CONSTRUCTION WASTE PROCESS DESCRIPTION

Doppstadt, a family-run company

based in Velbert (near Düsseldorf), was

founded in 1965. Initially a producer of

agricultural machines, Doppstadt has

become a leading global supplier of

solutions and services in all areas of

recycling/environmental technology

and resource recovery.

‘Best Solutions. Smart Recycling.’ True to

this motto, we combine proven pro-

cesses technology into individual solu-

tions that are hallmarked by innovative

process flows, maximum operational

efficiency and cost-effectiveness.

In the area of water-based separation

and wet recycling systems in particu-

lar, we provide our customers with

flexible, tailor-made solutions for all

requirements. With sites in Velbert,

Wülfrath, Calbe and Wilsdruff, we serve

customers in more than 40 countries

through our own dealership network and

offer a wide range of services to support

the unique Doppstadt product portfolio.

a wind sifter. These can then be burned

for energy recovery. The heavy fraction

is transferred from the wind sifter to the

sink–float separation system, where it

undergoes further density separation

using the density of water.

The heavy stones and metal parts are

discharged and can be further separa-

ted by magnets. The light pieces of wood

and plastic are washed and can then be

The process of treating construction

waste consists of a screening machine,

wind sifter, sink–float separation and

water treatment.

The screening machine serves to sepa-

rate the fine particle fraction and there-

by reduces the amount of sludge pro-

duced later in the process. The oversize

is further separated according to density.

First, foils are removed with the help of

burned for energy recovery in a similar

way to the foil fraction. For continuous

operation of the sink–float separation

system, a lamella separator is needed to

treat the process water for recirculation.

Here the sediments have time to settle

down, without the need of a big settling

basin, which would take up a lot of space.

Mixed construction waste cannot be disposed on landfill because of its organic com-

ponents. Thermal disposal on the other hand is too expensive. That’s why it should

first be separated according to density so that inert waste can be dumped and com-

bustible material can be burned for energy recovery.

REFUSE-DERIVED FUELS (foils, see image top left)

PLASTIC AND WOOD TO BE BURNED FOR ENERGY RECOVERY (light fraction, see

image top centre)

STONES AND METALS (heavy fraction, see image top right)

All fractions listed here are also free from surface contamination such as fine sand,

plaster or wood dust.

CONSTRUCTION WASTE PROCESS OVERVIEW

TREATMENT OF CONSTRUCTION WASTEPROCESS OVERVIEW

SCREENING The fine fraction is separated from the input to prevent too much dust forming in the wind sifter and too much sludge in the HDS-M.

WIND SIFTING The foils are separated from the heavy fraction and are taken to a container or discharge conveyor. The heavy fraction is handed over to the HDS-M via the side conveyor to undergo sink–float separation.

PROCESS DIAGRAM

WATER TREATMENT Water treatment guarantees continuous operation and consistent separation. Depending on the material, a dosing station may also be necessary along with the lamella separator.

SINK–FLOAT SEPARATION The HDS-M separates the stones from the wood using their different densi-ties. Additionally, the wood fraction is cleaned of surface contaminants, for instance sand, in a washing drum.
