An integrated chemical pulp and paper mill : energy audit and perspectives on regional cooperation

• As a case study, an energy audit was performed at an integrated pulp and paper mill. A top-down approach was applied to identify and categorize the use of electricity, steam and hot water and the results of the audit are presented in this paper. Also, the connections and cooperation with both the nearby district heating system and a local steam deliverer, partly owned by the mill, are described. Potential ways to save energy are pointed out and changes in the cooperation are discussed. Moreover, a discussion of how the system can benefit from the taxation structure is presented, as the design of the studied system, in combination with the introduction of tradable green certificates, creates possibilities to exploit such benefits. As a result from this design it is shown that the introduction of these certificates promotes the use of oil to produce electricity.
