Glass manufacturing generates waste glass (cullet), refractory waste, batch dust and off-gas treatment residues as primary waste streams. In-house cullet from glass furnace operations is remelted directly as the highest-priority recovery route, typically comprising 20–30% of furnace batch in primary production. Every 10% increase in cullet use reduces furnace energy consumption by approximately 2.5% and CO₂ emissions proportionally.
Refractory waste from glass tank furnace rebuilds arises every 5–12 years per furnace. Silica and alumina refractories from the melting zone contain residual glass and chromium oxide from checker brickwork, potentially requiring hazardous waste classification. Furnace dust collected in bag filters contains fine glass, batch carryover and volatilised lead, arsenic and barium from specialty glass formulations.
Specialty glass production (optical, borosilicate, lead crystal, CRT) generates waste streams with specific regulatory requirements. Lead crystal cullet containing >24% PbO requires management as hazardous waste. CRT glass contains lead in the panel and cone glass (up to 25% PbO in cone) and barium in panel glass; processing requires licensed e-waste facility. Commission Regulation 1179/2012 establishes end-of-waste criteria for cullet (excluding CRT and lead glass).
Typical Generators
Established valorisation pathways for EWC 10 11 10, ranked by economic value and market depth.
Clean cullet from production defects is returned to furnace batch as direct energy-saving raw material substitution. Colour-sorted container glass cullet from MRF sorting is sold to container glass furnaces. Flat glass cullet returned to float glass furnace if within composition specifications.
Mixed or contaminated cullet not suitable for furnace remelting is used as road sub-base aggregate (glasphalt), filtration media for water treatment, sandblasting media and drainage aggregate. Ground glass powder is used as pozzolanic cement replacement or filler in plastics and rubber.
Lead glass (CRT cone, lead crystal) is processed by specialist licensed operators using hydrometallurgical lead recovery or direct remelt for lead alloy production. Refractory containing chromium(VI) from checker brickwork is disposed to hazardous landfill after testing.
These are the established routes for EWC 10 11 10. Which one your stream qualifies for depends on its composition, volume and region.

Remelt clean float glass cullet in furnace batch to reduce energy and raw material costs
Use colour-sorted container glass cullet as principal furnace batch component
Use crushed glass as supplementary cementitious material or fine aggregate in concrete
Process CRT and lead crystal glass waste for lead recovery at licensed WEEE facility
