Mission

Achieving both stable food supply and
reduction of chemical pesticides

We are committed to solving the global challenges of increasing food demand and environmental/health risks from the repeated use of chemical pesticides, aiming for a safe, secure, and sustainable agricultural system.

From Japan to the world, we are dedicated to promoting next-generation, environment-friendly agricultural materials, striving to create a world where everyone can eat delicious food to their heart's content.

Food Demand to Increase by 1.7x by 2050

Driven by global population growth and economic development, world food demand is projected to increase from 3.43 billion tons in 2010 to 5.82 billion tons by 2050. Pesticides play a crucial role in protecting crops from pests and diseases to maximize the production of high-quality produce.

50% Reduction in Chemical Pesticide Risk

If food demand increases by 1.7 times, 1.7 times more chemical pesticides would be needed to ensure stable crop yields. However, the increased environmental burden from their repeated use and the emergence of drug-resistant pathogens are significant issues that agriculture must address.

The EU has a goal of reducing chemical pesticide risk by 50% by 2030, and Japan by 2050. This calls for a transition to sustainable agriculture that balances food security with chemical pesticide reduction.

Cavitation Plasma Technology
Water Vapor Microbubbles & High-Speed Discharge 600,000 times/sec

Cavitation plasma is a new underwater plasma generation method that utilizes cavitation bubbles, achieving over 100 times higher processing efficiency than conventional technologies. By using the depressurization boiling phenomenon called cavitation, high-voltage pulses are applied 600,000 times per second within a water stream containing a large number of water vapor microbubbles, generating plasma with high efficiency. By exposing regular water to this underwater plasma for a certain period, cavitation plasma treated water is created.

Types of Cavitation Plasma Treated Water

Cavitation Plasma Treated Water
Reactive Oxygen Type & Metal Ion Type

Cavitation plasma treated water is 99.9% water, with trace amounts of 0.1% hydrogen peroxide and electrode-derived nanoparticles. Depending on the electrode material, there are two types of treated water: the reactive oxygen (W) type and the metal ion (Ag) type. Especially the metal ion type is suggested by previous research to support a healthy cultivation environment for crops.
