A breakthrough in recycling ash
After around 20 years of research, UPM has developed a new method for producing PCC (precipitated calcium carbonate) from ash, a by-product of our production process. This method is a huge step forward because it saves energy and makes use of ash that could otherwise go to landfill; as most of UPM’s waste material is comprised of ash from bioenergy production, this can have a massive impact on our overall sustainability. The PCC that is produced can be used as a paper filler material, which makes it useful for UPM Kymi’s production process.
