“…The energy potential of optimisations in the vacuum system is considered to be large, but unfortunately this aspect has not gained too much attention in many paper mills (Paulapuro 2000). A considerable energy saving potential in this section could further be found in overdimensioned pumps and compressors (Wikström et al 2007;Möllersten et al 2003). Ranges in specific steam use (0.0-1.1 GJ/t paper) are somewhat smaller than ranges in specific electricity use and could be explained by, e.g.…”

There are large differences between paper mills in, e.g. feedstock use and grades produced, but typical processes are similar in all mills. The aim of this study is to benchmark the specific energy consumption (SEC) of similar processes within different paper mills in order to identify energy improvement potentials at process level. We have defined improvement potentials as measures that can be taken at mill/ process level under assumed fixed inputs and outputs. We were able to use industrial data on detailed process level, and we conducted energy benchmarking comparisons in 23 Dutch paper mills. We calculated average SECs per process step for different paper grades, and we were able to identify ranges in SECs between mills producing the same grade. We found significant opportunities for energy efficiency improvement in the wire and press section as well as in the drying section. The total energy improvement potential based on identified best practices in these sections was estimated at 5.4 PJ (or 15 % of the total primary energy use in the selected mills). Energy use in the other processes was found to be too dependent on quality and product specifications to be able to quantify improvement potentials. Our results emphasise that even a benchmark on detailed process level does not lead to clear estimations of energy improvement potentials without accounting for structural effects and without having a decent understanding of the process.

“…In a Swedish case study of a chemical mill it is stated that it is not unlikely that these energy efficiency potential is valid for the studied mill (Klugman et al, 2007). Furthermore, other research indicates, at least technically, that potential also exists for further significant energy efficiency improvements in other areas, for example process heat integration (pinch) analysis (Wising et al, 2005;Bengtsson et al, 2001;Andersson et al, 2006;Holmberg & Gustavsson, 2007;Möllersten et al, 2003;STFI, 2003,).…”

“…Gross consumption of paper and paper board, for example, increased from 35.75 million tons in 2000 to 110.11 million tons in 2011, with an average annual growth rate of 6.1% (Zhang et al 2012;NBS 2012). More recently, a greater number of studies highlighted energy consumption and greenhouse gas (GHG) emissions from the pulp and paper sector at global or national levels because of increasing concern on climate change (Zhang et al 2012;Szabóa et al 2009;Möllersten et al 2003;Kallio et al 2004;Davidsdottir and Ruth 2004).…”

Background: Labeling of carbon foot-prints (CFPs) for products and services is regarded as a convenient and effective method for reducing greenhouse gas (GHG) emissions. Life cycle analysis (LCA) is a useful tool for examine CFP of relevant products and services. However, the corresponding standards for CFP of products and services can hardly be satisfactorily adopted. Also, most of the previous studies were based on an individual indicator, which can hardly reflect multiple dimensions of sustainable implications of products and services. Results: Thus, in this research, a hybrid life cycle analysis (LCA) and multi-criteria decision analysis (MCDA) method
