Customer Background
DS Smith is a leading British packaging and paper group, founded in the 1940s as a box-making business in East London. Today, it operates across more than 30 countries, employs approximately 30,000 people, and is celebrated as Europe’s largest cardboard and paper recycler. The company is deeply committed to a circular business model, emphasizing recycled content, sustainability, and innovation to eliminate waste.
At its mills in Rouen (France) and Dueñas (Spain)—both important hubs in DS Smith’s European network—separate innovations like Moisture Gates and NIR scanners have been deployed to ensure high-quality input materials and maintain the integrity of recycled paper in production.
“By improving measures of incoming Paper for Recycling our mills could see increased manufacturing yields. Not only this, but our transparent reporting system will provide clear communications to customers.”
Challenge: Measuring Moisture in Waste Paper Bales
DS Smith faced persistent challenges in accurately measuring moisture content in Paper for Recycling (PfR) arriving at its mills. Traditional methods—including moisture plates and oven testing—only sampled small portions of a load, leading to inconsistent and unreliable readings. This was especially problematic given seasonal moisture fluctuations, which could cause up to a 6% variation in paper yield between summer and winter.
Furthermore, suppliers expressed frustration over unverifiable results and outdated measurement methods. DS Smith’s ambition to maintain transparency and fairness in supplier dealings made it clear that a better solution was required.
Our Successes
Solution: Industrial Moisture Gate (IMG‑P)
Implementation of the Moisture Gate, developed collaboratively with Dunakontroll, transformed DS Smith’s moisture measurement process:
Automated scanning
All PfR-carrying trucks pass through the portal at 3–5 km/h, scanning about 75% of the load within just 30 seconds.
Full-load assessment
The system calculates the average moisture content for the entire truck in under a minute—without manual interference.
Seamless logistics
Trucks are not delayed; readings are recorded instantly and sent to suppliers, enabling transparent performance tracking.
