Admit it, everyday your car emissions are contributing to pollution. If you want to reduce pollution and at the same time save money, you need to make use of hydrogen fuel cell technology; find out more by reading this article.

Hydrogen fuel cell technology is not new. It started more or less eighty years ago but since it is quite expensive, scientists and researchers don’t find it a good alternative fuel source. Aside from the hydrogen technology, other technologies have surfaced years ago such as the use of vegetable oil and sugar cane to run a car. However, these technologies did not achieve great success because of the hefty price, climate restrictions, and other issues regarding safety on the road. In short, these technologies were unstable.

Hydrogen fuel cell technology is different. In fact, there are now converted hydrogen cars roaming the streets of US, Europe, and Canada. This improved technology is now more stable. Have you tried surfing the internet? The hydrogen fuel cell kits are widely available online and anyone can get it as long as they want to take advantage of the hydrogen technology.

Experts did not find vegetable oil and sugar cane as viable options. Can hydrogen technology offer something different? If you want proof, the technology is proof in itself since it is science reality. With hydrogen technology, you will still need gasoline aside from the HHO generator and conversion tool.

The conversion tool will need electricity from the car battery and this will be used to conduct the process of electrolysis. Through the process, hydrogen will be extracted from water and in turn provide the car with added power. Obviously, at this point in time, hydrogen technology can’t replace the use of diesel or gasoline. Well, who knows what might happen in the future.

By using this hydrogen fuel cell technology, you can reduce your fuel consumption to a great extent and save lots of money. Now, why did scientists and researchers find this technology viable? The reason is that hydrogen technology is much more affordable now. In fact, car companies will soon offer the public with affordable hydrogen powered vehicles.

Conversion projects are easy to build and are quite affordable. If you’re interested with the hydrogen technology, surf the net now. Check out the available resources that are in store for you. You will surely get tremendous savings by simply investing on the fuel cell kits online.

Even if you buy the built fuel cells, the cost is still nothing compared to the savings that you will get in return. Well, if you want changes, you definitely have to spend some money. This is a very good investment because you’re not only helping yourself but you’re also helping the world.

Find guides online to help you go through with your conversion project. Perhaps you have a friend or a relative who converted their car already. Ask help from them so that the task is immediately finished. If everyone in the world consider the use of hydrogen fuel cell technology, life will improve.

Governments and private companies aim to control waste by offering facilities to households and businesses to dispose of it, one of the main methods used are the provision of skip bins. Skip bins can be hired to collect a variety of waste including food, plastics, metal, furniture, timber and construction, garden and electronic waste. The kind of skip bin required will depend on the type of materials you are planning on disposing of. For example, green waste skip bins are used for anything from tree clippings to grass and hardfill skip bins for substances like concrete, soil, rubble and tiles. Hazardous chemicals and contaminated waste can’t be put into skip bins due to the dangers involved and so for these materials it is necessary to call the local council and they will advise on how to dispose of them, hazardous substances include acids, solvents, cyanide waste materials, paints and oils. There are also bulk bins and skip bin hire solutions for the collection of refuse from businesses such as building and construction sites, large size developments and industrial companies. As well as skip bins, amenities are provided to safely dispose of and destroy private documents such as quarantine stock, computer hardcopy, tapes and microfiche and out of date products. Electronic waste is also recycled these days and includes components from disused computers and other IT equipment. Collection and treatment services exist for clinical and medical waste from businesses and industries such as laboratories, surgeries, veterinaries, dental surgeries, food processing plants and hospitals.

The skip hire industry and resource recovery facilities are particularly essential for the future of the environment as they create an awareness of how everyone can help in increasing the amount of waste recycled and thus reducing landfill. Nations all over the world are joining in the attempt to find ways of recycling waste, from using complicated methods to change the calorific content present in waste into electricity or sorting through landfills to remove recyclable materials and reduce the amount of waste that needs to be disposed of. Waste management is an ongoing problem for society, a problem that will never go away, but if managed effectively, can be controlled. ]]> http://beran-env.com/waste-management-and-skip-bins.html/feed 0 http://beran-env.com/grid-tie-renewable-energy-setup.html http://beran-env.com/grid-tie-renewable-energy-setup.html#comments Sat, 17 Oct 2009 07:38:16 +0000 tony http://beran-env.com/?p=80 A common route to take when you decide to switch over to renewable energy is a “Grid-Tie” setup. What this means is your house is tied in with your renewable energy system and tied in to the power grid. The reason this is such a popular route to take is that it allows you to move to renewable energy as you can afford it.

