EWC 02 05 covers residues from dairy manufacturing: whey (liquid permeate from cheese-making), whey protein concentrate and lactose (both high-value by-products), effluent treatment sludge, off-specification products, CIP (clean-in-place) caustic and acid cleaning effluents, and milk rinse water. The EU dairy sector processes ~155 Mt of milk annually, generating significant co-product streams.
Whey — approximately 9 litres per kilogram of cheese produced — was historically a significant pollution problem (BOD ~60,000 mg/L). Today, ultrafiltration and nanofiltration membrane technology recovers whey protein concentrate (WPC) and isolate (WPI) as premium sports nutrition ingredients. Lactose permeate is crystallised to food-grade lactose or fermented to lactic acid or ethanol. Only residual whey that cannot be economically processed flows to biogas or WWTP.
Effluent treatment sludge from dairy plants is high in BOD, suspended solids and fat. DAF (dissolved air flotation) float from fat separation is rich in calories and increasingly co-digested with manure. The sector has achieved close to zero whey disposal in Northern Europe through integrated biorefinery approaches, but smaller artisan cheese producers still generate whey loads requiring wastewater treatment.
Typical Generators
Established valorisation pathways for EWC 02 05 01, ranked by economic value and market depth.
Liquid whey processed via ultrafiltration to WPC (35–80% protein) for food and nutrition market. Permeate crystallised to lactose or fermented to bioethanol. High-value by-product route removes whey from waste classification under Art. 5 Directive 2008/98/EC.
Whey permeate not meeting purity standards, DAF sludge and effluent treatment residues co-digested in biogas plant. High energy content (~4,500 kJ/kg COD) makes dairy waste a preferred co-substrate in farm and industrial biogas plants.
Off-specification liquid whey and dairy rinse water supplied to pig farmers as liquid feed under feed hygiene approval. Waste classification depends on intended use; directly contracted supply from factory to farm may qualify as by-product.
These are the established routes for EWC 02 05 01. Which one your stream qualifies for depends on its composition, volume and region.
