The most environmentally friendly casting facility in the world
 
  Marmite has recently installed a completely new purification facility at the Poznan factory. The procedure includes activated carbon and catalytic converters, effectively reducing all discharges of acetone, styrene etcetera by 98%.
   
  The facility is made out of two parts:
   
  - A cleaning unit with two adsorption filters equipped with a main fan.
   
  - A destruction unit with a catalytic converter, heat exchanger,
  startup heater and a fan.
   
   
   
   
   
   
  The purification process uses adsorption to clean the VOC laden air. The process air is then purified as it passes through the adsorption filter with activated carbon.
   
  The adsorption filter acts effectively as a concentration device, collecting the solvent vapours over a period of time. The concentrated vapours are released over a shorter period of time, destroyed by oxidation, and the oxidized gases are then used to regenerate the filter. This system allows for great variations in the process air flow and in the concentrations of solvents in the air.
   
  The adsorptive capacity of the filter, once full, is restored by the desorption of the solvents, using hot gases leaving the oxidation unit. The desorption stage is carefully controlled, so as to achieved the most favourable conditions in the oxidizer.
   
  The purification system is effectively self-sufficient in energy content of the solvents adsorbed in the filter. A uniform concentration of solvents in the feed line to the oxidizer, and a constant temperature in the gases leaving it, ensure a high operating efficiency, together with safe and economical operation. This uniformity is an important feature of the system, and results in an optimal design of the oxidation unit.

  Recycling
 
  Cast Marble - a material well suited for recycling.
   
  The components used to create our products do not lose their basic properties when the casting process is over. This means that a finished basin, for instance, which becomes subject to cracks or other flaws can easily be recycled in the process in order to extract raw material. The raw material is then added as filler in the creation of new basins.
   
  Broken or used products can also be sent back to our factory for recycling.
   
  To accomplish this, we have invested in a modern, large mill which grinds the material to coarse dust. The dust is then added as filler in the production of new cast marble.
