1. Raw Glass
Raw glass is conveyed into the plant and a powerful magnet removes and metallic particles which are sent to recycling.
2. Drying & Cleaning
The glass is dried and any unwanted material such, as labels and organic residue, is removed. The clean, dry glass is then transferred to the grinding mill in a continuous operation. Filtration systems capture any dust and is fully recycled

3. Milling
The glass is passed through a high-speed roller mill to form a very fine powder. The particles are approx. 0.03mm size.

4. Silos
The glass powder is stored in one of 5 x silos
5. Mixing
The glass powder is transferred to a mixer and a small amount of foaming agent is added. The mixture is then deposited on a slow-moving belt which travels through the kilns in a continuous operation.
6. Kilns
The mix is heated in a controlled profile. It semi-melts and begins to expand as fine gas cells are formed. The expanded foamed glass exits the kilns approx. 3-4 times the original volume.

7. Cooling
At this point once fully cooled, the Foamglass aggregate is at full strength, stability and ready for use.

8. Storage & Grading
The Foamglass gets conveyed outside ready for crushing and screening to the necessary grades of size. The resulting product is exceptionally low-weight, strong, angular, clean and a superb thermally insulating material.
