5 surprising applications of growing micro algae

Micro algae open up a world of possibilities when it comes to obtaining sustainable and healthy renewable energy , raw materials or active ingredients for a myriad of uses, such as food, cosmetics or pharmaceuticals.

Produce biofuels

Micro algae can produce biomass for the manufacture of different types of biofuel, such as biodiesel, ethanol, methane or hydrogen. Its production usually begins with the selection of the species of micro algae to be used, generally from those available in the local environment.

Subsequently, the design and implementation of the cultivation system is carried out, periodically harvesting and extracting the oil from it. From this, finally, the raw material used in the unit is obtained production of biofuel .

As producers of green fuel, it is decisive that micro algae are photosynthetic microorganisms with a unicellular structure, since thanks to it they grow rapidly. Basically, they reproduce through photosynthesis, converting sunlight into chemical energy naturally, that is, as part of their life cycle.

Polluted water cleaning

Among other advantages of the cultivation of micro algae is worth noting its ease when growing them . In addition to being able to develop in tanks to be located in a thousand places, such as roofs, warehouses or spaces specially designed for this purpose, they feed on nutrients that are pollutants.

Among other sources from which to obtain them, in addition to CO2 from the air, we find wastewater a very interesting resource. On the one hand, it allows the use of water not suitable for human consumption for its cultivation, while it can be cultivated in natural places that have been solved to improve the quality of degraded water.

Sustainable cosmetics

The cultivation of cyanobacteria makes it possible to improve cosmetic formulas , providing greater tolerance to possible allergies, that is, minimizing adverse reactions and also achieving greater moisturizing power.

At an environmental level, it helps the formulation to be biodegradable , although in the end everything will depend on the rest of the ingredients, of course. Theirs, however, is designing entirely biological formulations to maximize their potential benefits.

CO2 absorption

Another of the most outstanding utilities of micro algae takes advantage of their action as carbon dioxide sinks. The explanation is very simple, since they are organisms that capture solar energy and accumulate it in their fats through photosynthesis, thereby absorbing CO2 and emitting oxygen.

By absorbing or trapping that CO2, we clean interior or exterior atmospheres and obtain nutrients for the micro algae. It is a clean technology that does not generate toxic or dangerous waste, providing very high yields. From these micro algae, they can also be used in very different processes.

Climatize and insulate buildings

Obtaining green energy for the generation of energy for heating and air conditioning is the objective achieved in the installation that we find in an avant-garde four-story building that rises in the city of Hamburg, in Germany.

Named Bio Intelligent Quotient house produces energy through its original facade, partially covered with thin glass panels that make the role of culture containers for automated from micro algae .

The location on the façade is key, as this can give them the sun throughout the day (they are adjustable panels), necessary to carry out photosynthesis and thus grow faster, while acting as an insulator from cold and heat, in addition noise, which also achieves greater energy efficiency.

Endless possibilities

These five uses are far from exhausting the possibilities of exploitation of micro algae . Among other applications, we can use them as raw material for the manufacture of biofertilizers , food supplements, vitamins, pigments and a long list of compounds with great applications in very different industrial sectors.

What’s more, its cultivation allows multiple exploitation, with which the advantages are even greater. On the one hand, microalgae can absorb CO2 from industry greenhouse gas emissions to later produce one or other products.

The possibilities continue to increase as new processes are discovered or existing ones developed . From producing fats, oil, natural dyes, fatty acids, oil, sugars, organic fertilizers or antioxidants, let’s say, to the processing of biomass for energy.
