Energy

Recovering agricultural and industrial waste is essential to provide a sustainable and cost-effective replacement for a portion of fossil-based raw materials. By maximising the recovery of agricultural products, we ensure that products and ingredients are competitive for Tereos’ customers and for consumers.

Challenges

Focusing of our actions on the circular economy and the regions, developing new ways of recovering non-food waste in our plants and preserving natural resources to the greatest extent possible.

Goals

  • Promoting green energy derived from our raw materials as a replacement for fossil energies (gas, oil, etc).
  • Improving the value of agricultural production by creating value from by-products and waste.
  • Increasing our energy efficiency and reducing our carbon footprint.
  • Integrating our biorefineries in their regions.

Strengths

Examples of applications

Half of the energy used by Tereos plants comes from renewable sources.

Reducing our gas consumption

In March 2021, Tereos and SUEZ announced a partnership project to reduce gas consumption at the Origny-Sainte-Benoite sugar plant in France. This project is based on SUEZ supplying renewable energy and energy recovered as steam, which is produced from solid recovered fuels (SRF). This boiler will cover almost 40% of the plant’s energy needs.

Using digesters to produce biogas

Vinasse is a by-product of the production of alcohol from sugar beets. By transforming it into biogas using digesters, we can reduce our consumption of fossil energy and our CO2 emissions. At our facilities in Artenay, France, and Dobrovice, Czech Republic, our two methanisation units enable us to cover over 50% of energy needs during the campaign. This is a world first for Tereos research.

Cogeneration: a growing source of electricity

In Brazil, Mozambique and Reunion Island, where we process sugar cane, our plants are self-sufficient in energy thanks to the green electricity produced from bagasse, the fibrous residue of crushed sugar cane. It is burned in high-yield boilers and provides electricity for our facilities. Excess power can be fed into the public grid. 12% of Reunion Island’s annual electricity consumption is produced by this process, which also provides power for the two Tereos facilities. In Brazil, Tereos supplies the public grid with the equivalent of the annual power consumption of a city of roughly 1.3 million inhabitants.
