The execution of Soletanche projects requires the use of materials associated with CO2<\/sub> emissions, such as cement, concrete, steel, and fuels. We are fully aware of the environmental impact of our operations. That is why we consistently take action to protect the environment by implementing eco-friendly solutions at every stage of project delivery \u2013 from planning to execution.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div>
Our commitments for the world of today and tomorrow<\/strong><\/h2><\/h3><\/div><\/div><\/div><\/div>
We are committed to reducing the carbon footprint of every project and of our operations through three key actions:<\/p>\n
\nDelivering assets with a positive environmental impact (clean transport, water quality improvement, energy-efficient buildings, etc.).<\/li>\n Leveraging technical expertise to reduce the environmental impact of investments (equipment powered by renewable energy sources or alternative fuels, low-carbon materials, optimized design options, etc.).<\/li>\n Implementing environmental measures on construction sites (waste segregation and recycling, recovery of raw materials and construction products, water saving, fuel consumption reduction, etc.).<\/li>\n<\/ul>\n<\/div><\/div><\/div><\/div>

Implementation of low-carbon materials to reduce CO\u2082 emissions<\/b>:<\/b>\nEXEGY – the use of low-carbon concrete based on the Soletanche Bachy mix design.\u00a0<\/li>\n The Soletanche Bachy laboratory also develops other innovative low-emission materials, including cement-free concrete based on activated slag.<\/li>\n<\/ul>\nProcess optimization to reduce resource consumption<\/strong>:\nWe recover materials from soil-cement waste generated during jet grouting, reducing the need for disposal.<\/li>\n We use bulk AdBlue containers, reducing plastic consumption.<\/li>\n We have introduced decanter centrifugation technology to recover process fluids and reduce waste generation.<\/li>\n We apply superabsorbent dewatering systems, reducing spoil volume and the number of transport operations.<\/li>\n<\/ul>\nSustainable equipment and energy management:<\/strong><\/b><\/p>\n\nWe use eco-fuels in construction machinery.<\/li>\n We carry out periodic inspections and modernization of equipment and machinery.<\/li>\n We monitor exhaust emissions and upgrade our vehicle fleet.<\/li>\n We resell used oil and scrap metal for reuse.<\/li>\n We implement renewable energy sources (photovoltaics and geothermal systems).<\/li>\n<\/ul>\n<\/div><\/div><\/div><\/div>

Low-carbon concrete<\/h2><\/div>At Soletanche Poland, the use of low-carbon concrete is standard practice. In addition to environmental benefits, these mixes offer excellent physical properties, which are critical for geotechnical applications. In 2025, low-carbon concrete accounted for over 70% of the total concrete volume installed by our company,<\/p>\n<\/div>

Biofuels<\/h2><\/div>At Soletanche Poland, we are gradually introducing HVO100 fuel (hydrotreated vegetable oil) as an environmentally friendly alternative. Tested on drilling rigs and excavators of various types, this fuel reduces CO\u2082 emissions by more than 90% compared to B0 diesel. One example is the construction of the new TR Warszawa headquarters, where in 2025 we used approximately 10 m\u00b3 of HVO100 fuel, which was the only type of fuel used in our operating machinery.<\/p>\n<\/div>

In situ disposal of process slurries<\/h2><\/div>Our technologies use various types of slurries for the stabilization of excavations and boreholes. These can be divided into two main categories: bentonite slurries and polymer slurries. After completion of the works, each slurry is treated and disposed of using appropriately selected methods and resources. The standard method for bentonite slurry decomposition is decantation using a centrifuge. The volume of decanted slurry in 2025 amounted to 1,800 m\u00b3.<\/p>\n<\/div>

Construction material recycling<\/h2><\/div>At Soletanche Poland, we carry out research and development activities focused on the recycling of resources such as cement and water. This includes, among others, studies on the reuse of spoil material from jet grouting works. Our R&D projects are conducted in cooperation with leading Polish universities. In 2025, an engineering thesis based on implementation activities from one of Soletanche Poland\u2019s projects was defended at the Warsaw University of Technology.<\/p>\n<\/div>
