About the project

What we are going to build here in Hopkinsville is something unique. Here, Cinis Fertilizer will manufacture the world’s most sustainable mineral fertilizer from residual products from advanced engineered battery materials. We will use traditional and proven process technology powered by fossil-free electricity. Our end product, potassium sulfate, will be an important contribution to the green trans­formation of agriculture.

The production method that Cinis Fertilizer will use is known as the Glaserite process and has been around since the 1950s. This method of producing SOP is well proven and the technical risk associated with it is low.

What's going on:

Agreements with key partners signed.

Pre-design initiated.

Cinis Fertilizer is part of the solution to several major sustainability challenges. Our ability to help the agricultural industry in the necessary shift towards a sustainable approach and reduce the industry’s residual products constitutes a large part of the value we will create for customers, shareholders and employees as well as people and ecosystems worldwide.

For Cinis Fertilizer, it is important to have a dialogue with everyone who lives and works in our immediate area. Our ambition is to have ongoing and transparent communication, create local jobs, contribute to the development of business and sustainable economic conditions, which includes taxes and local collaborations.
