Hezinger Algaetec focuses on the development of highly-efficient bioreactors. The company uses special photo bioreactors in which phototropic (i.e. organisms capable of photosynthesis) organisms are cultivated in the right conditions. The goal is to harvest these microalgae and further process them as renewable energy sources.

The organisms used in the Hezinger Algaetec photo bioreactors are specially selected algae strains. Microalgae are the fastest growing of all plants known to man. Like all plants, algae use sunlight to bind CO2 in the photosynthesis process and produce oxygen and energetic compounds. Hezinger Algaetec has selected what is now the best organism for this purpose: Chlorella vulgaris. In order to generate the most biomass with the least possible artificial energy input, Hezinger systems use the following parameters which are applied in their technology:

• Use of a closed system for better process control and hygiene
• Use of CO2 from power plant and industrial emissions
• large volume to minimize operating costs
• use natural sunlight to optimize the energy- and CO2-balance of the final product
• Build vertically in order to reduce the floor space required in comparison to other systems

Hezinger has developed a system which works best in conjunction with three conditions for the company which wishes to produce clean, reliable biomass fuel and clean up its carbon footprint. The company should have the following three environmental conditions:

• Near CO2 emissions (e.g. coal-burning powerplant)
• Location that provides adequate long- lasting light
• Provision of fresh water

Taking all these factors into account this innovative methodology of cultivating makes it possible to harvest algae on an industrial scale.

Conversion of carbon dioxide to biomass




Pure - convert emissions

Microalgae are the most powerful converters of CO2 to energy. Feeding pre-cleaned flue gases to algae in a closed system lets them convert the CO2 photosynthetically and for that avoid greenhouse gas emissions.

Hezinger bioreactors are designed for most efficient CO2 consumption - and for that highest biomass production - on smallest required space.

In addition to cleaning up the environment and reducing its carbon footprint, the plant manager can gain tradable carbon certificates. This increases income from what may be an environmental problem today. Not only does the plant operator generate carbon credits, but he/she also produces energy through biomass. This combination makes environmental protection lucrative.

BIO - Algae in activity

Microalgae are maybe the most efficient producers of biomass.

Due to their ability to grow very fast they beat any other plant concerning biomass production.

They are much more efficient than land crops, and leave a much smaller environmental footprint.

Chlorella vulgaris is a monocellular Microalgae with a cell diameter of 5 - 10 µm. It possesses an extraordinarily good mechanical stability. Due to its high oil content and ability to grow on an industrial scale, Hezinger uses Chlorella in its bioreactors.

Algae do not compete with human and animal food supply for environmental resources. They require no fertilizers, polluting the environment and only little land to grow. Microalgae biomass represents a trendsetting possibility for the production of energetic substances.
