CO2 Emissions (t CO2/t)
The paper industry is one of the industries best positioned to mitigate climate change: the paper cycle begins with natural, renewable raw material (trees) that absorbs CO2 during its growth; stored carbon is not released when trees are cut but remains within the paper products themselves, true CO2 stores; paper can be recycled several times after use, thereby increasing carbon sequestration time; and even when it is not suitable for recycling, paper can be used as biofuel, as well as biomass, with the consequent reduction in landfill waste volumes and the resulting emissions.
All Lecta mills strictly monitor CO2 emissions and, since 2006, have reduced by more than 15% CO2 emissions per ton of paper as a result of a variety of energy-saving projects.
Energy consumption (MWh/t)
Efficient and sustainable energy use is a priority for Lecta, which has reduced specific energy consumption by 9% since 2006.
The implementation of a certified energy management system in accordance with the ISO 50001 standards in all of the Group's mills involves an exhaustive analysis of different points in the manufacturing process where energy can be saved and the implementation of measures to optimize energy consumption. These measures resulted in the installation of more efficient equipment, which, along with increased employee awareness, have allowed for reducing energy consumption to below 2.3 MWh per ton.
CHP (cogeneration) is an extremely efficient power generation system, given that it permits the simultaneous production of electricity and heat for industrial consumption, thereby saving primary energy and reducing greenhouse gas emissions while also increasing industrial competitiveness.
CHP also creates advantages for the community or territory where it is located, enhancing power supply and efficiency of energy transport while reducing its dependence on imported energy.
In order to improve energy efficiency and, consequently, reduce greenhouse gas emissions, Lecta's Zaragoza, Leitza, Motril, Sant Joan les Fonts, Condat and Cartiere del Garda mills have cogeneration plants, which consume natural gas, the cleanest and most efficient of the fossil fuels, one of which uses biomass as fuel, producing energy from renewable sources.
