Gasification Sees a New Dawn and How it Will Benefit Us All
If you search for gasification and terms like “wood stove†on video sharing sites these days you will see demonstrations of wood being burnt in little stoves which seem to something almost miraculous and quite different from our idea of wood as a fuel. These little boilers light rapidly, produce no detectable smoke after the initial lighting and firing, and burn very hot.
So what is the technique which is being used, and how might it help us all in weaning society off fossil fuels?
What you have seen is a method of gasification. It differs from combustion in that it uses just 20% to 30% of the air or oxygen necessary for complete fuel combustion. During gasification, the amount of air supplied to the gasifier is carefully controlled with the effect that only a small part of the fuel burns completely. Trials of this process have illustrated that up to 70% of the energy value of the fue used can be recovered as what is known as synthesis gas, or syngas. This producer gas can also be used for various applications similar to natural gas.
This is a part of the magic, and not one really shown in the YouTube type videos, but it makes this method even more useful. This is due to the fact that syngas can be put to useful work, in both drying the feed fuel prior to gasification and after collection and storage it can be used as a fossil fuel replacement, and renewable energy source. When a gasification plant also includes Combined Heat and Power (CHP) and/or electricity export from the site, the gains are even more impressive.
Gasification in addition promises to be the most efficient long-term solution for capturing carbon while utilizing these valuable feedstocks, and storing the CO2 for very long priods, to reduce or halt global warming.
Gasification of wood and wood-type residues and waste in fixed bed or fluidised bed gasifiers with subsequent burning of the gas for heat production is has become state of the art with designers of thes systems working hard to gain the absolute maximum efficiency out of these systems.
These wood gasifiers which are located primarily in the Scandinavian countries are used almost entirely for space heating heat generation. Gasification of biomass is the renewable fuel system preferred by many, and can be defined as the thermal conversion of solid biomass to gaseous fuel.
Gasification has been around for over a hundred years, but the benefits of biochar are only now being discovered. Furthermore, it is still a wide-open field.
Before electric lighting was available in cities there were street lamps fuelled by gasified coal. It is easy to forget that the process has been reliably used on a commercial scale worldwide for more than 50 years in the refining, fertilizer, and chemical industries, and for more than 35 years in the electric power industry. More than 75 companies involved in the development, licensing, and use of these technologies as well as engineering, construction, equipment manufacturing and production of synthesis gas by gasification from coal, petroleum coke, heavy oils and other hydrocarbons.
Gasification has been proven to be a viable technology for CO2 capture and reducing SOx, NOx, particulate matter, and mercury emissions from coal and petcoke-fired power plants, synthetic fuels production, and chemical facilities.
Plants in this category have been capturing carbon dioxide for several decades in chemical plants in China and the United States. It also has potential contributions to make to both transportation and electrical power energy markets. With ongoing concerns about the price and availability of oil, populous countries like the U.S. gasification has proven to be in high demand and quite successful. However, it can also be used in conjunction with gas engines and gas turbines to obtain a higher conversion efficiency than conventional fossil-fuel electric power generation. Gasification can help meet renewable energy targets, address concerns about global warming, and contribute to meeting global environmental targets.
Steve has built a great web site where there is a lot more information about gasification. This is a hot subject indeed for this technology which has become an essential read for all those in alternative energy and interested in taking action to reduce the impact of climate change.

Water Extraction in DC
There are many beautiful and interesting sights in Washington DC, among them are the White House which has been home to every president of the United States ever since 1800; the Tidal Basin Lake famous for its abundant Japanese cherry trees that blooms in Spring; the Lincoln Memorial and Jefferson Memorial, Washington Monument, etc.
But regardless of the beautiful tourist attractions that one could go to in the State of DC, natural calamities in the form of flooding sometimes happen. And when it does, most household residents in DC do the physical cleanup by themselves without hiring water extraction professionals or experts to deal with the situation. Prior to actual removal of water and cleaning, the starting place of the water which caused the flood should be identified as soon as possible and fixed permanently to prevent it from arising all over again.
Cleaning would usually require having to remove all visible waters first by making use of a wet vacuum pump or a bucket – depending on the volume and availability of equipment. The extraction process must be done immediately or as soon as possible to avoid a higher cost of damage inflicted by the dirty waters and also to thwart of any possibility that the area becomes a source of infectious diseases due to the presence of pathogens.
When all the water has already been extracted, floor coverings should be removed immediately and disposed properly. This includes removing items which came in contact with the flood water that are very porous, because the high absorbency rate of such materials has already contaminated the item in question making it very dirty and highly infectious. No amount of cleaning or fixing could reinstate it in its previously clean state; hence replacements should be made eventually if still needed.
Brushing all affected surfaces with a soapy water solution removes the presence of dirt. Pay particular attention to dirt which is inserted within cracks on walls and floors. Rinse the entire area by using a mop and bucket or a garden hose with a spray gadget.
When the rinsing stage has already been done, disinfecting the entire place is a must to remove remaining germ and fungal spores. Remember that disinfecting does not entirely mean total sanitation but a means of making the area or place habitable again. Never mix chlorine bleach with other cleaning products that contain ammonia as this will produce poisonous gas. Before and during application of any disinfectant, make sure to open all air passage ways and vents to avoid inhaling the vapors of the disinfecting agent upon application.
After having done the disinfection phase, the whole area must be thoroughly dried out, and drying usually takes a couple of days or weeks depending on how big the place is and the weather. The re-occupation of any living space which has been previously flooded must only be done once the area is declared by a professional water extraction expert to be absolutely dry. The dryness is tested by a moisture meter which shows the amount of moisture above and below a given area.

