Biowaste consists of biodegradable organic materials:
- Fermentable and organic waste generated by households, restaurants, the retail and agribusinesses as well as agriculture.
- Green waste.
- Sludge from sewage plants.
Since 1 January 2012, large producers of bio-waste must organise sorting at source, energy-from-waste or biological recovery of organic waste.
In order to respect the objectives of the Grenelle Forum on the Environment, SITA creates compost from its clients’ organic waste:
- Optimising the collection and pre-treatment of bio-waste by biopackaging (separating the packaging from the recyclable materials by composting).
- Biological recovery : SITA handles the transformation of biowaste into natural fertilisers and compost.
- Energy-from-waste recovery : the biogas produced from the breakdown of waste is collected and transformed into renewable energy.

88 SITA compost facilities in France
- Néoval : 50,000 tonnes of household and similar waste treated.
Thanks to special sorting techniques, the new mechanical-biological (MBT) recycling facility located in Salindre facilitates the isolation of recyclable materials from household waste (which should have been in selective collections) and the biodegradable waste, which becomes compost.
Néoval offers an efficient solution suited to environmental needs to develop:
- the recovery of recyclable materials in waste
- the organic recovery of food waste and the generation of compost
- energy-from-waste recovery of waste with a high calorific value (PCI)

- YELLOWBIO : recovering food oils
YELLOWBIO® is a SITA service which has the role of transforming used food oils from the catering and food processing industries into recyclable biofuels destined for industrial combustion plants to generate heat and electricity.
In partnership with SMICVAL (intercommunal household waste treatment and recycling syndicate in the Libournais Haute-Gironde region), SITA has organised new collection drums for food oils in the 12 recycling centres. Equipped with new funnel lids, these drums guarantee ergonomic design and hygiene, and allow individuals to pour all their used food oils in the drums. The oils are then treated and transformed.
- Valorest : Managing biowaste in a military camp in Haguenau
The Estienne quarter of the army has been setting up initiatives to encourage sustainable development for years, such as sorting cardboard and paper.
They wanted to go even further and became interested in bio-waste.
SITA created the first biopacker in France, Valorest. Its process makes it possible to separate bio-waste from packaging in order to produce two types of waste recovery. The bio-waste is sent to a recovery channel for anaerobic digestion and the packaging is recovered by incineration.
Committed to improving its kitchen waste management, the army participated in tests for six months before the creation of the biopacker.
After an audit of the army camp, SITA offered the best solution, factoring in the site, the space available and the organisation of the facility by providing eight 240-litre tanks and collection twice a week. Kitchen personnel went through specialised training for sorting waste. The training was then offered to military personnel eating on site.
Furthermore, SITA offers to track the tonnage of bio-waste, the quality of waste sorting and treatment as well as the waste transmission.
