Making the old new again
Remanufacturing is a tech upgrade.
Derrick Gaddis knew his equipment was nearing the end of its useful life. Two of his logging skidders — the heavy-duty machines that haul cut timber — needed to be replaced. But most manufacturers at the time had shifted gears to bigger and heavier models, he said, and no longer made the size of skidders required for what is known as selective harvesting, the type of logging his company does.
He and his co-owners of Henderson Timber Inc., in Sigel, Ill., devised a solution: What if John Deere, the original manufacturer, could remanufacture the skidder to repair and upgrade it, comporting with current technology? Deere, which already had remanufactured some of its products, was receptive. A beta test in the woods was in the works.
“When you take a puzzle apart with that many pieces, I thought there would be something wrong. But that was not the case,” said Mr. Gaddis, whose company is near the middle of the state, between St. Louis and Indianapolis, and who subsequently had a second skidder “relived,” as he called it.
Welcome to the expanding sector of remanufacturing. The practice essentially involves taking products or components, whether in disrepair or at the end of their useful lives, to a likenew condition. Accomplished through a variety of processes and advanced by new technologies like 3D printing, products as small as a coffee maker and as large as a medical imaging machine can now be upgraded. Rather than recycling or merely refurbishing the item to its original state, the process also enhances the product to make it comport with the latest technology.
While at first glance it seems similar to refurbishing, the results differ. A refurbished engine, for example, might be equivalent to one in excellent working condition but has already been in service for 30,000 miles, while a remanufactured engine should be equivalent to one that has not yet been in service, so it is like new, said Nabil Nasr, the director of the Golisano Institute for Sustainability at the Rochester
Institute of Technology.
While still a relatively small subset of manufacturing, its use is likely to grow as a result of recent technical advances like additive manufacturing, data analytics and the internet of things, also known as IoT. And it is an integral part of the circular economy that strives to keep materials in the economy and out of landfills.
“Remanufacturing is a smart way to continue to advance without creating a lot of waste. The development of new technology is allowing remanufacturing to grow stronger,” Dr. Nasr said. “Most of the emission and waste from manufacturing comes from material mining and processing.”
From an environmental standpoint, the process is superior to recycling, which captures materials, but loses the labor used in initial manufacturing and uses significant amounts of energy, Dr. Nasr said.
While remanufacturing does not have a glamorous connotation, companies involved are on the cutting edge of both manufacturing and data privacy.
Technology also creates new issues. The refrigerator with the touch screen that allows you to send notes home as well as order food? It can store personal data. That smart sous-vide machine that you got as a gift? It can access your devices for recipes. And the robotic vacuum cleaner that spares your back? It not only remembers furniture placement, but also uploads a map of your home to the cloud.
Presuming that data is removed from devices, remanufacturing is an important component of the circular economy. Original equipment manufacturers now realize that if they wait to think about a second life for a product or component until it is in disrepair or outdated, it could be too late.
A growing trend for companies is to plan for remanufacturing in the initial design of a product.