The beauty of a grid-tie system is that it can be configured two ways. The first way is to set up your system with solar panels and wind generators and hook them up to a battery bank. This battery bank is then hooked up to an inverter and powers some of the appliances in your home. This system costs more and is harder to install for several reasons. Firstly, you need to do some re-wiring of your home to integrate you renewable energy system. This requires a licensed electrician and can be a time consuming process. Secondly, you have to buy a battery bank to store the electricity that you generate.

The second setup which is more cost effective and easier in the long run is to simply wire your system directly into the power grid. What this means is that the electricity you produce is being fed through your meter. It’s really cool to watch it spin backwards. There are some things that you should know about this setup though. You will have to check local laws to see whether this type of system is allowed, and you will have to check with your energy company to see whether they will allow you to run this type of system. Lastly, you will need a licensed electrician to do the setup. This way has several advantages though. You don’t need to initially spend a huge amount of money to get up and running, and expanding simply means hooking another solar panel up. You also don’t have to do any re-wiring to your house.

As time goes on you can add solar panels faster because your electricity bill has gone down, and after it reaches $0 you can start buying batteries for the storage system.

For those of us who can’t afford to make the switch to off grid living all at once this is the way to go. It allows you to build your system one piece at a time as you can afford it. It may take you 2-5 years to get running completely on renewable energy, but it is definitely worth it.

In fact, Green buildings are designed to meet certain objectives such as protecting occupant health; improving employee productivity; using energy, water, and other resources more efficiently; and reducing the overall impact to the environment. These buildings with good overall environmental quality can reduce the rate of respiratory diseases, allergy, asthma, sick building symptoms, and enhance worker performance. The green building construction technique include following elements:-

Elements of Green Building Construction Technique

1. Proper Ventilation

Green Buildings provide adequate ventilation to all habitable rooms including bath rooms, kitchens with high-efficiency in-duct filtration system to allow proper drainage of air-conditioning coils to control humidity including heating and cooling systems which ensure indoor air quality.

2. Prevention of indoor microbial contamination

Under this technology, construction and finishing materials are selected with zero or low emissions to improve indoor air quality. Many building materials and cleaning / maintenance products emit toxic gases, such as volatile organic compounds (VOC) and formaldehyde gases which result in a detrimental impact on occupants’ health and productivity. Such products are not to be used in building construction and their finishing.

3. Utilization of recycled material for minimizing the cost of building

Demolition and reconstruction of old buildings is a continuous phenomenon. Population and demand for buildings are increasing day by day whereas our resources are depleting in the same proportion. Building construction activities consume one-sixth of the world’s fresh water withdrawals, one-fourth of its wood harvest, and two-fifths of its material and energy flow. About 22 percent waste material (bricks, concrete, wood, steel, metals, steel pipes, plastic pipes, electric wires, sanitary material etc.) of demolished buildings can be reused or recycled thus prolonging our supply of natural resources and minimizing construction cost. In green buildings, about 25 % recycled material is used.

4. Installation of glass panels

Instead of wood window glass panels are installed in green buildings to allow flow of natural light inside the building during day time.

5. Installation of Rainwater Harvesting System

The green buildings are well equipped with rainwater harvesting system to preserve depleting water resource.

6. Maximizing the use of renewable natural resources

In order to maximize the use of renewable natural resources in green buildings, the energy efficient equipments such as Compact Fluorescent Lights (CFL) and Solar Water Heating Systems etc. based on non conventional energy resources are installed.

7. Minimizing The Use of depleting resources

Since, forest cover is depleting day by day in the world, therefore, use of fresh wood is minimized in green buildings. Wherever, use of wood is considered necessary, in such buildings, the wood of fast growing trees is only used so that utilization of such material may not effect the ecological balance of the earth.