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.

How to NOT Be One of Them – Farmers Are Being Pushed to Increase in Size Or Get Out!
It doesn’t matter what size it is, your farm is an ever increasing asset, even more so if you can provide chemical free, clean food.
Australian conventional food prices are forecast to quadruple in price over the next five years. The reason is Asia. We are in the middle of a global revolution in the way we think, eat and live.
This week I received this news from Craig Sobey who has recently toured China with representatives from five city councils, Austrade and Regional Development Victoria and reports that there is a real opportunity for all to take a significant market share in this period.
Basically, if it is Australian and premium quality there is a ready market. Australia is seen as a source of safe food regardless of whether it is organic or conventional. At this stage price does not appear in the conversation, just consistent supply and traceability. The interest in all products represented included convenience food packages (pre-cooked), meats, dairy, wines etc.
Did you know:
- This co-op now owns China’s fifth biggest supermarket chain with over 500,000 stores.
- There is a farmer’s co-op representative with over five million members?
- 6,000 of them over 30,000 sq metres. The supermarket turned over 18 billion dollars in 2007 with revenues growing by 150 % per annum on average.
- They have offered an entire Australian Pavilion for Aussie produce including organics in their premiere stores in Beijing and Shanghai. Organic Wines were the big attraction.,
- China creates 80,000 millionaires each year.
- There are over 350 million middle class and a niche market of super wealthy Chinese? (Craig told me that French wine is selling as much as $600 a bottle and even one watermelon cost $40!).
However there is real interest in China for organics (which they refer to as Green Food) and particularly food safety/ traceability which is the paramount concern for all serious buyers they met. A new Australian wide network (not for profit) company is being formed for all sections of the organic market. This is so that a pool of members can tackle the export markets together. Its goal is to give you an export premium to help make membership very appealing.
The time is ripe for all growers to stop and think about the future of their farming. What choice will you make? Your future will depend on it. Even if all of Australia’s certified organic farmers, processors etc. were to unite they could not supply the market in China alone and therefore there is untapped potential over the next ten to twenty years to be further developed.
Farming Secrets is a club for farmers who want to farm healthier and more profitably. Farming Secrets reconnects them with the experts through supporting them with one to one help and constant support from experts in order to fast track their farming goals that much quicker.

Can Paper Bags Substitute Plastic Bags?
Bags hold an important place in our lives. They are sometimes referred to as the best personal carriers. They are made of various stuffs like cotton, synthetic, leather and so. But when it comes to general usage like for shopping, the names of two types of bags viz. plastic made and paper made bags come to our intellect. Both are fine, but the question is, which one is the best suited to our requirements. Lets discuss the peculiarities related with the two.
You might be thinking that paper bags are not as durable as those made of plastic. Also, we see that the latter are more commonly used than the former one. But, do you know plastic is a stuff which is really hazardous to the environment. It takes thousands of year to decompose. If burnt, it emits poisonous gases which again pollutes the environment. If buried in the ground, it makes the soil infertile. If thrown in the sea, it pollutes the sea water and proves to be a threat for the life of the sea creatures. One can imagine, how hazardous is plastic to our planet.
This perilous nature of plastic had forced the governments of many cities of the world to put a ban on the use of poly-bags, which are a major source of plastic pollution. Few cities of the world in which these polythene carriers are either completely or partially banned include San Francisco, New York, Texas, Germany, Dhaka, China, Kenya and Ireland to name a few. Even the government of Delhi had issued guidelines against the use of polythene. However, later on the government changed its decision to completely ban the polythene, due to some reasons. Government suggested the manufacturers to set up the recycling units on the basis of “polluter pays principles”. But the government has not completely given up the plan to ban these polythene carriers, it is in the pipeline.
In this context, paper bags are the best option. No doubt, they are unconventional, but they are eco-friendly and easy to recycle. Nowadays, there are various types of paper made bags available in the market. They are not only good looking, but also have ample of space to carry goods and are quite durable. The handmade paper bags available nowadays are designed to suit specific requirements which include carrying gifts, carrying wine, shopping etc. There is a separate bag to serve each purpose. Although, multipurpose bags are also made from paper. They are proving to be the best substitute for plastic or polythene carriers in the modern context.
Now, as we have told you every significant fact related to plastic and paper bags, It’s upon you which one to choose. The hazardous and non-disposable polythene, or the environment friendly and elegant paper bags.

