Eerste blauwalg gesignaleerd in Almere Haven

Almere Haven. 19 juni 2007.

Eerste blauwalg gesignaleerd in het Haven gebied.

De geplaatste schermen aan de kop van de haven hebben de blauwalg concentratie in de haven, zoals door ons verwacht, niet kunnen voorkomen.

Rijkswaterstaat heeft beloofd de inwoners een week van te voren te waarschuwen. Is men dit vergeten?

(inmiddels heeft Rijkswaterstaat de blauwalg ook ontdekt; via onze site? – 20 juni 2007).

Wordt het niet tijd dat de gemeente ons informeert over de stand van zaken met betrekking tot het onderzoek dat naar de bestrijding van de blauwalg in Wageningen en bij het RIZA wordt gedaan?

En nog belangrijker voor de restaurants en de omwonenden aan de haven de resultaten van het onderzoek naar de stankbestrijding!

Verbluffende resultaten met EM-modderballen in waterbassins van kwekers rondom Boskoop

Dick van der Maat van de Acer kwekerij in Boskoop waar we 27 april te gast waren, meld ons het volgende:

“De modderballen werken heel goed tegen de algen. In het grote bassin was een explosie van algen (pomp defect). Ik heb er 10 modderballen ingegooid en binnen enkele dagen zag je al dat de algen naar de bodem zonken. Het water is nu weer redelijk helder en de koi vissen hebben het naar hun zin.

Na een aantal proeven bij collega kwekers met modderballen in hun waterbassins is het resultaat verbluffend. Totaal geen algen meer.

Ik denk dat veel kwekers het in de toekomst gaan proberen . Ik zou graag van de EM vereniging de exacte procedure vernemen hoe je deze ballen maakt. Er zijn verschillende versies maar de ballen van Almere werken goed.”

Bericht van Edwina Molina, gemeenteraadslid Almere, over de Blauwalg

Blauwalg

Na een vrij zachte winter staat de zomer voor de deur evenals de angst voor blauwalg overlast. Het college heeft € 400.000 begroot om tijdig de blauwalg te kunnen signaleren en voor het opruimen van de dode algen. Maar wat te doen tegen de stankoverlast? Ook de buurtbewoners en de horeca hadden last van de stank door de vrijkomende misselijk makende gassen. Hier is duidelijk geen rekening mee gehouden.

Wij betreuren het ten zeerste dat het college heeft nagelaten om tijdig te laten starten met onderzoeken naar de bestrijding van de blauwalg en onderzoek naar de bestrijding van de stank zelfs achterwege heeft gelaten. Als het college en Rijkswaterstaat het initiatief van de burgers in Almere Haven serieus hadden genomen dan had dit onderzoek nu afgerond kunnen zijn. Rijkswaterstaat heeft helaas gekozen om de burgers te ontmoedigen. GroenLinks fractie zal met haar helikopterview het college en Rijkswaterstaat volgen in hun pogingen om de blauwalg op te ruimen. Het bestrijden lijkt vooralsnog een brug te ver voor de Rijkswaterstaat.

Micro-organismen in beeld

During the past three years, microorganisms have begun to be more actively enlisted for industrial production. Microbes, after all, are essentially miniature chemical factories: they ingest materials, break them down with enzymes and turn out byproducts. Brewers and pharmaceutical manufacturers have exploited microorganisms for years, but now they are being drafted for other types of work. Some companies have also figured out ways to re-create microbial processes in the lab in the growing field of synthetic biology.

Making ethanol out of biodiesel byproducts

E. coli could gobble up a common byproduct of biofuel production and turn it into another green fuel, ethanol, according to Rice University professor.

Rice University researchers say that microbes can help us get more biofuel for the buck.

Microorganisms can be used to metabolize glycerol –one of the primary byproducts in converting vegetable oil or animal fat into biodiesel–into high-value products, said Ramon Gonzalez, the William Akers Assistant Professor in Chemical and Biomolecular Engineering.