8. Minimizing energy use in green buildings

The green buildings are fixed with energy censors to minimize the use of power within the building. When there is no person within a room, the lights would automatically go off.

9. Water conservation and efficiency measures in green buildings

In green buildings, water is used in most efficient way. The gray water from bath rooms is again recycled to flush toilets.

10. Proper disposal of garbage

The garbage of green buildings is properly handled, placed and disposed off as per Building Bye Laws of respective Civic Bodies by segregating it into biodegradable and non-biodegradable wastes.

11. Maintenance of greenery

In green buildings, the open areas are well landscaped with maintenance of maximum greenery for building healthy environment.

The driving force behind this is to lower our negative impact on the environment and, at the same time, make the buildings we live and work in safer and healthier for us.

According to the United States Green Building Council (USGBC) statistics,`buildings are responsible for all of the following:

39% of US carbon dioxide (CO2) emissions

70% of US electricity consumption

15 trillion gallons of water consumption

Even though there is still some controversy over the effect of greenhouse gases on the environment, the last two statistics are very important for those of us living in urban areas experiencing continuous growth, especially the American Southwest. With our population expansion, aging water and electrical infrastructure, and shrinking landfills, designing and constructing green and sustainable buildings makes practical sense from a utilitarian perspective.

In fact, USGBC data shows that green buildings use 36% less energy, require fewer raw materials, and divert less waste to our landfills. Furthermore, the “increased” cost of green building is only one or two percent more expensive than a conventional building. This minute difference exemplifies the tangible and long-term benefits of sustainable design, primarily due to the fact that green buildings conserve water and electricity. Thus, while they are more expensive to build, green structures will save money by conserving more energy over time.

Another push towards the green build movement is by local governments. More and more municipalities are adopting the USGBC LEED® (Leadership in Energy and Environmental Design) guidelines for new and renovated buildings. In 2006, at the USGBC Greenbuild expo, the Mayor of Denver challenged other major cities to see who can have the most LEED® certified green buildings. They are accomplishing this by offering tax breaks to private corporations and mandating sustainable construction for city-financed projects.

This has led to a dramatic increase in the number of sustainable projects built by LEED® Certified general contractors. However, this growth has not come without challenges. Currently, the following issues are restricting the number of green projects being built:

Increased demand for green products has lead to long lead times

New and unspecified materials are labeled “green” products which are not necessarily certified Building officials are struggling with a steep learning curve on how to evaluate these new products and sustainable building techniques. Despite these difficulties, the USGBC, sustainability advocates, and green building construction management firms are meeting to overcome these challenges.

The LEED® process is constantly under review and continues to adopt the latest codes and products. This includes Standard 189, a new minimum standard for green building. The USGBC is currently developing LEED® 3.0 and working with national code writers to include new products and techniques.

The American Institute of Architects (AIA) has even rolled out a new initiative called “Sustainability 2030,” which at its roots, is looking to design all buildings by the year 2030 as carbon neutral. The USGBC has even initiated the Green Advantage Builders Certification for contractors to certify their knowledge in green building techniques.

So what does green building mean at the end of the day? It’s simple yet profound: Do the right thing for you, the environment, and the next generation. While most companies are concerned with their bottom line, they ought to embrace the idea that energy and water conservation, green building, and the use of “green materials” in construction stands to increase their savings over time while positioning them as a leader in environmental stewardship.

According to the USGBC, we spend 90% of our time indoors. Due to this fact, scientists have identified an increase in allergies, asthma, absenteeism from school, and even work. There have been numerous studies done on post occupancy productivity levels, which have increased within “green” built facilities. Not only does green adaptation result in less sick days taken, but also shows an increase in productivity, job satisfaction, and in the case of schools, better grades.

