Use

Marenate offers an seaweed cultivation concept, with which in one win win situation does not only cultivate algae economically as so far the first enterprise, but coastal municipalities a lasting, environmentalcompatible and economic possibility is at the same time ordered, nutrient-rich waters ("eutrophierte") and before-clarified settlement waste water to prepare. The conventional procedures of the waste water treatment provided and represent for the municipalities a high financial load. These will still increase after conversion of the recent European Union water framework guideline. Like that municipalities were obligated all European Union to deliver to end of 2003 a water quality report which are respective loads gradually until 2010 around 60% are lowered, otherwise compensations to carry out would be. The past practice of the ventilation of water at great depths leads only to a complete dismantling of the died biomass and with it connected to a smell avoidance. The feeding salts remain strengthening the problem in the subsequent year in the water and.
Idea

Here MaRe offersa nate solution by cultivation of sea algae (macro algae) in closed tank systems: These can extract within a short time up to 80% of the nutrients from the surrounding water and convert to valuable biomass. Here the potential is used by in the north and Baltic Sea domestic macro algae, within a short time much, to take up as nitrate or ammonium available, nitrogen as well as Phospate. They grow 3 4 times faster than comparable land plants. The procedure works maintenance-poor, as energy source solar electricity is used. The won biomass can be used variously. MaRenate for Germany offers exclusive macro algae and alga products already now .

With support by the country Lower Saxony was built a demonstration unit and embodied in the Hooksmeer. The new procedure for the water purification is announced at the German patent office. The past investigations show one up to 80% reduction of phosphate from the Hooksmeerwasser. For the developed biomass there are various applications.
The cleaning achievement is still improved by the employment by shells. There is here a co-operation with Dr. Walter of mytilamar.
