The truck has the capacity for one stack more than standard timber vehicles and contributes to reducing heavy traffic when trasporting timber.“To date, the ETT-vehicle has demonstrated only positive impacts on the environment,” says Thomas Hedlund, Logistics Manager North at SCA Skog.The trial with the ETT vehicle commenced in 2009 and will continue for three years. The project is headed by Swedish forestry researcj institute Skogforsk, which is cooperating with several different partners, of which SCA is included as a land owner.“The environmental saving is slightly more than 20 percent. For example, it saved 56,000 liters of diesel and 140 tons of carbon dioxide,” says Thomas Hedlund.An ETT vehicle weighs 90 tons, is 30 meters long and operates between the timber terminal in Överkalix and SCA’s industries in Munksund, Piteå, a one-way distance of 160 kilometers.
