STADLER provides amongst others high-tech waste sorting and recycling solutions for the following materials:
STADLER stands for individually planned, turnkey sorting plants for municipal solid waste with a processing capacity of 40,000 t/year up to high-capacity plants with a capacity of 1,000,000 t/year, such as the one we recently successfully constructed in Spain.
Thanks to over 60 plants realised around the world to date, STADLER possesses broad expertise and a high level of experience in the field of municipal solid waste processing.
Municipal solid waste consists of all types of waste generated in the household. In addition to organic waste such as leftover food, this also includes a wide variety of recyclable materials. This type of diverse material composition with a correspondingly highly varied density of between 100 and 300 kg/m3 represents a particular challenge for such plants, because it simultaneously demands a high degree of plant flexibility and robustness.
Although disposal of the material essentially takes place in a similar way, the material properties vary from country to country. The fact that STADLER was involved in developing the first plants of this type from the outset is extremely useful in this regard. STADLER is familiar with each material in the individual countries, and knows which plant model will produce the best overall results for the customer in each individual case.
STADLER commissioned the first plant of this type back in 2008. Since then, more than 25 such STADLER sorting plants have gone into operation, with installations in France, England and the USA in particular.
Nowadays, separation of the organic fraction from recyclable materials takes place in many countries around the world. However, the dry mixed recyclables contain greatly differing components depending on the country. For STADLER, this means it is necessary to devise the best possible overall plant concept for each type of material. The average composition exhibits an approximate density of 80 kg/m3. Since paper and cardboard have by far the highest density in this mixture, the overall density varies depending on the proportion of these two recyclables. Because the proportion of films and plastic trays in the total volume is constantly increasing, both the composition and total density will change in the future.
Commercial waste consists of a wide range of different products, substances and materials with greatly differing volumes and a rather high density. This means that high demands are placed on the machinery used. This poses no problem, thanks to our extremely high quality standards.
Almost twenty years of experience in commercial waste sorting – 15 plants constructed worldwide – makes us an expert in this segment.”
Our commercial waste sorting plants separate all substances or products that are generated in trade and industry. With a density of approx. 150 kg/m³, commercial waste exhibits a relatively high weight.
Thanks to our broad wealth of experience, our high-performance plants achieve a high degree of sorting purity – which is particularly vital today, in times of worldwide plastic waste pollution.
With STADLER having constructed over 50 plants around the globe in the past 15 years, we are pioneers in the field of sorting all types of lightweight packaging.
Packaging resulting from everyday use is sorted in our sorting plants for light packaging. Such waste consists of various types of plastics / polymers, aluminium, tin plate or composite materials, such as drink cartons.
One of our areas of expertise is the pre-sorting of bottles for washing plants. Thanks to our extensive experience, we achieve a high degree of purity in the final output fraction, which enables seamless further processing.
For more than ten years now, STADLER has been planning, designing and building high-performance plants for sorting plastic bottles worldwide. Over 15 plants have been put into operation worldwide to date.
Pressed mixed plastics and loose mixtures of plastic bottles are processed within the framework of plastic bottle sorting.
The subject of film sorting has only recently become a focus of the recycling industry. STADLER identified the demand – and responded immediately. We were the first plant constructor to develop a corresponding sorting concept, which is specially tailored to the properties of film produced from different polyolefins.
Due to high demand, several STADLER film sorting plants are currently in continuous operation in Germany, the Netherlands and Bulgaria.
In STADLER film sorting plants, the various polyolefins are differentiated from each other and separated accordingly.
Equipped with our 4-wave ballistic separator PPK, the paper and cardboard sorting plants designed by us are genuine all-rounders. The result is material fractions with the highest degree of purity.
With more than a dozen paper and cardboard sorting plants built by STADLER over the past 15 years, we are experienced professionals in this field.
STADLER paper and cardboard plants are predominantly used for sorting large quantities of waste paper and cardboard from the commercial and municipal sectors.
Refuse derived fuels for cement production must be of consistently high quality. Our plants therefore preferably use mechanical separation processes.
From the first plant in 2005 to date, we have commissioned ten refuse derived fuel plants. According to our customers, each of the plants has more than satisfied expectations.
Our refuse derived fuel plants professionally process commercial waste as well as pre-sorted waste containing plastics, which serve to produce high-quality refuse derived fuels for cement production.
