Plans for a 25 MWe biomass combined heat and power (CHP) plant at paper mill are poised for approval by Aberdeen City Council in Scotland.

The on-site CHP plant would supply the Arjowiggins site at Stoneywood, running on locally sourced low-grade wood unsuited for sawmills or timber production.

As well as meeting 90% of the mill’s process heat, in the form of hot water and steam, the cogeneration plant would feed excess electricity to the grid.

A meeting of the council’s Development Management Sub-committee is due to consider a planning application on 17 January. But a report to the committee has already praised the project for cutting carbon emissions and using wood that currently has no market.

Estover Energy, which is developing the project, describes the Scottish town of Aberdeen as one of the UK’s most heavily forested areas, with about 6.5% of the nation’s forest cover within 60 miles of the plant.

Under-harvesting is a major issue for Scotland’s forestry, according to Estover Energy. By increasing demand for low-grade wood, projects such as the biomass can help tackle this issue.

The Stoneywood site has housed a paper mills since 1770. Arjowiggins currently produces papers including the famous Conqueror brand here.
