Schönberg, November 2011
S+S Inspection Inc, the US subsidiary of the Bavarian company S+S Separation and Sorting Technology GmbH, has relocated its headquarters from Niagara, New York, to Bartlett, Illinois, near Chicago. Bartlett is about 20 minutes from O'Hare International Airport in Chicago. Relocation had become necessary because S+S intends to clearly expand its North America business operations. Comprehensive service for S+S customers in the USA mainly from the plastics, food, and recycling industries can thus be guaranteed.

Relocation to the new headquarters in Bartlett was organised by S+S North America General Manager Werner Fleps. In addition to an extended design and manufacturing department S+S in Bartlett now also features a Customer Service Center that is equipped with a sorting line for customers from the recycling industry, and a full range of metal and contaminant detectors - from inductive through to X-ray - for customers from the plastics and food industries.

The recycling demonstration line is equipped with proven sorting and separating systems and allows customers to perform realistic real-time tests. Machine settings are optimised to match customer-specific requirements. The Customer Service Center also guarantees the quickest possible delivery of new machines and spare parts to S+S customers, which is why machine and spare part stocks have been clearly increased.

Werner Fleps: "If S+S intends to grow in the USA, closeness to our customers is of decisive importance. This means that we need a facility with a local technical center. For US customers Germany simply is too far away for obtaining information about equipment and technologies. To further back up our growth we also have strengthened our US team with Tracey Hartje and Tony Rampino."

Bio bottles? No problem! S+S sorting systems for unmixed, contaminant-free, high-quality secondary raw materials Schönberg, October 2011 At the PETpoint 2011 trade fair that will be held from 9 to 11 November in Nuremberg, S+S Separation and Sorting Technology GmbH presents sorting systems for PET recycling in hall 7A, stand 530. The big challenge in PET recycling is that bottles or flakes must be separated to provide unmixed and contaminant-free output materials. S+S has developed solutions that separate contaminants from PET material flows and sort these material flows into unmixed fractions. Using state-of-the-art sorting technology that is able to separate huge mass flows into various secondary raw materials in a very short time is an important element for an economically efficient recycling process. PET recycling has become an essential factor for the saving of crude oil and thus for the reduction of CO2 pollution. Every recycled PET bottle has a crude oil equivalent of 25 gram. In view of the global recycling quantity of 4.53 million tons of PET bottles per year this means a saving of crude oil of approximately 3.7 million tons. Even packaging that at first glance may seem to be ecologically unfavourable, such as non-returnable PET bottles, due to its recycling thus becomes ecologically valuable packaging that in its eco-balance is in no way inferior to competitors like returnable glass bottles. More than 80 percent of the PET recycling companies in Germany, and more than 60 percent of the European recycling companies use S+S polymer, metal, and colour separators for the reliable separation of contaminants. Polymer separators with multi-spectral sensors are used to detect contaminants and plastic types. In PET recycling these systems in fully-automatic operation separate unwanted plastic types from the PET material based on the infrared absorption of the various plastic types. They for example remove PVC contents or bioplastics such as PLA, which otherwise would considerably reduce the quality of the recycled material or would even make high-quality material recycling impossible. Against the background of an increasing use of "bio bottles" that up to 100 percent are made of vegetable raw materials and from the outside cannot be distinguished from conventional PET bottles, this is an important sorting criterion. Contaminant separators with inductive sensors reliably remove all kinds of metals from mixed PET materials. While conventional metal separators can separate certain types of metal like stainless steel only to a very limited extent, S+S contaminant separators perform this separation task without any problems – irrespective of the type of metal. Colour separators with optical sensors in fully automatic operation separate off-colour contaminations (e.g. coloured from clear, non-transparent bottles) from a PET material flow. Optical inspection is performed by high-speed cameras. The optically relevant information is evaluated, and the wanted or unwanted colour fractions are correspondingly separated. The S+S Flake Purifier performs up to three sorting tasks (plastic types, metal, and colour) in one go.

At FAKUMA 2011 to be held in Friedrichshafen from 18 to 22 October 2011, S+S Separation and Sorting Technology GmbH, Hall B1, Stand 1302, will be exhibiting metal separators from the PROTECTOR family and EXRACTOR in line magnet systems for installation upstream of injection moulding machines for "Last-Chance" metal detection.

