Stolt Tank Containers pursues the highest standards in quality, safety and sustainability. Our sustainable innovations are implemented through staff training and compliance with a broad range of policies and regulations, ensuring positive outcomes for people and the planet, while providing the best service to customers.

Our focus on building a sustainable business will keep our momentum going across the board, while placing extra effort on environment-related matters where we have the most room for improvement. We are currently developing a more structured way of measuring our carbon footprint. This will include measuring water, electricity, gas/petrol and steam consumption, waste management and employee commutes. Within the supply chain, we’ll be looking at emissions produced by downstream transport and distribution of our tank containers via third-party trucks, barges, carriers, etc.

We are committed to operating in a sustainable manner by focusing on the following fundamentals to drive us forward:

  • Providing the easiest, fastest and most flexible customer experience
  • Abiding by our commitment to safety of zero harm
  • Attracting and retaining high quality, motivated people and developing jobs into careers for all our staff
  • Fostering a culture of innovation that sets us apart from the competition and which we constantly strive to improve
  • Constantly reinvest in our businesses, assets and people for long-term growth
  • Continuously pursue the reduction of the environmental impact of our businesses
  • Continually developing initiatives that will ensure the long-term future of STC and the environment in which we operate.

Environmentally-friendly ISO tank containers

Stolt Tank Containers’ rigorous maintenance and repair processes ensure its tank containers are typically used 100 times over many years. Once they reach the end of their lifecycle and are removed from the fleet, more than 90% of the materials are recycled. Tank containers are a far more sustainable alternative to flexi-bags which are discarded after each shipment, adding considerably to the global single-use plastics burden. It is estimated that on average each flexi-bag adds the equivalent of 7,000 single-use plastic carrier bags to landfill. That’s around 40kg of plastic. In addition, a higher product retrieval ratio from tank containers compared to flexibags means less wastage of shipped product too.
