From returnable glass to multicellular glass

Fornax A/S recently completed one of the business's largest assignment so far. A 45 metre long conveyor oven that will be used for foaming returnable glass for a Norwegian customer.

It is 45 metre long, approximately 2.6 metres high and 2.3 metres wide and processes various returnable glass materials that would otherwise end in landfill.

The material is ground with activators and is heated in the oven to approximately 1000 degrees C, at which it becomes a porous glass material that in structure resembles a gas beton. This has extremely good insulation properties and is used in road construction as a building material and in other contexts where low weight and high insulation properties are required.

This is not the first oven Fornax has developed and built in collaboration with the customer but it is the longest!

So long that the production premises at Fornax had to be extended in length - and so the basis for even greater challenges in the future are created!
