Environment

Environmentally friendly

the society Guillouard, established since 1924 on the island Beaulieu in the heart of Nantes, is particularly respectful of its environment. We manufacture in France. Transport and carbon emissions are thereby minimized, which is favorable to the carbon balance.


The products used throughout the manufacturing process are identified and selected based on established criteria (environmental, health of workers, ...) and are stored in optimal conditions of safety. The used products (detergents, acids) and miscellaneous wastes are systematically removed by specialized companies that reprocess, recycle or destroy them.


The rinse water is recycled to 100% in-house with an physical-chemical effluent treatment plant , high performance. Guillouard is proud to be to "ZERO emissions" and to participate in the preservation of water resources and aquatic environments, and to be part of French models of an industry that cares about its impact on the environment.
The materials used to manufacture the items are recovered or recycled. Everyone knows that steel is infinitely recyclable and that his collect is easy. Zinc is also a recyclable material. Currently, about 30% of world zinc consumption comes from recycled zinc.
The wood that we acquire for the manufacture of our silos and garden plots is treated with environmentally friendly products, and the subject of a PEFC certification (Programme for the Endorsement of Forest Certification Schemes) which guarantees sustainable forest management.
Our packaging also are subject to special attention. We try to minimize them, and participate in the recycling effort by joining "Eco-Emballage".
We also adhere to "Eco-Systèmes", to whom we entrusted the removal and treatment of WEEE (waste electrical and electronic equipment).
