Environmental facilities

In some campsites we will find environmental facilities, such as solar panels, biological wastewater treatment plants or compost toilets. We minimize the environmental impact of camps and create educational contexts, allowing children and young people to have the experience for a few days of viable ecological alternatives: we hope that this will motivate them to seek sustainability in the broader and more complex contexts of today's society.



Composters deal with the organic waste generated during camps (food remains) on the same campsite. They save garbage dumps 40% by weight of garbage, thus helping to lengthen their useful life and avoid problems such as water pollution, unpleasant odors and waste of resources. The resulting compound contains nutrients that can be assimilated to plants, contributes to improving soil and avoids erosion, while also being a key factor in organic farming.

How should we manage it?

  • Turn the stack regularly.
  • If it rains, make sure the lid is lowered.
  • If the stack has low humidity, water it, making it dry but not soapy.


Compost toilets

Compost toilets allow to treat the excreta without using water, taking advantage of natural biological cycles that transform a problematic organic matter (excrements) into compost, a harmless and useful product for plants. They do not use water or any chemical product, and therefore do not waste or contaminate the water.

How should we manage it?

  • After using it, we pour some straw from the drawer.
  • If it smells, we add a lot of staw.
  • If only we have to urinate, better in the forest!


Biological wastewater treatment plants

Biological wastewater treatment plants treat dirty water from taps and showers, returning these waters to the environment in conditions of quality, or re-using them to fill the tanks of the toilets, thus achieving a significant saving of drinking water. At the same time, the wetland ecosystem increases the local biodiversity by providing a water point that is very useful for many animal species, especially during the summer season.

How should we manage it?

  • Preferably, we use natural and biodegradable soaps.
  • Rationalize the use of cleaning products such as detergents, disinfectants, bleach, etc.
  • We do not enter the enclosure nor do we damage the wetland plants.


Solar thermal energy

The solar thermal energy systems allow to obtain hot water for the showers and the sinks of the campsite with facilities thanks to the direct utilization of the solar energy. It is an effective solution to fight against atmospheric pollution and the greenhouse effect, very related to the production and use of conventional energy sources. In addition, the energy transport infrastructures are avoided and simple and reliable equipment installed by local companies is used.

How should we manage it?

The amount of water that can be heated daily is limited. Let's try to use only the amount of hot water needed.


Photovoltaic solar energy

Photovoltaic solar energy systems transform the energy of solar rays that reach the campsite in electric power for lighting and plugs. It produces energy without environmental impact and noise, and also has advantages such as simplicity, modularity and reliability.

How should we manage it?

The energy that can accumulate batteries is limited. We avoid unnecessary energy costs, such as leaving lights in the toilets when they are not used. We also avoid using appliances that consume a lot of energy.



If you are a MEG scout group, in your territorial demarcation you can borrow the entire eco-kit or only the part that interests you. Each eco-kit consists of:

  • 1 solar parabolic kitchen + special pot
  • 1 universal solar charger (for mobiles and others)
  • 1 solar lantern with mechanical traction by hand-crank.

How should we manage it?

Handle the appliances carefully, avoiding blows or exposures to the rain. In the case of solar kitchens, you have to be careful because it is dangerous to place yourself in front: you could burn it! Be cautious and follow the instructions given to you with the eco-kit.
