Solar salt from Australia

In 2016, K+S started the planning process for the construction of a production facility for solar salt in Western Australia. With this, we want to press ahead with our expansion into Asia. We see great growth potential in the region. We assume a possible annual production of 4.5 million tonnes of salt.

Ashburton Salt: Salt from the sea

The project is located about 40km south of Onslow in the north of Western Australia. The coastal region has established itself with several plants for the extraction of sea salt. Solar salt is extracted from seawater - and is therefore from a renewable source. The water is led through open evaporation basins. After several months of solar exposure, the salt crystallizes in an end basin.

We see the potential for long-term, economically successful salt production, from which the population of Western Australia will benefit as well. When completed, the production facility should create about 90 permanent jobs and support local businesses and service providers in the communities of Onslow and Exmouth.

K+S Salt Australia is currently working with BG&E Resources on the final feasibility study for the project. The result should be available towards the end of 2021. We also expect the environmental and mining permits for the project by the end of this year.

Environmental impact

K+S plans Ashburton Salt to be one of the most environmentally friendly solar salt projects in Australia and worldwide. We rely on local and global expertise in order to ensure sustainable environmental compatibility. Environmental scientists and project engineers work hand in hand.

In order to minimize interface with Exmouth Gulf, we have settled it about 40km southwest of Onslow. We create a spatial buffer to the mangrove trees, which are an important part of the local ecosystem, and minimize the impact on algae populations. Residual saltwater to be disposed of is not stored long term. Instead, we are investigating other environmentally sound saline water management methods. Where possible, we will completely avoid dredging on the seabed or reduce it to a minimum.

A comprehensive environmental impact assessment and environmental management system ensure that the impact on the environment in the project area is minimized.
