Example process description for a fully automatic municipal solid waste sorting plant:
Municipal solid waste consists of all types of waste generated in the household.
In addition to organic waste such as leftover food, this also includes a wide variety of recyclable materials. This type of diverse material composition with
a correspondingly highly varied density of between 100 and 300 kg/m3
represents a particular challenge for such plants, because it simultaneously
demands a high degree of plant flexibility and robustness.
Example process description for an automated sorting plant for municipal solid waste with manual re-sorting:
After infeed dosing, the material is separated into different grain
sizes according to shape (flat [2D], rolling [3D], screening) by various
screening processes via our trommel screen and ballistic separator machinery.
In order to achieve the maximum possible sorting purity, large-area films are
separated from the material flows with the aid of windshifters. This significantly
improves subsequent sorting using near infrared technology . In
combination with the subsequent magnetic and eddy current process, the desired
high output qualities are achieved. Following manual quality controlling,
the material is finally separated into fractions, collected in hopper belts and pressed
to reduce volume for storage and transport.
