The Valmet South America Pulp and Energy director, Fernando Scucuglia, celebrates the success in delivery schedule. “The evaporation and white liquor plants in Bracell’s line 2 will be the biggest plants of these technologies in operation in all over the world and the equipment installed call attention due their robustness and imposing. In addition, we will have the lime kilns fueled using biomass from the gasifiers. In other words, for the first time in South America, a plant of this size will not use fossil fuel, which makes us very proud as a company whose mission is to convert renewable resources into sustainable results”, explains Scucuglia. “The use of 'biogas' is a clean, economical solution that is connected to environmental ambitions of our customers and society. It works from the drying of biomass, gasification and burning in the lime kiln, including the controls, treatments and elimination of any gaseous pollutants”, adds the director.
