This sub-chapter is a residual category for oil wastes not classified under 13 01 (hydraulic oils), 13 02 (engine and gear oils), 13 03 (insulating oils), 13 04 (bilge oils), 13 05 (separator contents) or 13 07 (liquid fuels). It captures quenching oils, rolling mill emulsions, drawing oils, wire rope lubricants, metalworking fluid concentrates and mixed oil waste streams from industrial operations.
Quenching oils used in metal heat treatment are particularly significant: used quench oil contains oxidation products, metal particles and water emulsified at elevated temperature. Quench oil service life is typically 2–5 years before viscosity increase, acidity and particle contamination necessitate complete replacement. Used quench oil with flash point >60°C is non-ignitable during normal handling but classified hazardous due to petroleum hydrocarbon content.
Rolling mill emulsions from steel and aluminium cold rolling contain mineral oil at 2–5% in water with emulsifiers, biocides and corrosion inhibitors. Rolling mill emulsion waste is generated when biocide resistance develops, tramp oil contamination rises or product quality requirements change. Emulsion volumes range from 100,000 to 500,000 litres per mill change, making disposal logistics complex.
Typical Generators
Established valorisation pathways for EWC 13 02 05, ranked by economic value and market depth.
Quench oils with stable composition and low contamination are re-refined or reconditioned by vacuum distillation, filtration and inhibitor addition for reuse in heat treatment. Rolling mill emulsions are broken by acid dosing, oil phase recovered and sent to re-refinery, water phase treated biologically before discharge under trade effluent consent.
High-calorific oil wastes (>28 MJ/kg) not suitable for re-refining are accepted by cement kilns as alternative fuels after analysis for chlorine, sulphur, metals and calorific value. Rolling mill emulsions with <5% oil content are typically not suitable for cement kiln co-processing due to low calorific value; high-oil emulsion concentrates are acceptable.
Mixed or heavily contaminated oil wastes not meeting re-refinery or cement kiln acceptance criteria are incinerated in licensed hazardous waste incinerators with energy recovery. Full characterisation including PCB screening required before acceptance. Incineration certificate returned to waste producer as evidence of final disposal.
These are the established routes for EWC 13 02 05. Which one your stream qualifies for depends on its composition, volume and region.
