Following the installation of two new electrostatic precipitators in the mill's recovery boilers, resulting in a 74% reduction in solid particle emissions, Lecta has started up a biological water purification plant with excellent results. In the first few months, there has already been a drastic reduction in effluent load, with values far below the legal limits. Chemical Oxygen Demand (COD) values were cut nearly in half, Total Suspended Solids (TSS) have decreased by 36% and in the case of Biochemical Oxygen Demand (BOD5), the decrease was even more pronounced — 72% compared to the average observed in 2013.
Zaragoza is Lecta's only integrated mill, manufacturing both pulp and paper with a total production capacity of 500,000 tons of pulp, coated paper, uncoated paper and base paper for specialty products.
