around 16 per cent of the costs of paper production go towards energy, with heat and steam required for the pulping process

he pulp and paper sector is renowned for being energy-intensive, constituting seven
With energy prices on the rise, paper mill owners and operators need to find increasingly innovative ways to reduce costs without impacting performance. Nigel Thompson* identifies combined heat and power technology as a potential solution
accounting for a large proportion of this figure (ref 2). Despite this, more than 80 per cent of energy consumed by the European paper industry comes from natural gas and biomass sources, rather than bought-in electricity (ref 3). This high and consistent level of heat and power demand
means that paper mills and manufacturers are ideally placed to benefit from CHP technology. The Confederation of European Paper Industries (CEPI) shares this conclusion, identifying CHP as the best energy technology available and expecting mills to adopt it where possible (ref 4).
What is CHP? CHP, sometimes known as cogeneration, involves generating electricity while capturing the huge amounts of heat otherwise wasted in conventional power plants.
Using this recovered heat, CHP plants can reach efficiencies
