German scientists find that rotten fruit can be transformed into clean fuel

According to UPI reports, German scientists have discovered that decayed fruits can be used not only for composting as people have traditionally recognized, but also to become fuel and fuel.

Researchers at the Institute of Biotechnology, which studies the matter, have found a way to extract methane from expired rotten fruits that are discarded in vegetable wholesale markets, university cafeterias, and other places.

According to news released by the agency, the methane extracted from these decayed fruits through special fermentation can be compressed into high-pressure cylinders and used as fuel.

The researchers said that this year the institute will select a wholesale market in Stuttgart, Germany as a pilot. "Rotten fruit contains a lot of water and at the same time has a very low cellulose content, so it is very suitable for rapid fermentation."

1) the tensile, compressive and shear strength of Steel Structure is very high, and the section of steel structure is small and the weight is light. High strength of steel structure makes it suitable for the construction of large load bridges; light weight can reduce the base load, and the cost of the foundation, and also facilitate transportation and hoisting.

2) the ductility and toughness of steel is better and concrete, so that the seismic performance of Steel Structure Bridge is better. The seismic and wind resistance are the guarantee of bridge safety. The excellent seismic performance of the steel structure bridge extends its use range, especially in the high intensity seismic area.

3) reduced construction period. The material of steel structure can be rolled into many kinds of profiles, which is simple and rapid. The transportation volume of building materials is less, the construction area occupies a small area.

 4) the quality of steel bridge is easy to be guaranteed. Steel structural members are generally manufactured and processed in factories, with high degree of industrialization and high precision.

5) the steel structure is the environmental protection product. The old components removed from the steel bridge can be remelting, saving energy and consistent with the policy of sustainable development.
