SOLID WASTE SORTING PLANTSBACK
The solid waste sorting plants has the ability to sort organic and inorganic materials as household wastes. In addition, it sorts inorganic materials to be recycled and make them ready for a secondary process.
Thanks to the technology of the solid waste sorting plants, a work which can be completed with 100 people in normal conditions can be completed by a 15-people team. The plants which shall be managed from full automatic control room (SCADA) sorts organic and inorganic wastes by a trommel screen.
Afterwards, it separates glass, metal, aluminium, plastic and paper products by ballistic, optical and eddy current separators. These advanced technology separators sort packages by colour, weight, thickness and magnetism. The sorted packaging wastes are made ready to transport the related recycling plants by bail press machines.
The sample plants of which technical properties are explained below entered into service in Bilecik and it sorts 300 tons of household and industrial wastes a day.
The waste rehabilitation unit with fully automatic control system is equipped with high-technology automation and electronic systems, and the control unit providing a detailed view of the entire plant offers single point solutions for failures, emergencies, maintenance and maintenance recommendations and supports the system with the trouble-shooting recommendations and provides maximum efficiency.
This area is the waste admission area of the waste sorting and rehabilitation plant, where some 300-1000 tons of waste per day are brought in from all over the city for sorting and recycling.
The wastes after the tipping floor, start a journey towards sorting and recycling. In the 2nd stage of the operation, the bags are slit in the bag opening machine and the contents are carried to the trommel screen by the conveyor.
The garbage consists of 3 components essentially: the organic wastes, recyclable wastes and wastes with calorific value.
The organic wastes and the other wastes with a recycling potential are separated from each other by the trommel screen. After this operation, the organic wastes are loaded on trucks for sending to the energy and compost production plants. Separation of the organic wastes from the other components, they become ready to use at advanced stages (compost, methane, fertilizer, land reclamation etc.) . The wastes with a potential of recycling are transferred to the optical and ballistic separators for more detailed rehabilitation in the next stage.
In this section, the metals in the waste are separated by magnets before loading on the carrier.
All the plastic materials in the wastes after the first separation in the trommel screen are sorted with optic separators for transferring to the ballistic separator. The remaining mixed waste is transferred to the other optic separators.
The ballistic separator is an essential component of the waste sorting plant. The main purpose of the ballistic separator is separating the 2Dimensional/Light 3Dmensional/heavy waste fractions from each other to ensure high separation efficiency in the further processes. Benli Recycling Group manufactures the ballistic separator, for which “know-how” transfer was made from Europe, in Turkey.
The sorting of the 2 Dimensional materials progresses with the same logic as in the 3 dimensional materials; the optic separators are programmed to detect the 2 dimensional materials. The bags, plastics, etc. products are detected with excellent accuracy and sent to the conveyors automatically.

In this section, the Non-Ferrous aluminium type of materials are detected by the eddy current sensor separators and sent to the aluminium conveyor band and then to the appropriate bunker.
In the next stage, the 3 dimensional products separated by the ballistic separator by the PE, PP plastics in the first phase using a single optic separator and by the PET plastics by loading the line again in the 2nd phase automatically. The optic separator carries out the sorting operation with a high speed of 3.5 meters per second, which means a 20 times faster operation as compared to separation by an operator.
All the components sorted are stored in the special bunkers to be transferred to the bale press at the appropriate times.
