The EU collected 10.7 million tonnes of glass through municipal waste systems. Processing turned that volume into 5.4 million tonnes of cullet. Each ton recycled avoids 1.2 to 1.3 tons of CO2 equivalent compared with virgin production.
Key Takeaways
- In 2022, the EU recorded 128.8 million tonnes of municipal waste generated, representing a large addressable pool for glass diversion
- In 2022, total packaging waste in the EU was over 84 million tonnes (packaging waste totals used for material-specific recycling rates including glass)
- The EU glass packaging waste generated is tracked in tonnes per year, with the most recent complete series showing tens of millions of tonnes annually (glass packaging waste mass totals provided in Eurostat tables)
- A typical cullet addition level of 20% in glass batch can reduce melting temperature requirements by about 20–50°C (reported in glass recycling/materials engineering literature)
- Recycling one ton of glass can save about 1.2–1.3 tons of CO2e compared with making new glass from raw materials (life-cycle comparison commonly reported in environmental studies)
- Recycling glass is estimated to reduce energy consumption by about 10%–30% versus virgin glass production (range reported in engineering and sustainability reviews)
- Glass packaging is one of the main causes of 'high contamination' issues when mixed with ceramics and stones; a study quantifies that contamination can reduce recovered glass quality and increase sorting loss by measurable percentages
- Optical sorting systems used in glass beneficiation typically achieve glass recovery efficiencies in the 90% range when trained for cullet separation (quantified performance metrics reported in vendor/industry engineering papers)
- A study on glass cullet beneficiation reports that wet processing can reduce contaminants (ceramics/metals) to targeted levels with measurable removal efficiencies (quantified in study)
- Melting furnace studies show that replacing virgin batch with cullet can reduce melting temperatures by approximately 20°C per 10% cullet addition (quantified in materials processing literature)
- A lab study reports that for soda-lime glass, adding 50% cullet reduced viscosity and improved melting kinetics, measured as lower times to reach melt state (quantified kinetics results)
- In a published study of material recovery facility operations, rejecting contaminated glass fraction can increase residual disposal costs by a measurable percentage, motivating improved pre-sorting (quantified in analysis)
- 10,706,000 tonnes of 'Glass' municipal waste were collected in the EU in 2022 (collection by type), quantifying a direct material pool for cullet production.
- 5.4 million tonnes of 'Glass (cullet)' were produced from waste in the EU in 2022 (production output tracked in EU waste recycling accounts), representing recoverable glass material entering recycling systems.
- 74% of material recovered in EU waste treatment is from recycling/composting rather than other recovery routes, indicating that material-specific recycling (including glass) competes within a larger recovery framework.
EU glass recycling is scaling fast, cutting energy and CO2 while building a huge market-ready cullet supply.

01
Tomra's NIR sorting systems are specified to achieve up to 99% separation performance for certain material streams, which in practice supports high-purity cullet production when applied to glass beneficiation workflows.
02
The European Commission’s Joint Research Centre (JRC) documents that glass recycling typically requires collection, sorting, crushing and beneficiation steps before cullet can be used as a raw material substitute (process flow context backed by the JRC’s materials work).
Interpretation
Market & Technology Interpretation
From a Market and Technology perspective, advances like TOMRA’s NIR systems aiming for up to 99% separation performance are helping enable the high purity cullet outcomes that glass recycling still depends on, while the JRC notes that recycling must reliably go through collection, sorting, crushing and beneficiation before cullet can serve as a true raw material substitute.

World Business Council for Sustainable Development (WBCSD) and partners estimate that global demand for recycled glass is growing alongside broader circular-material mandates; the Global Cement and Concrete Association materials-to-circularity reports cite recycled feedstock expansion affecting glass cullet demand (policy-driven growth quantified in circular-economy market outlooks).
02
In the EU, the Packaging and Packaging Waste Regulation (PPWR) target is to reach 65% of packaging waste recycled by 2025 (targets include material-specific compliance pathways that drive investments in glass recycling systems).
Interpretation
Policy & Economics Interpretation
Policy momentum is making glass recycling more economically compelling as the EU’s PPWR pushes the recycling rate to 65% of packaging waste by 2025 and circular-economy mandates are expected to boost demand for recycled glass and cullet through expanded policy driven recycled feedstock use.
