AlgoSource develops four key areas for its industrial clients and for its consumers :

  • Microalgae production within controlled systems (photobioreactors also known as PBR)
  • Biorefinery engineering (tailored molecule extracts)
  • Creation and sale of range of natural products (check out our online shop)
  • Conception of integrated culture systems (PBR design from 1 liter to several m3)

AlgoSource Technologies: B2B – Industrial customers

AlgoSource actively develops four core activities for its international customers:

  • Microalgae production for creating a competitive advantage.
  • Bio-refinery engineering.
  • Integrated systems design.
  • Effluent recovery (CO2, nitrogen, phosphorus, waste heat, etc.).

AlgoSource Equipment

AlgoSource engineers a range of controlled production systems, called photobioreactors, available on both a laboratory and industrial scale.

Across the entire value chain…

AlgoSource is involved at each stage of the microalgae cycle: from selection and production (from a laboratory to an industrial scale), and creating value from algae (algae refining) through to the manufacture of finished goods.

Microalgae cultivation is central to the value creation process.

Bespoke production systems are needed for the photosynthetic development of microalgae. These systems need to be fine-tuned to suit the required application, the industrial operating conditions, the strain requiring cultivation, and so on.

AlgoSource Products has an extensive track record in producing microalgae and cyanobacteria on an industrial scale (especially at its Alpha Biotech production site created in 1993).

Expertise in microalgae cultivation

The Group spearheads continuous research and development into microalgae cultivation through its AlgoSource Technologies branch, whether through its involvement in specific national or international programmes, or in partnership with the GEPEA Laboratory at the University of Nantes (CNRS joint research unit), which over the last 30 or so years has carved itself a reputation as an expert in the bioprocess engineering of microalgae.

The major criteria that influence how the production system is engineered include the target market and application, the operating environment and biological needs, all of which as part of an industrial ecology strategy that factors in the potential effluent types that can be jointly recovered (CO2, heat, nitrates, phosphates, etc.).

Sale of controlled production equipment

We also offer a range of professional controlled production tools (from a few litres to several cubic metres).

Ever since AlgoSource was founded, we have been actively involved in a number of projects on a regional, national and European level as well as overseas (Latin America and Asia) as part of our constant determination to develop and transfer our end-to-end microalgae expertise within benefit-sharing collaborative arrangements.

Examples of our national and international projects:

  • SYMBIO2 project: Urban algaculture in the form of bio-façades (photobioreactors) to improve thermal insulation and effluent management in buildings (water, CO2, heat, etc.): the urban ecology concept of tomorrow’s world.

Objective: Transform urban algaculture into a natural insulator for reducing the environmental footprint of buildings.
