About us

Susteco AB is a Swedish based company founded in 1997, market leader in providing solutions for on-site composting of food waste. The Big Hanna composter is a unique flow-through system which gives our customer a simple and practical way to compost food waste on site, avoiding storage, collection, transportation and landfill of organic waste. Our company acts locally through appointed distributors around the world. We and our distributors provide service contracts and support. We are always interested in finding new markets so please contact us at: info@susteco.se

The invention

The Big Hanna was invented by Torsten Hultin, a Swedish sociologist in 1991. Torsten wanted to create awareness about how the way our society uses and misuse its resources, and how dependent we are on our local and global environment. We cannot hope to reverse trends without changing our habits. On-site composting is a vehicle for education and empowerment – central solutions do not have the same impact.

Our long-term commitment

Today Big Hanna composters are installed in more than 35 countries. Our customers all have very high requirements on the economical and practical handling of their food waste. We have a vast experience from our many installations and can make sure that the chain from food waste to compost works as simply as possible.

Susteco AB is awarded an environmental diploma by the city of Gothenburg Environmental Administration. The diploma system is part of a process to build up an environmental management system that encourages continuous improvement.
