“…The second step is the setting of the size and shape. Typical size setting machines are the drum screens [15] and fine shredders [16], while the typical shape setting machines are the ballistic separators [17] and different air separators [18]. The order of the machines in this step is arbitrary according to the goal.…”

One of the significant problems in our society is the handling and processing of the vast amount of waste produced by households and industrial processes. Nowadays, packaging material regulations are constantly changing, which can significantly impact the quality of municipal waste, requiring the continuous development and redesign of waste processing plants. Since only a few uncertain measurements (composition, mass, etc.) are available for this task, analysing and redesigning waste processing technologies is challenging. This research aims to develop a modelling and simulation concept that can integrate all the available information and can also handle the uncertainty of the measurements. The proposed modular modelling framework can serve as a basis for designing and redesigning the technologies needed to process ever-changing municipal waste. The most important steps of the framework are as follows: identifying the typical equipment, these are the elements; building models of the elements; determining the characteristic parameters of the equipment; exploring the possible relationships between the elements. For example, the information needed to define the model parameters can be gathered from measurements, industrial experience, and expert knowledge. In many cases, the data obtained represent ranges. The stationary model framework applies efficiency factors and divides the solids into substreams based on expert knowledge. Furthermore, a modular simulator framework was developed to simulate the technological schemes with various connections. The specifications for all widely used waste industrial equipment (shredders, air separators, sieves, magnetic-, eddy current-, optical-, and ballistic separators) were used to construct the developed simulator. This simulator can open new opportunities for the design of waste sorting technological networks. The model was calibrated based on expertise gained from operating the studied technology. The changes in the material parameters can be considered, and the modular simulator can lead to flexible waste sorting technologies capable of adapting to governmental and environmental regulations changes. The main result of the work is that a methodology for designing a modular simulator, model development, and a validation method has been proposed, which provides the possibility to deal with uncertainty. All this is successfully presented through the analysis of an operating waste separation system.

“…Only by emphasizing comprehensive control, source reduction and comprehensive utilization, by advocating classified collection and classification processing, by encouraging waste recycling and biological treatment and resource utilization on the organic materials, can the pollution control and resource recycling be effectively realized to achieve the sustainable development of environment and resources. Therefore, it is very meaningful to develop energy-saving and environmental protection equipment with China's actual conditions, low investment, easy operation, good performance and low energy consumption [1][2][3][4][5] . Inertial-type counter flow screen originated from China is a kind of sorting equipment to separate solid wastes by friction [6][7][8][9][10] .…”

The structure of inertial-type counter flow screen is presented in this paper. It can be proved that the solid wastes with different friction factors and elasticity coefficients can be well separated by inertial-type counter flow screen. The more difference they have in friction factors and elasticity coefficients, the better sorting performance can be achieved. The selection and calculation on the dynamical parameters of inertial-type counter flow screen is carried out. The study provides the theory basis for the design on new-type friction separation equipment and develops new prospects for the application of inertial-type counter flow screen.

“…Municipal solid wastes such as plastic bags and pieces of broken plastic film create so-called white pollution in many cities. Although a large number of new technologies have been developed for the harmless and resource processing on solid wastes, the capacity of treatment is relatively small and far below the amount of garbage generated [5,6]. Solid wastes separation sieve, originated from China, is a kind of sorting equipment to separate solid wastes by friction [7][8][9][10][11].…”

The paper presents the structural characteristics of solid wastes separation sieve. Pieces of plastic film and sandstones with different friction factors and elasticity coefficients are chosen as the research objects. The motion and the separation mechanism of materials in the sorting process are studied. According to the motion analysis on pieces of plastic film and sandstones on solid wastes separation sieve, it can be concluded that the materials with different friction factors and elasticity coefficients can all be sorted by solid wastes separation sieve. The more difference they have in friction factors and elasticity coefficients, the better separation performance can be achieved. The selection and calculation on the kinetic parameters of solid wastes separation sieve is carried out, which provides the theory evidence for the design of new friction sorting equipment and opens up new prospects for the application of solid wastes separation sieve.
