 Ravida on todella huomioida, joka on lisäksi, että voidaan arvoi kohdella kohdella, ja haluaa kovaa hienojen kohdella, joka on kohdella kohdella acidin, kohdella uudelleen kohdella, ja hieno kohdella acidin ja anamonioon kohdella. Ja tämä on jopa kohdella kohdella, josta ei ole technology yet in a market, and this makes possible to maximise the recovery from the waste for the stream. So we are very excited about it. And then what comes to peltixy, this is also a potential step in a polishing step in the end of the treatment plant, which makes possible to adjust the effluent quality to very low figures and that way help to prevent eutification in the peltixy. And this bonus return program is very interesting for us because we are able to meet potential clients, potential municipalities and also potential end users, which are very important to know because otherwise you are not making things which are fulfilling the needs of the clients on both sides. And then on the other hand the technical development needs always a sort of third-part evaluation and that's one opportunity in this program to get that type of support for our thoughts and maybe some new ideas which we haven't found yet, so that's one value of bonus return.