So, as we positively affect the environment around us with sustainable green construction, we eventually create better health for ourselves. ]]> http://beran-env.com/trends-in-green-building-and-sustainable-construction.html/feed 0 http://beran-env.com/renewable-energy-resources-versus-fossil-fuels.html http://beran-env.com/renewable-energy-resources-versus-fossil-fuels.html#comments Sun, 27 Sep 2009 08:52:07 +0000 tony http://beran-env.com/?p=76 In modern western world the demand for energy has increased dramatically in the past century and it will grow even further and harder in the near future than ever before. The need for energy rises with upcoming markets that also need more energy. Energy is needed for cars, buses, and other means of transportation, but also to run our appliances and provides us light. Energy is also important for our safety. At night or in the dark a lot can be stolen without proper lightning. Energy is therefore needed for our development and safety.

The way we use energy today comes from knowledge that has it’s foundations in the past century and before. Great men like Newton and Philips have set the path for us today to make proper use of energy. The sources which we use for our energy demand are known as non-renewable energy resources. These sources will be discussed here in the article.

Definition of Non-Renewable Energy Resources

The name really explains it very well. Non-renewable energy resources are natural resources that cannot be recycled or re-grown. These natural resources are fossil fuels like coal, petroleum, and natural gas. It also includes mined resources such as the elements used in the production of electricity (uranium and plutonium, for instance). These resources replenish itself in a quicker rate.

Fossil fuels are very versatile. One of their functions is to generate electricity. In order to generate electricity, fossil fuels are burned through the process of combustion. The energy produced from the combustion process is used to power a turbine. The turbine is responsible for the conversion of energy produced from combusted fossil fuels into electricity.

Coal

Coal is one the most used fossil fuels. It is consider too be the most important energy source to produce electricity. The U.S. produces 50% of its energy supply through the combustion of coal. The coal itself is a brownish-black sedimentary rock which contains carbon and other assorted elements. It is extracted from the ground through underground mining or open-pit mining.

Natural Gas

Natural gas is also used to produce electricity. The electricity is produced through steam turbines and gas turbines. Because the gas contains methane the combustion emits less harmful gasses that have a negative effect on global warming. Thus natural gasses are better for the environment compared to petroleum and coal.

There is also another use for it and that is as fuel for cars. It is much cheaper that gasoline and produces less harmful gasses. The disadvantage of running your car on natural gas is that you need more fuel compared to gasoline and the car needs more maintenance. In countries like Argentina, Brazil, Pakistan, Italy, The Netherlands and India it is used as a fuel for cars.

Crude oil

This fuel is the most talk about for the past year(s). The prices for crude oil have gone through the roof and will be rising even more. The demand is increasing while there is less crude oil available. The term black gold is now more applicable than ever before.

The oil itself is very think in consistency and has a dark brown or greenish colour characteristic. It is a complex mixture of different hydrocarbons.

Crude oil or petroleum has various uses. It can be used as fuel or cars and different industrial machines. It is also used as a raw material for products like plastics, solvents, fertilizers and pesticides.

Although the need for crude oil is high and the demand is rising the available crude oil is decreasing. That leaves us no other option than to look for alternatives.

Non-renewable energy plays a very important role in our daily lives. Non-renewable energy will be needed today and in the future. Because this energy source cannot be recycled or re-grown the reserves are limited. The consequences of the shortages of fossil fuels are experienced today and tomorrow. We will need to use these fossil fuels wisely and will need to shift our focus to other renewable energy source. These are the sources that we need to focus on today and years to come.

Waste Management is required for three reasons. One, you can’t be having waste lying around in any area as it will make the area look awful and the waste will raise a stink. Two, if waste is unattended to, it will attract pests and termites and the chances of a disease spreading will increase. Three, Man has realized that, if he allows waste to pile up or even burned, such an act would be disastrous for our environment. It is a mans duty to control waste and recycle it back into use by recovering resources from it.

History Of Waste Management

Once upon a time, when the density of population was low, the exploitation of the world’s natural resources was minimal and manageable. Plus, there was not much of industrialization and the wastes generated by humans were mostly biodegradable and thus their impact on the environment, minimal. This coupled with the fact that not much waste was generated, man did not feel the necessity to manage it.

Time flew, population grew and before humans knew it, the industrial revolution set in (18th Century). People from rural areas migrated to cities and industrial towns en masse. Human consumption began to get concentrated and waste began multiplying. The proliferation of waste led to many diseases such as bubonic plague, cholera and typhoid, which led to suffering and death.

