In all our processes and at all stages of our salt making, we use geothermal energy. Our production process involves a minimum of mechanical intervention and makes use of natural geothermal energy for heating the seawater, evaporating and drying the Nordur Salt flakes.
From the beginning, we have set a high bar in ensuring that our production facility is as environmentally friendly as possible. As far as we know, we are the only flake salt company in the world that uses geothermal energy to fuel our process. Our carbon footprint is virtually nil, something that we are especially proud of.
We start by filtering the seawater before it enters our evaporation tank to ensure the highest quality of the sea salt. In the filtering process only dirt and leftover seaweed is removed and the salt maintains its natural mineral content. We then lead geothermal hot water through the tank via a titanium heat exchanger while we constantly pump fresh seawater into it. Inside the tank, the seawater evaporates and the salinity level increases. When the brine has reached the right salinity level, it is transferred to open pans. It is slowly heated again using geothermal energy allowing the salt crystals to form as pyramids on the surface. The salt pyramids grow upside down and when they have reached a sufficient size they fall to the bottom.
At this stage, the true art form of our salt making begins; the human touch is a vital factor as the salt is hand harvested to precisely ensure the right taste and texture. Once the salt flakes have been raked from the pans, they are dried using geothermal heating. Then, it is on to the packaging stage and the salt flakes are ready to be enjoyed.
