WHAT IS COMPOSTING?

  

Composting is a process of fermentation and transformation of organic matter. It relies on the action of microorganisms in an aerobic environment, i.e., in the presence of oxygen. This natural process produces fertile soil:  compost.

Thanks to this method, it is possible recycle bio-waste, particularly that from organic waste treatment platforms . 

This activity generates several types of liquid effluents :

  • the wash water from the receiving tanks
  • compost leachate, resulting from runoff through decomposing waste
  • and runoff water on the platform.
the treatment of effluents from composting platforms



Effluent generation on composting platforms


These effluents are particularly high in in nitrogen pollution (ammoniacal nitrogen and TKN),  carbon pollution (organic waste, COD), phosphorus, and metals.

Without proper treatment, they can:

  • disrupt the bacterial biomass in soils
  • acidify them
  • disrupt the nitrogen and phosphorus cycle.

If they reach waterways or groundwater, these elements promote phenomena such as eutrophication, which seriously harms aquatic biodiversity. .

Treatment solutions


wastewater treatment plant

Solutions that can sometimes be very costly, particularly in terms of transportation or decontamination costs.


agricultural spreading

A more economical solution, but one that is subject to a regulated spreading plan.


on-site treatments

NOur biological treatment solution enables on-site treatment for discharge into the natural environment or for direct recovery and reuse, for example for washing. 

Air biofiltration is a process for treating industrial gaseous effluents.


In this process, a gaseous effluent laden with pollutant molecules is forced through a packing material. A microbial community adapted to the targeted treatment develops and lives around each particle of the packing within a thin film of water called a biofilm. As the effluent passes through the packing, the polluting molecules come into contact with the biofilm under the effect of various physical phenomena (diffusion, absorption, etc.). The microorganisms then break down these molecules to extract the energy they need for life and growth. The air then emerges from the purified packing. This biological process makes it possible to recover bio-waste, which is rich in organic matter.
