The two different water contents are interchangeable: MCG (%) = (MCD / (100 + MCD)) x 100 MCD (%) = (MCG / (100 – MCG)) x 100 Additionally, the dry material content (DCG) of fresh wood can be calculated as follows: DCG (%) = (100 – ((mass of water in wood) / (wet mass of wood))) x 100 Dryness values, which are more or less theoretical for fresh wood, in parenthesis |

1) Dryness 90%. 2) Source: Indufor 2013. 3) For reasons of consistency, the Indufor (2013) figure of 143 million RWEs is used. By using a conversion factor of 3.97, the figure would be 145.3 million RWEs. According to CEPI (2011), the amount of pulpwood consumed in the CEPI region is 147 million RWEs. However, the pulpwood consumption statistics for CEPI are based on a different country structure and a different definition of imported pulpwood. The value of the conversion factor changes annually depending on the volume shares of different imported wood pulps. 4) Europe is a net importer of wood pulp. A difference of 30 million RWEs (difference between wood pulp consumption and production) is consumed in wood pulp source countries. 5) Weighted average, which takes into account the consumption volumes of different wood pulps. Instead of 3.97 a rounded figure 4.0 is used in calculations. |

For example, the European recovered paper collection was 56.2 million tons in 2010. This volume consists of 38.3 million tons of (dry) fiber, 12.3 million tons of non-fiber components, and 5.6 million tons of water. |
