Sheet paper has varying attributes like its size (we use millimeter in Europe), material content and weight (gramme). „A” sizes are common, „B” sizes are used by printing presses while „C” sizes are envelope sizes.
|„A” size||„B” size||„C” size|
|A0||841 x 1189||B0||1000 x 1414||C0||917 x 1297|
|A1||594 x 841||B1||707 x 1000||C1||648 x 917|
|A2||420 x 594||B2||500 x 707||C2||458 x 648|
|A3||297 x 420||B3||353 x 500||C3||324 x 458|
|A4||210 x 297||B4||250 x 353||C4||229 x 324|

After chopping wood is graded. Logs are then sawed into planks and the rest is grinded for cellulose (glue). Adding water and other substrates to the mix and grinding it throughoutly will smoothen the final product’s surface. They press and dry the mix to get a fine roll of paper which then gets cut into sheet paper.
Recycling is another matter. The method is similar to normal paper making but the pollutant is not the bark but the ink, graphit and any other colorant. After grinding they use an inert materialt trying to purify the paper mass. Adding glue and continous pressing would result in a much more polluted material which has many inconveniences compared to pure paper. Still they are whitish and printable.
