Domestic Waste Processing

INPUT: domestic waste

OUTPUT: shredded material < 300 mm (11'8'')

Domestic waste comprises solid wastes which accrue during the normal houskeeping in private households and which are collected by the refuse collection service. Domestic waste is a part of municipal solid waste besides bulky waste, garden and construction waste.

Up to 50 % of the domestic waste in major towns and cities is not disposed off correctly. Therefore there is a large quantity of valuable materials in the residual waste, which would not be used but ends up in the waste incineration. If this waste passes through a sorting process, these resources can be utilized.

PLANT EXAMPLE

Input material: domestic waste
Throughput: 20 – 50 t/h
Output size: < 300 mm (11'8'')
Utilization output: thermal utilization, recycling

PROCESS DESCRIPTION (example)

The input material is charged into theshredder DW 3060 by wheel loader or excavator. During this step, a first pre-sorting is carried out and large contaminants such as metal and rocks can be sorted out.

The DW 3060 can be equipped with an optional comb extension, which ensures a consistant shredding. After the shredding, iron parts are separated by means of an overband magnet.

By means of the screen SM 518 or SM 620, the coarse and the fine fraction of the shredded material are separated. An optional windsifter could be installed above the coarse fraction.
