Peter Seppele Gesellschaft m.b.H.

Peter Seppele Gesellschaft m.b.H. is a medium-sized, family-run company with headquarters in Feistritz/Drau. Founded as a forwarding company in 1929, the business has gradually developed and successfully adapted to the constantly changing social requirements. Meanwhile, the main fields of operation are in the areas of waste management, solid and liquid fuels and insulation materials.

For three generations now, the Peter Seppele Gesellschaft m.b.H. has been driven by its guiding principle of “Put it to use, don’t waste it“ - a striking demonstration of how it is possible to combine environmental consciousness with corporate success.