The Extractor inline magnet was developed for plastics industry applications to protect extruders, injection and blow moulding machines. In previous versions the three neodymium magnetic rods were of 6000 Gauss strength at the effective surface, the external side of the stainless steel casings, where material contact takes place. S+S now has increased this power to 8000 Gauss with no increase in price whilst maintaining the same compact dimensions.
Installed directly on the infeed, the Extractor separates ferromagnetic contaminations from the granulate immediately before processing reducing expensive repairs and machine downtime. The compact system design in combination with customer-specific connectors and adaptor plates can easily be retrofitted and will withstand dynamic loads up to 500 kg (shear loads up to 50 kg). The EASY CLEAN feature allows quick and efficient system cleaning. ATEX certified magnet separators are also available to meet stringent explosion protection requirements.

The range of products on the stand is completed by metal detectors integrated into conveyor belts, and metal separators for vacuum and pressure conveyor lines.

Information about plastics sorting

The use of recycled material is much more extensive than in the past and S+S is a leader in product sorting for plastics recycling. One of our expert staff will be available on the stand, Wednesday, 19 October 2011, to answer any questions on the subject of optical sorting by colour and polymer type.

At the K 2010 trade fair S+S presents contaminant detectors and separators for production and recycling

Schönberg, August 2010
At the K 2010 plastics trade fair in hall 10, stand 10E60, S+S Separation and Sorting Technology GmbH presents comprehensive separation and sorting solutions for the complete life cycle of plastics. The systems that are presented comprise metal detectors and separators as well as magnet systems for all production stages and conveying types in plastics processing, and contaminant separators for plastics recycling. With the main subject of "All about PET" S+S here focuses on PET processing and recycling. All the systems presented at the trade fair are highly sophisticated solutions that represent the result of 30 years of experience.

Reliable processes in PET processing and in the production of caps and closures
At the K 2010 S+S presents innovative solutions for the problem of protecting high-performance injection moulds for preforms or caps and closures against metal contaminations to increase the economic efficiency of the complete production process. In this field S+S presents two new systems:

With the Protector-XHT S+S has successfully developed a metal separator in high-temperature version for processing temperatures of up to 200ºC. The separator is installed directly at the inlet of the injection-moulding machine or after the drier and thus inspects all the fed materials at the last chance control point.

High-performance moulds, e.g. for bottle caps with up to 96 cavities (moulding nests) and more require metal separators with highest scanning sensitivity to protect the delicate hot-runner systems. For this application S+S has developed the Protector-HR metal separator.

Innovative technology for highest value creation in PET recycling
More than 80 percent of all the PET processing companies in Germany and more than 60 percent all over Europe use S+S separators for the reliable separation of contaminants. S+S sorting systems are ideal for PET flake sorting because they guarantee highest product quality that allows a further use of the recycled material in the food sector. Since quality requirements for recycled materials are high and such materials must be competitively priced against new materials, S+S sorting systems with their outstanding flexibility are a future-proof investment because they employ sophisticated technologies and provide high-purity material fractions.  

Schönberg, July 2010
RecyPET AG was established in 1998 and has operated Europe’s first bottle-to-bottle PET recycling plant in Fraunfeld, Switzerland, since September 2000. The PET recycling plant operates in accordance with the URRC technology developed by the United Resource Recovery Corporation (USA) together with Coca-Cola and has an input capacity of approx. 18,000 tonnes per year. Four further plants in Europe now use this technology.

 In Switzerland the collected beverage bottles are sorted in five sorting plants according to colour and quality, compressed into balls and delivered to RecyPET AG, among others, for processing. RecyPET’s goal is to close the material cycle for PET beverage bottles. The recyclate produced is used among other things for the production of new PET beverage bottles, food packing films, other films, etc.

S+S Separation and Sorting Technology supplied a metal separator of the type PETMAG to RecyPET as long ago as 2001. The PETMAG separates metal contaminants of all kinds from PET flakes. Since the flakes are also to be sorted according to colour, S+S, in close cooperation with RecyPET, adapted a colour sorting machine originally used in the glass recycling industry to the requirements of PET recycling. The result was the SPECTRUM colour separator. By means of double-sided inspection it was possible even to separate flakes contaminated with the slightest glue residues.

In 2010 the PETMAG metal separator, which during its ten years of operation caused service and spare part costs of barely 2000 Euros, was replaced by a combined system of the latest generation, the VARISORT COMPACT. Colour and metal sensors are combined with one another in this device.

The material to be examined is fed by means of specially adapted vibrating trough conveyors and unites the advantages of chutes and belt systems. This also makes it possible for the first time to remove rubber pieces from the material stream that are difficult to separate using chute technology due to varying friction. The superiority of VARISORT COMPACT over chute systems
with channels lies in the fact that the equipment is easy to clean and blockages due to larger flakes can virtually be ruled out. Even in the case of irregular parts or materials with different
coefficients of friction, the belt feeding system provides for pinpoint ejection in free fall at the end of the belt, after the material has been classified with the sensors. After evaluation of the relevant information, high-speed valves for the material discharge are activated with an appropriate time delay. By means of powerful compressed air pulses, the particles to be separated are diverted from their original drop parabola into a separate shaft.

