13 Jun 2024 --- Smurfit Kappa has invested in two “state-of-the-art” projects in Spain to enhance its sustainability profile. The first is a mass build-up of solar panels, and the second a landfill reduction project. The packaging supplier unveiled over 12,000 solar panels at its Sangüesa paper mill, which will work alongside its biomass and recovery boilers to generate more than 50% of its annual energy requirements, the “equivalent to powering 3,600 homes.”
