Get contacts for EWC 07 01 04EWC 07 01 04 is a specific sub-code under EWC 13 07 — Wastes of liquid fuels. The classification guidance below applies to this waste stream.
Wastes of liquid fuels include off-specification diesel, heavy fuel oil tank bottoms, fuel contaminated with water or microbial growth, and fuel storage tank cleaning residues. EU fuel distribution infrastructure generates waste fuel through product quality failures, tank water accumulation, pipeline cleanouts and terminal decommissioning. Off-spec road diesel failing EN 590 specification for FAME content, cetane number or flash point is managed as waste fuel rather than returned to specification.
Fuel storage tank bottoms are a particularly significant waste stream: diesel storage tanks accumulate water, rust particles, wax and microbial biomass (particularly the diesel bug fungus Hormoconis resinae) as sediment. Tank cleaning generates several tonnes of sludge per tank containing 30–60% fuel value hydrocarbons combined with corrosion products and microbiological material. Flash point testing determines transport classification.
Aviation fuel waste arises from fuel quality management at airports: overwing fuel contaminated with jet fuel service equipment, filter/separator change waste and emergency fuel drain operations. Aviation turbine kerosene (ATK) off-spec waste has high calorific value (43 MJ/kg) and low sulphur content making it attractive for cement kiln co-processing or blending into marine fuel oil bunkers where permitted.
Typical Generators
Established valorisation pathways for EWC 07 01 04, ranked by economic value and market depth.
Off-specification diesel failing only one parameter is blended with in-specification fuel at fuel terminals to meet EN 590 specification, avoiding waste classification entirely. Slightly water-contaminated fuel is water-separated by centrifuge and flash-point verified before return to product. Blending operations require licensed fuel terminal facility.
High-calorific waste liquid fuel (>30 MJ/kg) is co-processed in cement kilns under alternative fuel protocols. Fuel analysis including flash point, chlorine, sulphur, metals and calorific value required before acceptance. Cement kiln destroys all organic compounds; mineral content absorbed into clinker. Preferred route for high-value fuel waste maintaining energy recovery.
Heavily contaminated fuel tank bottoms or biologically degraded fuel not meeting cement kiln or blending acceptance criteria are incinerated in licensed hazardous waste incinerators with energy recovery. Full fuel characterisation required. Liquids with flash point <60°C may require dedicated liquid waste incineration chamber.
These are the established routes for EWC 07 01 04. Which one your stream qualifies for depends on its composition, volume and region.

F005 is a fixed list of solvents from any industry; EWC 07 01 04 scopes to spent organic solvents and washing liquids arising specifically from organic chemical process operations.
U002 is the unused commercial acetone chemical being discarded; EWC 07 01 04 covers spent organic solvents from organic chemical process operations, not unused product.
