Specialised induction and eddy current sensor sorting integrated with optics and x-ray technology for maximum separation solutions in STEINERT Unisort.

  • : Melbourne VIC, Australia.

Sophisticated task specific induction sorting, optical and x-ray sensor sorting solutions take separation equipment to new heights for Diamond and Gemstone and plastic sorting applications with mobile sorting and separation equipment made readily transportable into the field. Steinert Global lead the way with sensor sorting technologies.

The idea behind the STEINERT Unisort range of sensor, sorting and separation machines was to bring a range of task specific equipment to the waste and recycling market.

Each of the Unisort range of machines is designed to complete one complex sorting task and to do it extremely well.

Interestingly enough this range of sorting equipment has proven to be of much use in Diamond and Gemstone mining applications, showing an increased yield in value due to the preservation of the size of precious stones recovered. STEINERTs range of sophisticated sensors sees right into the heart of the matter, detecting precious diamond, gemstones, minerals and plastics hidden in the product stream with STEINERT XTS.

Sorting Black and hard to detect objects in the product stream.


With the ability to separate unknown, dark or black plastics from municipal waste streams comes increases to profit from recycled plastics. These stunning innovations to hyper-spectral analysis improves on the conventions of x-ray and near infra red technology to reduce impact on the environment, saving landfill, substitute fuels and waste to energy processing.

Municipal waste, bulk waste, commercial waste and lightweight plastic packaging all fall within the sortable spectrum of the STEINERT Black, expert separation of black plastic material from waste streams.

STEINERT Unisort Blackeye

Recent developments in Hyper Spectral Imaging have led to solutions for the difficult task of recognising Unknown, Dark or Black materials in the waste stream. Recycled plastics now have a brand new product stream in the form of black polymers.

The remarkable STEINERT Blackeye can sort black plastic polymers into respective categories such as PE, PP, PVC and styrenes. Unlike conventional optic color sensors, near ifrared and x-ray the Unisort Blackeye is not limited to any one color, it can detect all color not only dark or black materials.

The Unisort Blackeye is one of the most sustainable and cost effective recovery solutions in plastic recycling today. This is good news for plastic recycling industry professionals as plastic recycling enters a new phase in higher quality, higher value raw plastic for rapid recycling and product turnaround.

Sorting Clear Plastic Film with Unisort Film.

The Unisort Film represents the most current innovations for expert plastic sorting and separation for recycling. This technology opens up new streams of profit from waste material, while saving on landfill and environmental pollution from refuse derived fuels and waste to energy processing.

Using Hyper-Spectral Imaging STEINERT set about the problem of recycling the tons of plastic thrown away in domestic waste everyday. The main problem with recycling plastic waste efficiently, is the fly away characteristic of the product. Using an intricate array of air jets the product is stablized on the feed conveyor, while the hyper-spectral imaging cameras conduct the analysis. The Unisort Film is capable of detecting clear plastic film, reflective plastic film, paper and plastic bags in streams of domestic waste, this technology is an invaluable addition to any municipal waste processing or plastic recycling plant operation.

Plastic recovery processes are boosted due to the use of NIR 3D Spatial and HSI spectral resolution technology.

Hyper-Sectral Imaging is the next evolution of near infrared sensor technology. The Unisort PR is a high resolution infrared camera and sensor which is not only a 3D imaging device but a performs spectral analysis at the same time.

High resolution 3D spatial mapping and chemical composition based upon spectral analysis makes the complex sorting of small and fine particles a breeze. With wide applications for recovering profit from mixed waste streams of recyclable plastic packaging, substitute and refuse derived fuels or plastics from electronic scrap both commercial and domestic, the implications for recovering wealth from waste while conserving resources are evident.

The STEINERT Unisort PR is easily operated via a touchscreen interface, this compact solution will readily integrate into existing waste processing streams and instantly increase efficiency and return on investment.

Sorting flake and fine grain material with STEINERT Unisort Flake.

Unisort Flake effectively does away with the need to hand sort. The Unisort Flake is an efficient solution to sorting and separating plastic, metal or mineral flake grade materials in mixed media waste streams.

The Unisort Flake is convenient to integrate into existing recycling streams due to it’s compact size and easily operated touchscreen controller making the Unisort Flake simply one of the best sorting machines in todays recycling equipment market.

Using Near infrared for color sorting Unisort Flake reliably and accurately effects separation of even the smallest particles of metal, mineral of plastic flake to a high degree of purity by type and color. A Belt feed results in more accurate sorting with better overall sorting characteristics and a 5:1 yield ratio. The widespread application of this plastic, metal or mineral flake sorting solution is proving itself invaluable to the plastic recycling, electronic scrap recovery, scrap metal salvage and sand mining operations, Unisort Flake is a consistent winner across all industries.

Specialized Optic sensors see beyond the range of light.

Colour sensors and HD optic camera technology for reliable plastic recovery operations.

The Unisort C series is a range of color sensitive camera technologies designed with plastic sorting in mind, where color is the specific criteria for separation of plastic bottles, recyclable glass and plastic packaging materials from waste streams.

Transparent plastic materials such as PVC,PET plastic bottles and shredded plastic flake can be efficiently ejected from the product streams in preparation for recycling. Plastics recycling never looked so clean and efficient.

The Unisort C range of optical cameras has also found extensive application for sorting and separating the small amounts of valuable trace metals and minerals present in electronic scrap as well as commercial and domestic waste streams. This is efficient plastic recovery to high degrees of purity for clean product that is ready for recycling processes and fast turn around.

The Unisort C range of camera optic technology has proven it’s worth in all domestic and municipal recycling operations. The recycling of plastics and electronic scrap recovery operations are witnessing unprecedented expert sorting and separation of coarse and fine grade plastics, paper and glass has never been easier and more cost effective to process.

Beyond the sophisticated range of optical and colour sensors that detect value in the product stream, all STEINERT equipment comes with time tested and trusted conveyor feeds and methods of ejection that are reliable, durable and have conveniently maintainable access.

Analyser - Supreme analysis for Substitute Fuels and Waste to Energy Applications.

STEINERT Unisort is the ultimate in Refuse Derived Fuel realtime analysis. Sort and separate valuable recyclable plastic, metal, glass and paper material, once recyclables are recovered you are left with clean product for sale for substitute fuels and waste to energy conversion.

The Unisort Analyser provides the best information on the calorific value of product as it passes the sensor in real time. Near infrared technology and Hyper-Spectral imaging sensors push thermal recovery of materials for processing into the next phase.

The Unisort Analyser offers realtime near infrared spectroscopy to identify chemical composition of objects on the conveyor feed, with realtime calculations and output of such useful metrics as calorific value, material composition, PVC and water content and concentration in waste streams.

This is state of the art technology to get the most out of substitute and refuse derived fuels while maintaining low impact on landfill and environmental emissions.
