Spirulina Smart Microfarm

By Robert Henrikson, CEO, Smart Microfarms

Welcome to our Smart Microfarm greenhouse just south of San Francisco. The first spirulina farm in Northern California.

Here we grow spirulina, a blue-green algae, year round, in a controlled environment greenhouse.

All naturally grown. No pesticides, no herbicides, no fungicides, non-GMO. 100% vegetarian.

In a small area, fast-growing microalgae, like the superfood spirulina, can produce higher income than growing conventional food, herbs or vegetables.

Spirulina is harvested several times a week. The fresh harvest collects on a microscreen like a creamy yogurt. It can be frozen or dehydrated.

We package and distribute SpiruSource® fresh harvest, fresh frozen, and low temperature dried crunchies and powder.

These healthy superfoods are sold in select local natural food stores. Also in farmers markets, direct-to-consumer, juice bars and online.

Successful small-scale algae cultivation is now practical. With web-based remote sensors and controls developed by Smart Microfarms, remote experts can guide local operators, without the cost of onsite algae scientists.

This breakthrough, combined with scalable, modular growing systems, means algae microfarms – like this – can be installed anywhere in the world.

Smart algae microfarms are a new opportunity for small scale and urban farming in greenhouses with hydroponic and aquaponic growing systems.

Help Reset the Algae Industry

November 1, 2015 — by Robert Henrikson

AIM Lets Reset

Yes, push that red reset button to get the algae industry back on track, by nominating players who are making a real and positive contribution in the world of algae.

Over this past decade, the Algae Industry has been dominated by big money chasing the mirage of commercial algae biofuels. My March 2011 post “Shakeout in Algae Biofuels” described shakeout scenarios about to unfold.

This great biofuel boom and bust raked in billions of dollars in government, corporate and private investment over the past decade, attracting charlatans and collaborators (some who knew better) who sucked up the public bandwidth about algae, burned investors, and discouraged many from funding algae ventures for food, feed and high-value products.

Failed biofuel companies may try to excuse themselves because the price of oil fell. A decade ago, experts with real algae experience could not identify a pathway to make algae biofuel cost competitive with conventional fuel even at higher fuel prices. Where is the path forward today?

Just a few years ago corporate suits were dismissing non-fuel products from algae as “co-products” for “niche” markets. Now they are gone. Their replacements at algae biofuel ventures have desperately tried to pivot to those niche markets and algae co-products like food, feed, nutraceuticals, high value oils and fine chemicals, to show a real income stream for their sponsors.

During this time, we have also learned about the barriers to the massive scale required for biofuel commercialization. This undermines the claim that bigger is better, and renews appreciation of small is beautiful.

Algae industry conferences use to open with a plenary panel of algae CEO “all-stars,” touting their big successes developing biofuels. One-by-one they have dropped away. The largest algae industry organization in the USA engaged in ongoing efforts lobbying for government grants, subsidies and entitlements to maintain the faltering algae biofuel R&D industry.

If 10% of the funding for algae biofuels had been directed into R&D for animal nutrition studies and cost reduction for algae aquaculture and animal feeds and human food, we would already be well along on this path. Growing algae for feed and food will have a far greater impact on reducing negative effects of climate change than biofuels ever would, and in doing so, we will support all sentient beings on this Earth.

Let’s reset our algae narrative. There is plenty of good news to share. Opportunities abound. Refocus on the real algae industry that offers real products and services from algae. Let’s nominate individuals and organizations that understand how to change the world. “Eat Algae, Don’t Burn It.”


Are algae the greenhouse crop of the future?

Algae have the potential to become a cash crop that can provide commercial greenhouse and controlled environment growers with a stable income stream, year round. According to Robert Henrikson, a pioneer in large scale commercial algae production, Spirulina algae is a crop that commercial growers could consider adding to their greenhouse or vertical farm. “I believe greenhouse growers will be the next to incorporate algae microfarms, seeking to diversify into new products with greater income potential.”
Robert Henrikson
Henrikson’s company Smart Microfarms is currently negotiating production and marketing joint-ventures with commercial greenhouse companies in California to set up spirulina microfarms and deliver spirulina farm-to-table, direct to consumer, and direct to retail. According to Henrikson, Spirulina farming can offer a higher income stream per greenhouse area, good ROI and payback of initial investment within 2-3 years. He explains that Algae can be a great additional crop for vertical farming as well in order to create a better business model.

“Vertical farming is a good initiative, it is sexy, looks exiting and supplies locally grown product direct to the market. Yet, it is a costly way of growing and may not always create the revenues to cover the cost of going vertical. Adding a spirulina cultivation inside a small portion of an existing urban farm or commercial greenhouse farm can change this and add higher income to become more successful.

Spirulina is a high-value food supplement, sold in health food stores for over 30 years, as dried powder, in tablets and capsules. Containing the unique phycocyanin (‘algae-blue’) known for strengthening the immune system, beneficial flora and healing response, and for detoxification, anti-oxidant and anti-ageing properties.
Now with local cultivation, spirulina can be enjoyed in a new way- fresh or fresh frozen –beautiful dark blue-green with almost no taste at all. Customers can melt and blend frozen cubes into juices for green drinks and mix fresh spirulina into dishes and recipes like dips, spreads and hummus. Or sprinkle tasty low-temperature dried spirulina on salads and soups.
Spirulina can be grown successfully in ponds by recreating its natural environment of high pH, alkaline and saline water. Spirulina can also be harvested and used as a supplement for growing fish and aquatic organisms within an integrated aquaponics system.

Currently Smart Microfarms is focused developing business opportunities in the U.S and Canada. However, Henrikson believes this business model is applicable almost anywhere in the world. He hopes to bring microalgae farming to greenhouse and controlled environment growers . “We can design and install practical, affordable and scalable spirulina microfarm turnkey systems, including ponds, circulation, harvesting, processing, freezing and dehydration, products, laboratory. Variations of these microfarms have been deployed and tested. With greenhouse infrastructure in place, growers could be in operation within 6 weeks.”

Henrikson’s company can also offer innovative web-based remote sensing and monitoring systems to provide ongoing assistance to local operations for successful algae cultivation. “Small operations cannot afford an on-site experienced algae scientist to maintain successful and continuous algae cultures. Real-time web based reporting allows remote experts to guide local operators, reducing culture crashes and downtime. This system has been tested for the past two years in several locations and we are extending its capabilities.”

Green Drinks

Product Line

But Smart Microfarms can also help to distribute ‘locally grown’ algae food and supplement products to the local and regional market. “With years of experience developing products, sales and marketing, including connections within the natural foods industry, we can provide an umbrella brand for aggregating the production of small local producers of quality spirulina. We bring to market branded and packaged nutraceuticals and food products sold direct to consumers, online, direct to natural food retail outlets, juice bars and restaurants. Smart Microfarms will source product from its own algae microfarms, other quality algae farms with unique products, and facilitate and develop new farms in its network with technical and marketing expertise, ensuring superior product quality.”
