Surface-active
agents or surfactants are very versatile and are used in many everyday applications.
They are used in detergents and in household cleaners, among other things but
also in the textile and oil industries, pharmaceuticals and agriculture. They
are manufactured on an industrial scale which provides an easily scalable lever
for more sustainable solutions, as a large proportion of these materials are
currently produced using petroleum derivatives such as ethylene oxide (EO).
The predecessor project “DreamResource” showed that it is possible to replace more than 16 percent of EO with carbon dioxide (CO2). CO2 was able to be used as an alternative component in reactive polyols such as rigid polyurethane foams, but also in surfactants. The joint project “DreamResourceConti” now aims to raise the level of technological maturity by optimizing the process and increasing the production scale. The project partners want to develop a continuous production process and expand the use of CO2 to additional areas of application.
The
main goal is to increase resource efficiency by using CO2 to
manufacture numerous products. The use of CO2 as an additional
component for surfactants broadens the raw material base for many applications.
In addition, the greenhouse gas CO2 is recycled in the material
cycle, which is an important step on the way to a functioning, climate-friendly
circular economy.
Two
academic partners and one company are joining forces in “DreamResourceConti”.
Besides the application-oriented, technical development, this cooperation also
has advantages when analyzing the results. The cooperation promotes
understanding through the intensive characterization and analysis of new kinds
of substances. In addition, ecological and techno-economic evaluations make it
easier to assess the potential of this innovation.
