Closing the loop: How ISO tank containers support a more sustainable supply chain

Designed for longevity, built for circularity

An ISO tank container is built to last. With a service life of more than 20 years, each unit can be reused hundreds of times, reducing waste and the need for single-use transport packaging. At the end of its working life, around 90% of the tank’s materials can be recycled, keeping valuable resources in circulation and supporting the principles of the circular economy.

By contrast, single-use options such as flexibags often end up in landfill. Typically made from layered plastics and weighing over 40 kilograms, flexibags are difficult to recycle due to product residue and their mixed-material composition. In many cases, they are used once and discarded, creating unnecessary waste and environmental impact.

Responsible operations from start to finish

Sustainability  is embedded in every stage of ISO tank container operations - from design and manufacture to cleaning, maintenance and end-of-life recycling. Each step is closely monitored and audited, ensuring both environmental responsibility and product safety.

Unlike single-use systems, ISO tanks are professionally cleaned in certified facilities, allowing them to be safely reused for a wide range of products, including hazardous and high-value cargoes. This closed-loop approach reduces waste and ensures full traceability across the tank’s lifecycle.

Safety and efficiency at the heart of sustainable logistics

Sustainability in logistics goes beyond material choices; it also encompasses risk reduction, the protection of people, and maintaining operational integrity. ISO tank containers are designed with these priorities in mind. Their robust construction and standardised fittings minimise the risk of leaks or spills during loading, transit and discharge, helping to protect both people and the environment.

Supporting safer transport networks

Safety extends to the road as well. Drivers transporting ISO tank containers receive specialised training in handling liquid cargoes, ensuring stability and reducing risks during transit. This professional approach helps to prevent accidents, safeguard communities, and promote more reliable transport operations.

A smarter path to sustainable logistics

ISO tank containers embody a smarter, more responsible approach to liquid logistics. Their reusability, recyclability and built-in safety make them a proven choice for companies seeking to reduce their environmental impact without compromising on quality or efficiency.

As the industry continues to evolve, ISO tanks stand as a clear example of how sustainable design and responsible operation can deliver long-term value - for businesses, people and the planet.
