Axion International (OTCBB: AXIH), the developer of Recycled Structural Composite (RSC)? technology that is used to produce 100% recycled plastic ECOTRAX? railroad ties and STRUXURE? industrial building materials and Coll Materials are pleased to announce an increase in production capabilities. In June of 2011 Axion signed a contract manufacturing agreement with Coll Materials to expand the company's output and to do so at Coll's Southwest location in order to strategically service Axion's growing customer base.

Coll Materials is dedicating a second production line in their Waco, TX plant giving Coll the capacity to produce approximately 200,000 ECOTRAX? rail ties annually for Axion. The production line is on schedule and will be operational by Q2, 2012.

"Our rail business continues to grow across multiple customers around the globe, and this additional capacity is needed to meet growing demand," said Axion CEO and President, Steve Silverman. "Our relationship with Coll has grown since we first announced this partnership. Like any manufacturing start-up we've had our share of challenges and Coll has been a good partner and stepped up to make sure we met them head-on," Silverman continued. "As we grow we must remain quality oriented. Too many companies grow too fast and cannot put out a consistent product. We refuse to make that mistake. With this expansion we will be recycling up to 37 million pounds of waste plastic that would otherwise wind up in landfills."

"Contract manufacturing has been a great avenue to supplement our recycling business. We are pleased to be working with another green company and look forward to growing our capabilities to meet the demands that Axion's product brings," said Coll Materials CEO and President Brian Coll.

Axion ECOTRAX? ties are the prefect "green" solution for the rail industry - made using Axion's patented formula. The virtually indestructible ties thrive in extreme, wet, and caustic conditions.

About Coll Materials

Company CEO Brian Coll started Coll Materials in 2008 as a one man operation brokering plastic materials for plastic recyclers from his home office in Cambridge, OH. Six months later, the company had become profitable enough to take the next step from plastic brokering to a small plastic recycling operation. Coll Materials then leased a building in Byesville, OH to house two small plastic recycling lines and warehouse both raw and finished materials. In April of 2009 Coll Materials acquired another plastic recycling company, Regrind Services, a Detroit, MI based recycler serving the Midwest for over 14 years. In July of 2009, Coll Materials moved all equipment from the Midwest under one roof to Zanesville, OH. In 2011, Coll Materials acquired Nicos Polymers, establishing a plant in Allentown, PA and opened a new facility in Waco, TX.
