🚀 STEINERT MSort is developing a cost-effective solution for HR glass separation
Lukas Armatys, Managing Director of STEINERT MSort in Wedel, is proud of his team. The product development team has solved a problem for which other manufacturers require a much more expensive technology to solve. "In addition to the usual impurities such as CSP and metal, we can now detect and remove heat-resistant glass and plastics in a single step, in combination with colour sorting.
As this new product is available as an upgrade for all existing sorting systems, purchasing this sorting solution is much more cost-effective than the options of competitors. And there's no need for complex modification work either," says Armatys. This is very good news for all glass recyclers, no matter whether they work with flat glass or container glass. This is because there is no need for complicated and costly work involved in removing the old and installing the new sorting systems; the new sorting solutions are simply added to the existing machine via an upgrade. Why HR (heat-resistant) glass is an impurity and how to remove it
To produce high-quality recycled bottles and glass, recyclers need cullet suitable for remelting packaging glass. However, HR glass differs in chemical composition and melting behaviour, making it a critical impurity that must be removed.
The challenge increases when HR glass and plastics resemble target materials like flint glass. To address this, developers use cost-effective sensor technology based on wavelengths outside the visible spectrum, enabling accurate detection. This is essential, as many types of HR glass — such as cookware, oven glass, ceramic hobs, and fireplace screens — should not enter the standard recycling stream.
MSort AX has been operating reliably for months
This new development has already proven its worth over a considerable period of time with a long-standing glass recycling customer. The 14-year-old sorting system is now operating with the new development in this case. The latest tests show that the MSort AX detects and removes HR glass with 99% accuracy. This is efficient for the customer, as the system did not have to be modified – just a few days were needed for the upgrade and the results are excellent.
For anyone interested in taking advantage of these new opportunities, sorting tests are available at the Test Center in Wedel.
