Duckweed project

On the estate het Lankheet in Haaksbergen (500 ha) there has been a cooperation since 2005 with Wageningen Universiteit/Plant Research International (WUR/PRI). A sustainable reed purification filter has been realised the produces ecological water for nature development and biomass for green energy. At the moment an new phase of the filter is under testing, namely a production unit for duck weed (Lemna) for extraction of proteins. These are of higher quality than the proteins from soy. This type of production, once upscaled, could make a major contribution to improvement of climate conditions (meat and fodder replacements and therefor a reduction of CO2  and and reduction of the decrease of vulnerable ecosystems like rain forests by decreased land use for soy production). 

Together with the company ABC Kroos (Aquatic Biomass Chemistry) a project was started that gives het Lankheet the first conditioned open air production of duckweed. In this project Amersfoort Coöperative University has the role of testing and developing harvest methodes of duckweed together with B-ware from Nijmegen and Colubris from Winterswijk, and growth and nutrient monitoring.

The technical refinement of duckweed takes place in Groenlo (Gelderland). The proteins from the duckweed can be used for food purposes (meat replacements and additives) but also for industrial non-food applications like glues. The leftovers are sold as fodder to the agricultural sector. The provinces Overijssel and Gelderland financially support this project through their Agro-Food programmes. With Overijssel based companies like Encko and de Eendracht, cooperations have been started (food) and with the Haaksbergen based Unipro (the most sustainable chemical company of Europe) the application of duckweed proteins in glue is undertaken.
