Inhouse Farming - Feed & Food Show

Part of AGRITECHNICA: 12 - 18 November 2023, Hanover

Pioneering new ways of farm & food

Controlled Environment Agriculture – global food security through new agricultural production systems is one of the central tasks of the future. "Inhouse Farming - Feed & Food Show" is the DLG's new platform for the agricultural and food systems of the future. Closely networked with agricultural practice, it offers technical information, perspectives, innovations and business - from feed to food.

Algae

Cultivating algae in closed-loop systems is a promising method of producing them in a controlled environment. In contrast to cultivating algae in open water systems, closed-loop systems offer increased productivity and control over the quality of the algae.

The types of algae most frequently cultivated in closed-loop growing systems are Chlorella, Spirulina and Haematococcus pluvialis. Chlorella is a green algae that is rich in protein, vitamins and antioxidants. Spirulina is also a green algae and contains high quantities of protein, iron and vitamin B12. Haematococcus pluvialis is a red algae that is rich in astaxanthin, a powerful antioxidant.

Various technological methods are used in the closed-loop algae cultivation system. These include the tube and plate system, the photobioreactor system and the membrane system.

The tube and plate system is the simplest method; it consists of flat tanks or tubes in which algae are cultivated. The light is fed in from above and nutrients are introduced into the water by means of aeration.

The photobioreactor system is a more advanced method and consists of a self-contained system with a special lighting system. This method enables increased productivity and better control of the algae’s growing conditions.

The membrane system is another advanced method that enables the separation of algae and water by means of membrane filtration. Thanks to this, the algae can be harvested more efficiently and the water can be reused.

Closed-loop algae cultivation offers numerous advantages such as increased productivity and better control over the quality of the algae. Algae can be used as food supplements, feed for livestock or cosmetics and in bioenergy production. Algae cultivation in closed-loop systems offers a sustainable and resource-efficient option for producing these valuable resources.
