THE EARLY BEGINNINGS

How Everything Started …

• Jean Vandewalle, a Chemical Engineer founded

BIC Systems NV (BIC BE) in 1972.

• The initial systems:

Moving grate incinerator for Municipal Waste Incineration.

Rotary kiln systems for silver recovery

• The business eventually expanded into other areas:

Medical Waste

Hazardous Waste Incineration.

• Also operated and maintained a 10 TPD incinerator for Medical Waste &

Hazardous Waste in Mouscron, Belgium for more than 10 years.

• Customer base grew, starting from Europe to Eastern Europe, Middle East

and now to Asia.

DRY SCRUBBING SYSTEM

WET SCRUBBING SYSTEM

Key differences between a Dry and a Wet Scrubbing system:

a. The Wet Scrubber can treat the Chlorine in waste up to 30%, whereas

the Dry Scrubber can only treat Chlorine in the waste up to 2%.

b. The Wet Scrubber can cool the flue gas to 200°C directly. The Dry

Scrubber requires a Cooling system to achieve the same.

c. The Wet Scrubber requires ancillary systems e.g. water treatment plant.

1. Rotary Kiln System includes, feeding system, rotary kiln incinerator, post combustion chambers, fan and stack.

2. Dry (D) scrubber systems include the a flue gas cooling system. Wet (W) scrubber systems will require a water treatment plant.

3. Boiler systems require demineralized water treatment plant (demin plant).

4. External reactors are clients’ plants that require the use of steam.
