Algae for a greener world

The origin of oxygen on the planet started 2.7 billion years ago with cyanobacteria, the first microorganism capable of transforming CO2 into oxygen. Rocks found 2.4 billion years ago showed that oxygen already reached the atmosphere at that time. These very old oxygen producers evolved into algae 1.2 billion years ago, first into red and brown algae which have a more complex cellular structure, and finally into green algae. Now, more than 50 000 species of microscopic algae, or microalgae, have been found on the planet, along with 12 000 species of macroscopic algae, also called macroalgae. As a direct descendant of green algae, the first land plants appeared on the planet only 0.475 billion years ago.

Compared to land plants, algae, and especially microalgae, usually grow much faster and do not need arable lands to be produced. They can be grown on sites that are not competing with food production and especially near CO2 emitting industries for carbon capture. A large panel of bioproducts can be produced from algae, but its most striking virtue has been found in its nutritional capability, several species are really considered as superfood.

Carbon capture

 

Microalgae are not only the oldest oxygen producers and CO2 sequestrators on the planet, they are also among the most efficient. Their photosynthesis apparatus is so efficient that they can reach productivities up to 150 tons/ha/year while land plants is usually 5-10 times less efficient, typically 10-30 tons/ha/year.

Microalgae can be used as an efficient alternative for bio-based carbon capture, especially for valorizing and capturing CO2 produced by other industries.

Circular production systems

 

Sustainable algae production needs to be envisioned through circular production systems. Closing the loop can be done at different levels: by using waste streams from other industries such as CO2 or heat, using nutrients from recycled sources, or recycling streams within the algae production system such as water, nutrients, and CO2.

In this vision of eco-efficiency, the transformation of algal biomass towards specific products needs to be thought to minimize algal wastes by valorizing co-products of interest and using the residual wastes to produce energy.

Customized algae profile

 

By applying the right culturing conditions, it is possible to promote the production of specific compounds of interest within the algae to meet the desired needs.

The nutritional profile of the algae can be customized to promote the production of high quantity of proteins (more than 60% in content for certain cases), specific vitamins and antioxidants of interest, lipids (e.g. Omega 3), or biomolecules and biopolymers.
