Green tissue production,

Meva Energy´s renewable gas producing plant will be replacing fossil gas consumption at Sofidel’s tissue mill in Kisa, Sweden. Switching to renewable Meva gas, it is estimated that the mill will reduce its CO2 emissions by 8,500 tons per year compared with the carbon footprint of today’s consumption of fossil LPG. By utilizing the generated biochar, a total of 10,300 tons of Co2 can be reduced. The fossil fuel free new plant is schedule to start up in the second quarter of 2023 with fuel locally produced out of wooden pellets.

Tissue for the future

The paper production is the fourth most energy intensive industry in Europe and accounts for 296 million tons of greenhouse gas emissions globally. Today, most tissue drying processes make use of directly fired natural gas or LPG in order to provide a hot flue gas stream which is blown through the drying hoods at the yankee cylinder in order to dry the paper. This combustion of fossil gas is today the main unsolved source of greenhouse gas emissions from the tissue industry.  By using Meva Energys unique gasification technology to convert low value biomass residues to renewable gas, the fossil gas can cost-efficient be replaced, also for high-quality applications such as in tissue drying hood.

Simple integration

No need for rebuilding of combustion chambers except changing to multifuel burners

Replacing fossil gas

Replacing fossil LPG for process heat generation to tissue drying through industrial burners.

High quality boichar

As a side-stream from the gasification process, biochar is generated. One of the many application areas for this is to use it as soil improvement. Hence, except a potential income source, a carbon removal effect could be added to the whole solution.

Renewable gas for tissue drying hoods

The existing drying system at Sofidel, including the combustion chambers will be kept, only the burners will be changed to multifuel burners to enable seamless switching between the existing gas solution to the lower calorific renewable syngas. Thereby, a full redundancy is enabled.   The continuous and stable character of the process ensures that the gas supply exhibits extremely small level of variation. The decentralized principle of on-site generation in combination with not having to refine the gas to pure methane is the basis for reaching a high conversion efficiency as well as realizing high levels of CO2 emission reductions. Based on this, the Meva Energy technology can realize more substantial cuts of CO2 emissions than conventional types of biofuel.

Europe’s second largest producer of tissue paper

Sofidel, Europe’s second largest producer of tissue paper in terms of capacity with 35 production plants is making an significant investment towards their carbon 2030 footprint reduction goals. The development of the pioneering technology has been supported by studies carried out by Sofidel Corporate Technical Dept based in Lucca and ANDRITZ Novimpianti along with the Dept of Energy of University of Pisa (UniPi) related to utilizing low-calorific renewable gas for tissue drying.

Kisa, Sweden 

Customer challenge

Replacing their fossil LPG

Solution

Due to stability of the Meva Energy gas composition and very small variations of gas flow and pressure it is possible to replace existing fossil gases also in sensitive industrial processes, like drying of tissue paper at Sofidels mill in Kisa.
