EWC 01 04 covers residues from beneficiation of non-metalliferous industrial minerals — kaolin, phosphate, potash, salt, sulphur, barite, gypsum and similar commodities. Processing routes include wet gravity separation, flotation, acid leaching and calcination, each generating distinct residue streams varying in physical form, chemical composition and regulatory classification.
Phosphate processing generates phosphogypsum (01 04 11) — a radiologically enhanced material due to naturally occurring uranium and radium co-precipitated from phosphate rock. Potash processing produces salt tailings (halite and clay fractions). Kaolin processing generates coarse sand reject and fine-fraction slurry. Hazardous sub-codes apply where processing reagents (acids, flotation chemicals) contaminate the residues above regulatory thresholds.
Reuse potential is significant: phosphogypsum is used in agriculture (soil amendment) and as cement retarder; salt tailings may be returned underground for backfill; kaolin rejects are used in brick-making. The EU Critical Raw Materials Act designates several non-metalliferous minerals (kaolin, phosphate) as strategic, incentivising recovery from processing residues.
Typical Generators
Established valorisation pathways for EWC 01 04 13, ranked by economic value and market depth.
Gravel, crushed rock and sand fractions (01 04 08, 01 04 10) tested per EN 13242 and reused as construction aggregate, road sub-base or drainage material. End-of-Waste status obtained via competent authority decision.
Phosphogypsum applied to agricultural soils as calcium and sulphur amendment. Salt tailings returned underground as backfill. Requires by-product status demonstration or national End-of-Waste criteria to exit waste regulation.
Residues not meeting by-product or EoW criteria managed in permitted extractive waste facility under Directive 2006/21/EC. Phosphogypsum stacks require radiological monitoring in addition to standard requirements.
These are the established routes for EWC 01 04 13. Which one your stream qualifies for depends on its composition, volume and region.
