When packaging giant DS Smith decided to build a new factory in Värnamo (Sweden), to replace two old ones, their priorities were clear: Reduce energy costs, which mainly resulted from fans used for waste extraction, and improve the working environment. The task was given to Swedish company Presona, which has extensive experience and expertise in this field.
Old solution: costly and dusty
The factory produces corrugated cardboard packaging, and when the die-cutting machines cut the cardboard to create boxes and other types of packaging, excess cardboard, known as trim, is generated and must be handled.
“In the old factory in Värnamo, we had an air extraction system with many energy-demanding fans and shredders to remove the trim. It was also constructed in a way that created a lot of dust,” says site manager Zelko Balinovic.
“Presona delivered the absolute best solution for our specific needs,” adds Zelko Balinovic.
Furthermore, multiple shredders were needed to break down large discarded sheets of cardboard before they could even be fed into the air extraction system. The shredders were noisy and dusty.
