Data description

Questionnaire, definitions, allocation of inputs and outputs to different paper products produced in the same mill.

The questionnaires are available through the two Associations as a supplement to this report. A list of definitions is included in this report. The questionnaires were updated and harmonized for primary fibre based mills and recycled fibre based mills. The questionnaire included a mass balance for recovered paper mills, energy balance, water balance and carbon balance.

The questionnaire treats the paper mills and corrugated board plants as a black box, asking for annual inputs to and outputs from the mill or plant.

Differentiation between the processes within the site, such as power generation, pulping, paper production, wastewater treatment, has not been made.

In case the mill produces other products (e.g. market pulp, sold energy), the mills reported only the inputs and outputs that were allocated to paper production.

No allocation was made to by-products, so the reported inputs and outputs include the production of these by-products.

For those paper mills producing more than one grade of paper it is necessary to allocate inputs and outputs to the different paper grades. Mill people who filled in the questionnaire have done the allocation according to causality.

Example:
For a mill producing both Semichemical Fluting and Kraftliner the total input of wood to the mill site has been reported as well as a percentage allocation figure indicating how much of the total wood consumption should be allocated to Semichemical Fluting and how much to Kraftliner.
