Alcoa and Exal Combine Efforts to Promote Water Purification System New Technology to Be Unveiled at G-20 Summit

September 21, 2009

PITTSBURGH & YOUNGSTOWN, Ohio–Alcoa (NYSE: AA), the world leader in the production and management of
primary aluminum, and Exal Corporation, the world’s leading manufacturer
of specialized aluminum packaging, have joined together to help promote
newly developed water purification technology set to be introduced prior
to the G-20 Summit. The event will be held at the Carnegie Science
Center starting at 12:00 noon on Wednesday, September 23.

With aluminum supplied by Alcoa, Exal utilized its revolutionary
Coil-To-Can (C2C) aluminum container technology to create a promotional
bottle for Pittsburgh-based Project Eviive. During the meeting of world
leaders, the non-profit group will use the aluminum bottle to help
unveil a system that it believes will alleviate the world’s growing
fresh water crisis. The water purification technology, developed by
Epiphany Solar Water Systems, utilizes solar energy to distill unclean
water in a way that is simple, inexpensive, and sustainable.

Project Eviive called on Alcoa and Exal to create an aluminum container
that would not only be impactful, but would help convey its mission.
Because of its lower impact on the environment and high degree of
sustainability, Exal’s C2C technology was the perfect choice for the
project. C2C is an innovative hybridized technology that marries the
manufacturing speed and light weighting of standard (drawn & ironed)
beverage can technology with the dynamic shaping technology originally
available only with heavier walled extruded aluminum containers. Because
of their lighter weight, containers made via C2C use less fossil fuel
throughout the logistics chain, producing fewer transport-related carbon
dioxide emissions than heavier packaging formats. Exal’s C2C process
also utilizes post-consumer recycled aluminum as a raw material and
finished C2C containers are infinitely recyclable. Because the C2C
process incorporates high-speed production lines less energy usage per
container is required.
