When Capacity, Quality, and Continuity All Matter
Norsk Gjenvinning processes over two million tonnes of waste annually and plays a key role in supplying secondary raw materials for energy production and manufacturing.
Their existing waste wood shredding line could no longer keep pace with demand — but replacing it was not a straightforward equipment swap.
Key challenges included:
-
Inconsistent output quality due to oversized fractions and excessive fines
-
Requirement to meet ISO P63 chip size standards batch after batch
-
Installation inside a fully operational facility, directly next to the old line
-
Zero tolerance for extended downtime or production losses
The task was not just to increase capacity, but to stabilise output quality and protect downstream value.
