The deposit system in Poland has ceased to be a concept and has become a reality. Every day we return bottles and cans, stores handle return points, and reverse vending machines have become part of the urban landscape. However, the real effectiveness of the system does not end with collection.
The key question is what happens to the packaging after it is returned.
The true effectiveness of this system does not result solely from the level of collection of packaging, but from what happens to it in the later stages. It is behind the scenes, in sorting facilities and processing plants, that it is decided whether the deposit system actually meets its environmental and economic goals.
The invisible stage that determines everything
After packaging is returned in a store or a reverse vending machine, its logistical journey begins, leading to sorting centers. There, modern technologies play a key role, making it possible to quickly and precisely separate individual materials. Without this stage, even the best-functioning collection system loses its effectiveness, which is why optical sorting technologies are becoming the foundation of the entire system.
One of the solutions addressing these needs is the Meyer KC object sorter, designed specifically to handle large streams of packaging generated by the deposit system. Thanks to the use of optical cameras and advanced image analysis software, the machine identifies not only the type of material, but also its color, structure, and distinctive features. The KC makes it possible to quickly separate materials in a way that only a few years ago was practically unachievable using manual methods.
The essence of this type of equipment is not only accuracy, but also speed. The deposit system generates volumes that require continuous operation, without downtime and without any loss in separation quality. The bottle sorter by Meyer has been designed with these conditions in mind: stable operation under heavy load ensures that the sorting facility does not become a bottleneck in the entire process, but rather its most predictable and efficient element.
When details make the difference: integrated Meyer technology in modern sorting
In modern sorting systems, there are no accidental elements. Every component, from cameras and control units to ejection systems, affects the final result. It is the sum of these seemingly small solutions that determines whether a line operates smoothly and efficiently. That is why it is so important to pay attention not only to the overall parameters of a machine, but also to the quality and consistency of the technologies delivered as a complete package. In the case of the Meyer KC, we are dealing with a solution in which software, hardware, and mechanics form one integrated system.
Under this concept of integration, several elements are included:
-
AI Deep Learning:
The use of artificial intelligence based on deep learning models. The system does not operate according to rigid rules, but learns from vast datasets. It simultaneously analyzes multiple features such as shape, color, and characteristic label elements, comparing them with an extensive model database. This makes it possible to identify even very small differences and defects. Importantly from a practical perspective, such a system can recognize not only the type of material, but also specific product patterns. This means, for example, that it is possible to separate bottles of a particular beverage brand regardless of their physical condition. Even if the packaging is crushed, deformed, or dirty, the algorithms are able to identify characteristic features and assign them to the correct category.
-
Stable object transport:
In the Meyer KC bottle sorter, transport solutions have been implemented that are specifically designed for objects such as bottles, which in a deposit system are not always properly compressed and naturally tend to rotate and move in an uncontrolled way. The conveyor belt is equipped with special protrusions that prevent the rotation of the packaging. In practice, this means that each bottle reaches the vision system in a predictable orientation. This directly translates into the effectiveness of detection and ejection. Even the best camera and algorithm will not perform properly if the material behaves chaotically.
-
Maglev ejectors:
Maglev ejectors are responsible for the physical “ejection” of a selected object from the belt at the right moment. What distinguishes them is the way they operate. Instead of a classic mechanism based on standard solenoid valves or the movement of mechanical parts, they use magnetic levitation. This means that the moving element operates without physical friction. In practice, this provides several very specific benefits. First, the ejectors can operate much faster, because nothing slows them down mechanically. Second, they wear out more slowly, because there is no traditional contact between components that would cause abrasion.
-
Compact design:
In the case of the Meyer KC sorter, compactness does not mean compromises, but a deliberate approach to designing the entire system. The machine has been designed to minimize the space it occupies while maintaining the full functionality of all key components. The integration of vision, transport, and ejection systems into one compact structure simplifies implementation and allows the sorter to be better adapted to the existing plant infrastructure, which translates into greater predictability and stability of the entire sorting process.
Where collection ends, real value begins: who wins at the sorting stage
In the context of material processing, optical sorting technology stops being a background element and becomes a factor that defines the purpose of the entire system. Above all, it increases yield and recovery rates, supporting the circular economy. Because the deposit system does not end with the return of packaging. Its real effectiveness becomes visible only when the material goes through a process that can properly identify it, separate it, and prepare it for reuse.
The Polish deposit system is now entering a stage of optimization. It is no longer about whether packaging is being collected, but how efficiently it is processed. Companies that invest in advanced solutions gain a real operational and quality advantage. Object, color, and polymer sorters define the processing of materials such as PET, PP, and PE. It is at this stage that it is decided who will be able to operate faster, more efficiently, and set new standards in the evolving reality of the packaging economy.
