About Rinus & Hans B.V.

Rinus & Hans BV is a Dutch company focused on the cultivation and harvesting of duckweed, also referred to as water lentils. It develops fully automatic, continuous growing and harvesting systems designed to produce duckweed efficiently for both food and feed applications.

The company positions itself around high-yield, low-cost production. Its website emphasizes that duckweed grows very quickly, has a high protein content, and can be processed fresh, dried, or ground, depending on the intended use. Rinus & Hans also presents itself as a partner to customers, offering support and training on cultivation, equipment, and further processing.

• Innovation: Rinus & Hans highlights its own developed cultivation and harvesting concept, including patented elements for part of the equipment.
• Circularity: The system is presented as contributing to circular agriculture, including use with digestate fractions and CO2 uptake during growth.
• Versatility: The plant can be used fresh, dried, ground, or processed into extracted ingredients for food, feed, and other applications.

Unique Aspects
