Get contacts for EWC 14 06 03*EWC 14 06 03* is a specific sub-code under EWC 07 07 — Wastes from manufacture, formulation, supply and use of fine chemicals and chemical products not otherwise specified. The classification guidance below applies to this waste stream.
EWC 07 07 is the catch-all for organic chemical process wastes not covered by 07 01 to 07 06 — it encompasses fine chemicals, specialty chemicals, flavours, fragrances, photographic chemicals (not 09 01), adhesive and resin intermediates, and chemical research by-products. Hazardous sub-codes parallel other 07 xx chapters: 07 07 01* (aqueous washing liquids), 07 07 03* (halogenated solvents), 07 07 07* (halogenated still bottoms), 07 07 08* (other still bottoms).
Fine chemical synthesis uses multi-step routes with multiple reagents, solvents and intermediate isolation steps — generating diverse, low-volume, highly contaminated waste streams. E-factors (waste kg per kg product) can reach 25–100, much higher than bulk chemical processes. Key challenges: complex mixed waste streams, small volumes that make dedicated recovery uneconomical, and highly variable composition requiring frequent waste characterisation.
Flavour and fragrance manufacture generates terpene-rich still bottoms (limonene, linalool), citrus extraction residues and essential oil decolouration carbon. These streams have potential as bio-based aromatic chemical feedstocks. CRO and toll synthesis facilities often operate across many different customer projects simultaneously, creating mixed waste classification challenges.
Typical Generators
Established valorisation pathways for EWC 14 06 03*, ranked by economic value and market depth.
Common solvents (ethanol, IPA, acetone, EtOAc, THF) from fine chemical synthesis separated by fractional distillation. Recovered solvents tested by GC purity analysis before reuse or sale. Third-party solvent recovery contractors accept mixed solvent streams for fractionation.
Non-halogenated still bottoms and mixed organic wastes with NCV >15 MJ/kg accepted by cement kilns or dedicated industrial energy-from-waste facilities. Waste characterisation analysis (GC/MS, metals, halogens) required before acceptance. Chlorine content limit typically 0.1–0.5% for cement kiln use.
Halogenated streams (07 07 03*, 07 07 07*) and wastes containing CMR substances incinerated at permitted high-temperature facilities. Small-volume drums from CRO/toll sites transported under ADR packing group requirements. Bulking of compatible streams reduces incineration cost.
These are the established routes for EWC 14 06 03*. Which one your stream qualifies for depends on its composition, volume and region.

US RCRA hazardous waste codes (40 CFR Part 261) that describe an overlapping or equivalent waste stream to EWC 14 06 03*.
F003 names nine specific non-halogenated solvents and their mixtures; EWC 14 06 03 covers any other non-halogenated solvent waste with no named-chemical restriction.
F005 names eight specific non-halogenated solvents from any generating industry; EWC 14 06 03 is the broader non-halogenated solvent waste code with no chemical list.
D001 is a pure flash-point characteristic applying to any waste; EWC 14 06 03 is scoped to waste organic solvents, which are commonly but not always ignitable.
U002 covers only unused, discarded acetone product; EWC 14 06 03 covers spent non-halogenated solvent waste from any process, used or not, not one named chemical.
