In cooperation with the Wildau University of Applied Sciences, ERK has researched the material and energetic use of algae in the Biophotonic Combined Energy System project (BCES). The BCES is a closed cycle in which microalgae are produced, preferably in pipe systems. The mass of microalgae is further processed to finished products in follow-up processes. These products can be used as additives or as finished products in foods, biogenic colorants, pharmaceutical and cosmetic products.
The direct energetic use of the mass of microalgae is basically possible, but it also needs to be converted into biogas or bioethanol. Preferably, however, only the energy generated from excess material from the respective follow-up processes is used.
More on BCES
The core process of this procedure takes place in the photosynthetic system of the algae cultures. Carbon dioxide is split into carbon and oxygen by the microalgae with the help of sunlight. The microalgae incorporate the carbon into their own metabolic processes, while discharging oxygen as waste. Microalgae are currently mainly being cultivated in semi-continuous processes, where the gaseous phase is continuous and the aqueous phase is discontinuous.
Always one step ahead
R&D have always been one of the main cornerstones for ERK Eckrohrkessel GmbH. From the very beginning, special importance was attached to the sparing use and responsible management of available resources. This also concerns the consumption of energy sources during plant operation, the material consumption in manufacturing energy conversion systems, and the impact on the environment.
