En la Autovía del Eresma (A-601), gestionada por Sacyr Concesiones, hemos puesto en marcha una solución innovadora para avanzar hacia una conservación más sostenible de las infraestructuras. Hemos reutilizado en un kilómetro material reciclado procedente del firme que retiramos para renovar la capa de rodadura.
La actuación incorpora un 30% de material fresado de la capa de rodadura envejecida de la autovía, que vuelve a emplearse en la fabricación de la mezcla bituminosa. Se trata de un porcentaje que duplica la recomendación de la normativa para este tipo de capas, fijado en el 15%.
Solución a largo plazo
Con este tramo de prueba, ubicado entre los puntos kilométricos 81 y 82 en sentido Segovia, buscamos demostrar que la tecnología desarrollada para la fabricación de mezclas recicladas permite incrementar significativamente el uso de material recuperado sin comprometer el rendimiento de la carretera.
“En este tramo de prueba reducimos el consumo de materias primas de la mezcla”, explica Miguel Ángel Moreno, del departamento de Firmes de Sacyr Concesiones. “Además, necesitamos llevar menos material al vertedero y reducimos la huella de carbono que se genera en la producción de los firmes”, señala.
La iniciativa permitirá evaluar el comportamiento de esta solución a largo plazo y analizar su potencial para futuras actuaciones de conservación.
“Queremos comprobar cómo funciona esta mezcla, si esta solución es sostenible, factible y rentable a largo plazo”, comenta Ángel Delgado, gerente de la Autovía del Eresma.
Tecnología y colaboración para innovar
La nueva mezcla reciclada, una mezcla discontinua tipo BBTM 11B con un 30% de material fresado, se fabricó en la planta de Padecasa, en Aldeavieja (Ávila).
El proyecto surge de la colaboración entre la Junta de Castilla y León, el departamento de Firmes de Sacyr, el área de Innovación de Sacyr Concesiones y Padecasa. Da continuidad al tramo experimental ejecutado en el verano de 2024, cuando empleamos un 15% de material procedente del fresado, el porcentaje máximo recomendado actualmente para este tipo de capas de rodadura.
Esta iniciativa se alinea con los principios de economía circular y con el marco normativo de Castilla y León, que establece que al menos un 3% de los áridos utilizados en las obras de rehabilitación de firmes deben proceder de materiales reciclados.
Con proyectos como este seguimos impulsando soluciones innovadoras que reducen el consumo de recursos naturales y favorecen una gestión más sostenible de nuestras infraestructuras.

Innovation beneath the surface at Binningup
An innovative repair was carried out on the transition chamber at our desalination plant in Perth, Australia, which not only maintained the integrity of the seawater intake system but also ensured that the marine environment was protected at all times.
One key component of the seawater intake system is the Stage 1 Transition Box, a buried concrete structure that connects two 1.6 m HDPE intake pipelines to the plant’s intake tunnel. Operating beneath the seabed in a challenging marine environment, this structure plays an important role in maintaining the integrity and reliability of the plant’s seawater intake system.
Following the identification of progressive structural degradation and sand ingress, Sacyr Agua worked closely with Water Corporation and specialist delivery partners to develop a low-impact remediation solution. The objective was clear: restore functionality and extend asset life without requiring full replacement of the structure.
Developed in collaboration with SEA Global, SF Design and Fremantle Commercial Diving, the solution involved the installation of a precision-machined modular HDPE lining system. Reinforced in key locations and grouted in place, it created a sealed, load-bearing internal flow path. Computational Fluid Dynamics (CFD) modelling, structural verification and full-scale dry and wet testing were used to validate the design ahead of offshore installation.
The project was delivered under demanding offshore conditions, including subsea construction, restricted access, limited weather windows and stringent environmental controls. Specialist diving teams installed more than 75 custom-machined HDPE components within the existing structure, restoring intake integrity while minimising disturbance to the surrounding marine environment.
“This was more than a repair – it was a coordinated effort across design, fabrication and marine execution,” said Paul Oosthuizen, Maintenance Manager at the Southern Seawater Alliance.
By rehabilitating the existing structure rather than replacing it, the project reduced seabed disturbance, minimised operational impacts and extended the service life of a critical element within the plant’s intake infrastructure.
Australian Water Award
In 2025, the Transition Box Remediation project received industry recognition through an Australian water sector award for innovation in marine infrastructure delivery.

