Did you know that paper mill sludge (PMS), one of the largest waste streams in the pulp and paper industry, can be transformed into valuable products? What’s often seen as waste, turns out to be a powerful source of innovation.
A new article in Renewable Energy, co-authored by Alucha, explores how fast pyrolysis can turn this waste into:
• A carbon-rich solid fraction
• Bio-based liquids
• Circular minerals like calcium carbonate
This opens the door to new ways of recovering energy and raw materials from industrial waste streams — making the paper industry more circular and sustainable.
The conclusion? PMS contains valuable minerals and biomass, that make it a promising feedstock for the circular bioeconomy.
This new research research supports the work we do at Alucha every day: recovering high-quality calcium carbonate from PMS and giving it new life.
