ACCIONA places sustainability and positive impact at the core of its strategy. In the water sector, there is an opportunity to drive innovative solutions that improve operational efficiency in industries and contribute to the decarbonisation of their processes. Within this framework, exploring biological elements capable of capturing CO₂ and other contaminants becomes a promising pathway toward cleaner and more sustainable models.

The use of biological elements capable of capturing CO₂ and other contaminants not only contributes to emissions reduction and process decarbonisation but also improves energy ratios and has a direct positive impact on the surrounding environment.

ACCIONA is launching this challenge to find technological solutions capable of transforming waste into valuable products — for example, by leveraging by-products to generate new materials or resources. Solutions applicable to water cycle infrastructure that enable valorisation of waste, reduction of environmental footprint, and creation of products with positive economic, environmental, and social impact will be prioritised.