Discover the species found around our projects
Our activities are carried out in natural environments where biodiversity plays a crucial role. Therefore, we are committed to protecting and preserving the ecosystems and communities with which we coexist.
11/09/2026
We work in natural environments where biodiversity plays a vital role. That is why we are committed to protecting and preserving the ecosystems and communities around them.
Caring for nature is not only about taking protective measures; it also means observing it, understanding it and appreciating its richness.
Colombia offers a good example. There, our colleagues Andrés Mauricio Forero Cano, a biologist in the Environmental Area of the Buenaventura-Loboguerrero-Buga project, and Manuel Alejandro Posso Gaviria, Environmental Birds' Route Project Coordinator at Unión Vial Camino del Pacífico who captured a series of images showcasing the fauna and flora found in the area. The photos were part of our RevelaVerde competition.
Andres Mauricio's photographs were taken in the Venado Verde Nature Reserve, in the area surrounding this road project.
“With these photographs, I want to show the immense biodiversity found in our region, particularly among amphibians and reptiles, a group that is still little known and often undervalued,” says our colleague.
“The photographs were taken using macro photography techniques. I used a Nikon D7200 camera with a 60 mm Laowa macro lens, external flashes and diffusers,” explains Andrés Mauricio.
Captured while work was underway, these five photographs bring us closer to a fascinating world of colors, shapes and behaviors that often goes unnoticed, yet plays an essential role in the balance of ecosystems.
The five photographs show:
1. Pacific lemur frog (Agalychnis psilopygion). “It is a species of incredible beauty and fragility that lives only in well-preserved forests.”
2. Cane toad (Rhinella horribilis). “This species has long been overlooked because of its appearance, but it plays a fundamental role in our ecosystems by controlling insect populations. Through macro photography, I wanted to capture its splendor and show that the world should look beyond appearances and recognize what lies beneath.”
3. Dwarf spiny iguana (Enyalioides heterolepis). “This lizard lives in the leaf litter of pristine forests and has a variety of scales that give it a striking appearance, which I wanted to highlight through macro photography.” The image won first prize in the Flora and Fauna category.
4. Glass frog tadpoles (Teratohyla spinosa). “These small glass frogs live in the vegetation that grows along streams. They lay their eggs in gelatinous clusters on leaves. When the eggs hatch, the tadpoles develop inside this gelatinous mass until they are large enough to drop into the streams and complete their development.”
5. Broad-headed anole (Anolis latifrons). “This photograph was taken with a wide-angle macro lens, combining the detail of macro photography with part of the animal’s surroundings. This lizard species lives in vegetation near streams. In the photograph, I wanted to capture both its remarkable details and the habitat where it is usually found.” (top photo)
These images remind us how important it is to coexist responsibly with local wildlife and to make nature protection part of how we deliver our projects. Learning about the species that live in the areas where we work is the first step toward helping conserve them.
Another colleague who participated in RevelaVerde with his photographs is Manuel Alejandro Posso Gaviria, Environmental Birds' Route Project Coordinator at Unión Vial Camino del Pacífico.

Poison dart frog (Oophaga anchicayensis). Located near the tunnels, along the Pepitas River. This frog is endemic to the region.
Photo 2. Blessed Fortune
Tree frog (Ecnomiohyla phantasmagoria). Located in San Cipriano. Virtually nothing is known about its ecology and behaviour, as this species lives high in the forest canopy, between 20 and 40 metres above the ground. It was discovered after a rainy night on a fallen branch. This species is literally a ghost, with only a handful of recorded sightings.

We rescued a turtle at our Skikda desalination plant
Our commitment to biodiversity is reflected in practical action, showing the responsibility and care our teams bring to the ecosystems around us.
A recent example took place at the Skikda Desalination Plant O&M Joint Venture in Algeria, where the plant team stepped in to rescue a sea turtle that had become trapped on the premises. Thanks to the team’s swift response, the animal was safely released and returned to the sea in good condition.
Zenina Hadjer, a laboratory technician and the author of the images submitted to the RevelaVerde competition, explains: “During operations at the plant, a sea turtle was found trapped in the facility’s intake basin. Aware of our responsibility to the ecosystem, our team acted immediately. We carefully rescued the animal and took it to Srigina Island, where it was safely released back into its natural habitat.”
“These images show how our industrial operations can coexist with the preservation of local biodiversity,” says our colleague.
Actions like this show that sustainability is also shaped by everyday decisions and efforts.
Thanks to our teams’ commitment and dedication, we help protect biodiversity and preserve the natural value of the environments where we operate.
