Harnessing plasma technology to transform seed treatment and waste management for a cleaner, greener future.
We envision a world where agriculture and industry work in harmony with the environment. By providing solutions that eliminate the need for chemical treatments and reduce waste, we are making strides toward achieving that goal. Our vision is to create a circular economy where waste becomes a resource, and seeds grow in healthy, chemical-free soil.
Viridhys is expanding its vision to include the valorization of plastical waste. Using advanced plasma technology, Viridhys aims to transform plastical waste by-products from industrial processes into valuable resources. This not only reduces waste but also helps industries minimize their environmental impact, making Viridhys a leader in the circular economy.
Founded by Frédéric Haase, Viridhys began with the simple idea of using plasma technology to solve two of the most pressing challenges in agriculture and waste management: reducing chemical use in seed treatment and transforming plastic waste into energy. Over the years, we have grown from a research-driven startup into a pioneering company that is scaling its innovative solutions globally.

An eco-friendly seed treatment technology that eliminates fungi, bacteria, and pests without using harmful chemicals. Ideal for both organic and conventional farming, Plasmaseed® is a sustainable solution for improving seed health and crop yields.
A plasma pyrolysis technology that turns plastic waste into valuable energy sources such as gas and liquid fuels. This process not only reduces plastic waste but also generates clean, renewable energy without producing harmful emissions.
MCS employs magnetocaloric technology to provide efficient, eco-friendly cooling without refrigerant gases. Using magnetic fields to create temperature changes, this system offers an energy-saving, emission-free alternative to conventional cooling, supporting sustainable practices across industries while enhancing performance and reducing environmental impact.
Viridhys is dedicated to advancing sustainable solutions in agriculture and waste management. Our mission is to reduce environmental impact through innovative, eco-friendly technologies like PlasmaSeed, Pyroplas, and MCS that promote cleaner, greener practices.
Viridhys is headquartered in Saint Aubin, Switzerland, where we develop and test our technologies in our state-of-the-art facility, housed in the former Novartis research center.
Our solutions are designed for a range of industries, including agriculture, waste management, and energy. Whether you’re a farmer, an industrial facility, or a municipality, Viridhys can help reduce waste, improve efficiency, and promote sustainability.
Viridhys specializes in PlasmaSeed for eco-friendly seed treatment, Pyroplas for waste-to-energy conversion, and MCS for energy-efficient cooling solutions. Each technology supports sustainable practices and helps reduce chemical and carbon footprints.
Through PlasmaSeed, our chemical-free seed treatment technology, we help farmers improve germination rates, reduce chemical use, and produce healthier crops—all essential to sustainable farming and organic agriculture.
Viridhys was founded by Frédéric Haase, a multi-entrepreneur with expertise in high-tech recycling and sustainable innovation, driven by a vision for a cleaner, greener future in agriculture and waste management.
