OCC is delivered to our paper mills, where it is transformed into coreboard. During this process OCC is thoroughly cleaned, removing impurities such as plastics and metals. We use the OCC to produce coreboard, which is delivered to our manufacturing sites, making Sonoco Alcore an integrated core manufacturer. Depending on the type and quality of the core, we use a variety of board grades.
At our Karhula paper mill, plastic impurities are removed and transferred to a local biomass power plant, where they are used to create energy.
Wastewater is delivered to a local water treatment plant, where it is treated and ready to return to its source, the Kymi River.
