The pellet production of the company Sturmberger is a prime example of the ecological production of a regional energy source. Chips from nearby sawmills are dried with the waste heat from a waste incineration plant, processed into pellets and then sold to households in the immediate vicinity – a regional economic cycle that transforms sawmill by-products into energy and climate that relieves the climate and the environment. The CO2 reduction when using wood pellets is 99% compared to heating oil. The success story of the Sturmberger Group began more than 20 years ago, meanwhile Sturmberger Pelletproduktions GmbH alone has 50 employees.

Marianne and Franz Sturmberger founded the first company and since then have rapidly expanded the product range from originally only bark mulch to wood chips and then also pellets. The capacities were constantly increased and expanded. Meanwhile, about 45,000 tons of pellets are produced each year and thus cover the annual demand of around 9,000 households. Sawmill by-products from the region. The pellets of Sturmberger GmbH are produced exclusively from by-products of nearby sawmills. When processing spruce and fir in the sawmill, planing and sawdust occur. These are the raw material for the high-quality pellets from Sturmberger. Drying with energy from a waste incineration plant An ecologically particularly sensible way of drying the sawmill by-products into pellets prior to their processing was selected in Wels.

A local waste incinerator supplies the heat which is used to dry the wet sawdust. By exploiting this synergy effect, 30,000 tonnes of CO2 are saved every year. Renewable energy for pressing. The pellet plant receives the electrical energy for the presses from a local electricity supplier. This, generates electricity to 90 percent from renewable energy. Local supply. The produced pellets are consumed in the region within a radius of 60 km. In comparison to the transport of fossil fuels, these short transport routes only cause extremely low CO2 emissions. Efficient technology. The Welser Pelletwerk relies on the so-called pellet tower technology of the Austrian producer Teccon. This technology guarantees first-class quality, only ENplus certified pellets of class A1 are produced, and maximum efficiency in production. The investment in a large warehouse at the main site consolidates Sturmberger’s role in the market and secures the supply of regional pellets even in phases of particularly high demand.
