The Thermo-Rec system was created 20 years ago to address the problem of discarded tires in Scandinavia. Its inventor, Alf Johannson, worked nights and weekends over many years with the support of Chalmers University and local engineering companies to develop and patent the invention. After testing and endorsement by government and industry, Alf Johannson's wife and the marketing manager launched the system in his memory following his passing three years ago.
