New York university technology: using waste aluminum and seawater to reduce carbon dioxide in the air
A team of researchers at york university has developed a novel technical solution.
The team used water and aluminum waste from whitby, north Yorkshire, to reduce excess carbon dioxide in the air.
The technology could help reduce greenhouse gases that cause global warming by 850m tonnes.
In the process of technology research and development, the researchers first to aluminum reactor filled with water and waste, and carbon dioxide through the water inside the reactor, then make derived from solar power electric current through the reactor, thus activated aluminum scrap, make them react with carbon dioxide from the dissolved in the water of the sea, to generate sodium diaspore materials.
Unlike conventional co2 treatments, the technology does not require hydrogen participation, so the solution is cheaper.
Michael, a professor of chemistry at the university of york, said: "now, every year there are tens of millions of tons of waste aluminum is not recycled, why not use them to improve our environment?
In this technique, scrap iron can also be used instead of aluminium.
Also, a lot of scrap iron is produced every year.
Aluminum and iron is one of the most abundant element in the earth's crust, we developed the technology is mainly use the two kinds of metal materials as raw materials, makes our technology more sustainable."
Currently, researchers are working to improve the energy efficiency of the aluminum-based carbon dioxide clean technology.
Their goal is to build a comprehensive production system after the technology is adopted.