Helping Kids Care For the Earth – Ideas For Earth Day and Beyond
Earth Day is April 22, and while it’s important to get involved on this day, there are things we can do as families that will make a huge impact throughout the year.
It starts with helping our kids to celebrate the world in which we live, and it continues with helping them to love it so much that they want to do everything they can to help protect it. Here are six ideas to help your kids celebrate and care for our earth:
1. Get out and enjoy it. Researchers are now saying that simply getting kids outside in nature may be the most effective way to raise their awareness of environmental issues. Suddenly, these problems that they hear about on the news and in the classroom have a real impact on their daily lives. They see firsthand how a forest or a beach or a tidepool or a meadow is teeming with life, with ecological relationships that are interdependent, delicate and complex.
To encourage your kids to get out there and enjoy the natural world, you may have to purposefully inject some extra excitement in the idea, but just at first. Take your dog (or a friend’s dog) for a walk in the woods. A dog’s love for nature, and subsequent enjoyment of it, is infectious. Create a list of things to find and make your adventure into the outdoors into a scavenger hunt.
If possible, and if your kids are old enough to be by themselves out there, find a safe place for them to play in a natural environment. Allow them to go there to get away, to sit and think or to talk with their friends. Make a point to get the kids out in nature every day. Better yet, go with them.
2. Watch “An Inconvenient Truth” as a family for inspiration. Invite some of your children’s friends over to watch it with their parents and talk about some initiatives that you can each commit to or some larger projects that you can work on as a neighborhood or community.
3. Help your kids learn about endangered animals. Together, look into organizations that help endangered animals and see how you can get involved.
4. Reduce and re-use, then recycle. Lots of kids get excited about recycling. Fewer are into reducing or re-using. Model to your children a healthy pattern of consumption. Talk frequently about the many benefits (which go way beyond environmental) of living a simple life and of being wary of a lifestyle of mass consumerism. As kids spend more time outside and less time at the mall or watching television advertisements, this shift may feel increasingly more natural to them.
5. Teach your kids about potentially harmful chemicals and how they can be everywhere in our world: in the foods we eat, in the supplies we use to clean the house, in our paint, in our cosmetics, in our lawn care products. Turn the search for these things into a game and allow your kids to be detectives, learning about and seeking out these harmful chemicals and then finding natural alternatives.
6. The next time you take the kids to the grocery store, see how you can minimize the amount of packaging that you purchase. We have been known to purposefully not purchase an item because of the manufacturer’s use of wasteful packaging. It won’t take long for the kids to realize that the best item in the store for minimal packaging: raw fruits and vegetables.
In our family, the more we can make these life changes into a game, the more apt the kids are to follow suit. Help your kids to understand how one person really can make a difference (especially when that person is part of a committed family or group) and review often the personal impact that you all have made.

In Houston, LEED Schools 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.

5 Steps to Living a Greener Life
Lots of people talk about trying to live a greener life, with some even going so far as to completely change their lifestyle, but most people aren’t sure how to go green because they don’t know exactly what that means. Sure, most people know the basics that scratch the surface such as reusing, recycling and reducing the amount of waste output for their homes but there many other steps you can take to move towards a cleaner, greener environment.
If you’re wondering how you can make your life greener, here are five different tips that are simple and easy to implement and that don’t cost the you anything. All it takes is a little dedication and after a few months, these five little things will become second-nature to you.
1. The next time you go shopping use cloth bags at the grocery store instead of paper or plastic. These cloth bags can be purchased for as little as a few dollars each and they’re much stronger than paper or plastic bags and will last you through years of use.
These bags help reduce waste since most people throw away the plastic and paper bags. The hardest part of using cloth bags is remembering to take them to the store, but once you get in the habit of using them, it becomes unconscious habit.
2. Replace your standard light bulbs with compact fluorescent bulbs. These bulbs use less energy and last for four to five years, almost 15 times longer than traditional bulbs. While the cost of a compact fluorescent bulb is more than your standard bulb, they easily pay for themselves over time requiring less frequent replacement and reduced energy consumption. In fact, studies show that a CF bulb can actually pay for itself within one to two months. One CF bulb also saves about five pounds of greenhouse gas carbon dioxide a month. Replacing every bulb in your home can have a huge impact on the environment and on your wallet.
3. Use public transportation. By car pooling, taking the bus, or using the subway you can cut down on the amount of gas you use and the amount of exhaust your car emits. While it may be an inconvenience in some ways, it is one of the best ways of helping the environment. Even better, walk or ride your bike to work if possible. This not only saves you money and helps the environment but it also keeps you fit and healthy!
4. Adjust your thermostat by a few degrees. By turning your thermostat down by just two degrees in the winter, you can save over 50 pounds of greenhouse gas carbon dioxide per month while lowering your heating bill. Turning it up a few degrees in the summer can likewise save you money and save the environment.
5. Finally, only wash your clothes or run your dish washer when you have a full load. It wastes water and electricity to wash and dry only a few pieces of clothing. In fact, if you can, try to wash your clothes using the cold water cycle as it uses up to 50% less energy than a warm water one.
By just doing these basics not only you can save some serious money but you can rest assured that you’re doing your part for a cleaner, brighter future. To discover more ideas you can use around your home for living green visit http://www.greentipsforyou.com!

