Energy from waste –
sustainable and efficient.
Innovation and sustainability are at the heart of our waste recycling. We use thermal processes to convert energy-rich waste into high-quality secondary fuels, which are an environmentally friendly alternative to fossil fuels. These substitute fuels are mainly used in the cement, paper, fiber and chipboard industries and make an important contribution to climate protection. Discover the potential of a green energy source with us and shape the future of sustainable energy generation.


Who we are
ThermoTeam is a joint venture between Saubermacher Dienstleistungs AG and Holcim and has been a pioneer in sustainable waste recycling for over 20 years. Our state-of-the-art plant in Retznei, southern Styria, converts non-recyclable, energy-rich waste into high-quality substitute fuels and thus actively contributes to climate protection and resource conservation.
At ThermoTeam, we believe in a working environment that focuses on appreciation, responsibility and diverse development opportunities. Our employees are the key to our success. With individual training opportunities, strong team cohesion and a dynamic working atmosphere, we promote personal and professional development in equal measure.
Our processes meet the highest standards and are certified to ISO 14001 and ISO 9001. These awards reflect our commitment to quality, environmental awareness and sustainable solutions.
Waste utilisation: innovation for climate protection and the circular economy
ThermoTeam is a pioneer in the production of refuse-derived fuels (RDF), which are obtained from non-recyclable, energy-rich waste. Our state-of-the-art plant in southern Styria produces around 100,000 tonnes of high-quality RDF every year. These fuels replace fossil alternatives and support industries such as the cement and paper sectors on their way to a circular economy.

Plant in Retznei
Since our joint venture was founded in 2002, we have made an important contribution to climate protection by replacing fossil fuels with alternative fuels. Among other things, this has enabled us to reduce our consumption of 1.4 million tons of hard coal. At the same time, we promote recycling: every year, around 2,500 tons of recyclable materials such as scrap metal are sorted out and sent for further recycling.
Tailor-made fuel
The input for our substitute fuels includes separately collected production waste, non-recyclable plastics and pre-treated waste fractions. These are carefully prepared using a multi-stage technical process – including NIR sorting machines, magnetic separators and air separators. The result: high-quality fuels that meet our customers’ requirements.


Technology & Innovation
Our continuous investment in state-of-the-art technologies and our many years of expertise guarantee the highest quality and efficiency. ThermoTeam is a key player in the circular economy and combines climate protection with forward-looking economic efficiency. For example, the ash produced during co-processing in the cement industry is also used as a substitute raw material in accordance with ISO 4349:2024. Residue-free recycling makes an important contribution to the circular economy.
Certified quality for sustainable energy generation
Our products meet strict environmental and safety standards, certified by ISO and SURE. With an impressive substitution rate and continuous innovations, we are setting new standards in waste recycling and ensuring sustainable energy in the industry.
