How to Build Emergency Shelters (Step by Step)

How to Build Emergency Shelters: In an emergency situation (night falls, bad weather, cold and other adversities) you may need to shelter yourself. The fact is that you are in the middle of the mountain and without a four-star hotel nearby. That’s why you have to know how to improvise a shelter. And it is that you will not always have the tent at hand.

How to Build Emergency Shelters (Step by Step)

All shelters consist of a structure and a cover, which can be natural or artificial. In general, it is more practical and ecological, except in an authentic emergency, to use artificial means. Except for construction time, in a cold emergency a refuge with natural resources is safer: if it is well covered and small, it will keep our heat better; For the rain, however, an artificial shelter is much better, plastic is more impermeable than hundreds of branches.

The fastest and most practical to use as a cover is to carry in the good backpack a plastic of approximately 2×3 meters, with holes in the edges to pass ropes or wires (sold in almost any large area or hardware store). Passing ropes through these holes, we can tie it to trees or shrubs without the need for structure, although tent pegs (winds) come well to fix it to the ground.

Also, a layer of water or thick aluminized blanket can serve as a cover, although it will be a bit small if we are more than one. And without an emergency, if the weather is rainy, a plastic will make life easier even if you have a store. I find it hard to think how it would have been to work with clients in rivers like the Yukon without a 4×6 plastic; not to mention the jungle, where it can rain in a few minutes.

The shape also conditions the construction of shelter : the most operative are shed with one or two slopes since the tippis (Indian tents) or other forms are more complicated to make unless you have material such as a parachute or a candle.

The structure can be made with simple ropes or by a complicated construction of sticks. In general, the most operative thing is to build a kind of tent with sticks. It is easily constructed with two fork-shaped poles (Y) that act as lateral supports, and a pole supported on both forks along the main support of the roof. Behind this main structure, the cover (the plastic) can be raised with two other smaller forks.

And in the case of using a natural cover, you will have to tie or place more sticks to support it (as you can see in the image on the left). Do not forget to secure the plastic to the ground by placing some stones on shelters with natural resources always require a structure, and can be covered with branches, leaves, bundles of grass, moss, grass bricks or combinations of these materials; In general, the denser the structure, the easier it will be to place material on top, and the easier it becomes waterproof. The materials that form the cover are placed from top to bottom, mounting one layer on another as if they were tiles.

Although it is difficult to get the material, all practitioners of outdoor life should be able to raise a shelter with natural means with the least possible ecological impact: thrown sticks, grass or cut cereal leaves, pruning remains (branches with leaves they are quite useful), cut scrub (where it is very abundant) … although almost everything today is illegal. But remember that your life is worth more than an alteration in the environment; A storm can have much more impact and nature recovers. Be careful out there, especially in this case with the Civil Guard: what to do the Indian is increasingly difficult.

Creative Ideas to Reuse or Recycle Aluminum

Remember that in the extreme case, a fallen tree, a dense shrub (not thorny) or a small cave can be emergency shelters that can be improved with relatively little work; getting between dry leaves can save you from dying of hypothermia. Also, parts of your sports equipment (a paragliding sail, a kayak, and even a bike) will be used as building elements in an emergency !!


  • The location is also vital when making a shelter or camping: avoid risk areas such as floods of rivers or streams, falls of stones, areas of dense vegetation or near stagnant waters with possible “inhabitants” at less annoying
  • The temperature is important: the zones oriented between the East and the South will have more sun exposure, and the sun will shine from earlier.
  • In valleys or valleys avoid the bottom: it will be colder, and too high it is easy for the wind to affect your refuge.
  • If you are in an emergency if you can camp in visible areas.

11 Creative Ideas to Reuse or Recycle Aluminum

What is Aluminum?

Recycle aluminum: Aluminum is a non-ferromagnetic metal. In the earth’s crust, it is the 3rd most common element. Aluminum compounds make up 8% of the earth’s crust and are found in most rocks, vegetation, and animals.

Recycle aluminum

In the natural state, it is found in many silicates. Like metal, it is extracted only from bauxite, by transformation first into alumina through the Bayer process and then into metallic aluminum by electrolysis.

It is very useful in materials engineering, due to its low density (2,700 kg / m3) and its high resistance to corrosion. Using suitable alloys, its mechanical strength can be increased. It is a good conductor of electricity and heat, it is easily machined, and it is very cheap. It is the metal that is most used after steel.

The main drawback in its manufacture lies in the high amount of electricity required for its production. This problem is compensated by the low cost of recycling aluminum, its long useful life, and price stability.

The primary aluminum can leave the factory with different shapes and alloys. And from there it goes back to put in other factories to elaborate fuselages of airplane, cars, plates to print newspapers, window frames, products of cosmetic or simple cans of soda.

How To Recycle aluminum

The 75% of the aluminum that has been manufactured for more than 125 years (approximately 700 million tons) is still in use thanks to recycling since aluminum can be recycled infinitely many times without losing its properties. Recycling aluminum is a very profitable business; it is estimated that the Kilo can be around 0.6 Euros.

Once the aluminum reaches the recycling plant, the first step is to separate it from other metals and elements that can contaminate it through various methods. Once all the impurities are eliminated, the aluminum is pressed, packed and sent to cast iron. Later it is moved to specific plants for its return to the manufacturing chain. There, the smelter or refiner turns it into ingots or billets, which will be used to create new products.

With only 5% that is used to extract aluminum from bauxite, aluminum is extracted from all the scrap that is recycled. So, look if the recycling of this material is important, it saves 95% of the energy necessary for its manufacture. Perhaps a simple can seems little, but its value is much greater than the one that marks its price.

Research continues to discover new methods to try to recover most of the aluminum used in the industry. We recently learned that a new method had been developed in Cambridge that can separate aluminum from other components in just two minutes, ideal for the recycling of toothpaste tubes or tetra-brick containers. To do this, they introduce a mixture of carbon particles and plastic-aluminum pieces rolled in the conventional microwave and inject nitrogen to extract the air. Two or three minutes at 600 degrees later (depending on the amount). The mixture has been converted into pure aluminum shavings and hydrocarbons that can be refined to make fuel.

The researchers are now trying to expand the technique commercially. Each year 160,000 tons of laminated aluminum-plastic are produced in the United Kingdom. If recycled, 16,000 tons of aluminum could be recovered. Only the Cambridge plant is already capable of recycling 2,000 tons of waste of this type per year.

Ideas for the recycling of Aluminum

It is estimated that around twenty-five million tons are consumed in the world every year, so there is a lot of raw material. Aluminum gives a lot of play, and especially the cans of soda, here are some examples of what you can do:

Benefits of recycling aluminum

  • The recycling of aluminum cans saves valuable natural resources, energy, time and money. The aluminum cans are unique: Within 60 days, a box is recycled and becomes a new can.
  • Aluminum is a sustainable metal and can be recycled again and again. Today it is cheaper and faster than ever to recycle aluminum efficiently. The aluminum can is 100% recyclable and can be reused indefinitely. The aluminum can is still the most recyclable of all materials.
  • In 2007, 54 billion cans were recycled, energy savings equivalent to 15 million barrels of oil or all US gas consumption in one day.
