Alucha has developed a technology to treat industrial waste streams like paper mill sludge (PMS), sewage sludge and other industrial wastes. We can separate the inorganic and organic fractions of waste streams. From PMS we recover the filler content from the waste stream. This can save considerable amounts of CO2 equivalent compared to current disposal methods, and the process contributes to the circular economy too. With the process, the organic part of the waste stream (paper fibres) is converted mainly into bio-based oils. The inorganic part of the waste stream is separated and recovered as a product. The mineral recovered from paper mill sludge (Circular Calcium Carbonate, CCC) can be used again as a filler in various industries like plastics, paints & coatings, and rubber. The bio-based oils can be used as an energy source for the paper mill or possibly as a feedstock for bio-based chemicals.
