Integrated Paper Services Inc. recently became the fourth lab to earn approval from the Corrugated Packaging Alliance, certifying its ability to perform the testing protocol for repulping and recycling corrugated cardboard.
The Appleton, Wis., company is known as IPC and provides independent testing for the paper and pulp industries, according to its website. With the OK from the Corrugated Packaging Alliance, IPC is approved to perform the testing protocol outlined in the voluntary Standard for Repulping and Recycling Corrugated Fiberboard.
The protocol is used to verify that wax alternatives used on corrugated cardboard are acceptable for repulping and recycling, according to a news release from the alliance. As of July, 38 wax alternatives had gained certification and been registered with the Fibre Box Association.
Dwight Schmidt, president of the Fibre Box Association and executive director of the Corrugated Packaging Alliance, said in the news release the number of wax alternatives is growing dramatically, citing a study that showed a 30% increase in them in 2010.
The other three labs OK’d by the alliance are: North Carolina State University, Department of Wood & Paper Science, Raleigh; Western Michigan University Pilot Plant, Kalamazoo; and Centre Specialise en Pates et Papiers in Trois-Rivieres, Quebec.
