In Canada l’energia si ottiene anche dal letame delle mucche

La ricerca nel campo delle energie alternative sta compiendo notevoli passi avanti. Numerosi, infatti, sono i progetti e gli esperimenti messi in campo da scienziati di tutto il mondo nel settore del solare, dell’eolico ma anche di altre forme innovative di energia come la produzione di carburante ad opera di batteri o a partire da rifiuti organici e non.

L’ultima, in ordine di tempo, arriva dal Canada: produrre elettricità dal letame. Nell’Ontario un allevatore di mucche da latte, Laurie Stanton, ha deciso di limitare gli sprechi all’interno della sua fattoria utilizzando il letame prodotto dalle vacche per produrre energia.


L’idea in realtà non è nuova, già in diversi paesi il letame, insieme ad altri rifiuti, viene impiegato per la produzione di energia ma gli impianti e il processo di trasformazione sono il più delle volte primitivi. Questo soprattutto perchè gli impianti hanno un costo molto elevato e per risultare vantaggiosi necessitano di agricoltura ed allevamenti su larga scala. La fattoria di Laurie Stanton, con le sue 750 mucche, è la più grande per la produzione di latte in tutto il paese. Si calcola che ogni vacca produce letame che permette di ottenere una quantità di energia pari a quella prodotta da tre lampade da 50 watt costantemente accese. Il progetto di Laurie Stanton, che gode della collaborazione dell’University of Western Ontario’s Institute for Chemicals and Fuels from Alternate Resources e del Ministry of Research and Innovation, è finanziato dal governo dell’Ontario per 5 milioni di dollari.

Il processo di trasformazione prevede una prima frase in cui il letame viene pulito e incanalato in una serie di tubi di scolo dove viene mischiato con altri rifiuti alimentari. Successivamente il composto viene riscaldato all’interno di un bollitore e sottoposto ad un processo di fermentazione dal quale viene ottenuto del gas metano. Il gas, risalendo in superficie si immette in un generatore dove viene bruciato per produrre energia. L’elettricità ottenuta viene utilizzata per alimentare l’intera fattoria, compreso l’impianto di trasformazione del letame, e la restante energia va ad alimentare il sistema elettrico del paese. Infine, i liquidi inutilizzati dal processo vengono impiegati come fertilizzanti mentre il matriale solido avanzante è utilizzato come lettiera per le mucche.

Si stima che se il progetto continuerà ad andare a buon fine la fattoria di Stanton produrrà circa 1,3 megawatts sufficiente ad alimentare 800 abitazioni.

  1. Non capisco dove sia la notizia sensazionale.
    In italia si usa “comunemente” e ci sono gia centinaia di aziende che sfruttano il letame per produrre energia elettrca, calore e raffrescamento.
    Cerchiamo di non essere sempre esterofili.

    Salutio

  3. Hands down, Apple’s app store wins by a mile. It’s a huge selection of all sorts of apps vs a rather sad selection of a handful for Zune. Microsoft has plans, especially in the realm of games, but I’m not sure I’d want to bet on the future if this aspect is important to you. The iPod is a much better choice in that case.

  7. Between me and my husband we’ve owned more MP3 players over the years than I can count, including Sansas, iRivers, iPods (classic & touch), the Ibiza Rhapsody, etc. But, the last few years I’ve settled down to one line of players. Why? Because I was happy to discover how well-designed and fun to use the underappreciated (and widely mocked) Zunes are.

  9. This is getting a bit more subjective, but I much prefer the Zune Marketplace. The interface is colorful, has more flair, and some cool features like ‘Mixview’ that let you quickly see related albums, songs, or other users related to what you’re listening to. Clicking on one of those will center on that item, and another set of “neighbors” will come into view, allowing you to navigate around exploring by similar artists, songs, or users. Speaking of users, the Zune “Social” is also great fun, letting you find others with shared tastes and becoming friends with them. You then can listen to a playlist created based on an amalgamation of what all your friends are listening to, which is also enjoyable. Those concerned with privacy will be relieved to know you can prevent the public from seeing your personal listening habits if you so choose.

  11. The Zune concentrates on being a Portable Media Player. Not a web browser. Not a game machine. Maybe in the future it’ll do even better in those areas, but for now it’s a fantastic way to organize and listen to your music and videos, and is without peer in that regard. The iPod’s strengths are its web browsing and apps. If those sound more compelling, perhaps it is your best choice.
