The sawn timber, produced at the traditional sawmill in Leoben, is delivered in 12 to 14 trips per day – currently accounting for up to 75% of the daily transport volume of sawn timber to the plant in Gaishorn – where it is processed into glued laminated timber and cross-laminated timber. Transportation takes place in two shifts from 6:00 a.m. to 10:00 p.m. Mayr-Melnhof Holz has signed a five-year contract with Herbert Temmel GmbH for this purpose.

The electric trucks are, of course, charged with green electricity! This is generated in the company's own biomass power plant with four boilers, where the bark of the round timber is converted into electricity and heat, in the new 3,800 kilowatt peak photovoltaic system, and in two hydroelectric power plants in the Göss-Graben.
To ensure that the trucks are ready for use, five loading bays have been set up in the sawn timber loading hall, which was built together with the new cross-laminated timber plant at the Leoben site and opened two years ago.
To ensure that the trucks are ready for use, five charging stations, each with a charging capacity of 350 kW, were installed in the sawn timber loading hall, which was built together with the new cross-laminated timber plant at the Leoben site and opened two years ago. 
While the sawn timber is being loaded, the trucks simultaneously charge their batteries (the battery capacity is 500 kWh). This means that the time is used twice. 

Some data: 
•    Distance between Leoben and Gaishorn: 106 km (round trip)
•    Consumption on one route: 142 kWh
•    Duration of a sawn timber loading: approx. 30 minutes
•    Charging time: approx. 24 minutes at 350 kW – perfectly matched to the loading time

The advantages
•    Significantly lower CO₂ emissions
•    Use of green energy generated at the plant
•    Another step toward sustainability
•    A sign of the company's innovative strength
•    Efficient use of loading and unloading times
