SWG collaboration: Today’s economic pathway to net-zero alumina
Edited by : AL Circle x GEA

Sahl Regen, Worley and GEA (SWG) have collaborated to demonstrate how integrating Sahl Regen’s KX Heat Exchanger with GEA’s Mechanical Vapour Recompression (MVR) evaporation can reduce Bayer-process energy consumption by around 70 per cent. The collaboration is reinforced by Sahl Regen’s Kassofor Programme, which advances Net-Zero goals through verified carbon capture in regenerated soils.
Key highlights of the article
- 70 per cent total energy reduction of the Bayer process and full digestion electrification with KX + MVR.
- All KX components are individually proven, with the first integrated demonstration unit ready to build.
- Reuse of Bayer-contaminated waters and environmental compatibility of MVR condensate.
- Measured and independently verified carbon offset credits: Integration of the Kassofor Programme as a complementary Sahl Regen initiative, providing ISO-verified Article 6.2 carbon offsets with extensive social and environmental co-benefits. Making CO₂ a problem solver, not the problem.
- Solution for the whole aluminium industry: Final framing that the KX and Kassofor solutions enable Net Zero not only for alumina but for the aluminium industry as a whole.
