Sustainable development

Positive industry

As a major industrial player active in numerous sectors around the world, reducing our environmental impact and harnessing the potential of our raw materials are among our most important responsibilities. This is why we have decided to place the circular economy at the heart of our practices, to ensure that our plant waste is recycled as new resources.

The continuous improvement process in which Tereos is engaged is based on two priorities: reducing our water and energy consumption, and developing new ways of recycling non-food waste in our facilities. To achieve these aims, we place the circular economy at the heart of our actions as we strive to develop a model of positive industry.

The rationale of the circular economy allows us to limit our environmental impact by reducing our greenhouse gas emissions and increasing our use of renewables, while improving our industrial and commercial performance.

The Group’s commitments include cutting down on water consumption, improved recycling and recovery of fibre and protein residues for use as animal nutrition.


“Albioma and Tereos have been working together for more than 20 years on energy transition in Reunion Island. Excellent cooperation between the teams at the Bois-Rouge and Le Gol sugar factories and those of our power plants results in exceptional conditions of efficiency for the conversion of the bagasse produced by Tereos. We have been able to achieve a ratio of around 120 kWh of electricity per of tonne of sugar cane milled, which is one of the highest in the world.”

Examples of actions supporting positive industry

Tereos and Nigay caramels focus on industrial synergies

A parcel of the Tereos Nesle site has been transferred to Nigay, a caramel specialist, which directly links the Nigay Group production site to the Nesle Tereos plant for glucose supply and utilities use. They are sharing this production unit at the heart of the agricultural raw materials processing basin is needed for the production of Nigay products: sucrose extracted from beet and glucose syrups derived from wheat starch and corn starch. Nigay plant directly into glucose by a “pipe” connecting the two sites, without generating transport. Tereos also processes the effluents from the plant. These synergies make it possible to optimize water treatment and flows. Logistics is also important for finished products. The potential of the Nesle fluvial port makes it possible to ship containers through multimodal transport, a mode of transport practiced for many years to reduce the carbon footprint.

A virtuous circuit of the use of water

A beet contains 75% water. It is in volume the first production of a candy! Tereos has been working for a long time to make the most of this natural resource in its factories. The water extracted from the beet is stored in basins before being reintroduced into the transformation process. Part of this water rich in nutrients will also irrigate the cultivated land near the sugar factories. This is the principle of fertirrigation (fertilization and irrigation). Five Tereos sites, including the Boiry sugar refinery, use this technique, which brings a double benefit to farmers. It prevents them from drawing in the natural environment and brings to the cultures elements rich in minerals.

Waste: nothing is lost everything is transformed

Waste recovery is a strong commitment at Tereos, which has placed the circular economy at the heart of its production and processing of raw materials. In 2017, Tereos, Nestlé and the Bonduelle Group joined forces in an industrial group to supply agricultural raw materials for the Group’s new biogas plant in the Somme region. This is the opportunity for Tereos to valorize its beet residues in the form of biogas or agricultural spreading, distributed on the lands of the 30 farmers participating in this project.
