Progroup AG is a family-owned containerboard and corrugated sheetboard producer headquartered in Landau in der Pfalz, Germany.

Alongside its three paper mills and 14 sheetfeeder plants in six countries, the group runs two refuse-derived fuel (RDF) combined heat and power plants that supply steam and electricity to its paper machines: a 525,600 t/a plant in Eisenhüttenstadt, in operation since 2011, and a 440,000 t/a plant in Sandersdorf-Brehna that entered commercial operation in mid-2025. The group is now preparing a further recovered-paper mill at the former Sappi site in Stockstadt, where a third waste-to-energy plant may follow.

Key Takeaways

• Progroup AG is a privately held stock corporation founded in 1991 as Prowell GmbH by Jürgen Heindl in Offenbach an der Queich. The group office is in Landau in der Pfalz.
• The founding Heindl family controls the company through JH Holding GmbH. Maximilian Heindl has been CEO since January 2023 and his brother Vinzenz Heindl joined the board as Chief Sales Officer in 2025.
• Two RDF-fired fluidised bed CHP plants serve the paper mills: Progroup Power 1 GmbH in Eisenhüttenstadt (525,600 t/a, 150 MW thermal, commissioned 2011, bought from energy supplier EnBW at the end of 2015) covers the full steam demand of paper machine PM2. Progroup Power 2 GmbH in Sandersdorf-Brehna (440,000 t/a, 105 MW thermal) does the same for PM3.
• The Sandersdorf-Brehna plant (PPO2) was built from March 2023 with a Valmet bubbling fluidised bed boiler and has supplied PM3 with steam and power since mid-2025. A sludge pipeline and the routing of PM3 rejects to PPO2 are scheduled for completion by the end of 2027.
• Growth projects include a new containerboard mill at Stockstadt, where Progroup took over the Sappi site in May 2024 and plans a machine by the end of the decade, and packaging-park partnerships with Akarton in Schüttorf (March 2026) and Zeus Packaging in Ellesmere Port (August 2026).
