This past July, LC Paper inaugurated a biomass boiler that allows the company to manufacture tissue products with neutral CO2 emissions. This boiler was the last step of a challenge that began more than a decade ago, when the company rethought all elements of the production process with the aim of being able to manufacture paper without emitting carbon dioxide. Achieving “zero emissions” is an important milestone, resulting from the aims to reduce energy, water and raw material consumption.
In traditional tissue paper processes, manufacturing one tonne of paper consumes around 3,000 kWh. By re-engineering the manufacturing process, LC Paper has reached a final consumption of only 1,100 kWh per tonne–a decrease in energy consumption by two thirds.
Following its constant innovation process, LC Paper’s switch from a gas boiler to a new industrial biomass boiler with a steam generation capacity of 4,000 kg per hour, allows for the production of more than 50,000 tonnes of European eco-label certified and carbon neutral paper.
This will halt the consumption of 2,930 kW of natural gas –a substantial saving –while consuming 1.26 tonnes per hour of PEFC certified wood chips from forest near the factory. A zero value is imputed in the emission of carbon dioxide CO2 because the gas that is released in the combustion is the same one that the plant has taken in its process of photosynthesis. Forestal Soliva, founded in 1946, will be in charge of supplying the approximately 8,000 tonnes per year of “biomass kilometer zero”.
On this occasion, Inypsa Eficiencia acts as an energy services company within the project; proving steam (4tn/hr) to the three papermaking lines of the plant. In addition to using clean energy for the environment, it will provide 10% savings on primary energy consumption. For Inypsa Eficiencia, which currently operates 12 energy service contracts, this project represents a pioneering entry into the industrial sector, a strategically important area.
All this way has allowed LC Paper to lower manufacturing costs and increase the value of paper made with a powerful message of sustainability. For them, today a new task begins: to look for those markets where sustainability is a rising value, markets such as France, Germany, Holland, Belgium, Denmark, Scandinavia, Australia and New Zealand. Recently, LC Paper has innovated in the field of sustainability, creating a new manufacturing technology called OnePly, which has participated in the Horizon 2020 program of the European Union. OnePly products have physical characteristics similar to conventional tissue paper, although they require significantly lower amounts of energy and raw material, allowing the company to remain a leader in the field of sustainability.
This is the twelfth biomass industrial plant completed by Imartec Energía in the last 5 years; if in doubt, a reference project, an unique project.
