Circular economy

Esteyco has always aimed — and now with all the more reason — to apply designs that achieve the maximum possible welfare for people with the minimum possible ecological footprint, leveraging the complexity of systems as much as possible and aiming to use the fewest possible resources: reducing the consumption of raw materials, energy, recycling, and reusing and improving the functionality and efficiency of systems.

In the current context it is essential to fine-tune practices in order to optimise the costs of the works we undertake, considering the life cycle of infrastructure: concept, building and use, while paying special attention to O&M costs. The industrialisation of processes, functional obsolescence and conversion to new uses, deconstruction techniques and the reuse of materials, integrated structures with no support apparatus or expansion joints … these are clear examples of practices that are consistent with circular-economy criteria.
