Sorting of glass

To minimize glass losses, Redwave has designed glass processing solutions by maintaining a consistent and evenly distributed material flow into and through the system. For this reason, Redwave selects the best available systems for pre-processing the glass stream and sources them from reliable subcontractors. This ensures that the input material is optimally prepared for the sorting process using sensor-based sorting machines.

The sorting machines, in combination with the AI software “Mate,” provide customers with a plant monitoring system that improves overall plant productivity in the long term.

Until now, dark and thick glass could not be distinguished from opaque materials such as ceramics due to low transmission values, resulting in high-quality glass ending up in the reject stream. It is therefore important to also sort dark glass, as this helps reduce glass losses and increase plant efficiency.

Separation of glass

Redwave can sort glass in the following colours:

		Flint glass
		Brown glass
		Semi-coloured glass
		Green glass
		Dark glass

Sorting process of glass

The proces of sorting glass consists of multiple stepswhere the desired materials are separated step by step until a clean end product is achieved:

During the separation proces inpurities and unwanted materials are being removed. This can e.g. be:

		KSP
		Plastic
		Glass ceramic
		Metal
		Lead glass

“The separation and sorting of glass provides an economic benefit, a higher plant capacity, and a high quality/purity in the final fractions. Redwave has developed several machines that can sort glass as well as the associated impurities. You can read more about the sorting machines here: CX/CXF og XRF-G.
