Get contacts for EWC 10 13 09*EWC 10 13 09* is a specific sub-code under EWC 10 13 — Wastes from manufacture of cement, lime and plaster and articles and products made from them. The classification guidance below applies to this waste stream.
EWC 10 13 covers solid residues arising during the manufacture of cement, lime and plaster, including cement kiln dust (CKD), lime kiln dust (LKD), concrete and pre-cast rejects, and uncured mortar. These streams arise at multiple kiln points: cyclone pre-heater, calciner, and electrostatic precipitator, each with different alkali content and mineralogy.
Cement kiln dust (CKD) contains significant lime (CaO), calcium carbonate and alkali sulphates. When the alkali bypass is limited, CKD can be recycled directly into the kiln feed. Excess CKD is marketed for soil stabilisation (NACE 42.11), agricultural pH correction, and as a partial cement substitute in lower-strength applications. Cembureau reports that EU cement plants achieve >85% valorisation of CKD through kiln recirculation or external sale.
Pre-cast concrete rejects and wash-water sludges from concrete plants are EWC 10 13 17 or 10 13 06 respectively. These are increasingly processed through concrete wash-water recycling systems (NACE 23.61) that separate aggregate (reused as secondary aggregate) and cement paste (returned to mixer or used in low-grade fill). Zero-reject concrete plants now operate across the Netherlands, Germany and Belgium.
Typical Generators
Established valorisation pathways for EWC 10 13 09*, ranked by economic value and market depth.
Cement kiln dust (CKD) with alkali below kiln-feed limits is directly re-injected at the kiln inlet, displacing raw material inputs. Modern ILC (in-line calciner) kilns achieve 100% CKD recirculation for low-alkali dust fractions. No external licensing required for on-site recirculation.
High-free-lime CKD and lime kiln dust (LKD) are applied to weak subgrade soils for civil engineering ground improvement under BRE Digest 427. Agricultural application corrects pH of acid soils (lime equivalent value 40–70 CaO%). Both routes require nutrient and heavy metal analysis under the Soil Conditioner Directive.
Cement kilns (1,450°C, 6+ second residence time) are the leading platform for alternative fuel co-processing under EU IED Annex VI. CKD from co-processing kilns may contain elevated heavy metals requiring bypass control before external valorisation of the dust fraction.
These are the established routes for EWC 10 13 09*. Which one your stream qualifies for depends on its composition, volume and region.
