Valmet has been selected by Sappi Southern Africa to deliver a full EPC (Engineering, Procurement and Construction) package for the replacement of recovery boiler components at the Saiccor Mill in South Africa. This upgrade of critical boiler parts will improve operational safety, reduce the risk of unplanned downtime and improve overall reliability of the mill.

“The project will address key operational challenges by restoring the structural integrity and thermal performance of critical boiler components. This upgrade is an important step in maintaining reliable and safe operations at the Saiccor Mill. Valmet’s in-depth knowledge of our site and proven experience in complex shutdown projects support the successful execution of this work,” says Jan Burger, Engineering Manager, at Sappi Saiccor.

“Valmet’s lifecycle approach supports customers throughout the entire lifetime of their assets — from early project phases to operation, maintenance, upgrades, and long-term performance improvement. Our long-standing relationship with Sappi and extensive experience in executing shutdown projects at the Saiccor Mill give us strong site-specific knowledge that enables accurate planning and efficient execution during critical outages. Combined with skilled teams and specialized tools, this ensures safe and reliable pressure part replacement and further demonstrates Valmet’s role as a trusted partner for recovery boiler and energy solutions in the pulp and paper industry,” says Amit Roy, Senior Sales Manager, Pulp, Energy and Circularity Services at Valmet.

The order was included in Valmet’s orders received for the first quarter of 2026. The value of the order is not disclosed. The delivery and installation work will take place during the major outage in February 2027.
