[Son] "Where do inner tubes go after they die mamma?"

[Mom] "They end up at Green Guru of Boulder where they are turned back into useful products again."

From the Daily Camera

Lewis, 33, is the president and founder of Green Guru Gear, a Boulder-based repurposing company launched two years ago that converts unusable wetsuits, inner tubes, climbing ropes and banners into bike gear and accessories.

"One of the challenges in product design, manufacturing and sourcing is ... you're always looking for suitable material," said Lewis, a cyclist and outdoors enthusiast with a background in product design. "I used to work at bike shops growing up, and I got tired of throwing away the tubes and tried to reuse them."

In 2009, Green Guru Gear was developed as a subsidiary of Denver-based Ecologic Designs Inc., an "upcycling" manufacturing business Lewis founded in 2007. Ecologic repurposes damaged or excess goods into products such as beverage cozies, bracelets and key chains, all aimed at the broader eco-conscious clientele.
