Resources & Circularity
Building a sustainable marine industry
The impact of resource use and circularity
The shipping industry plays a key role in global trade and travel, but its reliance on limited resources and high waste generation pose significant environmental challenges. From the raw materials used to build ships to the water consumption and waste generated during operations, resource use has a significant impact on marine ecosystems. Unsustainable practices can lead to resource depletion, increased greenhouse gas emissions and pollution, affecting marine life and coastal communities.
As the industry works to reduce its environmental footprint, resource efficiency and circularity are becoming essential. In the marine context, circularity means designing and operating ships with a focus on extending product life cycles, reducing waste and recycling materials wherever possible. By adopting a circular approach, the marine sector can reduce its dependence on non-renewable resources, minimise waste and make a positive contribution to the health of the oceans and global sustainability.
Reducing non-renewable resource use
A major challenge faced by the marine industry is its dependence on non-renewable resources such as fossil fuels, metals and minerals. As the demand for greener marine operations increases, a shift towards renewable or recycled materials is essential to reduce the pressure on natural resources.
Our brands demonstrate this commitment through concrete actions and innovations. For example, Vetrotech's Oraé low-carbon glass contains up to 70% cullet (recycled glass), achieving a significant 42% reduction in CO₂ emissions compared to traditional glass production. This breakthrough highlights how the use of recycled materials directly reduces the carbon footprint of shipbuilding.
At Isover, SEA CLIMAVER® helps to conserve resources by using up to 75% recycled glass wool in the manufacturing process, reducing the need for sand from quarries and helping to protect biodiversity. In addition, SEA CLIMAVER® reduces the use of additional tools and equipment compared to traditional metal ducts that require screwing and welding. This innovation reinforces Isover's commitment to minimising the use of resources while providing sustainable and efficient HVAC solutions.
Extending product lifetimes to minimise waste
One of the core principles of circularity is extending the lifespan of products, which in turn reduces waste and conserves resources. In the marine industry, where materials are exposed to harsh conditions, durability is key to minimising frequent replacements and the associated environmental impact. By choosing high-quality, durable materials, shipowners can reduce the frequency of replacements, conserving resources and minimising waste over time.
In addition, materials designed for longevity help reduce the volume of construction and demolition (C&D) waste, which is a significant issue for the industry. Durable products not only reduce the need for frequent replacements but also ensure that fewer materials are sent to landfills, supporting a more sustainable and circular approach to marine construction.
Saint-Gobain Marine designs materials that are built to last, even under the challenging conditions of marine environments.
For example, Kaimann's insulation solutions are designed to prevent condensation, reducing the risk of corrosion and ensuring long-term durability. These products are ideal for marine environments where maintaining structural integrity is critical to extending the life of components.
Similarly, Weber's screeds require no maintenance during use, contributing to operational efficiency. Upon demolition, 90% of the crushed concrete from screed-integrated slabs is recycled, demonstrating Weber's commitment to circularity and resource conservation.
By developing products with durability and recyclability, Saint-Gobain Marine helps owners create more sustainable marine operations. These solutions help to reduce the environmental footprint of shipbuilding while ensuring high performance and long-term value. Together, we are driving the transition to a more circular, resource-efficient future for the marine sector.
