We are looking for innovative solutions to increase the level of circularity of dismantled assets.

Concrete is the most used construction material in the world and one of the major contributors to climate change. The chemical and thermal combustion processes involved in the production of cement, a key input for concrete, are a large source of carbon dioxide (CO2) emissions.  

With reference to the circular economy, we are addressing one of the most important issues related to the huge quantities of concrete rubble created when facilities are demolished.

The aim is to find new ways to increase the percentage of recycled aggregates and concrete deriving from demolition works, and to recover this waste in industrial processes other than cement production.


Enel Global Energy and Commodities Management is looking for innovative solutions to increase the level of circularity of decommissioned assets.



Enel has to manage large quantities of aggregates and concrete that result from demolition which, in the absence of alternative solutions, would have to be disposed of in the traditional way. 



The aim is to find new ways to increase the percentage of recycled aggregates and concrete deriving from demolition works, and to recover these wastes in industrial processes other than cement production in Italy and Spain.

The solution must be:

  • Innovative: an alternative way to recycle and re-use concrete aggregates in addition to their use for the production of new cement

  • Sustainable: a positive impact on the environment and society

  • Local: to avoid or minimize the impact of transportation over long distances due to the large quantities of material



  1. The solution/project must be clearly structured: scope, goals, how to be implemented
  2. A draft of a business model with reasonable investment costs
  3. The solution has an Italian and Spanish context.
This challenge provides contribution to the following sustainable development goals (SDGs) to transform our world:
  • SDG 7: Affordable and Clean Energy;
  • SDG 9: Industry, Innovation and Infrastructure;
  • SDG 11: Make cities and human settlements inclusive, safe, resilient, and sustainable;
  • SDG 13: Take urgent action to combat climate change and its impacts;
  • SDG 15: Life on land.

Enel will evaluate the Proposals, getting in touch with the Solver if additional information is needed.

Following this preliminary evaluation, the Proposal(s) that meet the requirements of the challenge will be further evaluated by one or more relevant Enel companies and/or business lines.

Enel will evaluate the proposal using the following criteria:

  • Overall scientific and technical feasibility of the proposed solution;

  • Economic potential of concept (e.g. Total Cost of Ownership);

  • Business potential for Enel;

  • Novelty and non-obviousness;

  • Potential for proprietary position (i.e., is the technology novel or protectable);
