Center for the preparation of secondary raw materials

The Center for the preparation of secondary raw materials consists of over 150 elements, each of which plays an important role in the separation of mixed municipal waste. Within one year, the Center is able to process almost 40.000 tons of mixed municipal waste in one shift. The surface of the device extends in an area of over 5.000 square meters.

When the truck delivers waste to the Center for the preparation of secondary raw materials, the waste route begins with tearing up all the bags in which the waste was deposited in black containers. Waste then travels to the drum, which sorts the waste into four sizes. This is very important, since large sections could cause disturbances and clogging. They could also cover small material and make sorting more difficult. So efficient and technologically advanced seal drum provides the basic condition that the output fractions are cleaner and of better quality.

Now waste is ready for a real action. Two optical machines eliminate all plastics. This moves forward to two ballistic separators, which classify plastics in size and shape in three fractions. This is extremely important for the efficient operation of optical devices called the NIRs. NIRs are separating waste by means of infrared light. In addition, three iron magnets are provided in our center, two air separators and two turbine circuits that sort colored metals, predominantly aluminum.

Extremely precisely sorted mixed municipal waste is divided into three main groups after completing the journey at the Center for the preparation of secondary raw materials. The ratio of waste to recycling, which is passed on as a light and heavy fraction, makes our Center for the preparation of secondary raw materials so unique in this part of Europe. 77% of collected waste is used for real recycling, 9% of the light fraction is dedicated to energy use, and only 14% of the heavy fraction is disposed. Such results are not reachable at any other center in Slovenia. That is why only our Center for the preparation of secondary raw materials is purely recycling.
