ARCHITECTURAL GLASS INVENTORY SERVICE
WE PROVIDE ON-SITE SERVICE FOR THE BUILDINGS TO BE DEMOLISHED OR RENOVATED
THE ANALYSIS COVERS FACADE GLASS AND INTERNAL GLASS.
The technical assessment includes:
- Identification and marking of glass types to distinguish glazing suitable for recycling from that which is unsuitable for recycling. The analysis, performed on-site at a building designated for demolition, covers facade glass as well as internal glass based on composition and glass category (according to the classification below). During identification, the glass is sorted into three categories: recyclable, laminated recyclable, and non-recyclable.
- The glass will be marked to ensure proper sorting for the dismantling process. Counting the quantity of each type of glazing (divided into the above categories) for better on-site logistics organization. Collecting information on sizes, quantities, and locations of glass allows for more accurate estimates.
- The material inventory report is the result of the service.
- A recycling or disposal offer for facade materials can be prepared based on the technical inventory report by Saint-Gobain Glass partners, who offer recycling services if you are interested in recycling and/or disposal of glass.
BUILDING GLASS ANALYSIS FOR DEMOLITION NEED FOR GLASS IDENTIFICATION
THE NEED FOR GLASS IDENTIFICATION
To enable glass recycling in a closed loop, it is recommended to conduct a verification before dismantling.
This will clearly and understandably define the content of specific glass fractions for demolition, maximizing the chances of increasing the amount
of building glass subjected to recycling and, most importantly, allowing it to return to the furnace for the production of new float glass.
GLASS TYPE IDENTIFICATION
The first step is identifying the type of glass from the building designated for demolition. Post-consumer glass requires recycling to be reused. Therefore, we have defined 3 categories:
RECYCLABLE GLASS:
Compatible with flat glass recycling in a closed loop.
This category includes:
- float and low-iron glass,
- colored glass (used only for the production of colored glass), e.g., PARSOL® (such glass must be separated during demolition),
- coated glass by magnetron sputtering,
- glass with a pyrolytic coating,
- annealed, thermally strengthened, and tempered glass.
Tempered glass
Tinted glass
Coated glass
Extra-white glass
Etched glass
LAMINATED GLASS
Laminated glass Glass laminated or coated with film suitable for recycling.
Compatible with flat glass recycling in a closed loop.
Laminated glass
Consists of two layers of glass bonded together with a polymer layer – only if made from standard PVB (polyvinyl butyral) or EVA (ethylene-vinyl acetate copolymer).
Film-covered glass
This type of glass is covered with a plastic film (stickers, frames). This type of glass should be treated the same way as laminated glass (recyclable laminated glass).
Laminated glass
Folm-covered glass
Laminated glass requires additional treatment during the recycling process - the film from the laminate must be removed in order to reuse the glass. this fraction is therefore separated out.
NON-RECYCLABLE GLASS
Glass incompatible with flat glass recycling in a closed loop.
This category includes:
- Fire-resistant glass with an intermediate layer,
- Laminated glass made from materials other than PVB and EVA,
- Decorative glass, mirrors,
- Borosilicate glass,
- Solar panels,
- Electrochromic and photochromic glass, glass with electrical components,
- Enamelled glass, digital printing,
- Reinforced glass.
Packaging glass
Fire-resistant glass
Contaminated glass
Thick glass, over 12 mm
Patterned glass
Electrochromic and photochromic glass, glass with electrical components
Other types of glass and materials:
- glass-ceramic elements: stoves, etc.,
- glass bottles and other containers,
- tableware (glasses, cups, carafes, jars, etc.),
- crystal (lead glass),
- laboratory glass (test tubes, beakers, etc.),
- light bulbs and lighting fixtures,
- decorative glass elements,
- TV, computer screens,
- construction waste (aggregate, concrete, rubble, sand...),
- items containing asbestos, putty (seals in old windows),
- glass shards contaminated with any other waste,
- other components of an insulated glass unit (spacer frame, sealant, desiccant, corner connectors, inserts).
This type of glass is suitable for disposal or use by other industries.
