Limagrain and Dalkia inaugurated in late June the first installation of steam production from corn cobs in Europe, co-products from the process of Primary Limagne corn grown by farmers, members of the Cooperative.
The contract awarded Dalkia includes the design, construction and operation for 10 years of a biomass boiler 3.5 tons/hour, the main fuel is corn cob.
Transforming energy each year nearly 4,000 tons of corn cobs from its process of seed production subsidiary Limagrain Cereal Ingredients located Ennezat, the agricultural cooperative group should severely limit the use of gas and reduce its carbon footprint more than 2,600 tons of CO2 per year. This will allow the site Ennezat control energy costs of its production process corn flour and intermediate products.
This project represents an investment of 2.4 million euros paid by Limagrain. It received support from the Renewable Heat Fund (ERDF – ADEME), in the Auvergne region and the General Council of Puy Dome for a total of up to 960,000 euros.
Several experiments were needed to assess the feasibility of this first prototype in Europe. The R&D teams of Veolia Environnement, associated with boiler manufacturer In-R worked up complete control of the combustion cycle of the new energy and its environmental impact. Corn cob has a calorific value twice that of wood chips and has unique characteristics in terms of fusibility.
Produced over a period of approximately two months after the maize harvest in September-October, the corn cob will be stored on site.
Limagrain has decided to formalize its approach to Corporate Social Responsibility (CSR) and to continue to operate its innovations term “full cycle.” Consideration is also being given to the application of ash from burning raids.
