Cultivation technology

Cultivation of phytoplankton is an extremely difficult task that requires knowledge and continuous training to achieve a qualitatively stable product, as well as investment for technical excellence and production safety.

Since its inception, the company has a high level of know-how in Spirulina cultivation, co-operating with a team of high-profile experts in Greece and abroad engaged in algal biotechnology and especially Spirulina from 1983 (Dr. I. Tzovenis) and in the commercial cultivation of Spirulina since 1996 when the first production plant was established in Greece.

 Under the guidance of P. Anastasiadis, architect engineer and founder of the company, the company developed high-quality facilities and infrastructure for both cultivation and packaging and has created a premium natural product following high standards at international level. 

Additionally, the company participates in research projects with Universities and research institutes for the continuous improvement of their know-how and technological infrastructure.

Facilities and infrastructure

Facilities and infrastructure

The company possesses at Therma an area of 22,5 acres with 7,5 acres of arched greenhouses for the cultivation, harvesting and drying of Spirulina. In its greenhouses, four cultivation tanks of 400 m2 each are housed and two solar dryers of 200 m2 each. It possesses a building that houses the pharmaceutical packing, product stores, offices and a lab.

Recently, the company commenced a strategic expansion with its subsidiary SSPIRULINA NIGRITA ANASTASIADIS X. at the nearby site of Alepou (Therma Nigrita), which has an area of 4,6 hectares with an installation of 31,5 acres of high-standards glass greenhouses. Currently, it has built four raceway ponds of 850 m2 each and a double greenhouse of 1000 m2 for solar drying of the product. It has a special harvest area with a self-built filtration device using a vibrating screen, auxiliary areas and infrastructure for use of the geothermal energy and carbon dioxide that springs in the area. It also has a large 2-storey building of 560 m2 that houses the food-grade packing centre, offices, warehouses and a lab.

The production capacity of the Spirulina Nigrita group today exceeds 20 tonnes, with the prospect of exceeding 100 in full growth.
The company has access to a 1345 acres geothermal field for 35 years capable of pumping 200 m3/h geothermal fluid of medium temperature (about 60 ° C) and high purity (> 99 %) of carbon dioxide, i.e. environmentally friendly natural resources necessary to produce Spirulina year-round.

The farm is located within the Serres plain (North Greece) that has uninterrupted sunshine throughout the day for over 300 days a year. In combination with the geothermal field that provides continuously heat and CO2 the location is most suitable for the cultivation of an energy demanding phytoplankton like Spirulina.
Cultivation of Spirulina is carried out in raceway ponds constructed with modern standards housed in greenhouses that ensure the protection of the crop from natural and man-made adverse factors.

The production standards are in line with the requirements of the legislation and are certified by the Ministry of Rural Development and Food as an inland fresh aquaculture plant.

Processing and packaging

Processing and packaging

Harvesting by screening and controlled sun-drying ensures the natural quality of the product while preserving its delicate ingredients (proteins, carotenoids, vitamins), its taste and odor that are otherwise considerably degraded.

Formulation of the final product takes place in three distinct forms: tablets, powder and flakes. The bulk is tableted into a 100 % Spirulina product without excipients or impurities, making it a 100 % natural product in both production and formulation. The whole procedure is carried out in the company’s pharmaceutical packaging.
