Smurfit Kappa Nervión S.A. – part of the Smurfit Kappa Group, specialised in paper-based packaging – has started up a 21.4 MW biomass-fired cogeneration plant at Nervión in Spain.

By adding 120,000 MWh to annual on-site generation, the new plant boosts the mill’s power capacity by 40%, enabling it to meet 65% of its power needs, said the firm.

Part of a €20m investment in power from biomass, the combined heat and power (CHP) plant has been enabled by earlier investment in a multi-functional crusher to process forest waste as well as a selection and storing system. Biomass consumption at the mill has risen by 40,000 tonnes to top 100,000 tonnes.

The biomass cogeneration plant project started in 2009 with an engineering study and equipment purchases.

Building got underway in January 2011 to complete a structure for the new 21.4 MW steam condensation turbine as well as four new refrigeration towers with a water circulation capacity of 2,500 m3/h in a continuous process.