Gonzalez and a group of students, for instance, have identified a process in which Escherichia coli, in an oxygen-free environment, will convert glycerol into ethanol. The strain of E. coli currently being used in the experiments isn’t genetically modified or enhanced, which could further enhance yields.

The glycerol could also be converted into different types of industrial acids, which could even be more profitable than ethanol.

The research, which is attracting investors and companies interested in licensing the technology, could help take some of the risk out of the growing biofuel business. Start-ups and established companies are sinking hundreds of millions of dollars into building biodiesel refineries and ethanol plants.

Unfortunately, turning a profit isn’t easy, even with subsidies that range from 50 cents to $1 a gallon. Both biodiesel and ethanol are dependent upon feedstocks such as palm oil, sugar cane, and corn, which can fluctuate wildly in price and erode margins. Corn has doubled in price, from $2 a bushel to $4 a bushel, in the U.S. in the past year and whacked the profits of ethanol producers. Increased biodiesel demand is expected to make cooking oil prices spike in the coming years.

To remain economically viable, these companies have to be able to sell their byproducts. In biodiesel, that’s become tough to do because of the sudden glut in supply. Glycerin (also known as glycerol), which is sold to cosmetics companies, went for about 25 cents a pound 18 months ago, said Gonzalez. Now it sells for about 2 to 3 cents a pound–when sellers can find buyers. For every 10 pounds of biodiesel produced, refiners are left with about a pound of glycerin. (Oil in industrial processes gets measured in pounds.)

"This could help biodiesel a lot," he said. "When they design their economic models, they count on selling the glycerin."

Ethanol produced from glycerin could also be more economical than producing it out of corn, the main feedstock for ethanol in the U.S., or than cellulosic ethanol, which is made out of wood chips and waste vegetable matter. Gonzalez hopes a prototype production process for making glycerin ethanol will be in place by the end of the year, meaning it could come to market earlier than cellulosic ethanol. Mascoma will try to open a small cellulosic plant by early 2008 and New Zealand is investing in the concept. But most believe cellulosic ethanol is still at least a few years away.

During the past three years, microorganisms have begun to be more actively enlisted for industrial production. Microbes, after all, are essentially miniature chemical factories: they ingest materials, break them down with enzymes and turn out byproducts. Brewers and pharmaceutical manufacturers have exploited microorganisms for years, but now they are being drafted for other types of work. Some companies have also figured out ways to re-create microbial processes in the lab in the growing field of synthetic biology.

Cambrios Technologies has come up with a biologically inspired enzyme that can be used to add insulating layers to semiconductors. Meanwhile, companies such as LS9, Gevo and Synthetic Genomics are trying to harness microbes for energy production.

And why use E. coli, the microorganism usually associated with stomach pains? It’s one of the most extensively studied microbes, and several techniques for genetic modification have already been developed with it. Gonzalez and others call it the workhorse of microbiology.

Excursie EM Vereniging naar Acer kwekerij in Boskoop

Uit een enthousiaste reactie:

Middels deze e-mail wil ik u bedanken voor het organiseren van de excursie naar kwekerij D. van der Maat.

Ik heb volop genoten van het bezichtigen van het aanwezige plantmateriaal, maar vooral door de mogelijkheid om vragen te kunnen stellen aan de professionals betreffende EM.

Wij gebruiken EM nu twee jaar in onze tuin en zijn er van overtuigd dat EM een goede bijdrage levert ten aanzien de gezondheid van het bodemleven, plantmateriaal en de omgeving.

Dankzij de excursie van gisteren gaan we nu zeker een stap verder om onze bodemgesteldheid (klei) sterk te gaan verbeteren m.b.v. de EM-Bokashi grond:

EM Bokashi en Ostrea zeeschelpenkalk en Edasil klei-mineralen.

Kortom deze excursie heeft er zeker aan toe bijgedragen dat onze EM-bakens (wederom) verzet gaan worden…

Nogmaals hartelijk dank
