EWC 03 03 covers the diverse waste and by-product streams from pulp manufacturing and paper/board production: fibre-rich rejects (primary sludge, screen rejects, broke), biological treatment sludge (biosludge), causticising residues (green liquor dregs, lime mud/grits), ash from bark boilers and recovery furnaces, and de-inking sludge from recovered paper processing. The EU pulp and paper sector processes ~90 Mt of fibre annually, making this a significant industrial waste category.
Primary fibre sludge (fine fibres, fines, fillers) is the largest stream by mass in integrated mills. It can be dewatered and used in board production, composted or burned. Biosludge from activated sludge treatment of mill effluent has lower calorific value but is typically co-fired with bark in the mill's power boiler. De-inking sludge from recovered paper mills contains ink particles, fillers and short fibres — its management is a major operational cost, typically composted, landfilled or used as soil amendment. Dregs and grits from lime cycle operations are typically landfilled or used in construction.
Integrated kraft pulp mills are largely energy self-sufficient through recovery furnace combustion of black liquor and bark, but generate causticising waste (dregs, grits) requiring dedicated disposal routes. The IED BAT Reference Document for pulp and paper defines BAT-associated emission levels and waste minimisation techniques. Increasing fibre recovery from de-inking sludge and ash-to-cement routes are active areas of industrial symbiosis development.
Typical Generators
Established valorisation pathways for EWC 03 03 10, ranked by economic value and market depth.
Bark, biosludge, primary sludge and rejects dewatered and co-fired in mill power boiler or recovery furnace. Generates steam and power for on-site use. BAT for kraft mills includes maximising internal energy recovery before export of residues.
Fibre rejects to board and packaging manufacturers; primary sludge to composting; ash to cement kilns as raw material substitute; dregs to road construction aggregate. Requires testing and product quality agreements with receivers.
Dregs, grits and de-inking sludge not meeting product quality specifications for reuse disposed at permitted non-hazardous landfill. Leachate from high-pH causticising waste (dregs) may require pre-treatment before landfill acceptance.
These are the established routes for EWC 03 03 10. Which one your stream qualifies for depends on its composition, volume and region.

Primary generator; fibre rejects recycled into lower-grade paper and board grades
Cement kilns use paper ash as raw material (silica/alumina) and primary sludge as fuel substitute
Composting and biogas facilities process de-inking sludge and biosludge
Dregs and grits used as construction fill or aggregate where chemistry permits
