The Blue Lagoon ecocycle is an example of unique relationship between nature and technology.

The high-temperature geothermal areas in Iceland are found inside the spreading zone of the two tectonic plates which Iceland straddles, the American and the Eurasian plate, closely associated with the country's active volcanic systems. Cold ingressed fluid, a mixture of sea water and ground water, comes into contact with cooling magmatic intrusions at great depth, is rapidly heated and ascends towards the surface. The temperature of the geothermal fluid exceeds 200°C at a depth of less than 1 km.

Blue Lagoon GeocyclePrecipitation in the Reykjanes peninsula seeps down through the porous lava pile, collects at a certain depth as ground water with flows slowly towards the sea. On the coast, the ground water meets the salty sea.

Hitaveita Suðurnesja drills for the geothermal fluid found in the region. The wells area as deep as 2000 meters and the fluid attains 243°C.

This geothermal fluid is then used to heat freshwater for central heating purposes and to produce electricity. This unusual and ecologically sound power plant, the one of its kind in the world, provides, in a sustainable way about 17.000 people with hot water for central heating. Some 45.000 people get their electricity from the power plant.

The geothermal seawater is piped directly to the Blue Lagoon where people enjoy relaxing in the warm aquamarine lagoon and benefitting from its unique active ingredients: minerals, silica and blue green algae. The lagoon holds six million liters of geothermal seawater, all of which is renewed in 40 hours.

Blue Lagoon skin care products, based on the lagoon's active ingredients, make it possible for you to enjoy a part of this extraordinary ecocycle wherever you are.
