Project's context and challenges

VPK Group produces sustainable packaging such as recycled paper, corrugated packaging, solid board packaging and cores and edge protectors. VPK Group was an existing customer of Econvert with reactors being installed at their joint-venture location Blue Paper in Strasbourg and the VPK Oudegem and Alizay sites. All Econvert reactors at the other VPK sites were performing as promised, and thus Econvert was contacted to implement anaerobic wastewater treatment combined with biogas desulfurization and biogas utilization at the VPK Corex Board Soustre site.

"Since 2020, Econvert has been our trusted partner in anaerobic treatment for VPK group. During the last 5 years, Econvert has successfully implemented anaerobic treatment solutions at our recycled paper production sites Oudegem, Strassbourg, Alizay and Soustre even if it was not always a walk in the park. At all four locations, Econvert’s reactors perform as promised. We recommend Econvert as both a technology provider and reliable partner for anaerobic treatment. "

Customer benefits

Econvert-EGSB® designed to handle recycled paper effluent challenges (calcium and high loads)

>99% H2S removal efficiency of Econvert-Dsulph®

Produce up to 600 m3 biogas per day

Small footprint

Proven references in this application

Econvert-EGSB® is easy adaptable in height in order to meet height restrictions

Solution

Econvert designed, engineered and delivered an Econvert-EGSB®. To remove H2S and re-use the produced biogas in the existing steam boiler, an Econvert-Dsulph® and a complete biogas line were installed. All equipment, internals and tanks were supplied by Econvert. By installing a state-of-the-art anaerobic treatment plant VPK reduces energy consumption and operational costs while improving effluent treatment.
