Environmental Responsibility & Sustainability

Malama 'Aina - Respect the Land

Nutrex Hawaii’s corporate philosophy is to leave the land and environment in better condition than when we started. All of our microalgae comes from our parent company Cyanotech’s 90-acre farm located on the pristine Kona Coast on Hawaii Island. Our microalgae farm was carved out of land that was once a barren lava flow. Our team is steadfast in its commitment to sustainability and everything we do is to create a cleaner, safer and healthier world.

Water Stewardship

spirulina_ponds Water is essential to our production. We utilize local fresh water from Hawaii Island’s pristine aquifer. To minimize water waste and return essential nutrients back into our growing ponds, the majority of the fresh water we use is recycled and returned to the pond for the next growing cycle.

Sustainable Crop

Spirulina is one of the world’s most environmentally efficient crop. Spirulina produces 20 times more protein per acre than common crops such as beef, corn and even soybeans while using 10 times less water to produce it. And, our efficient patented process converts spirulina from the pond to the bottle in under 30 minutes. pond

Green Operations


The active and very efficient photosynthesis of our microalgae sequesters carbon dioxide and produces oxygen. In fact oxygen is the main bi- product of our microalgae production.

Nutrex Hawaii’s Ocean Chill Drying™ system dries our Spirulina in just three to seven seconds, relies on very cold deep ocean water to provide de-humidification, and uses less than one percent oxygen to preserve the phytonutrients.

Reduced Carbon Footprint

In 2014, we added a 2,280 solar array panel that’s run by Neighborhood Power Company to produce 1,147,000 kilowatt hours of electricity each year. The energy production is sufficient to power our farm’s production during daylight hours, and is projected to reduce our company’s greenhouse gas emissions by 791 metric tons of carbon dioxide per year—that’s equivalent to the annual greenhouse gas emissions of 167 passenger vehicles. solar_panels

Clean Energy

The company utilizes water that is pumped up from 2,000 feet below the surface of the Pacific Ocean to cool its ponds to run its Ocean Chill Drying process that was explained earlier in this chapter. The cold seawater is also as a source of air conditioning for Cyanotech’s offices. By running pipes through its buildings, the company is able to bring in the cold water and efficiently and effectively cool its offices with low energy usage.
