Marine microalgae encompass attractive properties for biofuel production. The fat extracted biomass that is left behind after biofuel is made may be a promising carbon-neutral animal feed supplement.
Algae aka ‘green coal’ and ‘green protein’

When you read about algae there is often a discrepancy between macro- and microalgae. Macroalgae are commonly known as “seaweed”. The word “macro” means big so think of a big plant that can be found in the sea. Microalgae are often called phytoplankton. As the word micro means small, these plants are smaller than the seaweed plants, so small, that you can’t see them with the naked eye.

More sustainable

Microalgae are a potential source of renewable energy, and they can be converted into energy such as biofuel oil and gas. They sometimes call it the ‘green coal’, as the algae form a more sustainable alternative for the current fuel sources we use. The development of CO2-neutral fuels is one of the most urgent challenges facing in our society, to reduce gaseous emissions and their consequential climatic changes, greenhouse and global warming effects.
