Environment | Our approach to sustainability


Aim for zero environmental impact

Adisseo is pursuing its reduction policy for the impact of its activities on the environment and has set ambitious new environmental objectives. With these first public engagements, the company will contribute to the Sustainable Development Goals set in September 2015 by the UN’s 193 member states.



Strong growth in activity

The activity index illustrates the development of the quantities produced in Commentry, Roches Roussillon, Burgos and Nanjing. Activity remained high in 2018. Several investments to increase the capacity of our European facilities were made at the end of 2018. This should be considered in light of the controlled and improved environmental results for several facilities.


Material consumption is directly related to the slightly higher rate of activity in 2018.


Good control of water consumption. Particular attention paid to loss of drinking water due to leakage, leading to further reduction in responsible consumption.



A new water treatment plant

The construction of the new waste water treatment plant, “O’disseo”, on the Commentry site (France) has begun. This facility will help reduce odour emissions and meet new environmental norms in 2021. It is a new step towards the “Zero Odour” objective which Adisseo has set itself.

The infrastructure will have the latest technology in terms of water treatment. Ultimately, it will process 5500 m3 of water per day, with a possibility of rising up to 7000 m3. With a greater capacity than the current plant, it will help meet future needs.

The budget for the project amounts to EUR 19.3 million, including EUR 4.3 million subsidised by the L’Agence de l’Eau Loire-Bretagne, and it will begin operations in July 2020. Veolia, a company specialised in water treatment, will be responsible for running this new facility.


Sustainable transport

During the Sustainable Development Week, Adisseo Roches-Roussillon (France) won two awards for its Green&Blue approach and its initiatives in terms of multimodal transport.

In this regard, a transport charter is now being applied by all companies on the industrial platform and their transporters.

Transport is a major concern to meet global sustainable development goals. Hence, Adisseo is doing everything in its power to reduce road risk, minimise environmental impact and secure supply and shipment flows.

CERN acquires electric vehicles

This year, the Centre of Expertise and Research in Nutrition (CERN) acquired a second electric vehicle. Management on site has asserted its desire to drop combustion engine vehicles and to contribute to the goal which Adisseo set, of reducing greenhouse gas emissions by 20% by 2025.


Greenhouse gas emissions (the sum of direct and indirect emissions) have significantly decreased in the last few years despite a high rate of activity. This is the result of various energy-saving actions carried out in all our industrial facilities, as well as several structuring investments (example of steam being supplied by a biomass plant in Commentry, in Allier, France).

New supply flows to remain competitive

In a changing international market, Adisseo had to adapt its supply chain and supply flows while endeavouring to limit the impact of our carbon footprint.

In order to deal with the recent hardening of the US trade policy with an increase in custom duties on products imported from China, Adisseo has had to change its flows and logistics chain accordingly for the industrial sites in Burgos and Nanjing.


From now on, flows from China towards the USA have been redirected, favouring supply via Europe. One of Adisseo’s objectives was to ensure that the impact on the carbon footprint was minimized.

Reduction of our atmospheric emissions in China

Adisseo’s site in Nanjing has invested more than EUR 3.5 million in implementing an electrostatic filter to help reduce the dust content of smoke.


NOx (nitrogen oxides) emissions have improved remarkably in 2018 with the use of ammonia injection at the level of the gaseous effluents treatment process thermal oxyder (PTO) on the Roussillon site (France) and improvement actions in the other industrial facilities. SOx (sulphur oxides) emissions have returned to safe levels after an increase in 2017 relating to a more significant use of safety torches on the Saint-Clair-du-Rhône site (France) mainly due to several sudden power losses on the whole site.

“Zero Odour”

 Since 2016, Adisseo has launched a “Zero Odour” project on its production sites. The objective: reducing possible odour nuisance for the local population. The most exposed areas were identified thanks to the mapping of odour-generating sources, and specific actions have been defined.

In 2018, the Nanjing platform implemented the Antares project. This EUR 3.5 million investment is intended to reduce the organic sulphur content of ammonium sulphate, which improves the quality of the end product and reduces the odour impact in the final stages of manufacturing.

That same year, the Roussillon plant redirected one of its major odorous flows, which was previously released into the atmosphere, towards the unit’s gaseous effluents’ treatment process thermal oxyder. Several sources of odour-generating wastewater have been identified and channelled through culverts instead of simple gutters.

Adisseo takes part in the “Solvay Way” Days

During the “Solvay Way 2018” Days which focused on the theme “Safety, Sustainable Development, Mobility and Quality of Life at Work”, two employees in our Cinachem and Cinatech laboratories held a booth which introduced Adisseo’s approach and commitment to “odour management”. They introduced our actions on the industrial sites and in laboratories and presented ongoing projects and good practices using mini-games.

Our first participation to this event was greatly appreciated and visitors were impressed by all the actions we have carried out as well as our knowledge of the topic.

Enhanced panache

For its sustainable development policy and in order to meet important local residents requests, the Burgos plant has invested EUR 500,000 in a new 50-meters high chimney to replace the old 27-meters high one. This new installation in the SOtreatment unit helps avoid fog and frost phenomena for the site’s neighbouring residents. This effective action was recognised by the locals themselves.


(thousand metric tons)

Generally there has been a slight improvement in the total quantity of waste generated by our activity, enabled by the various control actions we have undertaken on the reliability and performance of our units as well as on our waste water treatment plants.


A significant decrease in the overall quantity of our aqueous discharges in the context of a high activity rate. Improvement plans are being developed, in particular to increase the performance of our treatment plants and thus reduce the various components of aqueous discharges.

Adisseo strengthens its commitment in favour of renewable energy

After having secured its supply of bio-mass-based steam for its French plant in Commentry, Adisseo has reasserted its commitment to sustainable growth, renewable energy and the reduction of greenhouse gas emissions with another project in Spain.

The Adisseo Group signed an electricity supply contract with French electricity supplier Engie for its Burgos plant in Spain, 100% based on renewable energy (solar and wind). Operational in 2020, this agreement has been signed for a period of 10 years.

Thanks to this agreement, Adisseo Burgos will contribute to the development of renewable energy in Spain and will be able to incorporate this in its goal of the reduction of CO2 emissions.


Our overall direct energy consumption is directly related to our rate of activity and is monitored thanks to improvements aiming to reduce said consumption (optimisation of natural combustion gas consumption in particular and energy recovery, etc.). The implementation of a biomass plant on the Commentry site (Allier, France) increases the share of primary indirect energy which is bought while reducing the share of primary indirect energy produced.
