Organic waste recovery challenge
Get the best from waste organic components and methanogenic value.
1) Turning organics into a source of green energy
With its high methanogenic value, organic waste can significantly contribute to green energy production (heat, electricity or gas-to-grid) thanks to Anaerobic Digestion technologies.
2) Restoring natural capital as soil fertilizer
Applying compost on top-soil is one of the best solution to revitalize soils. Compost reduces the need for chemical fertilizers, promotes higher yields of agricultural crops and can help reforestation, wetlands restoration, and habitat revitalization efforts.
3) Positively impacting climate change
Compost contributes to carbon sequestration. According to the 4 per 1,000 initiative, an annual growth rate of 0.4% in the soil carbon stocks would halt the increase in the CO2 concentration in the atmosphere related to human activities.
Veolia's solutions for organic waste recovery
Reliable services to local authorities, retailers, hotels, restaurants and F&B industrials that ensure full environmental performance.
Dedicated solutions for organic waste recovery
Veolia has developed an extended expertise on all biological treatment technologies and recovers over 3 million tons of organic waste each year.
Biological process that transforms, in the absence of oxygen, organic matter into biogas (rich in methane and CO2), and into a solid or pasty residue, called digestate. Rich in non- degraded organics and minerals, the digestate can undergo another stage of treatment, depending on local regulations, to be recovered.
This is a continuous process.
Physical and biological process which allows washing (leaching) of soluble organic matter contained in the waste by recirculation of leachate. This process operates in batch. At the end of the process, solid matter can be treated by composting or biodrying, depending on the expected final recovery (compost or SRF respectively). The liquid fraction will be treated by wet AD.
Physical process that removes humidity from biodegradable waste, by ventilation (that may be heated), to produce a Solid Recovered Fuel (SRF) which will be recovered as energy.
Biological process that transforms, with the presence of oxygen, the organic matter into a stabilized and sanitized product, rich in humic compounds, called compost. This reaction generates heat and CO2. Compost is an organic soil fertilizer.

• 170 Nm3/h of biomethane
• 16,000 m3 of liquide digestate per year
Territorial Anaerobic Digestion
SAS Meetha, located in Soudan (western France),is a solution to treat the 20,000 tonnes of organic waste coming from agriculture (manure, slurries, cereal waste,...) and food industry by-products (whey, glycerin, organic waste, green waste,...)
Developed in collaboration with a farmer, the site is a local response to recover organic waste into biogas through Anaerobic Digestion. As from September 2019, the biomethane is directly injected in the gas grid.
The digestate is then spread on nearby agricultural fields for a quick assimilation by the soil and the plants.
The site is a great example of circular economy including local farmers all along the process with a territorial approach.
• 40,000tpa wet-AD process
Based in Northern Germany, the wet Anaerobic Digestion (AD) facility offers a recovery solution for nearby municipalities, retailers and Food & Beverages industries.
Due to the large scope of organic waste, a 40,000tpa wet-AD process was implemented along with depackaging units to best fit with incoming waste streams.
The 600-800 Nm3 per hour of biogas, with high methane content, are converted into electricity supplied to the national grid thanks to Combined Heat and Power (CHP) engines. The digestate is used as a liquid fertiliser for agricultural amendments, meeting the German standards.
• Food waste wet AD to produce 4,900 MWh of electricity per year
EarthPower is Australia’s first food Anaerobic Digestion (AD) facility designed and licensed to accept solid and liquid food biomass from municipal, commercial and industrial sectors in the Sydney region. The facility processes food waste to produce green electricity and a nutrient-rich-by-product fertiliser for the agriculture and horticultural markets.
EarthPower can receive up to 50,000 tons of food waste per year and is able to produce enough green electricity to power over 3,600 homes. Waste heat from the cogeneration engines is used in the fertiliser drying process and also to heat the digesters.
• 25,000tpa optimized aerobic biological treatment of green and organic waste
The small size composting platform in Parcé-sur-Sarthe faced the challenge of treating larger volumes with no additional surface.
Veolia developed and implemented AEROcontrolTM, an innovation based on taylor-made composting windrow aeration system and an algorithm designed to control the aeration according to compost temperature.
The system measures the compost temperature in different windrow spots and adapts the amount of air to be blown under each windrow to optimize biological degradation conditions.
This innovation makes organic material composting more efficient, quicker and easier to manage.
