Our range of high-quality, recycled glass materials serves the glass, insulation, and various other industries, offering sustainable and fully circular glass solutions.
Why choose Circular glass?
- Endlessly recyclable – Glass can be recycled indefinitely without losing quality
- High purity and quality – Our advanced sorting ensures premium raw materials
- Lower CO2-footprint – Reduce emissions by choosing circular materials
- Sustainable and cost-effective – Recycled glass conserves natural resources and cuts production costs
Premium circular glass for various applications

Hollow glass
High-purity recycled cullet (FRC- Furnace Ready Cullets) for new glass packaging and containers

Flat glass
Clean and refined cullets ideal for glass manufacturing and construction applications

Glass powder
Ultra-fine recycled glass particles for specialised industrial applications

PVB (Polyvinyl Butyral)
Recovered interlayer material for re-use in laminated glass and alternative markets

What happens to the glass from the bottle bank?
We take you behind the scenes of the recycling process for container glass. Discover how we effectively remove contamination and transform glass waste, raw glass cullets into circular products used in the glass industry.
The importance of flat glass recycling
Discover how we transform flat glass waste into pure cullets, forming the foundation for new glass products in the glass, insulation and various other industries.
