5. References5.1See attached filed “REDstack paper.pdf”5.2“Last thursday we talked about whether the brackish effluent of a Blue Energy plantwas thought to create a problem, but that a recent study from Arnout Bijlsma andothers showed that this was less of a problem than expected. I asked them why andthis is what they said:They looked primarily at the problem of recirculation, which means that you let yourbrackish effluent out in a location near the location from where you pump in eitherthe salt water or the freshwater. They showed that if you let the brackish effluent outon sea, it will not be a big problem, because of the sea water flow along the coastfrom the south to the north. This means that the brackish water transported away tothe north and that there is a constant new supply of salt water.The same principle is true when you let the effluent out on the Noodzeekanaal (atleast when the sluices are open) since there is continuous supply of new freshwater.So recirculation seems to be not the problem.Secondly, they haven't studied the possible adverse affects of brackish water on theenvironment. Normally the fresh water and the saltwater are mixing as well, so on ahigher scale level, it shouldn't make much difference if you put an BE-installation inbetween.However, on a smaller scale you might create different salt concentrationslocally, which might have effect on local ecosystems. They have not studied this indetail and should be in the future.As they see it, the biggest problem is to find high salt concentrations and purefreshwater problem for the intake. The BE-installation works best if the difference insalt concentrations is high. However the sea water near IJmuiden has a lowerconcentration than average due to the mixing of the freshwater from theNoordzeekanaal, and vice versa, the Noordzeekanaal is not pure fresh due to mixingof salt water.So where does this leave you? Well, this study tells us a brackish water might be not aproblem in terms of recirculation, however we are not sure how it effectslocal ecosystems, or whether it will be accepted by society. Secondly, we shoold looktowards other points of intake for instance, cooling water from factories...I suggest you think about these insights and take them into account while writing theproposal and discuss it with Marco en Hans.The bright sight is: since the problemseems to be less that expected, the chances for you to actually get commitment fromthe decision makers are bigger!”Rutger van der Brugge, Deltares5.3See attached file “lozers afvalwater koelwater NZK.pdf”5.4http://www.treehugger.com/files/2006/08/happy_shrimp_fr.php“Happy Shrimp Goes Local in Rotterdamby Petz Scholtus, Barcelona, Spain on 08.10.06Soon we Europeans can enjoy local and happy shrimp from the Netherlands. No moreclocking up on Food Miles when you fancy fresh shrimp, no more deep-freezing & overpackagingand no more polluting of mangrove forests by existing shrimp farms in Asia. Bass23
& Gill BV have came up with e new business idea: the Happy Shrimp Farm; the first tropicalshrimp farm in Europe. They call it a new eco-industrial company that benefits the economyand the environment. Here is how:The Happy Shrimp greenhouse-enclosed Farm in Rotterdam uses the waste heat (otherwisereleased into the air) of the neighbouring power plant to warm the farm. A biological filterbed makes sure the waste streams of the farm don’t pollute in order for future generationsto enjoy shrimp happily in an untouched environment. Another advantage of a shrimp farmin Europe is that the shrimp available is at its most freshest as well as safe to eat (see FoodSafety page). Happy Shrimp made it their responsibility not just to farm shrimp eco-friendlybut also to tell people about industrial ecology, sustainability, energy use, healthy food andjoyful lives. Their web site is a great and clear source of information full of happy shrimps.To feast on Happy Shrimp you have to wait until March 2007 when they will hit the market.The construction of the farm started in April this year and the official opening is inSeptember followed by the Night of the Prawns Party. In the meantime you can Shrimp UpYour Life with the Happy Shrimp Merchandise: 100% organic t-shirts, stickers, or a HappyShrimp Eco-Sphere; a NASA developed self-sustaining living environment for 3-4 small brightred shrimps! Great how far you can take a sustainable shrimp locally! ::Happy Shrimp via::Springwise”5.5See example at http://www.aquaphyto.com/5.6See attached file “WageningenPresentation saline agriculture.pdf”5.7“Nice project, and regarding to your question if brackish water is in our focusof interest: no, not really, but besides we’ve done some work withaquaculture in this kind of environment.I think that the production of brackish water can be used to create a naturereservation area. Here in Zeeland we have about 900-1000 hectares of saltwetland on former agricultural land, which was already difficult (brackish)for the traditional crops. We tried some aquaculture with the algae in thiskind of area as food for shellfish, but not very successful. The main issue wasthat the salinity was too low, for shellfish aquaculture you need at least 20promille salt, and also the algae in these areas where not of any food value.You will need higher salinity.There might be possibilities for silt vegetables or ragworms, but these arenot our very core business.” - Marco Dubbeldam, Stichting Zeeschelp5.8See attached file “AlbertGoedbloedThesis.pdf”5.9See attached file “negenborn-multi-agent-water.pdf”5.10See attached files “Schutgegevens 2009_01-06.xls” and “tunnel depth.doc”5.11See attached file “Roundtable 21st January.ppt”5.12See attached video “BLUE ENERGY”24
