Biological treatment - anaerobic digestion/composting

Biological treatments of organic waste - through aerobic composting units' and anaerobic centers' management - this will prove to be the best approach over time. With more than 100 composting units in the world, Veolia helps to revitalize soil with composts and organic fertilizers and recovers energy through a biological treatment of waste that includes aerobic composting and anaerobic digestion suitable for organic waste disposal.

Veolia’s extensive knowledge and expertise include:

In general, composting treatment is suitable for garden/park waste, straw with low moisture content and other organic waste, while anaerobic digestion treatment is suitable for food and animal waste or any organic waste with higher moisture content. Veolia provides proper organic recycling solutions according to the needs of farmers and local municipal authorities throughout Europe

Veolia composting facilities can recycle the biogas generated by waste during its anaerobic decomposition.

After biological treatment, compost products are sold to farmers, landscapers, public organizations or families to make soil more fertile. Veolia’ composts received 9 European environmentally friendly awards. This reflects the commitment Veolia has to quality, safety and flexibility in the certification and product standards of its composting facilities.

Since 1997, Veolia has been collaborating with the Energy and Cleanliness Research Centre (CRPE) and the National Institute of Agricultural Research (INRA) to conduct studies on the agricultural value of municipal waste compost.
Committed to public health protection, Veolia has also worked with the French Health Insurance Fund (CNAM) and the Environment and Energy Management Agency (ADEME) to ensure the safety of its composting products, which especially targets at pathogens.

Veolia is continually working to reduce and avoid the emission of greenhouse gases. Below are the specific actions taken by Veolia in its composting facilities:

  • Improving compost output and adopting low-emission treatments;
  • Reusing compost in agriculture: avoiding the use of inorganic fertilizers so as to contribute to soil carbon bonding;
  • Recovering the gas produced from the methanization process, generating heat and power.
