Glass is 100% and endlessly recyclable, but recycling it to the quality melting plants require demands clean cullet, free of impurities. A glass crushing and sorting machine solves this requirement in a single flow: it crushes the glass into controlled-size cullet and automatically separates impurities, metal, labels, caps, plastic, producing clean cullet ready for remelting at glass plants.
A glass crushing and sorting machine is the choice of glass recyclers, collection centers and operators who process used glass packaging and want to produce quality cullet, sellable at good prices to glassworks. See the full range of recycling equipment and the solutions for glass recycling.
• Crushing and sorting in one flow, a glass crushing and sorting machine combines crushing with impurity separation, eliminating manual sorting.
• Controlled-size cullet, crushing produces cullet calibrated for remelting.
• Metal separation, magnetic and eddy current separators extract iron and aluminum (caps, closures).
• Light material separation, labels, plastic and paper are separated from the cullet.
• Clean cullet for remelting, clean cullet sells to glassworks at good prices.
• Reduced contaminants, clean remelted glass produces quality products, free of impurity-related defects.
• Automatic control, continuous flow with monitoring and dust capture.
• Scalable, capacity is sized to the volume of glass processed.

A glass crushing and sorting machine serves glass recyclers, glass packaging collection centers, municipal waste management operators and plants that produce cullet for glassworks. Collected glass invariably contains impurities, metal caps, labels, closures, plastic residues, which must be removed to produce quality cullet, acceptable to glassworks for remelting.
Glass waste management is regulated at European level within the circular economy framework; a glass crushing and sorting machine delivered in Europe is designed in line with the requirements of Directive 2008/98/EC on waste. For integration into a complete glass recycling flow, see also the complete industry solutions.
The quality of the cullet produced by a glass crushing and sorting machine determines its market value and acceptability at glassworks: cullet with metal or ceramic impurities causes serious defects in remelted glass, which is why glassworks demand clean cullet with minimal contaminant content. Automatic separation of impurities produces quality cullet, sellable at good prices.
Metal separation is essential in a glass crushing and sorting machine: metal caps, closures and rings from jars and bottles contain iron and aluminum, which must be completely removed from the cullet. The magnetic separator extracts iron and the eddy current separator extracts aluminum, ensuring cullet free of metal contamination, essential for defect-free remelting.
The environmental benefit of recycling glass with a glass crushing and sorting machine is significant: remelting cullet consumes less energy than producing glass from virgin raw materials (sand, soda ash, limestone), and every ton of cullet used reduces raw material consumption and the associated emissions. Since glass is endlessly recyclable without loss of quality, recycling it is a perfect model of the circular economy.
The economics of glass recycling with a glass crushing and sorting machine are attractive: collected glass has a low cost (or is a waste to be managed), while clean cullet has market value at glassworks. Turning collected glass with impurities into clean, sellable cullet, plus the reduction in disposal costs, makes the investment profitable for operators with steady glass volumes.

1. Used glass is fed into the crusher.
2. The crusher crushes the glass into controlled-size cullet.
3. The magnetic separator extracts iron (caps, metal rings).
4. The eddy current separator extracts aluminum (closures, caps).
5. The light material separation system extracts labels, plastic, paper.
6. The clean cullet is collected; dust is captured by the filtration system.
The PLC system coordinates the flow and flags anomalies. A properly adjusted glass crushing and sorting machine produces clean cullet of consistent quality, ready for remelting, maximizing the value recovered from collected glass.
What impurities does a glass crushing and sorting machine separate?
It separates metals (iron by magnetic separation, aluminum by eddy current), light materials (labels, plastic, paper) and, in advanced stages, sorts the glass by color. The result is clean cullet, free of metal or organic contaminants, acceptable to glassworks for defect-free remelting.
Why does cullet cleanliness matter?
Cullet with metal or ceramic impurities causes serious defects in remelted glass. Glassworks demand clean cullet with minimal contaminant content. A glass crushing and sorting machine produces quality cullet, sellable at good prices, unlike collected glass with impurities, which has low value.
Can it process flat glass (window panes)?
Yes, flat glass without a laminated layer can be processed by a glass crushing and sorting machine. Laminated panes (with a PVB layer) require a special laminated glass separator. Plain flat glass is crushed and cleaned like any glass, producing cullet for remelting.
Is the delivered equipment new?
Yes. We deliver new, unused equipment, built to order, not reconditioned units. The build uses components from established suppliers, CE marked where applicable, and every machine undergoes a full inspection before shipment. You receive the technical documentation and operating manuals in your language.
What makes URSTAG a premium brand?
European design, top-tier components and experience. Every machine is designed by our engineering teams in Europe and built from components by industry leaders such as Siemens, Schneider Electric, ABB, WEG, SEW-Eurodrive, NORD Drivesystems and Bonfiglioli. The result is reliable, energy-efficient and durable equipment, backed by over 15 years of experience and by delivery, installation, training and service included.
How long do installation and commissioning take?
Transport, commissioning and operator training are included and carried out by a local team, in your language. Before shipment, the machine undergoes a full inspection, so your unit becomes operational quickly, with no hidden installation costs.
What size is the cullet produced?
The size of the cullet is controlled by adjusting the crusher and the screens. Glassworks have specific particle-size requirements for cullet; a glass crushing and sorting machine is adjusted to produce the required size. The optimal size is set according to the cullet buyer's requirements.

Six technology directions we integrate turnkey: from plug & play IIoT sensors, to cobots, predictive maintenance, optical inspection, MES connectivity and custom industrial software.
See in real time how much each machine produces and how long it sits idle. We fit sensors on any equipment, new or old, and within a few hours you have the OEE dashboard on your phone. No complex wiring, no production downtime. The first concrete step toward digitalization, with ROI visible from the very first month.
Solve your labor shortage without tripling your costs. The cobot works safely alongside your people (palletizing, feeding the CNC, welding) while you recover the investment in 12-18 months. Prices 30-40% below European distributors, with installation and programming included from us.
Stop waiting for things to break. Our algorithms analyze sensor data and tell you exactly which part will fail and when, and we bring it to your production line before the breakdown. Zero unplanned downtime, zero contractual penalties, complete operational peace of mind.
Eliminate defects before they reach the customer. Our cameras inspect every part at speeds no operator can match, detecting sub-millimeter defects. They mount onto your existing line, with no modifications. Ideal if you produce for export and have strict quality clauses.
Connect your machines to your office, regardless of brand or age. Our gateway automatically translates the data from any machine into your ERP's format: no manual entry, no paper forms, no human error. The manager sees production live, the operator receives digital instructions.
Have a process that no off-the-shelf software can solve? We build custom industrial applications: from tailored SCADA panels and HMI interfaces, to production planning systems, lot traceability and automated reporting.
