Energy is one of the important flows of the circular economy. ENGIE is therefore at the heart of possible solutions for the preservation of resources, the reuse of energy such as biomethane production or heat recovery.

The diagram below illustrates the place of energy in the loop of the circular economy.

The commitments of the Group

On 1 February 2017, under the coordination of the AFEP (the French Association of Private Enterprises), the ENGIE Group, along with 32 other French companies, has undertaken three engagements to develop the circular economy:

    • Boosting renewable gases: biogas, first, second and third generation biomethane
    • Develop energy recovery on industrial and tertiary processes
    • Tooling innovatively to help decision-making process relating to circular economy in industrial zone

    The circular economy in action

    BE CIRCLE, innovative nature


    BE CIRCLE has been developed within a European collaborative project as a service for industrial companies and their ecosystem. It aims to facilitate their transition to a circular economy.

    Based on a modelling platform, the tool aims to:

    • develop synergies between businesses to save resources and make economic gains
    • decarbonize industrial activities
    • optimize the footprint

    ENGIE Biogaz

    ENGIE Biogaz

    Through ENGIE Biogaz, ENGIE Cofely offers an upgrading offer for biogas produced by scrubbing and injecting biomethane into the networks. This makes it possible to favor the circular economy by the valorization of the green gas.

    The GAYA project, optimizing the use of forest residues

    GAYA project

    The platform produces biomethane from residues from the forest-wood sector. It mainly uses wood chips, enriched with a mixture of agricultural or industrial co-products: olive kernels, almond hulls, bark, or non-food straw. In order to reduce the carbon footprint, it is located close to gas transmission or distribution networks and large gas consumers such as boilers used for heating networks. The resources are also within a radius of less than 50 km. It is a local process of recycling of waste into energy.

    Kwinana Industrial Council

    Kwinana Industrial Council

    Companies in the industrial area south of Perth, in Australia, have chosen to work together to develop synergies and preserve the resources. The cogeneration plant operated by ENGIE in this area contributes to the establishment of a circular economy, particularly through the reuse of industrial water.
