E 'is unique in the world. Maintained by technical graduates, separating the materials with the force of the water and turns them into energy and fertilizers.

Without ... recycling, ie the separation of the various components such as plastic, glass, "wet" and so on, the garbage can not be disposed of, burned, recycled. It's the dogma. But is it true? The Israelis say no. And to prove it. They have set up a short distance from Tel Aviv a mega facility which receives 800 trucks every day from 2700 tonnes of rubbish (to say. The: ability to transform and dispose of all waste in Campania accumlati so far), and ensuring the separation of materials they contain, recycles and enhances everything - plastics, glass, wood, metal, wet - and obtaining fertilizer, natural gas, biogas, electricity. Thanks to the spirit of initiative and Appeal innovation and advanced technology, the Israelis are in fact managed to turn rubbish into a treasure, a true source of wealth.
Quite the opposite of what is happening in Naples and Campania, where for months and months (years) the garbage is a drama without a solution. The mayor of Naples, Rosa Russo Jervolino and the governor of Campania, Antonio Bassolino would therefore do well to make a good tourist trip to Israel. Should head for the accuracy, Hiriya, a village in the plain of the river Aylon, near Ben Gurion airport in Tel Aviv and the region that includes 17 other municipalities with a total of about three million population. There, there is a dump of Gush Dan, the largest in the country, a veritable mountain of garbage which covers an area of \u200b\u200bmore than 450 thousand square meters and more than 60 meters high.
Opened in 1952, this landfill has been active for nearly half a century amassing 16 million cubic meters of garbage. Then, in 1998, was closed. Some time later the authorities in the region have decided to turn it into a large public park, the Ayalon Park, pledging to achieve the target by 2020.
One could not but build a large garden on the waste, leaving them as they were. It was so elaborate a plan for treating and recycling the extract of some interest. Relying on technology, so the Israelis have set up at the foot of the mountain of garbage a range of processing equipment.
"The planned disposal". Marco Cattaneo says that he went to Hiriya on behalf of the magazine "Le Scienze", "started in 2000 and now trucks ply between the waste mountain and the various facilities where they are just unloaded 2,700 tons of material per day.
main biological treatment plant, managed by the Environmental Public Service Company (ESC), the garbage is discharged into a gigantic bathtub full of water where light materials that float, such as plastic, paper and cardboard, glass bottles or bulbs, are
separate from heavy, such as metals, which are deposited on the bottom, and are recovered for recycling. After removal of inorganic, organic waste remain in the water. Everything at this point, passes through a number of other pools, where shall filters to separate the biological material from the water. n the first is used as fertilizer, while the water, now purified, partially revert in the first tank to begin a new cycle and is partly intended to irrigate the land.
There is a gas plant, consisting essentially of a silo where the garbage is heated to 800 degrees, producing syngas, some of which is used to power the system, and the remainder is intended to generate electricity electricity. While you're setting up a facility for the treatment of tires, are a plant for the wetlands consist of five large pools in which aquatic plants like water lilies and papyrus are responsible for purifying waste water, absorbing the organic material with their roots. "
But it is not over. In addition to a facility which receives and separates materials such as bricks, tiles, timber, there are finally scattered throughout the area, 63 wells where the biogas produced is collected by the buried materials, producing 4 megawatts of power going to fuel a ' textile company, a few miles away. "
The Israelis, in fact, have succeeded in transforming a mountain of rubbish - we repeat, undifferentiated - in a small gold mine in a few years that will become the largest public park in the country.
The secret of this amazing feat? The spirit of initiative and the use of innovative technology, even avant-garde. No coincidence that the 100 employees of the ESC, which is still the company's municipal rubbish collection, 30 are university graduates and 42 graduates. It is no coincidence that Israel is the first country in the world to invest in research, with 4.8 percent of GDP, of which 3.25 percent by enterprises.
final point: Australians are copied to the Israelis, setting up a system similar to that of Hiriya in their country. When will the Campania?
