Bulleh Shah Packaging decided in 2011 to examine alternative energy sources for its paper mill at Kasur in Punjab. The existing boilers generated process steam and electricity for the mill with the aid of natural gas and heavy fuel oil.
COWI produced a conceptual design and a ‘bankable feasibility study’, and the conclusion was that a new biomass boiler facility should be established alongside the existing plant.
This solution would provide a more reliable energy source and reduce operating costs by using waste biomass from locally grown crops as fuel.
It was decided to establish a new 40 MWe biomass-fired boiler and a new flue gas scrubbing system with bag filters. Existing turbines, cooling system and electrical systems were re-used wherever possible.