Sorting plants for the so called "e-waste" are required to satisfy the highest demands: before separating different types of metals and plastics, it is also necessary to detach the valuable materials through shredding and classifying out of the composite of different materials, and subsequently feed them into the recycling loop.
Working in cooperation with weeeSwiss Technology AG (which has been active in the field of electronic and electrical waste for over 25 years now), STADLER develops high-quality sorting plants for electrical waste which are unrivalled in terms of sorting quality and throughput.
The material mix in the field of electronic and electrical waste includes a wide variety of electrical devices and electronic components of all sizes and categories. Be it big and small household appliances, mobile phones, computers, printers, monitors, televisions, refrigerators and air conditioning systems.
The large-volume material mix with a particularly high density requires an especially robust plant construction with high-performance components. In order to satisfy these requirements, STADLER has developed a true powerhouse the ballistic separator STT6000 specifically for this type of plant.
Be it construction waste or bulky waste sorting plants, this model example of a young and upcoming class clearly shows how STADLER is keeping up with the times or is already ahead of them.
The material mix of construction materials or bulky waste consists of cardboard, wood, ferrous metals, minerals and films. It exhibits a density of approximately 250 to 350 kg/m³.
STADLER developed high-throughput wood sorting plants to facilitate recycling as much waste wood as possible the first of several plants to be installed in 2012. The objective: to separate all materials that pose a problem to processing.
STADLER is also leading the way with pioneering solutions for waste wood sorting plants. The objective: the maximum possible purity, as is the norm with STADLER.
The input materials of these STADLER sorting plants comprise all types of waste wood, which contain iron elements such as bolts, nails and fasteners, as well as glass or other impurities.
The performance and efficiency of each sorting system is fully dependent on the performance of the individual components installed.
Whether our particularly robust ballistic separators, torsion-resistant trommel screens made of 10 mm-thick Hardox steel, innovative STADLER conveyors or our new high-performance label remover. STADLER components stand for premium quality Made in Germany.
Intelligent solutions, a particularly solid design and a consistently high level of serviceability as well as a wealth of experience from over 3,000 individual components delivered. This is what our customers all over the world rely on.
The ballistic separator STT2000 is specially designed for sorting the following feed materials:
The PPK200 ballistic separator is specially designed for separating paper, OCC and cardboard without 3D fractions
The STT5000 ballistic separator is our all-rounder for separating household waste, mixed commercial waste and bulky waste.
Thanks to generously sized material outlets and completely smooth contours in the screen outlet, the STT6000 can sort individual particles that are up to two metres long.
The use of 10-mm Hardox steel results in robust and incredibly strong, torsion-resistant trommel screens. What is more, the drive, support and guide wheels feature double bearings for extremely low-vibration operation.
Reliable break-up of material compounds. Even distribution of the materials being sorted. Optimum sizing of materials into different particle sizes. This is what our trommel screens do.
For flows of light to moderately heavy materials and average centre distances, together with compact design.
For flows of moderately heavy to heavy materials and long centre distances with low drive powers at the same time.
The STADLER acceleration conveyor has been specially designed for use with sensor-based sorting technology. Thanks to conveyor speeds that can be precisely controlled, it effectively spreads the flow of material.
The material is accelerated and straightened. As a result, sensors (not included) detect the material on the conveyor and individual particles can be blown out with a nozzle bar (not included)
For material and air control in sortingsystems with compressed air discharge of one or two fractions.
Bush conveyor chains allow flows of even heavy and large materials to be transported with ease.
The side wall and belt position have been specially designed to sort material as efficiently as possible directly on the conveyor.
Developed for temporary storage of sorted material fractions, the STADLER storage conveyor has side walls up to 2.5 metres tall.
The material is evenly distributed and thus ensures a constant feeding of the system and higher purity.
Our powerful label remover processes up to nine tonnes of plastic bottles per hour – achieving a quality standard of up to 80 per cent of labels removed. It features a robust overall construction and is incredibly resistant to impurities.
Equipped with blades made from high-tensile steel that are attached to the rotor at one end so they can oscillate freely, and to the housing’s inner wall at the other, the label remover processes a mass flow of up to nine tons per hour depending on the particle size and material composition.
