The centerpiece: Cleansort MetaLIBS

MetaLIBS – The brain of our Cleansort LIBS technology

MetaLIBS is the central analysis module and heart of Cleansort LIBS technology. It combines high-precision laser technology, spectrometers, optics, and a computing unit in a compact, robust system. Thanks to the patented, highly efficient MetaLIBS technology, laser ablation can be combined with laser emission spectroscopy (LIBS) at the highest level.

The result: a complete chemical analysis of the base material in just a few thousandths of a second without being affected by coatings or surface impurities.

With MetaLIBS Cleansort provides reliable real-time data on material composition. In this way, we create the basis for precise, unmixed separation and maximum recycling efficiency.

Big Data

Using the drop & eject principle, MetaLIBS analyzes every single part individually. This creates maximum data transparency and opens up new potential for added value, even in the supposedly “bad” fraction.

Plug & Play

Commissioning the MetaLIBS system is quick and uncomplicated. With just 5 plug connections, your sorting runs smoothly and reliably, without any complex installation.

Hardware & Software

The MetaLIBS hardware and software were developed in-house. This allows us to guarantee perfect interaction between all components for maximum precision and reliability in the sorting process.

Efficient pre-cleaning at full speed

With a conveyor belt speed of up to 3 m/s, our technology enables up to nine laser pre-cleaning steps in series. For common coatings in the aluminum sector, we achieve an ablation depth of 70 to 100 µm per cleaning step. This high cleaning performance allows reliable analysis of even heavily contaminated, coated or painted recyclable materials.

Material detection with LIBS – precise, fast and non-destructive

Laser-induced breakdown spectroscopy (LIBS) can be used to determine the characteristic “fingerprint” of a material in real time and with a high degree of reliability.

A focused laser beam vaporizes a tiny amount of the material close to the surface. The resulting plasma emits light with specific wavelengths which allow conclusions to be drawn about the elemental composition of the material.

Precise alloy determination with LIBS

By analyzing the emitted spectrum, the exact alloy of a metal can be clearly identified.

LIBS not only enables differentiation between main material groups such as steel, copper or aluminum, but also precise classification within a material group. Even specific alloys – such as aluminium 6082 from the 6000 series – can be clearly identified and separated by type.

This precision forms the basis for high-quality material recovery and sustainable recycling management.
