At the moment, the rechargeable batteries we rely on in our gadgets don’t contain the most environmentally-friendly materials, and aren’t the type of thing anyone should be throwing away. They should be recycled at a specialist recycle center.What would be much more eco-friendly is a way to create power from waste products, but at a level where an individual could do it themselves. Sony has been working to create these so-called bio-batteries, and has just shown one off at the Eco-Products 2011 environmental products fair in Tokyo.Sony’s idea is to provide a battery where by the user adds their own fuel sourced from waste materials. In this case, the proof of concept battery uses a mixture of enzymes to break down shredded pieces of paper. The paper provides the cellulose that is broken down by a first set of enzymes to produce sugar, the second set of enzymes then uses the sugar to produce hydrogen ions and electrons. Finally, the electrons are used to produce electricity through a circuit, while the hydrogen ions form water by being exposed to oxygen in the air.If such a battery were to go commercial, it could see certain waste products such as paper reused to power batteries rather than being recycled outside of the home. In order for that to happen, the battery technology has to produce enough power to make it viable. At the moment, that’s the sticking point, and something Sony has already spent several years trying to improve. It seems at best the bio-battery will power a digital music player.This isn’t the first time we’ve seen a bio-battery in action. Early last year Sony demonstrated a fan being powered by a sugar-filled soft drink. We’ve also see a cell phone modified to run purely on Coca Cola.Read more at Yahoo! News

The disease, which is extremely contagious and has devastated banana industries around the world, affects the roots of banana plants and eventually causes the plants to die.It is understood that ICA is preparing a statement on the matter. Two Colombian banana farms are under quarantine due to their suspected infection with Fusarium Wilt Tropical Race 4 (TR4), FreshFruitPortal.com understands, although there has been no official confirmation by Colombian authorities.In two resolutions that have since been deleted on the website of the Colombian Agricultural Institute (ICA), single-line preview statements said that two farms have been quarantined “due to the presence of symptoms associated with [TR4]”. The full resolutions can no longer be accessed on the website.The farms – Don Marce and Eva Norte – are located in the northern department of La Guajira, close to the border with Venezuela.ICA representatives contacted by FreshFruitPortal.com were unable to speak about the matter, but a source in the Colombian banana industry said that tests were currently being carried out to establish whether or not the plantations are infected with TR4.Ecuadorian news website Expreso [in Spanish] claims that it has been able to access the now-unavailable documents, which it says provide information on the situation, including wide-ranging measures to prevent the disease from spreading.
