EffiSludge Closing Event 2021

The treatment of wastewater for industrial activities, such as pulp and paper production, is often highly energy intensive and alternatives are needed to achieve the reduction targets for fossil CO2-emissions. At the same time, sustainable wastewater management holds the potential for producing renewable fuels, such as biogas.

At the EffiSludge closing event – a one-day hybrid conference – more resource efficient concepts were presented and discussed, which combine e.g. industrial wastewater treatment with biogas production. The concepts should improve the carbon footprint of industrial wastewater treatment – through both energy savings and renewable fuel production.

The final results of the EffiSludge for LIFE Project were also presented and ways forward discussed.
