Products and co-products that cannot be recycled by industrial actors must be stored in a secure and controlled manner. The storage methods differ according to a serie of characteristics that are specific to the nature of the production process, the waste and the overall context of the site.

Waste storage is conventionally liquid (settling tanks) or solid and is in a context associated with major issues such as:

• Obtaining or regularizing operating licences
• The risk of dykes instabilities (settling basins) and stockpiles (stacks of solid materials) that could generate potentially significant contaminations downstream of the site;
• The risks of leaching of waste into the groundwater and its subsequent contamination.

ARTESIA uses its expertise and predictive tools to address these issues by:

• Effective communication;
• Tailor-made technical solutions for geometric storage design, leachate collection system, groundwater monitoring network, basal sealing complex coupled with efficient drainage system;
• The choice of optimal technical alternatives;
• Optimisation of geographical storage choices according to the hydrogeological context, the nature of the waste and the related health risks;
• The return on investment calculation of the construction of new storage sites.

In this way, our customers benefit from efficient administrative regularisation of their waste exploitation while making optimized strategic choices under the environmental, economic and social constraints they face.