From this event on, the industrialized nations realized the importance of waste management.

Recovering Resources From Waste

As the world population increases and waste grows in volume, the world’s scientists and planners have evolved technologies to recover resources from waste, which can be used again. For example, the developed nations have sophisticated facilities that convert the calorific content present in waste into electricity. In developing nations, manual laborers sift through the waste and extract recyclable material from it, thereby reducing the volume of waste that needs to be disposed.

Recycling Waste

The term recycling is universally associated with waste management. When we say recycle, we mean that our everyday waste will be collected, processed and then reused in another form. For example, products made out of paper, aluminum, plastic are collected and converted back into paper, aluminum and plastic respectively. Recycling of waste items made up of one material is an easy task.

Electronic waste is sent to developing nations where recycling plants extract gold and copper from the e-waste. Used automobiles are scrapped and their metal is sold to scrap lots, which then sell the metal back to factories for re-conversion. And so on.

Waste Management Techniques

Nations employ many techniques to deal with their waste. Here is a brief roundup of these techniques:

1. Landfill: This is the most traditional way of managing waste, by dumping it in a landfill. Countries such as Australia that have vast expanses of land, normally dispose their waste in abandoned quarries or mines. A landfill is an inexpensive way to get rid of waste. However, care should be taken to ensure that only waste that does not harm the environment is dumped in landfills. Populous countries or small countries, such as Japan, have to resort to other means to manage their waste.

2. Incineration: Incineration is the disposal of waste by burning it. However, incineration is not an effective tool for waste management as the burning of waste consumes resources and energy, destroys the recyclable material present in the waste and emits many harmful pollutants.

3. Composting: Composting is a technique in which organic waste materials (food, plants, paper) are decomposed and then recycled as compost for use in agriculture and landscaping applications.

4. Mechanical Biological treatment: In this technique, a variety of waste (plastic, paper, glass, etc.) are fed in bulk into the waste treatment plant. The MBT process extracts the recyclable content in the waste and converts it to calorific fuel that can be used by cement/power plants.

5. Pyrolysis and Gasification: These are thermal techniques, using these, waste is treated at high temperatures and at a very high pressure. In Pyrolysis, the waste material is converted to solid or liquid. The solid material can be further refined into a carbon form while the liquid extract can be used as energy-giving oil. In gasification, the waste material is converted into a synthetic gas, which can be burned to produce more energy.

In conclusion, waste management has become part of our survival strategy. If we have to live, we will produce waste. If we do not treat waste, it will choke us. Waste is a problem, waste Management is the solution. ]]> http://beran-env.com/waste-management-for-a-modern-world.html/feed 0 http://beran-env.com/clean-and-green-living-leads-to-healthy-living.html http://beran-env.com/clean-and-green-living-leads-to-healthy-living.html#comments Fri, 18 Sep 2009 08:02:17 +0000 tony http://beran-env.com/?p=32 The living green can be a difficult thing when we are not completely sure how to go about doing it. Some may assume that the living green is a complicated or difficult process. Previously, it was tough to live green. In addition, keeping energy costs down and replaced inefficient equipment, only little person can do. These can be obtained from the large budget of the solar home. Today, solar panels are not a luxury, because the price is not high. And fortunately there is a lot less than other methods can help in the home’s ability to go green. Some of these other methods are worth exploring.

For example, did you know that there are organic cleaning agents that can replace many of the traditional chemical detergents that are commonly available on the market? These detergents are made with natural products that do not deliver the problematic fumes that can make the interior of a home unsafe. And, most damaging to the environment is the release of these chemicals into the environment when they are washed down the drain. The impact of such weak disposal on the environment can be significantly enormous. Through using biodegradable and natural detergents, this negative impact will be completely eliminated. These natural detergents are also no where near as expensive as some assume which makes them quite accessible to a variety of budgets.

Sometimes, taking a few basic simple steps is all that is needed to enhance the ability of a home to go green. Purchasing incandescent light bulbs is another simple method for reducing your home’s proverbial carbon footprint. Such light bulbs use far less electricity than the traditional light bulb and last much longer. In addition to helping the environment, these light bulbs also help keep you home budget in check!

