Material Recycling

June 10th, 2010

In a layman term, material recycling is a great way to preserve natural resources.  We conserve nature and use our God-given natural resources in an efficient and sustainable way only when we opt to recycle materials used to manufacture after use.  Those scrap metals by the mechanic shop can undergo metal recycling for the manufacturing of a brand new car. Not all materials, especially plastic materials are recyclable. Therefore, you can contribute to saving the planet by buying products made of recyclable materials.

Almost everything in your house can be recycled – the metal, plastic, electronics, glass, textiles, and paper. The process of recycling is pretty easy. First, materials are taken to the collection centres where they are sorted from other wastes such as food; and then cleaned and reprocessed into raw materials for industries. Sometimes we recycle complex products to remove just an element. For example, gold could be gotten from computer parts, and lead from car batteries.

Metal Recycling

Metal recycling is the easiest of all waste management process.  For instance, metals such as steel and iron can be separated from other wastes at a dumpsite magnetically. Such metals are then melted to their liquid form by the use of an electronic arc furnace. Aluminium can also undergo unlimited metal recycling without losing its quality. However, this time, the metal(aluminium) is reduced to pieces and grounded into what is known as bales. Now, you must have heard about aluminium smelter plants, these plants melt the bales to produce liquid-flowing aluminium. One great advantage of metal recycling as oppose to other forms of recycling is that metal recycling can be done again and again without lowering the quality of the metal as suitable raw material for manufacturing purposes. In fact, you can hardly tell the different between a recycled metal and one just gotten from its Ore.

Critics

Several negative things have been said about recycling of materials, especially recycling of metals. Not surprisingly, many of such criticisms have been coming from both the mining industry and the manufacturing industry.  As you know, the mining industry does not want to see a decline in demand or a fall in value of their ores. The manufacturing industry is simply complacent with status quo–business as usual– and do not see metal recycling as a really big deal since it does not significantly improves their profit margins.

Fact and Figure

More than 60% of rubbish that ends up at the dumpsite could be recycled. If you don’t recycle your plastic, it will take more than 500 years to decompose, and before it degrades,contributing to make the environment dirty. In addition, the use of plastic and aluminium for packaging is growing by the year, if we don’t recycle them, then it is a big waste of natural resources.

Recycling reduces wastes by lowering large scale raw material production which in turn reduces energy usage and as such lower greenhouse gas emission. The benefit of metal recycling is far-reaching. When we recycle everyone benefits. There is financial reward to both theword’s economyand private institutions. Above all, we are directly preserving the world’s natural resources for the next generation after us.

Benefits Of Knowing How To Build A Wind Turbine

February 15th, 2010

The recent economic crisis creates a major problem for us who only has meager incomes – incomes that are enough to generate enough budget for food, clothing and shelter. However, there are times when we would want our families to enjoy more than just the basic necessities in life. We also wanted our family members to live a kind of lifestyle that would make them remember their whole lives. Earth has just all the resources present that we could utilize for free. With just the right equipment and devices, we would be able to harness all these free energy that nature provides.

Homemade wind turbines work just like professional turbines. And the great thing about having to create your own windmill is that you could actually save a lot of dollars from your electrical bills. Renewable resource is definitely the answer to our rising economic problems these days. With the abundance of wind power, we just need to create the right medium for harnessing such powerful energy to generate free electricity right at our very homes.

There are many sites online that could teach you how to build a windmill and you have to choose one that would teach you how to save much from the materials being used. In order to get your very own homemade free energy, this article is set to teach you the simple steps on how to build a wind turbine that is just like those made by professionals. First, you need to build the magnet disks followed by the coil disk. Cut the 12 inch hydro disk with a template for mounting the magnets. Then cover with resin and hardener. Once done, build the coil disk. After that, make the bearing assembly and finally construct the blades. When its all made, bolt it all together and you now have your own wind turbine. The magnet is needed to spin the turbine.

There is this other site that I found that teaches how to better make windmills as well. What the author actually did was to compile all the information he gathered from all the other different sites. Afterwhich, he divided it into 5 different major systems: (1) generator-building, (2) blades creation, (3) creation of the mount to keep the turbine turned to the wind, (4) tower creation to reach the wind, and (5) batteries and an electronic control system.

Magnets would work well as generators. There are good brands and models of permanent magnet DC motors that could perform as generators but weren’t designed as such.

In addition, do make sure that you follow safety guidelines
Doing the necessary techniques on how to build a wind turbine will enable you to finally help your family from the financial burden. You will also enjoy your free electricity so much that you would probably make more than one wind turbine. You will then perhaps teach your friends on how to build a windmill so that they too could benefit from free energy.

Investing On A Rammed Earth House

February 10th, 2010

Today, we are stuck in this wild ride of economic ups and downs that we have to be prepared for what’s next. These financial setbacks create even bigger problems when what only meager incomes could afford to purchase. Investing your hard-earned money into proper and more secured assets can afford even the average family a good future. With a house that will not be easily targeted as the termites’ warzone, we could make sure that our children will have a future where they will be happily enjoying.

When you know how to build a rammed earth house, you will also know how to provide for your family. Rammed earth is a building method used by masons in the ancient times and by people who live in areas that are scarce of lumber sources. With rammed earth, the house will be built with materials that are incombustible, very stable, and impenetrable by termites, hardwearing, thermally massive, strong, affordable and quite simple to make. Walls made of rammed earth contain raw materials such as lime, chalk, earth and gravel. Rammed earth is also known in other countries as pisé or pisé de terre (France), taipa (Portugal) or tapia (Spain).

There are abundant resources wherein one can find a good guide on how to build a rammed earth house. Perhaps one could first check some important details before starting to build your own earth dwelling. First, check your soil. You have to have the right kind of earth, which has to be about 50-70% sandy. It must not also contain too much clay or it will shrink and crack. Then, in order to create a homogenous mixture of earth, sieve it through slanted screen of about 1-inch mish of hardware cloth to separate chunks of earth and stones and other materials from your soil. Protect your soil from precipitation by covering it with tarpaulin as even 10% moisture will create a puddle on your soil and it will not compress well. Test your homogenous soil mixture by creating a ball of earth and dropping it. The ball should hold its shape well and scatter and break when you drop it. Finally, when you have all the necessary soil mixture of the right proportions of sand, gravel and clay (sometimes you can add a stabilizer), you and your builders can begin the process of compressing the damp mixture into externally supported frames that would form the earth into sections of your wall.

Creating a foundation of reinforced concrete is one of the modern variations that we could add to our earth homes. Sometimes these footings have added insulation made of a layer of Styrofoam. A good rammed earth house can be a very good investment for you. These dwellings are fireproof and it breathes, thus there is no need for air conditioning or heating devices. It has a very good thermal mass that it can heat up slowly during the day and releases that heat during the night. Also, it provides a good soundproof wall.
