National statistics Total amount of wood waste 1 200 000 ton Papper mills: wood waste and sludges make up to 135 000 ton per year. Statistics are depending on whether wood is considered waste or byproduct. Hazardous wood waste: 170 000 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. Non-hazardous wood waste from households 410000 ton. Wood waste to composting 26 000 ton Non hazardous Wood waste to Waste to energy: 1 600 000 ton Haz wood waste to Waste to Energy 98 000 ton Impregnated wood waste from building and demolition: 50 000 ton Non-haz wood waste from building and demolition 200 000 ton Wood waste to Waste to Energy: 250000 ton 2017-10-17
