Stanley-Santos cropGlobally, the pulp and paper (P&P) industry is the fifth largest industrial source of CO2 emissions. Recently, the Paris Agreement has hjosirljosirted the target of achieving below 1.5oC temperature rise. In order to achieve this goal, bio-CCS has an important role to play to achieve this target.

In a pulp mill, the CO2 emissions arise mainly from its recovery boiler, multi-fuel boiler and lime kiln. The majority of this CO2 originates from the combustion of biomass, which renders it as carbon neutral if the biomass used as raw materials of the pulp production is grown and harvested in a sustainable manner. If the CO2 emission from pulp and paper industry is captured and permanently stored, then this could be considered as a potential carbon sink. As such, the pulp and paper industry could be regarded as an industry with potential for the early demonstration of both bio-CCS and industrial CCS.

This study provides an assessment of the performance and costs of retrofitting CCS in a Nordic Kraft Pulp Mill (Base Case 1A) and an Integrated Pulp and Board Mill (Base Case 1B). Different configurations of capturing CO2 (90%) from the flue gases of the recovery boiler, multi-fuel boiler and lime kiln were examined.
