Despite considerable progress, the coatings industry is still considered to be an energy-intensive and potentially environmentally hazardous sector. Stoz GmbH intends to serve as a role model here and for many years now has been actively involved in ecological management.

Emission of volatile organic compounds (VOCs)
In 2016 Stoz GmbH invested in thermal afterburning (TAB), and as a result was able to drastically reduce emissions of volatile organic compounds (VOCs). Since then, all our solvent-containing exhausts have been cleaned by combustion at 750°C. The heat generated is then used as process heat and for heating the buildings. The exhaust air cleaned in this way meets the strictest legal requirements. Thanks to this measure, it was possible to eliminate odour pollution and significantly reduce fuel oil consumption.

CO2 emissions
Reducing CO2 emissions to protect the climate is one of the most important goals for the future and has been set out in many multilateral agreements such as the Kyoto Protocol, the United Nations 2030 Agenda and the Paris Agreement. Stoz GmbH has set itself the goal of continuously reducing its CO2 emissions. By implementing targeted measures, the emission of this climate-damaging gas has been significantly reduced in recent years. Since 2013, all lighting has been switched to LED technology. In addition, Stoz GmbH has also been using electricity from 100% renewable sources since 2015 and was able to significantly reduce its heating oil consumption after the TAB was put into service. Since 2017, we have increasingly been focussing on CO2 as a cleaning medium, which has led to a slight increase in emissions. Here, however, emission does not take originate from combustion of a fossil fuel, but from the release of already existing CO2. In the future, we plan to switch from heating oil to gas for heat generation, which will allow us to further reduce our CO2 emissions.

The CO2 emissions sources include: Electricity usage, heating oil requirements, company vehicles, combustion/emission of VOCs, gas consumption and emission of CO2 as process gas
