For preparing simple meals, you will enjoy a bright guest kitchen.
Besides, for saving energy and learning, you can experience the hay-box for cooking, or savour a bread baked in the solar cooker, or see how useful it is the cool box for refrigerating...
Also, through our effective separation and recycling of wastes kitchen, in this Eco Hostel you will achieve "Zero Waste" (or nearly): it will depend on you...
WHAT IS A PARABOLIC SUN COOKER?
|The first solar cooker was invented in 1767 by the Swiss Horacio de Saussure.
The parabolic sun cooker is a concave surface which concentrates sunbeams at the bottom of a black pot.
Nowadays, more than 2.000 millions of people are suffering from the effects of firewood crisis.
The firewood deficit is about 1.000 millions of m3 year.
In consequence, tropical forests are in danger
of deforestation. Patagonia woods are under
pressure too, at the time as demand is increasing.
The present world woodfire consumption is unsustainable and is producing tons of CO2 emissions.
Sun cooking combined with the use of haybox is a great alternative for saving energy.
WHAT IS A HAYBOX OR INSULATED COOKER?
When the sun isn't shining and people are cooking with wood, a lot of energy can be saved by using a haybox. After boiling the food for a few minutes, the hot pot is placed inside an insulated box, where it finishes cooking. The retained heat is enough to simmer the food to completion. A haybox does all of the simmering for us, saving not only energy but effort as well. Saving the firewood that wastefully went into simmering the food results in tremendous savings! A haybox also makes cooking much easier. No more dealing with watched pots to guard against boiling over or scorching.
||WHAT IS A SOLAR OVEN 30º- 60º ?
It is an efficient oven. It is a well isolated box,
with a glass cover. It is possible to set it at an
angle of 30 degrees under the winter sun or
60 degrees under
the summer sun.
WHAT IS AN ECO-FRIDGE?
It consumes Zero energy and has been used for centuries in different countries. The eco-fridge is an isolated chamber located in a shady spot where keep food cool.
For saving water, we use composting toilets.
For saving energy we use a solar system for showers.
Besides we reuse greywater for irrigation.
WHAT IS A SOLAR SHOWER?
We have recycled several materials for building two different types of solar showers. The first one is a black painted water tank inside of a well isolated box with glass cover set at certain degrees under the sun.For the other one we have introduced a pipe through plastic bottles and after we have set it in spiral and placed on the roof.
WHAT IS GREYWATER?
Any wash water that has been used in the home, except water from toilets, is called greywater.
Dish, shower, sink, and laundry water comprise 50-80% of residential "waste" water.
Why use greywater?
It's a waste to irrigate with great quantities of drinking water when plants thrive on used water containing small bits of compost. The benefits of greywater recycling include: lower fresh water use, less energy and chemical use, highly effective purification, groundwater recharge, plant growth, reclamation of otherwise wasted nutrients and increased awareness of and sensitivity to natural cycles.
WHAT IS A COMPOSTING TOILET?
We don’t use flush toilets, but composting toilets.
The composting toilet is a system for the treatment of human excrement capable of destroying the microbes that make us sick without wasting or contaminating water. Besides it is able to transform excrement into a nutrient rich and innocuous compost.
WHY DO WE USE COMPOSTING TOILETS?
- 1.- Because they don’t need water:
A flush toilet consumes about 13 litres per use. If everyone in the world had a flush toilet, there would not be water
enough on Earth.
- 2.- Because they don’t pollute water:
If you stop and think, is not a bit stupid to defecate in clean drinking water, is it?
Traditional flush toilets system is based on using water for carrying human excrement .
A 5-people family pollutes more than 150.000 litres/year for carrying 250 kg of excrement and 2.500 litres of urine per year.
- 3.- Because they don’t use energy:
Energy for pumping water is necessary for flush toilets. Then, energy is needed too for sending black waters to a water treatment center. By combining excrement with water, we create a mixture that is difficult to treat and therefore dangerous.
Purifying these waste waters requires expensive treatment, which is only performed on a fraction of the total. And even this treated water is not safe for your health. Heavy metals, pharmaceutical residues, hormones and toxic chemicals may still be in the water that you drink.
- 4.- Because they don’t loose nutrients:
If well treated, urine and excrement are rich elements for soil. One person produces about 450 urine litres and 50 kgs of excrement per year which could be used as fertilizer instead of polluting water.
FLUSH TOILETS versus COMPOSTING TOILETS
The composting toilet system helps to resolve many relevant issues: infectious diseases, environmental destruction, water scarcity and the need to recover nutrients for the soil.
It is comfortable and odourless. If you have not yet had the opportunity to try out a good composting toilet, perhaps you imagine that since they don't use water they must be like pit latrines, which are generally regarded as smelly, dirty, and technologically backwards.
Thanks to the effective treatment process of this system and proper maintenance by its users, your nose will be in for a surprise when it starts sniffing around suspiciously and can't find any unpleasant smells.
Flush toilet system is an attractive system because it moves its unhealthy effects far away from those who are doing the excreting, but at a cost of polluting large quantities of water.
It's also clear that focal points of disease are not avoided, they are simply displaced, generating a very serious problem for those at the other end of the pipes.
Composting toilet system not only reduces the sources of water pollution compared to sewage systems, but by not using water it attacks this problem at the root, respecting the biological equilibrium of the environment.
We don't need to waste this precious liquid in order to treat the excrement of the world's 6 billion people.
In fact, we never should have started doing it and we certainly shouldn't continue to do so.
