Chi avrebbe mai immaginato di poter ricavare della plastica dalle banane? L'esperimento dei ricercatori dell' università di Belfast , nell'ambito del progetto Badana , è invece andato a buon fine, portando alla luce un prezioso metodo sostenibile : tale procedimento permette di evitare, nelle Isole Canarie, lo spreco di 25 mila tonnellate di banani che ogni anno vengono gettati.
Il progetto Badana, avviato nel luglio 2009 e della durata di due anni, ha ricevuto finanziamenti europei per 1 milione di euro : denaro che i ricercatori utilizzano al fine di mettere a punto nuove procedure per incorporare i sottoprodotti derivanti by banana plantations in the Canary Islands in the production of rotationally molded plastic with .
Bananas are a typical product of the Canary Islands, just think that "almost 20% of the bananas consumed in Europe come from the Canary Islands. Only on the island of Gran Canaria are growing every year about 10 million banana "says Mark Kearns, manager of the Polymer Processing Research Centre in Belfast.
" Once the fruits have been collected, the remainder of the plant ends up as waste ," he added, " and natural fibers contained in them could be used to produce rotationally molded plastic products for everyday items such as dolls, gas cans and cans for recycling "
" fibers of the banana tree will be processed and treated before being added to a mixture of plastic and sandwiched between two thick layers of pure plastics can guarantee excellent structural properties, "said Kearns contnuato.
Therefore, a new method, ecological and sustainable, a process that, first, should feed 's local economy, bringing benefits to companies that cultivate and sell bananas, and other environment-friendly, since it will be significantly reduced the amount of polyethylene used in rotational molding.
All papers in order to launch more environmentally-friendly era for the production of plastic!
