Stiles Machinery donated more than 160 multifunctional bookcases to Habitat for Humanity at the conclusion of IWF 2012.

The “Tetris” bookcases — named because of their resemblance to the Tetris computer game — were created during four daily machine demonstrations through four days of the fair.

“Stiles strives to be a conscientious, green-thinking company.” Stiles vice president of marketing and communications Steve Waltman said in a statement. “We look for ways that we can be more resourceful and apply the green practices of reduce, reuse, and recycle.

“A lot of suppliers demonstrate their equipment at the fair, and then scrap the product at the end of the show. By donating to Habitat for Humanity, we were able to eliminate waste and give back to the community.”

Roücke Pressing Technologies, Boise Cascade, Hettich and Rehau partnered with Stiles in the creation of the Tetris book cases by donating material and hardware.
