Baling Underfoot

Carpet padding, also known as carpet cushion, represents one of our nation’s most efficient closed-loop recycling efforts. The formal name for recycled carpet padding is bonded polyurethane foam, or re-bond carpet padding.

You can’t mistake it. It’s the multi-colored padding made up of chopped and shredded pieces—pieces of used carpet padding combined with postindustrial polyurethane foam scrap.

According to the Carpet Cushion Council, Riverside, Conn., recycled carpet padding now accounts for 80 percent of all carpet padding sold in the United States. Remarkably, more than 50 percent of all used and removed carpet padding in the United States is recycled and used to make new re-bond carpet padding, as reported by the National Association of Home Builders Research Center.

This level of recycling is approaching the phenomenal success of asphalt and concrete recycling, or certainly the aluminum can recycling rate in the United States. According to the Aluminum Association, Americans recycle between 53 percent and 54 percent of all aluminum beverage cans shipped.

COMBINED EFFORT. The national estimate of recycled, post-consumer carpet padding scrap amounts to 62,500 tons per year. That’s enough used carpet padding to create a 50-foot wide roll stretching from Los Angeles to New York City (or enough to cover almost 12,000 football fields)—a significant amount of material that could otherwise be landfilled.

Producing recycled carpet padding involves the efforts of a number of industries and businesses working together, including carpeting and padding installers, retailers, materials brokers, padding manufacturers and padding recycling companies. Approximately 200 carpet padding recycling companies are in the United States. These companies collect, bale and ship used carpet padding to more than 30 U.S. factories where it is converted into new re-bond carpet padding.

One of these padding recycling companies is run by Mike Trick, president of Cushion Recyclers, with locations in Louisville and Lexington, Ky., and Kennesaw, Ga. Trick also operates a wholesale flooring accessories company. "Much of the used carpet padding we receive is brought directly to one of our locations from carpet installers and contractors within a 20 to 25 mile radius," Trick explains. "Individuals weigh their scrap padding using a truck, pallet or conveyor scale and are paid between 5 and 10 cents per pound.

"We also receive used padding from collection bins located at retail carpeting and flooring accessories stores throughout our operating regions," Trick states. "While installers and contractors are not paid for the used padding they drop off, the bins do provide a convenient disposal site for them as they stop to pick up carpeting and flooring supplies."

"The stores also benefit from our bin system," Trick adds. "The collection bins not only offer their installer and contractor customers a convenient disposal site for used padding, they serve the same purpose for the store’s installation teams. We send our trucks out to replace full bins with empty bins, and in this instance, the store locations receive the 5 to 10 cents per pound paid for used padding. Plus, the stores save the time, transport costs and tipping fees they would typically incur in disposing the used padding at a landfill."

Once Cushion Recyclers receives the used carpet padding, it is bundled or baled and then transported to either a broker or directly to the closest carpet padding manufacturer. At the manufacturer, it undergoes a series of steps in a recycling process to create totally new re-bond carpet padding.

The recycled, or re-bond carpet padding, is formed by combining chopped and shredded pieces of used carpet padding with postindustrial polyurethane foam scrap in different sizes and usually different colors into one solid piece. The process starts with grinding, steaming and chemically washing the padding. The sterilized padding is mixed with postindustrial polyurethane foam scrap (with virgin foam in some instances) and molded into padding rolls of various fractional-inch thicknesses. Sources of post-industrial foam scrap include manufacturers of sofas, chairs, mattresses, automotive seat padding and door panels, textiles and clothing.

COMPRESSION REQUIRED. Trick says operational efficiency is critically important for carpet padding recyclers to maintain profit levels. "Bundling and baling in preparing the used padding to ship may be the most important step to maximize your operating efficiency and ROI," he says.