Then, there is the most common means of making sure a home is green: recycling. Recycling is significantly important to preserving the environment because it is able to reduce a number of problems associated with environmental depletion. Paper, as most are well aware, derives from trees. When you recycle something as basic as a newspaper, you are eliminating the need to need to cut down trees for future paper production. Recycling plastics is something many people will take part in although they may not be completely sure how this improves the environment. The reason it is so helpful is because plastic derives from petroleum which requires oil to product. By recycling plastic, you are reducing the need to deplete oil reserves. This helps keep the environment clean and keeps the price of a barrel of oil low.

Yes, the first step may be taken to ensure it is appropriate to the green house is not near as tough as some of the assumptions place. To take some basic steps to achieve the necessary results will certainly put your home into a house in line with environmental requirements. Yes, if you want to help the environment, you can do something fairly easy to achieve in a way.

Engineers from the African nation Kenya have devised ingenious tractor trailer systems to serve as waste management equipment.

The invention called the “Ndume Little Pick-up” has come about as a consequence of partnership between the UN organization “UN-Habitat,” and two engineering firms from Kenya to execute work on the Lake Victoria Water and Sanitation Initiative.

The Indigenous Waste Management Process

The Ndume Little Pick-up has a flat deck body and a very low loading height. It facilitates waste management as its flat body can carry eight bins of waste at a time, which is lifted on or off the pick-up manually.

The plan is to let the little pick-ups serve six of the seven towns in the region. To accomplish the task several pick-ups would collect bins of waste from businesses and residential areas and transport them to large containers or other trailers to be eventually carried to the disposal site. From where a waste treatment plant may take over.

This seems to be a noteworthy partnership between the public and the private sector. Further, not only is the program innovative but is also self sustaining, here’s how?

When it’s about government funded services in under developed countries, it’s often the finances which stymie the efforts. However this system would be self-financing, in the sense that the revenue generated from the service provided would be fed back into the system. Thus providing enough funds for the upkeep and manning of the vehicles, which would also lead to regularity of the service.

While the rich nations try to cut back on carbon emissions using sophisticated technology, the not so rich countries invent their own ways to save the environment.A medical industry’s overview reveals that most of it is geared towards developing treatments, but I think they should also pay heed to towards creating conditions that prevent disease.

Durability is a key tenet of a good green home plan. A green home plan will strive to use eco-friendly building materials and furnishings and will incorporate leftovers wherever possible. A green home design will make use of materials that are renewable and long lasting. The less often you have to replace materials, then the less material and effort that needs to go into maintaining them, resulting in a diminished cost of upkeep and less frequent replacement. Cork, bamboo and eucalyptus are examples of earth friendly and renewable materials that feature prominently in environmental building designs. Recycled materials should also be used wherever possible. This is relatively easily achieved when it comes to flooring as you can sand and refinish or even paint and stencil what is already there. Recycled glass (vertrazzo) looks attractive and comes in a range of colors. It can be used for both kitchen countertops and as a backsplash.

Efficient energy use is another key component of a green home plan. Using energy efficient appliances is a must and most manufactures these days will label their products with an energy star rating. But the biggest difference we can make is by leveraging that great bundle of natural energy called the sun. A solar power system can deliver most of an average household’s daytime energy needs and any excess energy that is created can be fed back into the electricity grid. Rebates for the installation of solar panels and also their improved efficiency are seeing the cost of installing residential solar power systems come rapidly down. The energy savings we can achieve by installing a solar panel array will be complemented by installing energy saving windows and ensuring that our homes are properly insulated. Both measures are designed to trap heat inside the house during cold weather and reflect heat when it is hot, leading to a reduction in heating and cooling costs respectively.

The third pillar of a good greenhouse plan should be the efficient use of water: something that is particularly pertinent for those living in drier climates. An enormous amount of perfectly good drinking water is wasted each day on activities like clothes washing and flushing toilets. These activities could just as soon be done using grey water (recycled water). Home water treatment systems such as a wet compost system or a sand filtration system will achieve the aim of using water efficiently.
