Fish Radio has been following Tidal Vision, a team of eco-entrepreneurs from Juneau who are using Alaska crab shells in fabrics, water filters, wine refiners and more.  Their method of extracting chitosan from crab shells in a closed loop, chemical free way is a world first, making Tidal Vision the only maker of chitosan products in the USA.

As they build  up stockpiles of chitosan and hone equipment and methods at a pilot plant near Seattle, a first product to hit the market is Tidal Grow –

 It’s an organic nitrogen source, it’s got 11 essential plant nutrients in it, for some application sit can be a ph adjuster for the soil and reduce the need for other soil amendments, it’s loaded with calcium.

Craig Kasberg is Tidal Vision’s Captain Executive Officer.  Customers also are buying bags of dried chitosan flakes for water filtration.

 We’re supplying a couple companies in Washington that process storm waters and chitosan is used for that because it can bond to the toxins and be a safe way to treat the water on its way into Puget Sound.    

In its liquid form, Alaska chitosan is serving another customer – wines.

In its liquid form they use the same process to clarify it to settle out some of the solid particles in the wine as a finishing agent. It’s the same concept. 

Tidal Vision also has teamed with  Floral Soil Solutions  to make bio-based flower foams.

They make an all natural foam for florists that is in Whole Foods across the country and several other   big flower outlets to replace the petroleum based screen foam that’s been the industry standard for about 40 years. It’s done with all natural, cellulose based plant fibers.  

Also in the offing:  Tidal Scrub – a chitosan-based kitchen sponge that naturally kills bacteria.

There is a common saying that there is more bacteria in your kitchen sink than in your toilet. That grabs  people’s attention as an example of how this chitosan can really make a difference in day to day life. 

At the same time, Tidal Vision is perfecting its ChitoSkin fabrics and working with Grundens’ product development team. Kasberg says the ultimate goal is to bring the entire operation to Alaska within two years.

Prices for chitosan, he says, can range from  $10 to $30,000 a pound, up to $150,000 a pound for pharmaceutical grades.

Fish Radio is also brought to you by Ocean Beauty Seafoods, an Alaska corporation proudly supporting Alaska’s coastal communities and the Alaskans who depend on fishing for their livelihoods and culture.    In Kodiak, I’m Laine Welch.
