Plastics profit from previously unsortable objects with increased efficiency through the exclusive Steinert Global Unisort products.

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

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 equipment market. Unisort is an exclusive range of sorting and separation technologies from STEINERT Global

Analyser - Supreme analysis for Substitute Fuels, Refuse Derived fuels and Waste to Energy Applications.

STEINERT Unisort Analyser

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.

STEINERT Unisort Analyser is the ultimate in refuse derived fuel (RDF) realtime analysis. Sort and separate valuable recyclable plastic, metal, glass and paper material, once recyclables are recovered you are left with clean product for immediate sale as substitute fuels for 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.

Sorting Dark, Black and Unknown objects from the product stream - Now possible using STEINERT Global solutions.

STEINERT Unisort Black :

Black and Dark objects in the product stream have, up until this point been very hard to detect and the task was always left to hand sorting to meet the complex need.
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, dark and unknown objects from waste product streams.

STEINERT Unisort Blackeye :

Recycled plastics now have a brand new product stream available in the form of black polymers, the Unisort Blackeye represents state of the art black and dark plastic object detection.Recent developments in Hyper Spectral Imaging have led to solutions for the difficult task of recognising unknown, dark or black materials, transparent objects and objects that do not reflect light in the waste stream.

The remarkable STEINERT Blackeye can sort black plastic polymers into respective categories such as PE, PP, PVC and styrenes. Unlike conventional optic colour sensors, near infrared and x-ray equipment, the Unisort Blackeye is not limited to any one colour, it can detect all colours in the visible light spectrum not only dark, non-reflective or black materials.

The Unisort Blackeye is one of the most sustainable and cost effective recovery solutions in plastic recycling machines and equipment on todays market. 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.

Specialised optic sensors see colours beyond the range of light.

STEINERT Unisort C :

The Unisort C series is a range of colour sensitive camera technologies designed with plastic sorting in mind, where colour is the primary criteria for separation. Unisort C is integral to complex optical based sorting tasks such as those found recycling plastic bottles, glass and plastic packaging materials from plastic and municipal solid waste streams.

The Unisort C range of camera optic technology has proven it’s value to all household and municipal recycling operations, plastics recycling and electronic scrap recovery operations. Expert sorting and separation of coarse and fine grade plastics, paper and glass has never been easier or more cost effective.

Transparent plastic materials such as PET plastic bottles and plastic flake can be efficiently ejected from the product stream when recycling. Plastics recycling never looked so clean and efficient.

The Unisort C range of optical cameras has also found extensive application in the sorting and separation of electronic scrap and well as commercial and domestic waste streams of high quality and purity for plastic recovery of clean ready to recycle plastic product for fast turn around.

STEINERT Unisort Film

The Unisort Film represents the most current innovations for expert sorting and separation of plastics for recycling. Open up new streams of profit from waste material, while saving 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 stablised 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.

Sorting shredded fine fraction Plastic flake from mixed media waste streams.

STEINERT Unisort Flake :

Secondary waste recycling makes a comeback with Unisort Flake, an efficient solution to sorting and separating plastic, metal or mineral flake grade materials in mixed media waste streams.

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 over sort characteristics and a 5:1 yield ratio. The widespread application of this plastic, metal or mineral flake sorting solution, to the plastic recycling, scrap metal recovery and sand mining operations, making the Unisort Flake a consistent winner across industries.

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 most cost effective sorting machines in todays recycling equipment market.


Hyper-Spectral-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 also performs a rapid spectral analysis at the same time.

Unisort PR is expert for plastics recovery using near infrared (NIR) 3D spatial and HSI hyper-spectral-imaging with high definition spectral resolution for complete high yield clean plastic product for reuse.

High resolution 3D spatial characteristics and chemical composition information, based upon spectral analysis, material density and atomic composition displayed to the operator in high definition make sorting small fine flake and complex sorting tasks a breeze.

Easily operated via a touchscreen this compact solution will readily integrate into existing waste processing streams and eliminate the need for hand sorting, instantly benefiting from increases in efficiency and return on investment.

With wide applications for the complex sorting of mixed media waste streams containing recyclable plastic packaging, substitute and refuse derived fuels or plastics and metals from shredded electronic scrap both commercial and domestic - the implications for recovering wealth from waste while conserving resources are evident.

Beyond the sophisticated range of 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.
