product it can sometimes make the original product obsolete. Satellite Navigation equipment a new and easily available product for everyone. Even if you only use it once a year it is believed to be a must have product. Mobile phones is another product every man and his dog has one these days. How often do you change your mobile phone for the latest model? Can you ever imagine being without a mobile phone? How did we ever cope without them? The raw materials used to make a phone cannot be recycled easily.
I believe as we get to understand one part(s) of our lives we seem to lose sight of others parts that are equally as important. What can be done to slow down the rate of change or how do we as a nation become more aware of the effects of the rate of change has on our environment.
If we could not have a new television or other new product until the old one had been recycled properly we would help the environment tremendously. Today if we implemented this many products or versions of products would be missed because of the speed at which technology changes. Like the latest flat screen with super clear picture quality. It seem that every other week we get the next new and improved product. Just look at washing power or washing up liquid advertisements.
Just some food for thought more to come soon.

Homemade Biodiesel Kits Are Used by First Timers to Make Biodiesel Fuel
Homemade Biodiesel Kits Are Used by First Timers to Make Biodiesel Fuel
The cost of fuel has gone up again that people are thinking of alternative ways to save up on other things just so they can still continue to make use of their vehicles. Actually, there is a better way by which we can save up on fuel without having to let go of other necessities or luxuries that we have in our life. Sometimes we need all this to keep us going. When you take away one or two, you may take away your only source of happiness. So think twice before cutting off hobbies or things that you are already accustomed to.
One thing by which we can save gas is if we make it ourselves. It is possible since homemade biodiesel kits are available for consumers to buy them. There are instructions online and there are even step-by-step videos on how to make biodiesel fuel. These are especially useful for people who prefer to see it than reading about it. The great thing about seeing how it is made is you can actually see the equipments that are being used. So you can always pattern your equipment with what is being shown.
Since you will be doing it yourself, there are a couple of things you have to watch out for. You have to watch out for methanol and lye because it is dangerous. Aside from that, since you will be making use of heat and vegetable oils, fire is always a possibility. First time makers of biodiesel fuel should be extra careful when proceeding and like any other endeavor it takes practice to perfect it.

Benefits For Municipal Waste Management with Plasma Gasification
Benefits For Municipal Waste Management with Plasma Gasification
Plasma Gasification Plant (PGP) projects are being developed by at least five gas plasma technology companies, and there are real benefits to be obtained from this technology for the destruction of Municipal Solid Waste (MSW).
There is some debate still whether the process has been demonstrated to be a vaible technology which can be reliably operated by our waste management companies at reasonable cost and in compliance with all emissions regulations. However, the consensus seems to be largely in acceptance now that the technology is largely proven and inherently cleaner than incineration.
Although, gasification is used as a power generating technology, and gas plasma plants do provide a power feed-in to the local power grid, it should be realised by all that the purpose of selecting plasma gasification is currently that of achieving maximum waste mass destruction. The intent of the PGP is primarily to provide an efficent and clean method of dispoing of large quantities of residual MSW. Plasma gasification, although it does produce energy from waste is not primarliy an Energy from Waste (EfW) or Waste to Energy technology. There are other better proven, more efficient, and potentially always also cheaper ways to produce Energy from Waste, such as incineration.
PGPs suffer a high sacrificial load from the use of power at the electrodes to generate the plasma, and energy is also expended before the MSW reaches the plasma zone in the gasifier in chopping up and ensuring that the particle size of the waste is quite small. For this reason they do expend a large proportion of the power generated just in maintaining their own internal power demand.
However, as a waste destruction method producing an inert residue without creating at the same time high levels of toxic gaseous emissions the gas plasma process excels according to reports made to date. It has every reason to be cleaner as well because the reactions which take place in the plasma state take place so quickly and completely that the toxic organic chemicals produced in other combustion processes simply don’t get a change to be produced.
For a waste management process PGP therefore holds a very good prospect of adoption, as it is a process which is very efficient at diverting waste away from landfill, and thus scores highly among local authority waste disposal engineers who are constantly seeking to comply with regulations to reduce the amount of organic waste sent to landfill.
The PGP process however, also holds another merit and that is that it is being viewed more favourably by the public than incineration, and one main reason for that would be its clean emissions record when compared with incinerators historically.
Throughout Europe the requirement for BMW to be reduced by ever larger percentages necessitates the use of new technology to achieve this high rate of waste diversion, even after high recycling has also been achieved.
Look out for a plasma gasification plant appearing in a district near you soon, and look favourably upon it!
Steve has built a great web site where there are a lot more facts about gasification. This is a hot subject indeed for this technology which has become an essential read for all those who appreciate renewable energy issues and are interested in taking action to reduce the impact of climate change.Article Source: http://EzineArticles.com/?expert=Steve_D_Evans
