Glass Recycling
Glass recycling demands exceptional purity to meet stringent manufacturing standards. Even minor metallic contamination, such as bottle caps, aluminium seals, wire reinforcement, or steel fixtures, can compromise furnace operations, damage equipment, and lead to defective glass products.
BlakerTech’s dry separation solutions deliver the performance required for this demanding application. The MagThro™ Eddy Current Separator is engineered to remove non-ferrous metals from flat glass, hollow glass and laminated glass streams, using its high-intensity neodymium magnetic rotor for accurate separation and high recovery. This ensures the cleanliness levels demanded by glass manufacturers are achieved, while also maximising material recovery and processing efficiency.

Glass Recycling Applications
-
Understanding Glass Recycling Challenges
-
In glass recycling, even minor metal contamination can have significant consequences. Ferrous metals can damage furnace machinery and introduce defects into manufactured glass, while non-ferrous metals such as aluminium can alter melting points, leading to discolouration or structural inconsistencies during high-temperature processing.
Post-consumer glass often arrives contaminated with bottle caps, closure seals, aluminium foil labels, steel wire from reinforced glass, and various metal fixtures. Construction glass may contain aluminium frames, steel reinforcement, and metal spacers, while automotive glass frequently includes metal clips, antennae, and sensor brackets.
Traditional glass recycling has relied heavily on manual sorting and visual inspection, which are labour-intensive and cannot consistently detect all contaminants, particularly fine metal particles embedded in cullet or concealed within multi-layered glass.
BlakerTech provides advanced, bespoke magnetic and eddy current separation solutions designed to handle both bulky and fine metal fractions, ensuring ultra-clean cullet, protecting downstream processing equipment, and maximising operational efficiency. Our systems enable glass manufacturers to achieve the high purity standards required in contemporary production while preserving the integrity of recycled glass streams, addressing challenges that conventional methods cannot.
-
Flat Glass Recycling
-
Flat glass recycling includes materials such as window glazing, car windscreens, mirrors, solar panels, and other flat glass products. These streams often contain embedded steel or aluminium components, making metal separation essential for producing clean cullet.
BlakerTech’s MagThro Eddy Current Separator efficiently removes non-ferrous metals, including aluminium, copper, and brass, from crushed flat glass. It delivers consistent high-throughput performance, reliably recovering both fine and heavy metal fractions even in contaminated or challenging streams.
By integrating MagThro into flat glass recycling, facilities can meet strict purity standards, maximise metal recovery, protect downstream equipment, and improve operational efficiency, unlocking greater value from glass waste streams.
-
Hollow Glass Recycling
-
Container glass recycling involves post-consumer bottles and jars, where closures, seals, and lids are often made from aluminium or other non-ferrous metals. Glass manufacturers operate under strict quality specifications, and even small metal fragments can cause defects or damage to processing equipment.
BlakerTech’s MagThro Eddy Current Separator integrates seamlessly into glass recycling lines, efficiently removing ferrous and non-ferrous metals from high-volume streams. Designed to handle variable material flows typical of bottle bank collections, MagThro ensures consistent, high-quality output, protecting equipment and meeting the stringent standards required for modern glass production.

Your Questions, Answered
Can’t find what you’re looking for? Get in touch with us today.
-
Can your equipment handle both flat and hollow glass processing?
-
Yes. BlakerTech’s separation systems are engineered to process both flat glass (architectural, automotive, mirrors, solar panels) and hollow glass (bottles, jars, containers) with high efficiency. Systems are custom designed to accommodate material size distributions, material densities, and throughput requirements specific to each glass type.
Advanced features such as precision vibratory feeders and high-intensity eddy current separation ensure consistent removal of ferrous and non-ferrous metals, even from irregular or mixed glass streams, protecting downstream equipment and delivering ultra-clean cullet suitable for modern glass manufacturing.
-
Will your systems damage or break glass particles during separation?
-
Yes. BlakerTech’s separation systems are engineered to protect glass integrity while efficiently extracting metals. The MagThro Eddy Current Separator and precision vibratory feeders remove ferrous and non-ferrous metals from both flat and hollow glass streams with minimal impact on glass particles.
This ensures that cullet remains intact and high-quality, even when processing fragile or irregular glass fragments, while effectively eliminating contaminants that could compromise downstream glass manufacturing.
-
Can you remove metal from laminated or multi-layer glass materials?
-
Yes. Once any plastic interlayers are mechanically separated, BlakerTech’s systems efficiently extract residual ferrous and non-ferrous metals from laminated or multi-layer glass cullet.
This capability enables recycling of high-value automotive and architectural glass, recovering premium, contaminant-free cullet from materials that many facilities would otherwise reject. Our technology ensures effective metal removal while preserving glass integrity, making previously challenging waste streams fully recoverable.
-
What glass recycling volumes justify investing in your separation technology?
-
BlakerTech’s separation systems are suitable for facilities of all sizes, from small specialist operations to plants processing hundreds of tonnes of glass per day. The investment is typically justified by cullet quality requirements, customer specifications, and the premium achievable for ultra-clean glass.
Many facilities experience rapid return on investment through higher-value cullet, reduced reject rates, and improved operational efficiency, making advanced metal separation economically viable across a wide range of processing volumes.
