EcoMag is committed to the principals of the ‘circular economy’ and minimising the Company’s overall environmental footprint. The EcoMag process is based on a sustainable resource, and offers direct environmental benefits.
EcoMag’s processes involve extracting about 98% of the magnesium content from an existing waste stream that has been flowing into the sea for over 50 years. The magnesium content of the residual bitterns is less than 0.1%, similar to the level found in sea water. In fact the elemental composition of the EcoMag’s residual bittern flow is substantially closer to that of seawater than the unharvested bitterns in terms of both relative and absolute levels.
Magnesium is the eighth most abundant element in the earth’s crust, and the third most abundant element dissolved in seawater. As such the supply of magnesium from seawater is sustainable and effectively inexhaustible.
Reduced CO2 emissions
EcoMag commissioned a detailed life cycle analysis from the German Aerospace Center comparing CO2 emissions produced by its process with;
- extraction from magnesium chloride (from seawater) – the ‘Aman’ process, and
- extraction from magnesium silicate ore using high temperature processing – the ‘Magnifin’ process.
The analysis confirms that the EcoMag process has lower CO2 emissions than the comparable processes in all scenarios.
Even giving the comparable processes the benefit of CO2 credits, their best case scenarios produced higher emissions than EcoMag’s best case scenarios.
