Promote recycling of aluminum cans

The aluminum can reproduces aluminum, consumes 71% less energy than extracting aluminum from bauxite, and reduces air pollution by 95%.

Many countries, especially developed countries, attach great importance to the recycling and utilization of used aluminum cans, and the recycling and reuse rate is also increasing.

The recycling rate of aluminum cans in the United States, for example, exceeded 50 percent as early as the 1980s and was 62.1 percent in 2000.

The recycling rate of Aluminum cans in Japan is also high, from 43% in 1990 to 83% in 2001.

At the same time, developed countries pay attention to classification in the recycling of waste aluminum materials. For example, the United States has classified different waste aluminum materials, sorted out and remelted the waste aluminum profiles and aluminum cans, and then made a little allocation to produce aluminum strips for aluminum profiles and cans, greatly reducing the cost.

According to statistics released by the Aluminium Industry Association in 2003, recycling rates in Brazil rose to 87% in 2002 from 85% the previous year, making it the world's largest recycler for two consecutive years.

In 2001, Brazil recycled 9 billion cans weighing 121,100 tons, or 47.8% of the country's reused aluminum, the association said.

In 2002, the can recycling industry had a turnover of 850 million reais ($270 million), of which 424 million reais ($130 million) was acquired.

Some 150,000 people in Brazil now depend on cans for a living.

Recycling cans can save a lot of electricity. Producing aluminum from waste aluminum USES only about 5 percent of the energy needed to extract it from ore. Recycling a can can save three hours of electricity for a 20-inch TV.

According to the Brazilian Aluminium Association, recycling cans saved 1705GW of electricity per hour in 2002, equivalent to 0.5% of the country's electricity consumption.

The recycling technology of discarded cans is weak in Our country and huge waste is formed accordingly.

This leads to a huge amount of foreign exchange for the cans in the disposable, immediately declared useless, causing a huge waste.

At the same time, the unrecyclable aluminum cans cause great pollution to the environment.

The market is calling for an economical alternative to aluminum cans.

At present, the international price of aluminum continues to rise, the production of aluminum cans in China has far exceeded the demand, China's 25 aluminum cans have been closed three enterprises.

And have experiment to prove at present, easy pull a can to be in processing process, once protective coating falls off, can cause can inner wall aluminium alloy and beverage to contact, as time passes, aluminium element melts gradually among them, contain to take acid or alkalescent drink to harm human body the biggest especially in the can.

In addition, aluminum cans pollute the environment, the state has issued a corresponding policy, clearly said that no new aluminum cans approved production lines.

In this case, steel cans and paper cans emerge as The Times require and become an alternative to aluminum cans.