In comparison to conventional belt sorting systems, the VARISORT COMPACT sorting system is characterised by a compact design requiring little space. Retrofitting in existing plants and the adoption of already existing chute devices is easily possible. The use of high-resolution sensors and state-of-the-art signal processing technologies allows high detection accuracy and the analysis of up to 500,000 parts per second. By means of the free-fall inspection, a very precise blow-out procedure can be realised even with high rejection rates. This is made possible by the large number of high-speed valves, which can perform up to 500 switching cycles per second.

For Kornel Büsser, production manager at the Swiss company RecyPET AG, the long-standing cooperation with S+S has proven its value: “The reliability and ease of maintenance of the S+S units convinced us, together with their performance, particularly in the separation of difficult contaminants.”

All over Europe, electrical and electronic scrap is the waste stream showing the highest growth rates. Since electronic equipment contains the most varied kinds of materials, the recycling of such waste involves high demands with respect to separation and sorting processes. The German plant manufacturer MeWa builds state-of-the-art recycling plants for large international waste management companies.

 

In the United Kingdom MeWa realised a plant where old refrigerators, computers, vacuum cleaners, Hi-Fi systems, and other kinds of electrical waste are processed on two separate lines. For the recycling of high-quality plastics such as ABS (acrylonitrile butadiene styrene) or PC (polycarbonate) and of printed circuit boards MeWa uses three VARISORT N sorting systems made by S+S. "The decision to use S+S systems was based on the high output quality of these VARISORT systems. Only absolutely pure fractions can be sold at a good price in today's difficult times", explains Peter Mayer, sales manager - sorting technology at S+S Separation and Sorting Technology.

 

Innovative technology for outstanding value creation

Polymer separators of type VARISORT N are based on near-infrared technology. At the MeWa facility these systems in fully automatic operation separate plastic types from precrushed electrical waste. Optimally scattered on a fast-running conveyor belt this waste reaches the detection area of the near-infrared detector which determines and locates the plastic types of the passing pieces. The electronic evaluation unit determines the exact position of the unwanted types, and with accurate timing and positioning activates the corresponding nozzles of the air-blast unit. The user can freely select which types of polymers should be separated.

In one VARISORT sorting system the near-infrared sensor is combined with a colour sensor. With this multi-sensor system design the colour of the particle and its plastic type can be combined as sorting criteria, which results in an even higher separation accuracy for the pcb-fraction.

Recycling materials are economically efficient and environmentally friendly

S+S VARISORT N polymer separators are characterised by highest throughput capacities. Sorting is performed at a speed of up to 3m/sec. Air-blast valves that have been specifically developed for this application keep the loss of good material at an absolute minimum. In the recycling of electrical waste VARISORT N separators are an economically efficient solution for the reclaiming of high-quality plastic fractions and of the pcb-fraction. The resulting pure plastics can be profitably returned to the production cycle again, and valuable (precious) metals can subsequently be reclaimed from the separated printed circuit boards.

Flexible and future-proof solutions provided by S+S

Says Peter Mayer, sales manager - sorting technology at S+S: "Recycling companies that produce clean, economically-priced material have the biggest competitive advantage. Because of their outstanding flexibility VARISORT sorting systems are ideal for the sorting of electrical waste. No matter what type of electrical waste should be sorted in the current job, a VARISORT will always optimally perform the sorting task by employing different kinds of sensors. Since the markets for recycled materials are rapidly changing especially in the field of electrical waste, and since quality requirements for recycled materials are high, and recycled material has to compete with the price of new materials, the VARISORT sorting system with its flexibility is a future-proof investment here because the employed technologies are highly sophisticated and the systems provide high-purity material fractions."

S+S Separation and Sorting Technology has completely redesigned its well-known RAPID COMPACT metal separator. The result is the RAPID VARIO PRIMUS which retains all the well proven features of its predecessor eg high scanning sensitivity. The PRIMUS control unit is a new feature. Another important improvement is the fundamental redesign of the separation mechanism which is infinitely adjustable up to 180°, depending on the customer’s requirement. Drop height can also be adapted to meet the customer’s specification as the detection unit and the reject mechanism are designed to be separated. The RAPID VARIO series is primarily used in the plastics industry however it can be used in other industries with similar applications for inspecting freefalling bulk materials. Even the smallest magnetic and non-magnetic metal contaminants are detected and removed from re-granulates and virgin material, thereby reducing machine downtimes and visibly and sustainably increasing productivity.
