Sorting plant for waste from economic activity
Sorting centres for economic waste are flexible and versatile units that adapt to the variety of incoming waste.
Waste concerned: ordinary Industrial Waste (OIW), waste from Economic Activity (WEA), C&D waste.
Very heterogeneous (in particle size and density), this waste consists of large pieces of wood, such as pallets, as well as inert components, such as sand or soil, or even large plastic sheets. Our robust equipment is adapted to the high density of certain materials (concrete, steel).
The main objectives of these sorting lines are to :
- Separate the inert portion: the main composition of the waste flow by weight
- Extract high value-added recoverable materials
- Sort the non-recoverable portion to prepare it as a solid recovered fuel
- Minimize as much as possible the portion of final waste
Method :
The pre-screening is an essential step at the beginning of the unit. It makes it possible for the operators working in sorting compartments to extract the top fraction of the flow, mainly made of recoverable material. A second screening step of the bottom fraction allows isolating the inert fraction of the flow. One more mechanical sorting step can be applied to the inert portion according to the purity requirements. The intermediate portion can finally be mechanically or manually treated, according to the centre objectives.
The use of manual sorting plays an essential role in defining these processes, in order to obtain pure and constant waste flows.
The RMIS added value :
Our simple and robust equipment is adapted to heavy and abrasive materials. We integrate the restrictions related to dust generation from the beginning of the process, in order to reduce its propagation as much as possible.
