Remanufacturing - A Key Strategy in The Circular Economy
In 2019, we will use 1,7 times more from nature than our planet can renew in a year. Resources are used faster and faster and we generate too much waste, every year billions of tonnes are buried in landfills. SKF remanufacturing helps reduce waste by restoring used products to new condition. In this article we learn more how this contributes to the circular economy.
Remanufacturing is one of the key strategies for achieving a circular economy, to reduce, reuse and recycle material. At SKF we provide remanufacturing for a range of products to various industries, for example Railway, Metals, Mining, Pulp & Paper and Wind among many others.
One essential benefit of remanufacturing is that already processed material (in products) is used for longer time. A bearing normally replaced after three years, could be remanufactured twice and last up to nine years, providing the function three new bearings would.
Another benefit is that high-quality steel is kept in the recycling loop. As of today, almost all high-quality steel (e.g. cars and machine equipment) is recycled as low-quality construction steel (e.g. concrete reinforcement bars). Within the scope of remanufacturing, if we at SKF find that a bearing cannot be remanufactured, it can instead be recycled as high-quality steel, for example as input to make new bearings.
A scenario with no remanufacturing compared to one where the bearing is remanufactured twice. That means instead of buying three bearings you only need one which is remanufactured twice. In this example up to two-thirds of the material (bearings) is saved over time. The arrows illustrate the material flow and the thickness the amount. If we at SKF find that the bearing cannot be remanufactured, it can be sent to high-quality recycling.
Producing a new bearing requires that raw material goes through many processes like heat treatment and machining. These processes generate waste (removal of material and scrap), use energy and different indirect materials, for example process fluids. All of this have an impact on the environment. With remanufacturing a lot of this is avoided as much fewer processes are needed compared to producing a new bearing.
