With a very low environmtal footprint, glass can be endlessly recycled and up-cycled.



Every ton of glass that is recycled saves more than a ton of the raw materials needed to create new glass, including: 1,300 pounds of sand, 410 pounds of soda ash, 380 pounds of limestone, and saves 2 cubic yard of landfill space. In the USA around 7 million tons of glass is ending up on the landfill every year - or 280,000 semi truck loads.

Glass can be endlessly recycled and up-cycled with a very low environmental footprint. 
Please recycle!



The manufacturing process takes 100% curbside recycled glass powder and mixes it with a foaming agent.
The mixed powder is sent through a kiln and softened. During this process, the foaming agent creates bubbles within the softened glass and this creates foamed glass aggregates.
The manufactured foamed glass aggregates are approximately 15% of the bulk unit weight of typical aggregates.
This makes the material one of the lightest aggregates available on the market. 



Foamed glass has a unique combination of properties that make it highly useful for a wide range of applications: it is lightweight, rigid, compression-resistant, thermally insulating, freeze-tolerant, nonflammable, chemically inert and nontoxic, rodent- and insect-resistant, and bacteria-resistant. Foam Glass Aggregates facilitate quick construction, have low transport costs, and it is easy to handle. The combination of properties makes Foam Glass Aggregates useful in construction, agriculture, horticulture, civil engineering, and environmental applications. 

Closed Cell vs. Open Cell
Foam Glass Aggregates

Closed Cell Foam Glass Gravel is hermetically sealed, the internal cells are closed.
Advantage: Continuously ultra lightweight, excellent drainage, defined properties for construction, great R-value for the lifetime of the building, vermin proof, low capilarity, acid and chemical resistant, high compressive strength, economical, and ecological.
• Lightweight embankments
• Bridge abutments
• Bulkheads and retaining walls
• Insulating backfill for buildings and road base
• Lightweight and insulating backfill for utilities
• Permafrost protection
• Floating island
• Shallow foundations
• GeoFoam replacement

Open Cell Foam Glass Gravel has a partially open and connected cell structure to allow water and air (gases) to penetrate and exchange.
Advantages: Super lightweight even under saturation, freeze-thaw resistant, high capilarity, microporous absorbent, catalyst with outstanding properties for vegetation, hydroponics, filtration, and bioretention. High compressive strength.
• Wastewater and stormwater filter media
• Green roofs and plaza decks
• Slope stabilization
• Creates natural strata for stronger root growth
• Bioswales, rain gardens
• Structural soils
• Golf course, turf grass amendment
• Floating island with aquatic plants for pollution removal 


Construction stone, sand or rocks are heavy. Shipping and handling is costly with a high Carbon footprint.

Lightweight aggregates (LWAs) are less heavy than stone or sand.

Ulta lightweight aggregates like Foam Glass Gravel are saving the most shipping handlings costs and they are easy to install. 1 truck load instead of 5 truck loads
