Customised Upgrade According to Your Need
 From open heaps with loader to:
Step 1: Typically Options 1 to 3
Step 2: Typically Options 4 or 5
 From membrane covered system to:
Tunnel / LTC (for intensive phase) and
keep existing system for maturation
Operator wants
 more throughput on
same m²
 better product
 more reliable process
Operator must
 Abide laws and regulation
(enclosed)
 React to pressure from
neighbors
 From open heaps with loader to:
Any membrane covered system
(Options 2 to 4)
 From open windrows with turner to:
Option 3 or 4

6. 6
Open Heap
 Degradation of organic substance by
microorganism
 Temperature regulation by natural venting
and occasional turning
 Humidity regulation by natural irrigation
and where appropriate water addition

7. 7
Option 1 - Open Windrow with BACKHUS Turner
 Natural aeration optimized by regular
turning with windrow turner
 Concrete floor or asphalt (or any existing
hard standing)
 Adding moisture by windrow turner
Compared to loader turned heaps:
a turner improves oxygen supply and reduces process time

8. 8
Option 2 - CONVAERO Mobile Heap
 Membrane covered, pressure aerated,
mobile heap
 Can be installed quickly and efficiently
on nearly any available area => no civil
works required
 As intensive phase with full process
control and safe sanitization
 Turning by wheel loader
 Also for temporary operation (e.g. trials)
or covering seasonal input variations
Compared to open heap and open windrow:
CONVAERO mobile heap is a enclosed system with full process control

9. 9
Option 3a - CONVAERO Bay
 Membrane covered, pressure
aerated, static waste pile in a bay
 Permanent facility & Continuous
operation
 Loader is the only mobile machine
required
 Future proof – flexible to cope with
varying input material
Compared to COVAERO mobile heap:
CONVAERO Bay provides higher capacity, easy operation (in-floor-aeration),
leachate collection included

Option 3b - CONVAERO Windrow with BACKHUS Turner
 Membrane covered, pressure aerated,
semi-dynamic windrow
 Turning by Standard BACKHUS Turner
A45 – A75
 Integrated Turner and cover winder
 Mixing of materials included (e.g.
digestate & green waste)
 Future proof – flexible to cope with
varying input material
Compared to open windrow:
CONVAERO is a covered process with full process control.
Compared to CONVAERO Mobile Heap or Bay – it adds dynamic aspect to the
membrane system.
For both comparisons: higher product quality, shorter process time

11. 11
Option 4 – CONVAERO System with BACKHUS CON
 Membrane covered, pressure aerated,
semi-dynamic lane
 Site operation is almost fully enclosed
despite frequent turning
 Input material with high moisture content
up to 70% can be treated with this
solution.
 Press water, surface water and roof water
from membrane covers can be collected
separately.
 Future proof – flexible to cope with
varying input material
Compared to any of the previous options:
- Semi-automatic operation
- 25% more capacity than windrow with the same footprint & same height.
- Also enclosed during turning

 Closed system
 Controlled, automatically regulated
pressure ventilation
 Controlled, automatic humidification
 Registration and recording of the process
parameters oxygen, temperature, air flow
 Automatic control of the process
parameters via PLC & SCADA system
Option 5 - Closed Tunnel with Pressure Ventilation
Compared to Options 1 to 4
- Fully enclosed system with scrubber & biofilter emission control
- Fully automated operation possible
