Alcoa Ecoclean panels help fight smog

The world’s leading producer of aluminum, Alcoa, has just introduced a new building technology that could change the face of architecture throughout the world. The new coil-coated panel, called Reynobond with EcoClean, is designed to be self-cleaning, in that it aids in the decomposition of smog and other pollutants that cling to building surfaces.

According to an Alcoa press release, 10,000 square feet of Reynobond with EcoClean has the equivalent air cleansing power of about 80 trees which can offset the smog created by the pollution output of four cars every day.

“Alcoa is committed to innovating sustainable solutions for today and tomorrow,” said Craig Belnap, president of Alcoa Architectural Products, in a press release. “That passion is a driving force behind our architectural business. Our R&D in science and technology is creating new ways for aluminum building products to meet green building standards—from the use of natural cleaning products like Reynobond with EcoClean, to advanced façade solutions that help reduce CO2 emissions and energy consumption.”

Reynobond with EcoClean was created by combining breakthroughs in science and design from Alcoa and the Japanese manufacturer TOTO. The pre-painted aluminum panel, Reynobond, is coated in a titanium dioxide coating, called EcoClean. When put out in the sun, the panel acts as a catalyst to break down pollutants, like smog, on its surface and the air around it, into harmless matter that can be washed away by rain.

These panels not only helps keep the environment clean, but also allows building owners to save on maintenance costs by ensuring that the building will remain clean with little to no outside work. The panel’s coating is superhydrophilic, meaning that the surface becomes super slick when it comes into contact with water.

Rainwater, therefore, won’t bead on the surface, but instead flow down the building, taking with it all of the broken-down organic matter from the surface. According the Alcoa’s website, even the smallest amount of rain or humidity can trigger this effect, meaning that the building is almost constantly being washed.

Alcoa’s website has a video which demonstrates exactly how Reynobond with EcoClean works. It also has an environmental calculator that takes the square footage of a building and tells you how Reynobond with EcoClean would affect the environment around it if installed.

The units it uses for this are the amount of trees that would be equivalent to how much cleaning your building would do, and the smog created by a number of cars per day that your building would offset. It also includes the potential maintenance costs that would be saved when using Reynobond with EcoClean.
