About us
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.
