Biosphere – Manual of Good Practices in the Collserola Natural Park

In the following link you can consult the Good Practices Manual for visitors and residents of the Collserola Natural Park. A complete manual that addresses the different situations in which we can find ourselves when interacting with the park. He provides us with a list of recommendations, either for walking or cycling routes so that our presence produces the least possible impact and our relationship with the environment is completely satisfactory.


Installation of solar energy systems (photovoltaics)

At the Inout Hostel we have almost 200 solar panels installed


Wastewater reuse

At Inout Hostel we recognize the importance of using resources responsibly and sustainably. One of the ways we do this is through the treatment and purification of the wastewater we generate in our facilities. Instead of seeing wastewater as waste, we see it as a valuable resource that we can reuse intelligently.


How do we do it? We use an advanced wastewater treatment system that effectively purifies water, removing contaminants and waste. Once the water has been purified, we do not waste it. Instead, we redirect it to our outdoor spaces and gardens for irrigation.

Home automation solutions – Motion sensors in the lighting of all corridors of INOUT Hostel

Energy is a limited resource. Approximately 20% of the world's electricity is used in lighting. A large part is wasted, sometimes, in factories, offices and closed spaces. This has a negative influence on both energy resources and the environment.
At INOUT Hostel we have designed a system aimed at solving these problems by installing motion sensors in the lighting that optimize the switching on and off of the lights.


We have a charging point for electric vehicles

Let´s reduce

INOUT Hostel reduces plastic packaging. It also has a Biomass boiler installed for hot water consumption and local pellet heating. All lights are LEDs. It also has sectorized thermostats installed to control the temperature. To minimize water consumption, INOUT Hostel has installed push buttons in the showers.


We reuse

INOUT Hostel has a commitment to responsible consumption and tries to reuse the furniture and objects that others discard.

We recycle

INOUT Hostel is located in a Natural Park and we are committed to environmental protection and minimizing our impact on the immediate environment.

We declare a state of climate emergency

We have joined Declara Tourism, an initiative that supports organizations, companies and professionals in the tourism sector to declare a climate emergency and take measures to reduce their carbon emissions.