Climate and Biodiversity – Common Policies For Common Good
Concerns about dangerous climate change and large biodiversity loss are visible throughout the world: unprecedented rates of temperature increases and species extinctions are a reality. In 1999 Dr. Peter Raven, president of the International Botanical Congress, published a paper in which he states that “current extinction rate is now approaching 1,000 times the background rate and may climb to 10,000 times the background rate during the next century, if present trends continue. At this rate, one-third to two-thirds of all species of plants, animals, and other organisms would be lost during the second half of the 21st century, a loss that would easily equal those of past extinctions”. He then outlined seven “Points to Slow the Extinction of Plants”, including financial and capacity building instruments to help developing countries protect 80% of the world’s biodiversity they host. As far as climate change is concerned, the responsibility of developed countries is high in providing the most threatened regions in the world with good instruments to cope with this challenge (or at least examples of them to implement autonomously).
Climate change plays a significant role in this human-induced mass extinction because it is increasing the already large biodiversity losses caused by habitat destruction and fragmentation, water and air pollution, introduction of invasive species. Marine ecosystems will be affected by an increase in sea temperature, but also by ocean acidification, because of the higher concentration of dissolved carbon dioxide (carbonic acid): in fact this reduces the shell formation ability in many organisms. Polar (and mountain) ecosystems are particularly vulnerable to climate change, with effects such as thawing permafrost, decreased snow cover, losses from ice sheets and changes in ocean temperatures. Large impacts on Arctic biodiversity are already evident, pictures of polar bears wandering lost on small icebergs being a scary and sad symbol of the era we live in (even former U.S. President Bush, at the end of his mandate, recalled this image to show his fellow citizens he cared about climate change …)
In this rapidly changing environment it is therefore extremely important that conservation plans include adaption measures for ecosystems accordingly to the predicted regional climate patterns (but models need still to be improved a lot at this scale): dynamic approaches are needed to set good options for future ecosystems and landscapes. It will be necessary to facilitate the movement of species to new geographical locations, as they follow the shifting habitats.
The public concern is growing: in Africa last 28 February young people organized a march from impoverished urban areas to the summit of Mount Kilimanjaro to raise awareness on climate change, together with the Kilimanjaro Initiative and the UN’s global UNite to Combat Climate Change campaign. It seems though that the global attention on climate change doesn’t fully consider implications for biodiversity yet: while the negotiations and speeches on climate issues are very popular (and the Nobel Prize was awarded to the entire IPCC together with Al Gore in 2007) the meetings and decisions of the Convention on Biological Diversity (http://www.cbd.int/) don’t raise comparable interest. Is it because the anthropocentrism is (still) the prevailing philosophy and animals and plants are mainly seen by people as beautiful “supporting actors” on the planet we live on? Right when we are losing control of the global situation it is probably time to reflect on our role of dominant species and acknowledge the fundamental contribution of other organisms to our livelihoods, despite many of us live in the so called Technosphere.
Policies to protect the climate avoiding irreversible effects on the ecosystems need to be strongly interconnected with conservation strategies: preserving natural areas while helping them adapt to the changing climate means hopefully to leave better, or not as compromised, ecosystems to future generations. Climate and biodiversity, though ever changing and evolving, are common goods and they need common policies: if we reduce the human Ecological Footprint both the atmosphere and the biosphere will be better off (and our children and grandchildren living in them).

The Ecological Footprint is a measure of human demand on the Earth’s ecosystems. It represents the amount of biologically productive land and sea area needed to regenerate the resources a human population consumes and to absorb and render harmless the corresponding waste. Using this assessment, it is possible to estimate how much of the Earth (or how many planet Earths) it would take to support humanity if everybody lived a given lifestyle. For 2005, humanity’s total ecological footprint was estimated at 1.3 planet Earths – in other words, humanity uses ecological services 1.3 times faster than Earths can renew them.
