Production of GEOCELL foam glass

Production of GEOCELL® Foam Glass Aggregate

The raw material: waste glass

The raw material for GEOCELL® expanded glass is recycled glass. This valuable secondary raw material is reprocessed using collection systems.

GEOCELL® expanded glass is made from selected glass fractions that are not used for the production of bottles and glasses. GEOCELL ® closes a gap in the recycling cycle and conserves natural resources.

 

The production process:
First, recycling glass is finely ground, mixed and shaped. The so-called green grain is then sintered and foamed (expanded) in the rotary kiln. This process creates light, round grains with a closed, fine pore structure. After cooling, the cream-white granules are divided into individual grain fractions by sieving.
