17 National statistics Total amount of wood waste ton Papper mills: wood waste and sludges make up to ton per year. Statistics are depending on whether wood is considered waste or byproduct. Hazardous wood waste: ton, but since crushed, impregnated wood will be calculated twice both as a primary waste and a secondary after crushing, the total actual number is lower.
