Hey Steemians, I hope that you guys are all doing well. About a week ago, I wrote a post on the Blue economy titled “Introduction to the Blue economy”. This was an opportunity to review its history, how it works and even some two concrete use cases that derive from it. Today, we will review the fundamental economical principles of the Blue economy as well as two concrete examples that use the Blue economy approach.
Build local, Buy local
The Blue economy is not against globalization, but is against the perverse effects of globalization as they manifest today. The idea behind the Blue economy is to create value from what appears to be nothing or a “waste” (See the coffee example from my previous post). An entrepreneur in the Blue economy should always use what is available locally, as it is done by the nature. To give you an example, termites all over the world can build their nest at 81 degree Fahrenheit and 61 % humidity to prevent fungi from proliferating, no matter which hemisphere or region they are located in. They always achieve this technical prowess with what is available locally.
To give you another concrete example, let me talk about bamboo houses. Visionary architects such as Linda Garland, Simon Velez, showed that bamboo houses are a good alternatives for local communities that have bamboo farms, as it can be attractive, much more affordable and renewable compared to concrete and steel. Also bamboo houses are known to best resist earthquake due to their structure. Simon Velez designed the largest bamboo structure in Manivalez, Colombia, which resisted two severe earthquakes. Simon Velez was able to design a two- story low cost housing for only $12,000. 
The Blue economy demonstrates that there is cash flow even in very poor communities. It is mentioned in the Blue economy 2.0 that, in 2004, Prof C.K. Prahalad and Stuart Hart demonstrated that 3 billion people who live with $2.50 a day represent 2.7 trillion in cash every year . Now the problem is that the cash flow from those communities is quickly drained out everyday. What alternative is there then? Micro-economies. The Blue economy believes in micro-economies to rebuild local communities. Using the “Build local” approach, people in sub-communities should buy to business locally so that their cash flow can stay in their economy, grow and empower them. Note that the Blue economy is not against exportation of goods at all. In fact, many companies that have used the Blue economy approach have exported quite a good amount of their goods. But the fundamentals should be there (“build local then buy local”) so that the community can mature and be able to trade. Otherwise, problems might arise such as the Argentina case. Argentina can produce 10 times more food than its population needs. However, there are 750,000 children malnourished in Argentina due to its excessive exports .
The spirulina case
Spirulina is an algae that has many healthy properties and that can provide food security in communities. It mainly needs two conditions to be farmed: high humidity and CO2. A company named Energaia  in Thailand followed the Blue economy principles and was able to urban farm spirulina on hotel rooftops. Now this was a clever approach given that in hot humid areas such as in Thailand, hotels have many, many, many air conditionners (CO2) !! So basically they were able to farm spirulina 24/7 thanks to that approach and today this company has a solid business model. They are able to produce much cheaper spirulina in terms of market price. Hotels that partner with Energaia are able to serve spirulina smoothies or spirulina noodles to their customers. Today, Energaia is the most efficient producer of Spirulina on the planet ! Their goal is to be able to make their spirulina available worldwide . You guys can imagine the local impact in terms of job creation and revenues.
The thistle case
The company Novamont in their bio-refineries in Sardinia in Italy has been able to make lubricants, natural herbicides with commercial values, elastomers, lubricants, bio-plastics all from thistles  . At the inception of this project, they had to deal with abandoned bio-refineries that were full of thistles (which are usually perceived as just weeds by many). Instead of paying farmers to remove the thistle, they were able to use what was available locally and to produce multiple items of value. This is one of the core fundamentals of the Blue economy.
In this post, we were able to review some fundamentals aspects of the Blue economy principles. We were also able to discuss two relevant cases. In future posts, we are going to discuss more Blue economy use cases.
