Lecta Starts Up Biological Water Purification Plant at Zaragoza Pulp and Paper Mill

Lecta announced that it has successfully completed a new phase in its ambitious investment plan at its Zaragoza pulp and paper mill in northern Spain. This phase, totalling some 23 million euros, is focused on reducing the mills environmental impact.

Lecta’s goal is that the Zaragoza site become a benchmark for sustainability in the paper industry.

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.

Japan forum champions power of certification

Hosted in Tokyo on 24 June, the SGEC/PEFC Forest Certification Forum commemorated our 20th anniversary and celebrated the enduring role of forest certification in improving the social and environmental conditions of the world’s forests. The Sustainable Green Ecosystem Council (SGEC) is our PEFC national member for Japan. For Japan, as for the rest of the world, consumers and industry alike are increasingly demanding the materials they use and buy are certified as originating from sustainably managed forests. The country is therefore experiencing a rising interest and demand for the certification of its forests. “With the 2020 Tokyo Olympic and Paralympic Games approaching, the PEFC endorsement of the Japanese forest certification system means this, and other construction projects, can benefit from certified timber, provided locally through SGEC,” said Ben Gunneberg, PEFC International CEO.
