Glass Taxonomy & Recovered Materials

Glass Materials & Recovery

From automotive windshields and architectural laminated glass to precision-graded glass powder and reclaimed PVB polymers — explore Aavishkar's complete range of recovered glass materials.

Glass Cullet Glass Powder & Mesh Grades Windshield Recovery & PVB

Recovery Pathway

Source Material → Process → Recovered Output

Every glass product starts with a verified feedstock stream and passes through dedicated separation, sizing, and quality stages.

Source Feedstock

Automotive windshields, architectural laminated glass, flat/float glass, container glass, and verified specialty glass streams.

Windshield Glass Flat / Float Glass Container Glass Laminated Glass

Separation & Processing

Delamination, mechanical-chemical separation, magnetic/eddy cleaning, crushing, grinding, sieving, and quality inspection.

Delamination Crushing & Sizing Sieve Grading QA / NABL Lab

Recovered Outputs

Clean cullet, precision-graded glass powder (20–400 mesh), reclaimed PVB polymer, and specialty recovered materials.

Glass Families & Composition

Understanding glass composition matters for proper recycling. "Type" can mean chemical family, source stream, physical form, color, or particle-size grade — these must remain as separate catalog fields.

Glass Family	Composition / Characteristic	Common Uses	Recycling Note
Soda-Lime-Silica	Silica-based glass modified with sodium and calcium compounds. Most common glass family.	Bottles, jars, window/float glass, tableware	Common container and flat-glass streams. Cross-contamination can affect suitability.
Borosilicate	Contains boron oxide with silica; low thermal expansion, resists rapid temperature change.	Laboratory, cookware, specialty products	Keep separate unless processor has approved mixed recipe.
Aluminosilicate	Silica with high alumina; formulated for chemical durability and performance.	Display, specialty/technical glass	Require source records or material analysis; do not infer from appearance.
Lead Crystal	Some traditional crystal contains lead oxide. "Crystal" may refer to regulated definitions.	Decorative tableware, specialty items	Keep out of general recycled cullet; assess restricted substance rules.
Glass Fiber / Fiberglass	Glass formed as fibers; milled fiber is particulate/fiber, not standard glass powder.	Composite reinforcement, engineered products	Distinct recycling stream; confirm process capability and handling controls.
Laminated Automotive / Architectural	Glass plies bonded by PVB interlayer; composite until delaminated.	Windshields, laminated building glazing	Must be processed to separate glass and polymer; report output purity with defined test methods.

Recycled Glass Product Forms

Separating how the material was recovered and processed from what it's made of.

Mixed / Color-Sorted Cullet

Broken glass from a known source; may be mixed, clear, green or amber.

Key Fields to Publish:

Source stream, color, size range, contamination limits, moisture, packaging

Crushed Clear Glass

Crushed material described as clear. "Crystal clear" describes appearance, not chemistry.

Key Fields to Publish:

Color/appearance, particle range, source, sharpness/dust handling

Glass Powder

Ground glass sold as powder; particle distribution may be broad.

Key Fields to Publish:

Feedstock, composition, color, particle-size distribution, sieve method

Glass Micro Powder / Fine Grades

Supplier-defined fine grades, sometimes represented by mesh number.

Key Fields to Publish:

Mesh designation, actual aperture basis, measured distribution

Reclaimed PVB

Polymer recovered from laminated glass — flakes, scrap, or pellets.

Key Fields to Publish:

Residual glass, moisture, polymer condition, color, downstream limits

Milled Fiberglass

Short milled fibers or powder-like material; morphology matters.

Key Fields to Publish:

Fiber-length distribution, diameter, binder/sizing, bulk density, SDS
