Pre-processing of organic waste

Can we remove plastic? Of course we can!!

 

Our ten-year-long experience in the field of MSW (Municipal Solid Waste) has allowed us to develop a machine capable of separating plastics called BESC (Biogas Engineering separator centrifugal).

It is a machine that can handle different types of material from recycling (MSW), food that is out of date, bottled and/or nylon coated in packaging.

Our BESC is designed to collect the organic material particularly suitable as fuel to ensure efficient operation of the biogas plant, with the task of carefully removing any plastic .

 

This machine can only be used with organic materials, mostly from selective waste collections.

 

The main objective of our Separator (BESC) is to obtain pumpable material free from plastic and other materials to supply the digesters.

The system allows the most efficient integration of the process of anaerobic digestion and composting, in particular for MSW and out-of-date food.

 

BESC DESCRIPTION:

The device is equipped with three operating units:

 

The first is a hopper into which the saste is loaded by a mechanical spoon. At the bottom of the hopper is a pair of worm screws which rotate against each other.Their function is to:

  • shred plastic bags;
  • partially dissolve and mix the waste together;
  • Cruch other undesirable material.

 

The second unit consists of a vertically positioned chamber which receives partially crushed waste and further separates it centrifugally. Inside the chamber there is a vertical worm screw, which is encased in a metal grate and rotates at high speed. The metal grate tears the plastic bags to even smaller pieces and the rotation causes the plastic material to be transported upwards, where it falls out and is collected. Organic material, on the contrary, flies horizontally, falls through sieves and accumulates at the bottom.

                                                                                                                                                                                                                                                The last component is the collection tank of the organic fraction, where it is present inside a mixing auger so as to maintain the most homogeneous material can then use it as a power plant material.

Other heavier, undesirable material can be further separated by decanting.

BESC IN OPERATION:

In the video side by side, you can see our car BESC separator during operation in all its phases, from the load of waste with the shovel, the separation of plastic until obtaining the organic fraction, which will later be used as material power for a 1MW biogas plant.
