Reduction in water consumption

Chemistry is at the heart of the great challenges of our society. It is a science that is resolutely turned towards the future. Reduction of water consumption is a major focus which is at the origin of many innovations. Lamotte industrial Park is engaged in a sustainable industrial development which encourages it to master its consumption and to conserve this resource .

Wastewater treatment plant

The treatment capacity of a city of 300,000 inhabitants

The purification yield reaches values greater than 95%. The performance of the water treatment plant is constantly evolving in order to reduce the impact of industrial activities on the quality of the natural environment. The station also operates in part biological treatment.

Self-monitoring makes it possible to check daily the quality of the water, released into the natural environment after treatment. Hydrobiological expertise, carried out each year during low water periods, confirms the low impact of the platform’s activity on the aquatic environment of the river Aisne, for more than 20 years.

Pretreatment of nickel

Commissioning of a pretreatment of nickel contained in the effluents of a unit of agro-chemical production in 2015.

Biological treatment of acetic acid

Biological treatment of an effluent, acetic acid: this liquid is transformed to Biogas in a digestor, and is then used to produce steam. The digestor of the biogas plant was renovated in 2013.


Of saved energy production

Thanks to the biological treatment of acetic acid.

Sulphate recovery

Since 2012, a processing unit has been able to recover sulphates from a production plant. This facility responds to the capacity of the production unit whilst reducing the impact on the
Natural environment by the crystallization of sodium sulphate. Previously, the annual sulphate flux was 6,440 tonnes.
▪ 60% overall effectiveness of treatment,
▪ Outlets in detergents market,
▪ Absence of waste generation.

Soil protection

Soil protection involves a set of actions systematically implemented on Lamotte Industrial Park.

Preventative measures

▪ Storage areas installed on retention pits.
▪ Production plants built on retention.
▪ Loading / unloading areas are equipped with systems for collecting rainwater, for treatment in a wastewater treatment plant.
▪ Aerial piping : All the pipes are built on pipe-air racks, including for the transport of effluents to the treatment plant.
▪ Flood compensation basin: Creation of a compensation pool of 8,240 m3 for the retention of water in case of flooding of the Aisne river.

Monitoring measures

▪ Piezometers : 19 piezometers placed on the site to control the quality of groundwater; Two sampling and analysis campaigns per year.


Reduction of greenhouse gases

To combat global warming, an industrial unit for the treatment of N2O emissions was set up in 1997 by a patented catalytic destruction process. Since 1993, the site of Lamotte carried out the first tests to reduce the greenhouse gases generated by the production units of glyoxal and glyoxylic acid.
The performance and capacity of the N2O processing unit has been consistently improved to achieve a performance of over 95%.
The global warming effect of nitrous oxide N2O is 298 times higher than that of carbon dioxide.


Of N2O emission avoided

Since 2005

Reduction of acidifying gases

Based on experience in the treatment of N2O, the platform has invested in the catalytic treatment of nitrogen oxides. With this new processing unit, NOx emissions have been reduced by 80% since 2005.

Energy & Transport

Energy production and consumption

Energy management groups together the notions of production and energy consumption. Positive cycle of sustainable material development means, for an industrial site, the self-production of a part of its energy and the reduction of its energy consumption.
Several projects have been carried out or are in progress:
heat pump installation,
self-production of half of the steam used on the site,
optimization of energy consumption.

ISO 50001

Transport of materials

In order to limit industrial risks, material storage is maximized. This is why large-capacity transport, such as the barges of 250 tons,; As well as dedicated rail shuttles connected with national rail network. Materials of low tonnage are transported daily by trucks. One of the objectives of sustainable development is to reduce the traffic of certain products by gaining more autonomy in production cycles.

80 trucks by day

(Up to 2 000 tonnes)

1 train by day

(Up to 960 tonnes)

1 barge every 15 days

(250 tonnes)
