Greener glass

With the world’s most advanced optical sorting technology, we transform waste into cullet in four streams of colour with no loss in purity or quality, thereby creating an infinite recycling loop.

Our cullet solutions help customers to meet their environmental challenges and to remain competitive in increasingly challenging markets.

Our latest sorting technology is transforming waste collection in Europe, making it possible to retrieve and recycle more glass from mixed waste than ever before.
