engineering and Process of Microalgae

Micro-Algae

Algosource/Micro-algae

A new vegetal resource: microalgae

50% of Earth’s biomass, 100 000 known species

earliest precursors to plant life

complete set of photosynthetic machinery

biochemical production of valuable synthons

Microscopic aquatic species in permanent contact with their nutrients
At the base of the alimentary chain (vegetal plankton)‏
Consume CO2 and produce O2, as any other plants : when cultivated the limiting factor is usually light, or CO2

n CO2 + n H2O + light è (CH2O)n + n O2

Multiplication in few hours in lab conditions
A natural adaptability that can be used industrially to induce the production of specific metabolites

Production of Bioenergy: Biogas: communities, farms, industries

Third generation biofuels

Food: Food: algae, proteins, omega3

Animal Nutrition: Aquaculture, proteins, lipids

Production of biomaterials: Starch plastics renewable

Recovery of waste: CO2

Heat, sewage sludge ...

MICRO-ALGAE ADVANTAGES

•Outputs 5 to 10 times larger than terrestrial plants, non-arable lands

•Bioconversion of CO2

•Recycling of industrial effluents: CO2, nitrates, heat

•Limited water consumption

•Production without pesticides and herbicides

•A local, controlled , perennial resource

On the whole the environmental assessment is extremely positive
